Capital Budgeting for Trinity Hospital Case Study

Essays on Capital Budgeting for Trinity Hospital Case Study The paper "Capital Budgeting for Trinity Hospital" is a perfect example of a case study on finance and accounting. This particular SLP deals with the capital budgeting for Trinity Hospital’s project which is based upon the establishment of the new cancer research wing. This project is estimated to incur a cost of around $1 million and it will be completed in a period of years. It is assumed that the cost of capital would remain 15%. The new research wing is expected to generate around $250,000 in the second year and $500,000 in the next year. Revenues are projected to be increased by 25% each year after the second year. So as part of capital budgeting analysis of this new facility, NPV, IRR, MIRR, Discounted Payback Period and Profitability Index are calculated.On the basis of the above computations, the financial aspects of the company seem pretty sound. Overall, the company is in a very healthy financial position based on the financial highlights. There seems no uncertainty in the upcoming five years as per the prediction of cash flows. In the following paragraphs, item wise scrutiny is conducted to reflect the true financial forecast of the company with different financial projection techniques.NPVAs far as NPV of the project is concerned, a very handsome figure of around $0.8 million suggests that this project would be extremely viable for the company. Hence on this basis of NPV, the project can be selected by the company.IRRIRR of this project is also very attractive, generating a yield of around 42%, therefore on the basis of IRR, this project is highly profitable and should be opted by the company.MIRRSince no reinvestment rate was given in the scenario, therefore it is assumed that the company would be reinvesting every earned cash flow at the rate of 20%. As a result of assuming this rate, Modified IRR is calculated and yields around 33% return which is also very attractive.Discounted Payback PeriodSo far as Discounted Payback is concerned, this project would be covering all its initial investment near to the end of year 3 which is also very fruitful for the company as the company can enjoy the year 4 and 5 cash flows free.Profitability IndexProfitability Index is a derived technique of NPV. PI of greater than 1 also suggests that the project is viable. So for this project, PI is computed and the value arrived is 1.94 which suggests that the project is more than acceptable for the company.RecommendationOn the basis of the above commentary on the financial aspect of this project, it is advised to the company that they should select this project but must also consider the relevant qualitative factors that run beside the quantitative factors.

No one I ever knew growing up did this sort of thing and to me it all seems like a fantasy world sometimes and it’s very abstract. You know, I explain to my mother what I do and I can’t, you can’t put it into words, it just doesn’t make any sense. You can read also Portfolio Management Quizzes I am so removed from the daily life of the average person that I think at some point this has got to come to an end. Whether I really believe that or not I don’t know but in my head I kind of think this is all fantasy land and one day I’m going to wake up and I’m going to say I had the most amazing dream, I’ve been working on some place called Wall Street, that paid me lots of money and I just sat around and looked at computers all day and put these pieces together and everything worked out and it was all a lot of fun. So in my mind that’s kind of what I think. Derivatives Trader, ? rm B We live in a world that is shaped by ? nancial markets and we are all profoundly affected by their operation. Our employment prospects, Introduction our ? nancial security, our pensions, the stability of political systems and nature of the society we live in are all greatly in? uenced by the operation of these markets. The role and importance of international ?nancial markets and the traders who inhabit them has grown dramatically in the past few decades. You read "Traders- Risk, Decisions and Management" in category "Papers" The level of ? nancial ? ows in these markets can rise to quite staggering levels. For example, in the day before the setting of entry exchange rates to the Euro, trades in currencies entering the Euro totalled about ten times World gross domestic product (GDP). At any one time, outstanding derivatives contracts have a total value of around four times World GDP. Professional traders ? gure prominently in media accounts of the workings of ? nancial markets and the economy. Television news bulletins on the economy or stock market frequently include interviews with senior traders, or footage of a trading ? oor. Stories about ‘rogue’ traders are big news. The decisions of individual traders are often seen as having the potential to move markets and affect national economies. Yet, the role of the professional trader is largely absent from mainstream ? nancial economic accounts of markets. Professional traders, we argue, inhabit a borderland in markets where some of the orthodox assumptions of ef? cient, instantaneously adjusting prices break-down. They are often well placed to exploit market imperfections, by virtue of lower transaction costs, access to privileged information, critical mass, or proprietary knowledge and models. However, at the same time, they work in a fast-moving landscape of noise, rumour, unreliable information, and uncertainty. Thus, it is often dif? cult to tell whether an opportunity is real or illusory. This is a book about professional traders in this noisy borderland: what they do, the kind of people they are, how they perceive the world they inhabit, how they make decisions and take risks. This is also a book about how traders are managed and the institutions they inhabit: ? rms, markets, cultures, and theories of how the world works. Our approach to writing this book is explicitly interdisciplinary. We draw on psychology, sociology, and economics in order to illuminate the work of traders and their world. Our focus is traders and the ? rms they work in. It is not the purpose of this book to mount an extensive critique of the dominant rational–economic account of ? nancial markets, nor 2 Introduction is ‘markets’ our central focus. We are concerned principally with understanding the world of the professional trader. However, we do believe our work is relevant to an understanding of ? nancial markets. First, in order to understand the role and work of the trader, it is important to understand that the neoclassical paradigm of ef? ient markets and rational pricing breaks down at the margins and that professional traders both bene? t from and contribute to this departure from orthodox ? nancial economic theory. Second, the ef? cient markets paradigm rests on the assumption that in the absence of uniformly rational investors, there is a suf? cient group of rationa l investors who are able to drive out pricing anomalies through arbitrage. 1 Professional traders in investment banks seem good candidates to play this role. Hence, the evidence that we present on the ways in which traders can deviate signi? antly from rational– economic norms of behaviour may be fruitful in helping to explain market phenomena. 1. 1 Our Work and How It Informs the Book This book is based on a study of traders in ? nancial instruments in four large investment banks operating in the City of London. Over the course of 1997 and 1998, we carried out interviews with 118 traders and trader managers in four large City of London investment banks and collected qualitative and quantitative data on their roles, behaviour, performance, and psychological pro? les. We carried out followup interviews in 2002. We use detailed quotations from the interviews throughout the book. Where we use these quotes they are presented verbatim. We had three main concerns. First, we came to the study with a strong interest in decisionmaking and risk. While all business is concerned to some extent with risk, investment banks and ? nancial traders are almost unique in the extent to which their work is founded on the management of risk and the extent to which they must make decisions about risk. Second, in the vast literature on ? nancial markets relatively little attention has been paid to the role of ? ance professionals in these markets and we wanted to redress this. 3 Introduction Third, we observed that the large literature on markets and the (somewhat slimmer) literature on traders are marked by very different approaches and paradigms in three branches of the social sciences: economics, sociology, and cognitive and social psychology. We wanted to bring together the insights of these different disciplines. Throughout the book we draw both on the data we gathered in this study and on the insights of prior research and literature in ? nancial economics, psychology, an d the sociology of markets. We turn now to those literatures. 1. 2 Traders in the Social Science Literature Neoclassical Financial Economics Financial economics is a relatively young discipline. The origins of modern (neoclassical) ? nancial economics are often located in the early 1950s in the work by Markowitz (1952) on portfolio theory. During this period, ? nance moved from a concern with describing the activities of actors in ? nancial markets to the construction of parsimonious models of markets founded on assumptions of rational investor behaviour. The central organizing idea of neoclassical ? nancial economics is the ef? ient markets hypothesis, which holds that price changes are essentially a random walk. All new information relevant to prices is incorporated into prices instantaneously (Fama, 1970). This central proposition and much of the theory which springs from it is founded on the idea that any asset which is not ‘rationally priced’ provides opportunities for pro? t, which will be in stantly taken up and cause prices to converge to the ‘rational’ level (i. e. arbitrage). This assumption is both illustrated and lampooned in the ? nance joke about two ef? cient market theorists who pass a $50 bill lying in the street. They leave it untouched and congratulate each other on realizing that if it presented an opportunity for pro? t someone else would have picked it up already. Even the strongest proponents of the ef? cient markets hypothesis do not claim that it represents a good description of the behaviour of individuals in markets. Rather it is claimed to be a good enough description, which should be judged on its predictions rather than its assumptions. 4 Introduction Fama (1970), who set out an early comprehensive account of the ef? cient markets paradigm, has more recently suggested that: Like all models, market ef? iency (the hypothesis that prices fully re? ect available information) is a faulty description of price formation. Following the standard scienti? c rule, however, market ef? ciency can only be replaced by a better speci? c model of price formation, itself potentially rejectable by empirical tests. (Fama, 1998: 284) The ? nance professional is largely absent from orthodox ? nancial e conomic accounts of markets. The assumption of ef? cient markets, with no privileged information held by any investor, leaves little room for an account of how professional investors might make better than market returns. However, more recently, there has been an increasing interest within ? nancial economics in explaining empirically observed departures from the predictions of the ef? cient markets hypothesis and rational–economic pricing theories. Many of these fall in the emerging ? eld of behavioural ? nance. What has allowed consideration of the role different types of investor might play in markets is the growing recognition that perfectly ef? cient markets are not an automatic consequence of the existence of arbitragers: an idea that has been captured eloquently by Lee (2001: 284). I submit that moving from the mechanics of arbitrage to the [ef? cient markets hypothesis] involves an enormous leap of faith. It is akin to believing that the ocean is ? at, simply because we have observed the forces of gravity at work on a glass of water. No one questions the effect of gravity, or the fact that water is always seeking its own level. But it is a stretch to infer from this observation that oceans should look like millponds on a still summer night. If oceans were ? at, how do we explain predictable patterns, such as tides and currents? How can we account for the existence of waves, and of surfers? More to the point, if we are in the business of training surfers, does it make sense to begin by assuming that waves, in theory, do not exist? A more measured, and more descriptive, statement is that the ocean is constantly trying to become ? at. In reality, market prices are buffeted by a continuous ? ow of information, or rumours and innuendos disguised as information. Individuals reacting to these signals, or pseudo-signals, cannot fully calibrate the extent to which their own signal is already 5 Introduction re? ected in price. Prices move as they trade on the basis of their imperfect informational endowments. Eventually, through trial and error, the aggregation process is completed and prices adjust to fully reveal the impact of a particular signal. But by that time, many new signals have arrived, causing new turbulence. As a result, the ocean is in a constant state of restlessness. The market is in a continuous state of adjustment. Lee argues that the relationship between inef? cient pricing and arbitragers may be like predator–prey dynamics. In equilibrium there must be both predator and prey. Similarly, in equilibrium there will be both arbitragers and arbitrage opportunities in the market place. There is another important way in which ? nancial markets are widely accepted as departing from the ef? cient markets paradigm. Investors trade much more often than the theory suggests they should. More recent ? nancial economics accounts often distinguish two types of investors: ‘noise traders’ and ‘smart traders’ (a recent example is Daniel, Hirshleifer, and Teoh, 2002). Noise trading is trading on the basis of information that is either irrelevant to price or has already been discounted by the market. ‘Smart’ traders are those who act rationally, trading only on the basis of genuinely new and relevant information. This distinction is sometimes taken to map on to the difference between naive investors and trained professional investors (e. g. Ross, 1999; Shapira and Venezia, 2001). Behavioural Finance There has been increasing interest within the ? eld of ? nancial economics in using what is known about persistent biases in human cognition to explain departures of market behaviour from the predictions of ef? cient markets theory. Collectively known as behavioural ? nance, these models and empirical studies generally seek to explain market behaviour that departs from the predictions of orthodox ? ancial economics by reference to systematic cognitive bias among investors or important subgroups of investors. 3 Behavioural ? nance draws heavily on work from behavioural decision-making, a branch of psychology concerned with modelling human decision-making processes. While, in the main, this literature does not distinguish between professional traders and other investors, there have been 6 Introducti on some attempts to compare the susceptibility to biases of ? nance professionals to that of the wider population. For example, Shapira and Venezia (2001) found professional brokers less susceptible than independent investors to one common bias, the disposition effect (a bias towards selling stocks more readily to realize gains than to realize losses), although they were not immune to the bias. In an experimental study Anderson and Sunder (1995) compared the behaviour of laboratory markets populated by experienced commodity and stock traders with the behaviour of markets populated by MBA student traders. They found the amount of trading experience to be an important determinant of how well market outcomes approximated (ef? ient market) equilibrium predictions. Student traders’ markets exhibited departures from rational prices founded in common cognitive biases while bias levels in markets with experienced traders were substantially lower. However, as we explore in Chapter 5, our own research offers evidence that professional traders are just as susceptible as other groups to some forms of bias, with important consequences for their behaviour and performance. Sociology of Markets Sociologists interested in markets have paid rather more attention to the role of professionals than have ? ancial economists. Unlike ? nancial economists who take markets to be naturally occurring, sociologists tend to stress the ‘social embeddedness’ of markets and the ways in which they are sustained as social institutions through active intervention and regulation. One important strand of work is concerned with the social networks that operate within markets and in particular the ways in which professionals within markets act through these social networks and exercise informal sanctions over participants departing from accepted norms of behaviour (e. g. Baker, 1984a; Abola? a, 1996). Research by ? nancial economists also demonstrates the signi? cant effect the detailed structure and organisation of markets4 can have on the ? ow of information, liquidity, and prices (e. g. Amihud, Mendelson, and Lauterback, 1997; Lipson, 2003). Others have been concerned with the nature and consequences of ? nancial economic theory. Traders, from this perspective, do not simply inhabit markets; they enact them. That is, the beliefs they hold 7 Introduction about the nature of markets affect those markets in non-trivial ways. MacKenzie (2002), for example, describes how the adoption of the Black–Scholes equation for option pricing by traders did not simply enable more effective pricing of options, but helped to bring about conditions that better ? tted the assumptions on which it was based. The close empirical ? t between the predictions of the equation and options prices was bought about, at least in part, by the use of the equation to identify arbitrage opportunities. The empirical ? t has deteriorated subsequently as beliefs have changed to incorporate, inter alia, changed beliefs about the likelihood of market crashes. We pick up this theme of the re? exive relationship between beliefs and markets in Chapter 4. 1. 3 Overview of Book Chapters 2 and 3 set the context for our study and exploration of the role of traders. Chapter 2, ‘The Growth of Financial Markets and The Role of Traders’, considers the growth of international ? nancial markets in a historical context and outlines the role investment banks and professional traders have come to play. In Chapter 3, ‘Economic, Psychological, and Social Explanations of Market Behaviour’, we take a more detailed look at differing economic, psychological, and social explanations of market behaviour. Chapter 4, ‘Traders and Their Theories’, considers the nature of traders’ knowledge and the interplay between their subscriptions to theories of the ‘way the world works’ founded in neoclassical ? nancial economics and their more particularist and idiosyncratic theories of ‘how to work the world’. Chapter 5, ‘A Framework for Understanding Trader Psychology’, starts by outlining a psychological model of the trader founded in a selfregulation framework. It draws on the qualitative and quantitative evidence that we have about trader decision-making and bias. It challenges the ? ancial economics dichotomy between rational and non-rational and explains the different rationalities that arise as a consequence of internal goal states. We also present evidence on the vulnerability of traders to control illusions and the consequences for their performance. 8 Introduction Chapter 6, ‘Risk Takers: Pro? ling Traders’ presents a new model of risk taking that shows how trader behaviour emerges from a web of circumstantial and individual causes. The remainder of the chapter explores these individual differences in greater depth, especially how personality impacts different kinds of risk taking and decision-making. The chapter explores what kinds of people traders are, focusing particularly on personality and risk propensity, but also drawing on what we know about their demographics and background. Chapter 7, ‘Becoming a Trader’, uses a career transitions framework and a model of social learning to frame trader development and entry into a community of trading practice. We examine the ways in which they both learn and construct knowledge about the process of trading. In Chapter 8, ‘Managing Traders’, we explore the ways in which traders are monitored and managed within investment banks. We highlight the fact that traders are often not ‘managed’ at all, so much as monitored. Our concluding chapter (Chapter 9) draws together the implications of our ? ndings for traders, their management and regulation, and for further research. Notes 1. Arbitrage: purchasing currencies, securities, or commodities in one market for resale in others in order to pro? t from price differences. The effect of arbitrage is to act as a mechanism to bring about convergence of prices in different locations and markets or between equivalent securities. . A more detailed account of the sample and methods is given in the appendix. 3. We give a more detailed treatment of behavioural ? nance arguments in Chapter 3. 4. Often referred to as the institutional microstructure. 9 Chapter 2 THE GROWTH OF FINANCIAL MARKETS AND THE ROLE OF TRADERS Hardly a day passes without newspapers and television carrying a story about ? nancial markets and their impact on our lives. Even a casual perusal of these news stories makes it apparent that the activities of ? ancial institutions and markets have come to play a central role in our economic well-being and security: whether through their direct impact on individual investments and pensions or through their pervasive impact on the level of economic activity within nations and across the globe. The last decade of the twentieth century was marked by a series of international ? nancial crises. These underlined both the interdependence of national economies and ? nancial markets and the global scope of those markets. Financial crises in Latin America, the Asian Tiger economies, and Russia highlighted the speed at which capital can ? e Growth of Financial Markets countries in which investors have lost con? dence and the impotence of national governments to control such out? ows. The impact around the world of these crises on economies and ? nancial institutions demonstrated the highly interconnected nature of ? nancial markets. In the same period a number of ? nancial institutions suffered very signi? cant ? nancial losses as a consequence of the actions of single traders. One of the best publicized of these was Nick Leeson’s role in bringing about the collapse of Barings Brothers, in 1995. The collapse of Barings caused Alan Greenspan of the US Federal Reserve to comment that It is probably fair to say that the very ef? ciency of global ? nancial markets, engendered by the rapid proliferation of ? nancial products, also has the capability of transmitting mistakes at a far faster pace throughout the ? nancial system in ways that were unknown a generation ago . . . Certainly, the recent Barings Brothers episode shows that large losses can be created quite ef? ciently. Today’s technology enables single individuals to initiate massive transactions with very rapid execution. Clearly, not only has the productivity of global ? nance increased markedly, but so, obviously, has the ability to generate losses at a previously inconceivable rate. Moreover, increasing global ? nancial ef? ciency, by creating the mechanisms for mistakes to ricochet throughout the global ? nancial system, has patently increased the potential for systemic risk. (Greenspan, 1995) While the behaviour of individual traders has at times seriously damaged the ? rms they work for, individual ? nancial institutions have also shown the capacity to endanger the stability and operation of ? nancial markets around the world. In 1998, the collapse of Long Term Capital Management, a hedge fund holding positions in ? nancial derivatives with a notional value of $1,250 billion seriously endangered the stability of the world’s ? nancial systems. How could a single trader bring down a bank? How could a single hedge fund threaten the stability of the world’s ? nancial systems? The answer lies in the way in which ‘derivatives’ allow for the multiplication of market risks (and returns). The very features that make derivatives1 so useful as a tool for managing risk provide for the possibility of massively increasing risks. In this chapter, we argue that the role of ? nancial markets, in both world and national economies, has increased dramatically. 11 Growth of Financial Markets The potential, and sometimes actual, impact of individual traders on ? rms, markets, and economies is enormous. In the following chapters we show that ? nancial markets are neither as rational nor as natural as ? nancial economists paint them and that we need to bring a wider range of social science theory to bear on understanding traders, their ? rms, and the markets they operate in. As we show below, the current globalization of ? nancial markets is not new but simply the latest of several cycles of international ? nancial integration over two millennia. In particular, the recent growth in international ? nancial markets could be seen as a return to levels of international ? nancial integration seen at the end of the nineteenth century and interrupted by a period, which included two world wars and the Great Depression. However, the depth and scale of these markets does seem to be different this time and the emergence of new forms of ? ancial instruments, derivatives, capable of massively multiplying possible risks and returns has led to a qualitative difference in the potential impact of individual actions on institutions, markets, and economies. 2. 1 A Brief History of Financial Markets International ? nancial markets are not a purely modern phenomenon. Basic forms of ? nancial exchange can be found throughout recorded history and international ? nancial system s are known to have existed two millennia ago. Historical evidence suggests that there have been a series of cycles of international ? nancial integration (Lothian, 2002). In the three centuries following the collapse of the Roman Empire, currencies were very unstable and constantly debased. However, in the fourth-century AD, the Emperor Constantine introduced a stable gold coinage, the bezant (also known as the nomisa or solidus). This became widely used throughout the Mediterranean region. It was produced in Byzantium till the thirteenth century and kept more or less the same gold content through till the eleventh century. Until the introduction of the dinar in the Muslim world in the seventh century, it had no competitors as an international medium of exchange. While records are patchy, it is clear that the existence of a stable medium of international 12 Growth of Financial Markets exchange during the period between the fourth and eleventh centuries allowed quite sophisticated ? nancial transactions to take place (Lopez, 1986; Lothian, 2002). The thirteenth century was another period of growth in international trade, both within Europe and between Europe and other parts of the world. Much of this was organized around regular international trade fairs (most notably at Champagne and Brie). This period was marked by the growth of an extensive and sophisticated banking system and by the development of ? nancial instruments such as bills of exchange (which acted jointly as a credit and foreign exchange transaction). It is clear from the records of the dominant northern Italian banks of the time that not only were there quite sophisticated foreign exchange markets, but also that arbitrage was a common activity (Lothian, 2002). During the fourteenth century the importance of these trade fairs and the Italian banks declined. By the ? fteenth century, Amsterdam was the more important centre of ? ancial activity. The sixteenth century saw the development, in Amsterdam, of negotiable ? nancial instruments such as discounting commercial paper and, by the seventeenth century, the development of perpetual bonds, futures contracts, selling short, and other such ? nancial instruments and techniques that would be easily recognized in modern ? nancial markets (Homer and Sylla, 1996; L othian, 2002). By the start of the eighteenth century, the Amsterdam Exchange, the centre of Dutch trading, had become a world market in which a wide range of commodities and securities were traded. During this period, London took on increasing importance as a centre for international ? nancial trade. With the establishment of the Bank of England and the London Stock Exchange and the intervention of the Napoleonic wars, London came to eclipse Amsterdam as a ? nancial centre by the start of the nineteenth century. The nineteenth century saw a marked expansion of international trade and further development of ? nancial markets. The growth of the US economy drove much of this expansion. The New York Stock Exchange was established in 1817 and by the end of 1886 it hit its ? st day on which more than a million shares were traded. By the late 1920s New York had overtaken London as a world ? nancial centre. However, the early twentieth century, a period that included two world wars and the Great Depression, saw the collapse of international 13 Growth of Financial Markets trade and the rise of national regulation and controls on international ? ows of capital, which effectively unwound the integration of international ? nancial markets. Rajan and Zingales (2003) show that on a range of indicators of ? nancial development including stock market capitalization as a proportion of GDP, world ? ancial markets did not regain their pre-war (1913) levels until the late 1980s. The second half of the twentieth century once again saw a very substantial increase in international ? nancial integration. As we have seen, there is historical evidence that the current period of globalization of ? nancial markets is not a new phenomenon. Rather there have been cycles of high international integration of markets interspersed with periods of low integration throughout the last two millennia. However, it is also clear that with each new cycle the nature and depth of those markets has been changing. Changes in the sophistication of ? ancial instruments and technologies, and changes in communications and information technologies have all been important factors in? uencing the scale and complexity of ? nancial markets. The period since the 1970s has seen a very substantial increase in the size of ? nancial markets.

By 2002, outstanding over-the-counter derivatives3 (OTC) contracts had a notional value of $128 trillion, around four times greater than total world GDP. Figure 2. 3 shows the growth in number of active contracts between 1992 and 2002. Much of the recent concern about systemic risks in markets has centred on the role of derivatives. All ? nancial investments carry risk. However, there is a difference of degree with derivative trading. They involve contracts which are contingent on the price of underlying assets and because of the way in which trades are regulated, derivatives4 enable investors to speculate on the price of an asset while only depositing a small proportion of the underlying asset price (margin requirements) (Zhang, 1995). In other words, the ? nancial risk borne in an options trade may be many times the money actually deposited to make the trade. Financial ? rms which do not have sophisticated control mechanisms to manage their exposure to derivatives risk may 15 Growth of Financial Markets 000 Gross market value ($ billion) Gross market value 6000 5000 4000 3000 2000 1000 0 92 93 94 95 96 97 98 99 00 01 19 19 19 19 19 19 19 19 20 20 20 02 160 000 Notional amounts 120 000 100 000 80 000 60 000 40 000 20 000 0 Notional amounts ($ billion) 140 000 Fig. 2. 3 Global growth in OTC derivatives—global value of outstanding contracts Source: 2000–2, Bank for International Settlements; 1994†“9, Swaps Monitor publications Inc. unwittingly ? nd themselves exposed to potential losses greater than the total ? rm assets. Such risks can emerge very rapidly in the course of trading and require analysis of the whole ? m’s current portfolio of trading assets in real time to identify potential overexposure to market risk. Of course, the leveraging effect of derivatives does not only affect market risk but also ampli? es risk in the other categories. For example, since derivatives typically have greater volatility than the underlying asset, even a short period in which a ? rm is unable to trade (say due to computer failure) could result in signi? cant risk exposure. The complexity of some derivatives may mean that managers are ill-equipped to understand the trades dealers are engaging in, increasing behavioural risk (Chorafas, 1995: 16). In evidence given to the US House of Representatives, George Soros, a highly successful ? nancial speculator, said of derivative instruments: There are many of them, and some of them are so esoteric, that the risks involved may not be properly understood by even the most sophisticated of investors. Some of these instruments appear to be 16 Growth of Financial Markets speci? cally designed to enable institutional investors to take gambles which they would otherwise not be permitted to take. For example, some bond funds have invested in synthetic bond issues that carry a 10 or 20-fold multiple of the risk within de? ed limits. And some other instruments offer exceptional returns because they carry the seeds of a total wipe out. (Soros, 1995: 312) 2. 2 The Role of Investment Banks in Financial Markets To understand the role of modern investment banks it is necessary to understand how world ? nancial markets have come to be dominated by an American model of ? nance. Much as Byzantium, Lo mbardy, Amsterdam, and London have been the dominant centres of ? nancial innovation and power in previous eras, US ? nancial markets and institutions are today. The central feature of the US model that emerged in the post-war years was the decline of relationship banking and the increasing commoditization of ? nancial products and services. The roots of this system lie in the unintended consequences of anti-trust and banking legislation passed in the United States during the 1930s. The segregation of commercial and investment banking in the United States laid the foundation for the development of a strong investmentbanking sector. The fragmentation of the banking industry, imposed by legislation, created conditions in which ? ancial transactions were more readily managed through markets than within large banks. The elimination of ? xed commissions for broking ? nancial instruments in 1975 provided a further impetus for competition. More and more, ? rms seeking to raise ? nance looked to impersonal markets rather than relationships with banking institutions. Progressively more transparent and liquid markets in both corporate debt and equity a nd the corresponding increased competition in these markets served as a signi? cant stimulus to ? nancial innovation. As these markets developed it became apparent to market participants and to the government that effective market operation could only be maintained through active intervention and regulation. A series of waves of external and self-regulation, often in response to market crises, led to the development of regulations and supervisory arrangements designed to contain insider manipulation of markets and ensure free 17 Growth of Financial Markets ? ow of information. On the demand side, the expansion of institutional investment (insurance, pensions, and mutual funds) stimulated and was stimulated by the growth of these ? ancial markets. The slower growth of ? nancial markets and institutions in other parts of the world meant that, as other countries began to follow the United States in opening up competition, US ? nancial institutions were well placed to play a major role. In the wake of the major changes in market regulation in 1986, the long-established London merchant banks were swept a way by the US-based investment banks and non-US owned European investment banks have increasingly adopted US approaches. The principal competitive advantage of American ? rms lay in their expertise in managing risk (Steinherr, 2000: 49). Investment banks manage risk in four main ways: they absorb risk for clients, they act as intermediaries for the diversi? cation of risk, they advise on the management of risk and they engage in proprietary trading—taking risk on their own account in the pursuit of returns (Casserley, 1991). Absorbing Risk Investment banks absorb risk for clients in a number of different ways. For example, when they act on behalf of a client they absorb credit risk (the risk the client will default on payment for the transaction and they are unable to unwind the transaction at a favourable price). They underwrite issues of securities (e. g. commercial paper5 to cover shortterm ? nancing needs), guaranteeing to buy from the client at a ? xed price should the security fail to achieve its expected price in the open market. They also play an important risk absorption role in trading markets. In some of these the bank will act as a market-maker,6 providing liquidity in a particular ? nancial instrument. The bank ? xes prices at which it will buy or sell a ? nancial instrument and stands ready to buy or sell at those prices even if there is no party to pass the transaction on to immediately. In return for the spread between these prices the bank absorbs the risk of the market moving against them. Risk Intermediation In other cases the bank will act as an intermediary for the diversi? cation of clients’ risk. This may be by acting as an intermediary in trading 18 Growth of Financial Markets markets or by putting together complex OTC deals that rely on aggregating (or disaggregating) ? nancial instruments provided by third parties. The banks bene? t from this intermediation work in two principal ways. First, they charge commission and second, they have access via their customers to information about order ? ws in the markets in which they operate. Such ? ow information provides opportunities to exploit temporary market imperfections and pro? t through trading on their own account. Risk Advice The risk advice role overlays risk absorption and risk intermediation. For example, the bank may play an important advisory role related to underwriting activities or in puttin g together a complex OTC deal. The role of the bank in providing risk advice to clients rests not just on technical skills and experience in managing risk, but also in a (sometimes) greater overview of the markets in which they operate. An important issue here is the tension between the bank’s desire to make pro? ts on its own account and to earn a return through providing effective advice and services to customers. This tension is re? ected to some extent in tensions which emerge in most banks between trading and sales desks. As we will see later in the book, banks vary in the priority they give to serving customer needs versus seeking opportunities for returns through trading on their own account. 7 Proprietary Trading In providing services to customers, investment banks build up information on order ? ws, they develop expertise in valuing particular securities or in economic fundamentals in particular sectors or countries, they build proprietary models of price behaviour and they build up data on historic behaviour of prices and relationships between them. This can place them in a better position to judge risks and returns than other market participants and opens up the possibility of earning good returns on their own account. This activity typically takes two forms: short-term (often intra-day) trades designed to exploit knowledge of temporary price ? ctuations linked to ? ows of orders in the market and longerterm trades, often based on arbitrage (exploiting pricing inconsistencies between different securities, markets, or time periods). 19 Growth of Financial Markets 2. 3 The Role Played by Traders The work of traders can be divided into three broad categories: trading on behalf of customers, market-making, and proprietary trading. 8 Traders acting on behalf of customers take the least risk on behalf of the bank, while proprietary trading potentially involves the greatest risk. However, in practice, the three spheres of activity often overlap. For example, a trading desk acting on behalf of clients may also have authority to take intra-day positions to bene? t from short-term price movements in the markets they operate in. Alternatively, in some circumstances, while not strictly acting as a market-maker, they may stand ready to create liquidity for important clients by buying or selling to those clients when they cannot ? nd a counterparty for their trades. As one senior trader told us: We are paid to be on the wrong side of the market for our customers. If we have an institution that pays us thirty million dollars a year in commissions, we will, on occasion at their request, be a buyer for them when there are only sellers on the market or be a seller for them when there are only buyers. When they’re in a more normal market environment where there is plenty of liquidity and good two-way ? ow, they don’t necessarily need our capital. In fact they prefer not to use our capital because all that does then is create another buyer or another seller in the market with them. But when the market is heavily tilted in one direction than the other, even the market’s selling off, there are much more sellers than buyers or a very strong market where there are much more buyers than sellers. That’s when they need us to step in and serve as that intermediary to facilitate the execution of their order. 9 Alternatively, a trading desk operating as a market-maker may combine this with some proprietary trading. One trader described the activity of his desk: We have a PL [pro? t and loss], budget of about $20m a year through plain vanilla market making with customers. However, we make about half the money in proprietary trading using the ? ow and information from customers—putting it on our book instead of putting it back into the market. For the ? rst half of this year we were number one for turnover in our niche with between 10% and 15% of the market. The 20 Growth of Financial Markets more that number increases, the better information we would have for proprietary trading, but we would probably start losing money from the market making function because prices would have to be so keen, so there is a balance. Equally, traders mostly engaged in proprietary trading will seek opportunities to generate customer business: I do proprietary business and I’m supposed to be doing proprietary but I interface with the ? ow desk so I would be looking at customer business trying to generate customer business. My slant is proprietary but I’m always trying to emphasise customer business using my positions. 2. 4 How do Traders Make Pro? ts? If, in ef? cient markets, price changes are essentially a random walk and all new information relevant to prices is incorporated into prices instantaneously (Fama, 1970), then how do traders make money? The ? st answer is that they charge commission for their intermediation and advisory role. By aggregating customer orders they can reduce transaction costs. However, as we will explore in Chapter 3, in practice, markets are not completely ef? cient and information asymmetries exist. Traders essentially earn economic rents10 by exploiting information advan tages. These may come from a number of sources, including information on asset ? ows within markets (e. g. from having a large customer base); privileged information on the economic basis for an asset price; proprietary databases allowing more accurate calculation of probabilities (e. . historical asset volatility for pricing options); models of the relationship between prices and economic fundamentals; models for extracting the information inherent in historical price changes of an asset and other related assets; and effective understanding of the ‘sentiment’ and likely behaviour of other market actors. All of these information advantages are potentially short-lived. The very act of trading may reveal information to other parties. Others may emulate models. Others may access the same sources of information. New information may wipe out the utility of earlier information. At the same time markets are in practice very ‘noisy’. That is to say, there is a lot of trading going on that is not based on information 21 Growth of Financial Markets genuinely relevant to the underlying value of an asset. Black (1986) noted in his presidential address to the American Finance Association that Traders can never be sure that they are trading on information rather than noise. What if the information they have is already re? ected in prices? Trading on that kind of information will be just like trading on noise. Traders can only earn above market returns, on average, over time, if they are genuinely trading on new and relevant information. However, on any individual trade it will be dif? cult to tell whether a positive outcome is the result of trading on information or of essentially unpredictable market movements (as a result of noise trading in the market, changes in sentiment, or new unexpected events). Similarly, for any individual trade it is dif? cult to determine whether a negative outcome is the result of trading on noise rather than information or the result of unforeseeable market movements. So it will often be the case that trading outcomes are not contingent on the trader’s strategy or information. Further, it will often be dif? cult to determine once an outcome is achieved whether the outcome was indeed contingent on a trader’s information and skill. While trading is a skilful activity, many trading outcomes are not contingent on skill. At the same time traders are highly motivated to establish causal relationships between information they hold and prices, since a signi? cant source of rent for any trader is the capacity to establish contingent relationships before others observe them. This problem of determining the links between behaviour and outcome for traders is one we will return to repeatedly in the book. While the detail of different trading strategies is not our principal focus, we describe some common trading approaches to set the stage for our later discussions. In order for traders to achieve better than average market returns, it is not suf? cient that markets are imperfect; it is also necessary they have some competitive advantage relative to others who seek to exploit those imperfections. Within this fast-moving and uncertain world, traders adopt a variety of strategies to exploit the information and expertise to which they have access. These can be divided into four main categories: insider strategies, technical strategies, fundamental strategies, and ? ow strategies. 22 Growth of Financial Markets Insider Strategies Insider strategies involve achieving advantage by exploiting privileged access to information (Casserley, 1991). Of course, some such strategies are illegal. It is, for example, illegal to exploit privileged access to advanced knowledge of company earnings news or potential takeovers. However, most of these strategies are concerned with perfectly legitimate attempts to build an information advantage over rivals. The extent to which it is possible to achieve such information advantages varies signi? cantly from market to market. For example, in relatively undeveloped markets such as the ‘emerging markets’ there may be frequent and persistent information asymmetries. In these circumstances, traders who are able to establish good personal networks may build an advantage, which enables them to anticipate price movements. However, in mainstream equities markets, the speed and ef? iency of information dissemination may make such advantages dif? cult to achieve. Insider strategies can improve a trader’s ability to anticipate market movements. However, as we noted earlier, it is often dif? cult or impossible for a trader to determine whether they have a genuine information advantage or whether their information is simply noise, already discounted by th e market. Technical Strategies If markets are perfectly ef? cient, then historic prices contain no information that can be used to infer future price movements. However, many traders claim to do just that. They seek to exploit market imperfections through the analysis of past price information. One form of technical trade concerns using patterns in price data to identify likely turning points in price trends (charting). Traders seek to identify trends early, buy into those trends and exit before the trend breaks. Many traders consider these patterns and trends in market prices to be driven by underlying investor sentiment. While there is some evidence that supports the existence of exploitable patterns in market prices (e. g. Kwon and Kish, 2002), many ? ancial economists are sceptical of their existence. Fama (1970) dismissed technical analysis as a futile undertaking on the grounds that historical prices have no predictive validity. However, more recent arguments against technical 23 Growth of Financial Markets trading strategies take a weaker position: that while there is some predictability in market movements, exploiting these does not, on average, make returns in excess of transa ction costs (e. g. Allen and Karjalainen, 1999). A second important technical strategy requires the analysis of historical price relationships between different ? ancial instruments. Traders scan markets looking for discrepancies in pricing relative to these relationships on the assumption that they will move back to the historical pattern. Often the gains on technical trades will be small and over short time periods, thus these trades often depend on an ability to identify opportunities rapidly and frequently. This allows the trader to make large numbers of such trades each making a small pro? t. To bene? t from such trading strategies requires the ability to trade at low transaction costs, frequently, with considerable IT support. Many traders use technical strategies to supplement other approaches. For example, a trader having established a trade on the basis of customer ? ow information may use technical information on trend behaviour to determine the precise point at which to take pro? ts or cut losses. Others, while fundamentally sceptical about strategies relying on historical trend data, assume prices will be driven to some extent by investors using such models. For example, one trader told us: A lot of traders are chartists and a lot of people here don’t like you looking at charts, they don’t believe in them. However, I look at a chart if I am putting on a large position, or looking for something to trade because if there are people out there who use charts as a model to trade, this will affect how things trade in the markets whether I believe in it or not. Fundamental Strategies Technical strategies are purely concerned with anticipating trends and pay no attention to the underlying economic basis for evaluation of the security being traded. By contrast, fundamental strategies are concerned with the fundamental relationship between economic value of the underlying asset and market price. Traders following these strategies essentially seek to use expertise and information in the accurate valuation of securities, on the assumption that market values will 24 Growth of Financial Markets converge to theoretical values. To the extent that traders can establish an advantage in valuation of securities, they may be able to earn pro? ts from identifying securities that are undervalued or overvalued by the market. One highly successful trader told us: I tend to take positions that depend a lot on central bank decisions e. g. nterest rates, so depend on macro economic position of the country, the judgement about how the Bank of England is going to behave and how the market is going to proceed. I try to put myself in Eddie George’s11 feet and try to understand. We have been building a model of Bank of England reactions to economic events. I have lunches with people who decide our interest rates and try to understand how they think . . . It all comes down to focus and compl etely immersing myself in an area. However, as with insider strategies it can be genuinely dif? cult for a trader to understand whether they have a genuine advantage in valuation. Further, as we will see in Chapter 3, trading on valuation advantage depends on the market converging to a value in a time scale over which you can ? nance a trade. Flow Strategies This strategy predicts prices as a function of demand and supply for securities in the market. Particularly for securities in which there is not much liquidity,12 large trades can shift prices signi? cantly. Where a bank has a large customer base in a particular niche, this can give them access to valuable market information, in particular, information on trading ? ows. These kinds of advantage are more readily achieved in OTC markets, which lack the transparency of trades organized through exchanges. However, in any given market niche, there will be a very limited number of ? rms that can capture suf? cient order ? ow information to give them a genuine advantage. Feldman and Stephenson (1988) studied the use of ? ow information in the US treasury bonds market. They suggest that through the use of informal information trading with customers, a ? rm with a 3–4 per cent share in trading may have a good sense of what is going on in 30 per cent or more of the market. However, they also show that medium sized players in these markets are often unable to exploit their customer relationships effectively. They argue that large players systematically 25 Growth of Financial Markets shut medium sized players out of information networks while providing good market information to smaller players who they mostly relate to as customers rather than competitors. As we have seen, ? nancial markets have a long history and have been through multiple cycles of global ? nancial integration over the last two millennia, but their development into domains of such immense complexity and global in? ence has occurred only within the last 50 years. The volume of trading and of traders has no historical precedent, nor has the complexity and variety of the instruments traded. Within this context, the activities of traders within investment banks are important not just to their customers, but also at the level of national and international economies. Naturally, these phenom ena have attracted the attention of academics and commentators, from a variety of disciplines, who have, as we shall show in the next chapter, different and sometimes competing explanations of what in? uences and explains behaviour within global ? ancial markets. Notes 1. Derivatives are ? nancial products, which depend on or derive from other assets. 2. Values in all ? gures are nominal (non-in? ation-adjusted). 3. OTC derivatives are not traded in an exchange but are contracted directly between the two contracting parties. 4. Exchange requirements generally only require traders selling options to deposit a proportion of the potential claim. Further, speculation using derivatives is often highly leveraged (funded through borrowed funds). 5. Market traded short-term corporate debt. 6. Market-makers stand ready to buy or sell an asset or class of assets. Typically a market-maker quotes a buy (bid) and sell (offer) price to a client before the client declares whether they wish to buy or sell. The spread between bid and offer both provides a return and some protection against market movements in the time taken for the marketmaker to readjust their holdings after a trade. 7. There are also important differences between the United States and the United Kingdom in how this tension is regulated. UK banks face fewer constraints on the relationship between customer business and proprietary trading. 26 Growth of Financial Markets 8. The types of ? ancial instruments dealt in by traders cut across these categories. Some traders specialize by a particular type of instrument (e. g. equities or bonds in a particular sector), others deal in a range of instruments related to a particular geographical region or sector. 9. See also Abola? a (1996) for a description of such market stabilizing behaviour by market-makers. 10. Returns in excess of the ma rket risk premium. 11. Eddie George was Governor of the Bank of England at the time of interview. 12. Liquidity: the availability of parties willing to buy or sell a security at any given time. 27 Chapter 3 ECONOMIC, PSYCHOLOGICAL, AND SOCIAL EXPLANATIONS OF MARKET BEHAVIOUR For at least forty years psychologists have amassed evidence that economic man is very unlike a real man and that reason—for now, de? ned by the principles that underlie expected utility theory, Bayesian learning and rational expectations—is not an adequate basis for a descriptive theory of decision making. De Bondt, 1998 I am in fundamental disagreement with the prevailing wisdom. The generally accepted theory is that ? nancial markets tend towards equilibrium and, on the whole, discount the future correctly. I operate using a different theory, according to which ? ancial markets Market Behaviour cannot possibly discount the future correctly because they do not merely discount the future; they help to shape it. Soros, 1995: 111 If we are to understand traders, we have to ? rst understand the markets they inhabit. Neoclassical economics has been extraordinarily successful in explaining most market beha viour in the aggregate. However, it has two principal weaknesses for our purposes. The ? rst concerns what it does not address and the second concerns some important failures at the margins. Neoclassical ? nancial economics treats markets as a given, or naturally arising. Investor preferences and risk appetites are treated as external to the model but predictably ordered and distributed. Markets are modelled as adjusting instantaneously with little attention to the detail of how such adjustments come about. While neoclassical ? nancial economic models effectively explain a great deal of market behaviour, there are some important failures at the margins. There is a wide range of anomalies which are dif? cult to explain within this paradigm. If markets instantaneously adjust and are perfectly ef? cient, then the only role for professional traders is as intermediaries who cannot earn above market returns, but ssentially earn commission as intermediaries. There is nothing to be earned by arbitrage activities or speculation. Indeed, it is not even clear within neoclassical accounts of markets that there is a role for intermediation. However, if we assume markets to be only nearly perfect and ‘sticky’, the trader’s role as someone with p rivileged expertise, tacit knowledge, and access to private information (within limits) makes more sense.

Loginova Olga Organizational buying behavior in Business tourism market Case Holiday Club Resorts Oy 50 pages, 1 appendix Saimaa University of Applied Sciences, Lappeenranta Business Administration, Degree Programme in International Business Bachelor’s Thesis 2011 Instructor: Ville Lehto The purpose of this Bachelor’s thesis is to provide understanding of the organizational buying behavior in Russian companies in context of business tourism market. This includes describing the general model of the process, identifying people, responsible for decision making and analyzing factors, that influence their decisions. Another objective is to give recommendations to the case company about how to reach right people in Russian organizations with their message. In the theoretical part of the study the main issues are related to the general principles of organizational buying behavior and main concepts of the topic. When conducting this research both Russian and English sources are used. The most related topics of the literature are  «Organizational Buying behavior »,  «Business-to-business marketing » and  «Industrial marketing », presented by Philip Kotler, Frederick E. We will write a custom essay sample on Organisational Buying Process or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Webster Jr. and Yoram Wind and Kovalev A. I Empirical part is based on a case study and describes the organizational buying process on example of 3 Russian companies, which were chosen according to the criteria of location, size and industry. The data for case study is gathered by conducting an interview with members of buying centers within these companies. Implementation of theory to the practice faced some difficulties such as misunderstanding of the topic and unwillingness of companies to provide full information. Business markets mostly concerns producer and reseller markets (Vitale et al, 2010, p. 131) Generally, business markets consist of fewer, but larger customers than consumer markets and are involved in purchases of significantly large value having complex economic, technical and financial considerations. Business markets also differ from consumer markets in such aspects as: sales volumes, marketing structure and demand, nature of products and most relevant for this thesis – types of decision and decision process (Ibid). Organization buying is the decision-making process by which formal organizations establish the need for purchased products and services and identify, evaluate, and choose among alternative brands and suppliers (Webster Wind, 1996). The nature of the buyer decision process in a business-tobusiness environment differs from the consumer ones, that is why understanding of organizational buying behavior is essential– it helps to develop the right approach to corporate clients and establish strong bonds between  «sellers » and  «buyers ». 4 1. 1 Background of the research Organizational buying behavior is an extensive concept as it depends on many factors. However, understanding the organizational buying process is a key prerequisite for the development of business marketing strategy. With knowledge of the customer firm’s decision making process and buying behavior, market managers are in a far better position to develop marketing strategies, build win-win relationship with customers and influence purchasing decisions successfully. The case company Holiday Club Resorts Oy is one of Europe’s largest vacation enterprises. The company’s specialization is holiday centers, spa hotels and time share apartments. Holiday Club operates both on consumer and business markets as their customers are different companies and organizations as well as representatives of public sector. This research is done to support the new project of the company – Saimaa Gardens large tourist and leisure time resort in Finland that will be opened in Autumn 2011. New holiday center will provide large facilities for conferences, business meetings and corporate parties (Holiday Club Oy 2010). While Finland and Russia are neighboring countries with well-developed connections in tourism area, Holiday Club’s officials are willing to attract Russian corporate clients. This thesis is a part of a bigger project, that consists of two studies. The first one is devoted to Russian outbound tourism and gives understanding of  «What organizational clients want?  », the second one answers the question  «How organizations buy?  ». The whole project is carried out by two students. Alena Tsyvinskaja is responsible for the first part, called  «Russian outbound MICE tourism – demand and concept », while this study is accomplished by Olga Loginova. The purpose of this study is to find out reasons and factors which affect the buying decisions and choice of leisure service provider. The research is aimed to analyze buying behavior process in Russian organizations and provide 5 possibilities for Saimaa Gardens to fulfill corporate requirements and reach their target market successfully. 1. 2 Research problem and objectives The main objective of this thesis is to give understanding of organizational buying process in Russian companies and provide recommendations to Saimaa Garden, how to reach right people with their message. For this purpose few Russian companies will be targeted as potential customers. Each organization has buying center – a group of people, who are responsible for buying decisions. (Webster Wind,1996). The research will be based on direct communication with these people in order to understand their roles and identify factors that affect their decisions. Main research problem consists of 3 parts: -find members of the buying center -analyze their roles and decision making process -describe an organizational buying process in general In the final outcome, Holiday Club will benefit from thesis in several ways. Firstly, this project will give an understanding of organizational buying behavior in Russian companies. Secondly it will provide a framework that will help to affect decision making process in a most efficient way. And finally, as research involves communication with companies, it will give a good opportunity to find first corporate customers. In general, possession of such knowledge will facilitate entering a new market for Holiday Club. 1. 3 Theoretical framework The theoretical framework of this thesis includes theories about nature of organizational buying in general and decision making process particularly. Theories, concerning organizational buying and decision making process gives an overall understanding of how organizational purchasing is executed, how 6 decisions are made and which factors influence them. Organizational buyers decision process model gives a clear guidelines how decision is made step by step. And Buying center’s analyses provide ideas for the practical part about how to recognize people, responsible for decision taking and to define roles and motives of those people. When conducting this research both Russian and English sources were used. The most related topics of the literature are  «Organizational Buying behavior  »,  «Business-to-business marketing » and  «Industrial marketing ». In theoretical part of the study information from Philip Kotler’s  «Marketing management »,  «A general model for understanding organizational buying behavior », written by Frederick E. Webster Jr. nd Yoram Wind and book of Russian author Kovalev A. I.  «Industrial Marketing » was used. The full list of sources provided at the end of the study. 1. 4 Research context 1. 4. 1 Business tourism As this study is devoted to business tourism, it is appropriate to give a small overview of this topic. In recent times more and more organizations have gone global, business connections have become international and economic activities are spread all over the world. As it’s commonly known, successful business is impossible without contacts, technologies and information exchanging, gaining new partners and customers. Due to the rapid growth of business contacts with foreign partners, business tourism is seen as an important niche market, and is one of the fastest growing sectors of the tourism industry. This segment of the tourism industry has also been referred to as Meetings, Incentives, Conventions and Exhibitions (MICE). The concept of MICE stands for corporate outbound tourism, aiming to bring people together for a particular entertaining or business purpose. (Business Travel Worldwide 2011. ) 7 In general, MICE encompasses the following activities: ? ? ? ? ? Meetings and conferences Exhibitions and trade fares Incentive travel Corporate events Outdoor events Individual corporate travel (Ibid) According to the statistics, provided by RBTA (Russian Business Travel Association,2010), in share correlation the structure of MICE travelling has the following form: 71% for individual travelling, 16% for participation in conferences and congresses, 11% for visiting exhibitions and approximately 2-3% for incentive travel. Business travelling may peruse different aims and according to  «Business Travel Worldwide » (2011) some of them are: ? ? ? ? ? Establishing partner relations, negotiating the contracts, concluding deals Visiting and taking part in the exhibitions Participating in congresses, conferences and seminars Trainings, professional development trips Incentive trips (trips, usually granted as a reward for employee’s outstanding performance) According to Business Tourism Partnership (2010) principal characteristics of business tourism include the following: †¢ it is at the high quality, high yield end of the tourism spectrum †¢ business tourism is year-round, peaking in Spring and Autumn but still with high levels of activity in the Summer and Winter months †¢ it is resilient, being much less affected by economic downturns or by disasters than leisure tourism and other sectors of the national economy 8 †¢ business tourism stimulates future inward investment as business people see the attractions of a destination while travelling on business or to attend a conference, exhibition or incentive, and then return to establish business operations there. According to Swarbrooke and Horner (2001), the participants of business tourism market can be divided into 3 groups: Consumers: Individuals Companies Associations Intermediaries: Travel Agencies Exhibition companies Event management companies and others Suppliers: Transport operators Accommodation operators Incentive travel venues Specialist services Figure 1 Participants of business tourism market. The figure represents the simplified scheme of business tourism market. In the reality the process might look different, including several intermediaries or ,vice versa, the link of intermediaries might be excluded as consumers are willing to arrange their business trips on their own. 1. 4. 2 MICE in Russia Although the thesis topic doesn’t cover business tourism market analysis, several words should be said about MICE market in Russia. Russia is a country where business tourism in general is actively developing now. However, the concept of MICE is still rather new for Russian companies. The reasons for this might be the insufficient development of corporate culture in general and small amount of international business contacts. Anyway, Russian corporate travel has not the same level as  «ancestors » of business tourism USA and European countries. 9 In general, MICE tourism in Russia can be characterized by following features (RBTA 2010): ? ? ? ? Outbound tourism is prevailing (most Russian companies prefer travel abroad rather than within the country) Problem such as lack of qualified agencies still exist. The demand for MICE services is fluctuating and not stable Incentive tourism is significantly less popular comparing with other parts of MICE 1. 4. 3 Case company profile Holiday Club Resorts Oy is one of Europe’s largest vacation ownership enterprises. It was established in 1986 and in the beginning it focused primarily on the vacation ownership business, purchasing hotels on the territory of Finland (Holiday Club Oy 2010) The company has been buying hotels and resorts as well as building their own holiday homes and spa centers. The growth of Holiday Club vacation ownership system continued and by 2007 Holiday Club expanded to Sweden (Ibib. ) By 2009, after several successful acquisitions Holiday Club becomes the leading vacation ownership enterprise in Europe. At 2010 a building of new resort – Saimaa Gardens was started (Ibid. ) In overall Holiday Club Resorts Oy owns holiday homes in 26 destinations in Finland, a holiday destination in Calahonda, Spain, as well as Holiday Club Are and Ekerum Golf and Resorts (Oland) holiday destinations in Sweden. Holiday Club’s 6 spa hotels in Finland have belonged to the S-Group’s subsidiary, Sokotel, since April 2006, and they operate under the name Holiday Club Spa Hotels. The chain comprises Holiday Club Caribia in Turku, Katinkulta in Vuokatti, Tropiikki in Kuusamo, Eden in Oulu, Saariselka and Tampere Spa (Holiday Club official web-site 2011. ) 10 1. 4. 4 Saimaa Gardens In this study the analysis is carried out from the standpoint of Saimaa gardens spa resort, as it is the nearest hotel of Holiday Club chain to Russia. Saimaa Gardens is a wellness resort, comprising spa hotel, holiday houses, various top-class apartments, golf centre, a great variety of shops, restaurants and galleries. It’s located at the shore of Lake Saimaa, nearby Imatra and occupies approximately 300 hectares of total area. Saimaa Gardens is also the nearest large tourist attraction to St. Petersburg in Finland. Companies’ clients belong both to consumer and business markets. Holiday club’s resorts provide services for public consumers as well as for corporate clients because they have good amenities for family vacation and honey moons along with facilities for conferences, corporate parties and business travelling. Holiday Club sees a great potential particularly in Russian tourists and organizations, as it will be situated near Saint-Petersburg, a city, where travelling to Finland is popular and easy. 1. 5 Limitations This thesis does not handle deep analyses of business tourism market and just gives a small overview of this topic to provide basic understanding of this tourism sphere. Consumer needs and preferences as well as product specifications are not covered by the study as this is a topic of a parallel research, prepared by another student. The theoretical part of this thesis is limited to theories about composition of the buying center and it’s characteristics, decision making process and factors, influencing it. The theories also describe the difference between organizational and consumer buying. These theories were chosen, because they are closely related to the research problem and they support the empirical part of the thesis by providing guidelines how the organizational buying process looks in real life. This thesis does not cover theories about sales techniques and relations between buyers and sellers, because one of the main objectives of bachelors’ thesis is to make the topic narrow but analyze it deeper. 11 2 RESEARCH METHODOLOGY AND IMPLEMENTATION The research was done according to a plan that consisted of 3 stages. The first stage involved analyzing of theoretical background and gave a comprehensive view on organizational buying behavior process, describing composition of buying center, identifying factors, influencing decision making process and exploring all stages of this process. After that the theory was ready to be implemented in life. On the second stage the search of companies that may be interviewees for the research and potential clients for Holiday Club was done. The search criteria was explained in empirical part. When organizations were identified, their portfolios should be created to obtain knowledge about potential customers. The final and most important stage of research was identifying the buying centers in chosen organizations and conducting an interview with it’s members. This was done to identify roles and motives of members, analyze the decision making process and finally develop an effective framework according to gained information. Figure 2 represents the plan research. Theory analyses Buying behavior -main concepts -influencing factors -buying center -decision making process Companies’ portfolio gathering What size? What industry? What location? Interview Figure 2. Research plan. 12 As it was stated above, the main research problems were: finding members of the buying center, analyzing their roles and decision making process and describing an organizational buying process in general. In order to understand, what the most effective methods for solving these problems are, a book of Tony Proctor (2005 p. 63)  «Essentials of Marketing research » was read. After examination of possible methodology, it was concluded that the most appropriate methods to solve thesis problems were qualitative research, case study and analyzing of primary and secondary data. 2. 1 Quantitative research Quantitative research produces numbers and figures, while qualitative research provides data on why people buy, what motivates them to buy, or their impressions of products, services or advertisements. It also produces information on behavior, attitudes and intentions. Simply put, qualitative research goes inside of people’s thinking, value system as well as decision making process, what fitted perfectly objectives of this study. This type of research involves different approaches such as focus groups, interviews, feedback analysis, surveys and others. It relies on primary data as well as on secondary. In this study the object of qualitative research was an organizational buying behavior (Proctor, 2005 p. 71. ) The research was carried out in a context of business tourism, which is very specific area of business market. That is why organization buying process in business tourism market is based on general model of organizational buying. So first of all, problem solutions required general knowledge about such concepts as buying center, organizational buying and others. That kind of information was necessary for good orientation in actual topic and for further planning of the research. To gain this information secondary data analysis was used. 13 2. 2 Secondary data analysis Secondary data analysis is the method of using preexisting data in a different way or to answer a different research question than that intended by those who collected the data (Schutt 1999). The sources of secondary data may be different: books, magazines, newspapers, internet, earlier conducted surveys, etc. The organizational buying behavior has been studied by many authors such as Philip Kotler, Frederick E. Webster Jr. , Yoram Wind, Ajay Kumar Kohli and others. Their books and articles were used as sources of theoretical information. Secondary analysis of different statistics was also conducted to help to choose the right kind of companies for the case study, which is described further. 2. 3 Primary data analysis and case study The study was accomplished for the particular organization, one of the needs of which was understanding of organizational buying process in Russian companies. Solving this problem required a primary data analyses. Primary data is data observed or collected directly from first-hand experience. There are many methods of collecting primary data: ? ? ? ? Questionnaire Interview Observation Case study, etc. (Proctor 2005, p74. ) This research is based on a case study. The purpose of case study is collecting information about organizational buying in Russian companies from the  «first hands ». The most appropriate method to collect it was interview. For that purpose 3 Russian companies were chosen. The amount of 3 went from the principle, that analyses of 1 company is definitely not enough, while 5 or more requires much more time. Moreover 3 companies represent 3 kinds of organizations: small, medium and large. In order to choose 3 respondents, it 14 was needed to find out what kind of companies normally buys the MICE trips and how they can be specified according to the industry, size, location, and etc. As Saimaa Gardens will be the nearest Finnish leisure attraction to the SaintPetersburg, it was quite obvious that case companies would be located in SaintPetersburg, Leningrad region and Vyborg. Another criteria, size of case companies, was based on assumption, that organizational buying process in small organizations differs from one in big corporation’s due to the amount of staff, availability of funds and corporate culture in general. The last aspect of the choice was the industry. There was no difference for Holiday Club Oy which kind of companies would use their services. So it was necessary to investigate what kind of companies buy MICE trips more often. According to the statistics for the year 2009-2010, provided by VIP-tour agency (contact person- Stanislav Lisovsky, sales manager), companies, represented 5 industries, used MICE services more frequently: ? ? ? ? ? Metal industry IT industry Oil and gas industry Estate industry Pharmaceutical and medicine industry According to this information a list of potential companies was created and proposals to take part in the interview were sent. Some companies didn’t respond at all, some provided unclear and poor information. However, it was possible to choose 3 companies, whose response was full and actual. That is how 3 case companies were chosen. Using the knowledge and information gathered for the theory, the research questionnaire was developed so that questions were straight, easy and aimed to minimize the uncertainties. Finally, despite of all difficulties, 3 interviews were carried out. Based on these interviews, it was possible to gain valuable and unique information, concerning compositions of buying centers and organizational buying processes in context of business tourism. 15 3 THE NATURE OF ORGANIZATIONAL BUYING 3. 1 Organizational vs. onsumer buying According to Webster and Wind (1995), organizational buying is the decisionmaking process by which organizations establish the need for purchased products and services and identify, evaluate, and choose among alternative brands and suppliers. It takes place i n the context of a formal organization influenced by a budget, cost and profit considerations. Consumer behavior has not much relevance for the industrial marketer. This is due to several important differences between the two purchase processes. Comparing complicity of buying processes, buying decisions are made relatively easily and quickly by individual customers, organizational buying involves thorough and deep analysis. This is because organizational buying usually involves many people in decision process with complex interactions among people and among individual and organizational goals. Furthermore, rganizational buyer’s decisions require more information, undergo longer evaluation and more uncertainty about product performance. Companies usually adopt certain methods for buying products and employ skilled professionals for purchasing departments. (Kotler 1997, p. 205. ) According to Sandhusen (2000 p. 248), when compared to demand patterns in consumer market, demand p atterns in industrial markets tend to be more concentrated, more direct, more dependent on other markets and purchases of related products and reciprocal agreements. Demand for goods in consumer markets is heavily affected by the changes in the prices so that it can be concluded that consumer market demand is price elastic. The organizational demand for products or services can be elastic only on early negotiation stage when many suppliers are actively competing on price for contracts. Once contracts are negotiated, however, demand becomes inelastic and is not influenced by short-run price changes. Frequently, demand for some b2b products is related to demand for other b2b products, what is called joint demand. For example, if Food Drink supplier for a hotel restaurant has delivery problems or poor service, it will probably cut back on its purchases of 16 foodstuffs. It’s also important to mention that demand for industrial products derives largely from demand for consumer goods. It’s quite typical or tourism market as purchasing travel package for the company’s purposes, organizational buyers sometimes follows consumer’s opinions and reputation on the consumer market. According to Kovalev (2003 p. 203), despite of ordinary consumers, industrial buyers are more likely to purc hase products directly from suppliers or manufacturers and in larger quantities, than consumers. Buying decisions of a consumer market is simple where it purely depends on the wish of consumer. But business buyers face complicated buying process where they have to adhere to purchasing standards, satisfy complex requirements and involve approval of many people. Consumer buying is generally short term focused where they conclude the relationship with seller upon the transaction is completed.

Sedimentation

Sedimentation SedimentationAbstractSedimentation is the process of separating a liquid mixture of suspended particles into clear supernatant liquid and denser slurry having a higher concentration of solids. This is usually accomplished by allowing the particles to settle through the force of gravity, mechanically using centrifugal force, or electrostatically using an electric current. Continuous sedimentation tanks are usually used in wastewater treatment facilities to separate suspended particles from wastewater.This experiment aims to determine the effect of initial concentration and initial height of the slurry on its settling characteristics. Using a set of data obtained from the experiment, a continuous thickener or clarifier must then be designed. The batch sedimentation experiment was accomplished by measuring the height of the clear liquid interface at two-minute intervals using initial concentrations of 25, 50, and 75 grams per liter and initial volumes (convertible to height) of 1000, 90 0, and 800 milliliters. Two trials were conducted for each matrix.Figure 1From the data, it was observed that as the initial concentration of slurry is increased, the initial settling velocities decrease. The initial height has no effect on the initial settling velocity but can affect the rate at which solids compact. However, it was found that how the height affects compaction can be unpredictable. For the design of a thickener using batch sedimentation data, the required area was calculated using the Coe and Clevenger, and the Talmadge and Fitch methods. The results were 1.3112 m2 and 2.2714 m2, respectively.During the course of the experiment, various problems were encountered that may have lead to slight errors. These problems were usually problems of measurement. Using masking tape can cause slight errors if not applied to the cylinder properly. There were slight difficulties during the initial stirring of the slurry because of the lack of long stirring rods. Furthermore,

Definition and Examples of Lexicogrammar

Definition and Examples of Lexicogrammar Lexicogrammar is a term used in systemic functional linguistics (SFL) to emphasize the interdependence ofand continuity betweenvocabulary (lexis) and syntax (grammar). The term lexicogrammar (literally, lexicon plus grammar) was introduced by linguist M.A.K. Halliday. Adjective: lexicogrammatical. Also, called lexical grammar. The advent of corpus linguistics, notes Michael Pearce, has made the identification of lexicogrammatical patterns much easier than it once was (Routledge Dictionary of English Language Studies, 2007). Examples and Observations Vocabulary and grammatical structures are interdependent; so much so that it is possible to say with some justification that words have their own grammar. This interdependency of lexis and grammar is evident everywhere in language. For example, lexical verbs have valency patterns: some verbs can be used with a direct object (I made some oven gloves), or with both a direct object and an indirect object (The government awarded them a pay rise), others need no object at all (The Colonel was laughing).  (Michael Pearce, The Routledge Dictionary of English Language Studies. Routledge, 2007)The heart of language is the abstract level of coding that is the lexicogrammar. (I see no reason why we should not retain the term grammar in this, its traditional sense; the purpose of introducing the more cumbersome term lexicogrammar is simply to make explicit the point that vocabulary is also a part of it, along with syntax and morphology).  (M.A.K. Halliday, Systemic Background, 1985. On Langu age and Linguistics. Continuum, 2003) [A]ccording to systemic functional theory, lexicogrammar is diversified into a metafunctional spectrum, extended in delicacy from grammar to lexis, and ordered into a series of ranked units.  (M.A.K. Halliday, Hallidays Introduction to Functional Grammar, 4th ed., revised by Christian M.I.M. Matthiessen. Routledge, 2013)[L]exico-grammar is now very fashionable, but it does not integrate the two types of pattern as its name might suggestit is fundamentally grammar with a certain amount of attention to lexical patterns within the grammatical frameworks; it is not in any sense an attempt to build together a grammar and lexis on an equal basis...Lexico-grammar is still firmly a kind of grammar, laced, or perhaps spiked with some lexis. (John Sinclair, Trust the Text: Language, Corpus and Discourse, edited with Ronald Carter. Routledge, 2004) Lexicogrammar and Semantics Just as lexis and grammar are considered to form a single stratum, Halliday considers that the lexicogrammar is not a separate system or module apart from semantics, but is rather an underlying component of the meaning-making system of a language. The stratum of semantics is thus not thought of as an abstract or logical structure, but rather as the medium through which humans use language to interact in their social and cultural context. A consequence of this is that the language, and in particular the lexicogrammar, is structured by the expressive and communicative functions it has evolved to convey.   (Christopher Gledhill, A Lexicogrammar Approach to Checking Quality: Looking at One or Two Cases of Comparative Translation. Perspectives on Translation Quality, ed. by Ilse Depraetere. Walter de Gruyter, 2011) Lexicogrammar and Corpus Linguistics Generalizations on the structure of language tell us little about how people actually use the language, and consequently how a language really is. The patterns of structural and lexical behaviour are not revealed by the linguists introspection or from a few examples chosen to fit the pattern. This is the conclusion that increasingly is being drawn from a growing body of linguistic research on large computer corpora or databases. It is only when we come to investigate a language from samples of millions of words of running text that we can really begin to understand how words and structures behave and interact...A theory of language or a model of a particular language . . . has to account for use as attested by corpus linguistic research. If such a theory purports to give rise to language description, it must have the potential to incorporate the vagaries and idiosyncrasies of lexicogrammatical behaviour and the cryptotypical phenomena which are uncovered by the observation of languag e use on a significantly larger scale.  (Gordon H. Tucker, The Lexicogrammar of Adjectives: A Systemic Functional Approach to Lexis. Continuum, 1998) Alternate Spellings: lexico-grammar
