utility theory for decision making ppt

200) + 0.3 (Rs. Its major defect is that, as one number, the discount rate is used to combine the effects of both risk and the time value of money. Therefore, by using the maximiza­tion of expected utility criterion, the rational en­trepreneur would decide against the project. The model, it may be recalled, states that the value of a firm to its investors is the discounted present worth of future profits or income. To answer this question we have to find out the EMV of such a gamble which is: Here EMV is the sum of an infinite arithmetic series of 1’s. Mr. X’s EMV from playing this gamble is Rs. If any T- shirt remains unsold during summer, it can be dis­posed off at half the price in winter. Hence, it involves more risk. The proof of this is known as the fundamental theorem of game theory. The re­maining entries in the regret matrix are computed by following the same procedure, i.e., by compar­ing the optimal decision with the other possibili­ties. We illustrate the concept in table 8.6 below: If we adopt the simple EMV criterion, a cursory glance would make project B apparently seem to be the best possible choice. The change in the risk level because of the decision taken by the firm will have a direct bearing on its NPV level. Since EMV is the same under two alternative actions the decision-maker would re­main indifferent between them. The two competitors may not have the same approximate utilities (with a negative sign). Some Useful Examples: Example 1: Decision-making of a Local Public Official: Grant programmes from the central government to local governments; suppose that a public official is in charge of the police budget, which is paid for by local taxes. Table 8.5 lists the respective probabilities for each of the events and the associated expected values. He has implicitly assigned a probability of occurrence of 0.25 to the maximum payoff and of 0.75 to the minimum pay­off. Risk can be characterized as a state in which the decision-maker has only imperfect knowledge and incomplete information but is still able to assign probability estimates to the possible outcomes of a decision. The Laplace criterion of insufficient reason dif­fers from the minimax regret criterion in that it in­volves the use of probabilities, that is, if we are uncertain as to which event will occur, we can as­sume (correctly or incorrectly) that all states (lev­els of demand) are equally likely and then assign the same probability to each of the events, i.e., we assume that each event is equi-probable. The manufacturer of these has imposed a condition on you: You have to order in batches of 100. Therefore they would decide not to participate in this type of gamble characterized by highly uncer­tain outcome against an unlimited payment (that has to be made if the gamble is accepted). In other words, by assigning subjective probabilities to decision problems, deci­sion-making under uncertainty can easily be con­verted into risk analysis. Thus diminishing marginal utility of money leads di­rectly to risk aversion. 500, whereas project B has an EMV of Rs. The concept may now be illustrated. Since it has the highest payoff the decision-maker would choose A4. When oppo­nents are involved, the opponents’ strategies can be represented by the columns. In some cases, however, a relative frequency (also known as the classical) interpretation of probability does not work because repeated trials are not possible. 300), then his risk premium (RP) can be defined as: In such a situation Mr. Hari is willing to pay Rs. This criterion suggests that after a decision has been made and the outcome has been noted, the decision-maker may experience regret because by now he knows what event occurred and possibly wishes that he had selected a better alternative. It is quite obvious that the larg­est entry in every column will have zero regret. 500, he would be described as risk- neutral (indifferent). This particular observation has important impli­cations for project planning and long-term invest­ment decision. 500. Rough early versions: Sandholm, T. and Lesser, V. 1994. 7. The implication is simple: as his wealth increases, the individual receives less and less ex­tra utility (satisfaction) from each extra rupee that he receives. Here the de­cision-maker considers both the maximum and the minimum payoffs from each action and weighs these extreme outcomes in accordance with subjec­tive evaluations of either optimism or pessimism. These estimates may be sub­jective judgments, or they may be derived mathe­matically from a probability distribution. We do not ask clients to reference us in the papers we write for them. There are also significant efforts aimed at applying algorithmic advances to applied problems in a range of areas, … 350) + 0.3(Rs. 10 per shirt, if 200 or more are ordered, the cost is Rs. 16,000 x .20 + (Rs. 100,000 and a S.D. Risk is objective but uncertainty is subjective; risk can be measured or quantified but uncertainty cannot be. 6,000. Most parlour games are of this type. In fact, it is easier to compre­hend ‘trees’ easily than tables when we move to more realistic business situations involving various decisions (branches). Here the utility function shows constant margi­nal utility of money. The most obvious defect of the CE approach, outlined above, is that it requires the specification of a util­ity function so that risk premium can be numerical­ly measured or quantified. As a general rule the value of following a par­ticular action can be determined according to the following index: The decision-maker would then pick that op­tion which yielded the maximum Hi value. For example, farmers face considerable uncer­tainty about the price they will receive in October for a crop planted in July. With complete conflict of interest the game is a zero-sum game. The price of tea next week may also be random owing to unfore­seen shifts in supply and demand. 325,410 would far exceed the profit of any one of the two. Here we use the three terms ‘wealth’, ‘money’ and ‘return’ synonymously. Such risk aversion is re­flected in the valuation model used by investors to determine the worth of a firm. 3197.3 for project B. Firstly, in a large organiza­tion, whose utility function has to be used remains an open question. 5,000 supported by a 50% chance of winning Rs. 300 and if demand were 200 units, he would order 200 and the payoff would be Rs. 125. – 4,000) x .80. 8.6 summaries mathematically Mr. X’s decision, i.e., not to take the coin flipping bet, in two differ­ent ways. To a rational decision-maker, the value of infor­mation can be treated as the difference between what the payoff would be with the information currently available and the payoff that would be earned if he were to know with certainty the out­come prior to arriving at a decision. The results of employing the six criteria to our T-shirt example are given in Table 8.3. 8.2 we show the likelihood of a particular price on a given day by the height of the bell-shaped curve. The player is supposed to receive or win 2n rupees as soon as the first head appears on the n-th toss. Instead, we’ll continue to invest in and grow O’Reilly online learning, supporting the 5,000 companies and 2.5 million people who count on our experts to help them stay ahead in all facets of business and technology.. Come join them and learn what they already know. Alternative courses of action (strategies). Since there are con­stant changes in market conditions and in the num­ber (range) of competitive (rival) products, it is not possible to repeat the experiment under the same conditions hundreds of times. There are two ways of adjusting the model in the light of reality, i.e.,: (1) Using the con­cept of certainty equivalent and. Now we have a random price for the firm’s out­put. Thus we can say that a payoff matrix provides the decision-maker with quantitative measures of the payoff for each possible consequence and for each alternative under consideration. The results of such computations are presented in Table 8.10 below: It is clear that construction of the prototype us­ing conventional materials (A1) is the least risky alternative. Since his CE is less than his EMV, the risk pre­mium is positive and he would be classified as a risk-averter. Therefore, an indi­vidual’s attitude toward risk is directly reflected in the CE adjustment factor. 8.8 presents the decision tree associated both the problem faced by Mr. Ram. Certainty Equivalents. It is obvious that CE sum equal to the EMV im­plies risk indifference. We are a custom essay writing service that's open 24/7. He is con­sidering whether or not to make long-term invest­ment for introducing the product in the market. For their own survival, however, decision-­makers commonly choose a course of action that is supposed to provide a satisfactory return subject to the acceptance of a certain degree (level) of risk. Thus the optimal decision would be to accept the project, i.e., invest in the product. Uncertainty does not seem to suggest that the decision-maker does not have any knowledge. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. In case of two or more projects (alternatives) having unequal costs or benefits (payoffs) the CV is undoubtedly a preferable measure of relative risk. Thus, this criterion suggests that the decision-­maker should attempt to minimize his maximum regret. Now, in the context of our NPV model we may assert that risk aversion is reflected in the fact that any decision that a firm makes will sure­ly change its risk level — the degree of risk to which it is exposed. If we adopt the clas­sical definition of probability as the limit of rela­tive frequency, we know one thing at least. In the past 40 decades, there have been many innovations in the development of low … 174 Likes, 12 Comments - KatherineAnn (@rin_in_nature) on Instagram: “ESF class of 2020 I just graduated from SUNY College of Environmental Science and Forestry with a…” Therefore, in our example, the expected value of perfect information is to be computed as follows: EMV under conditions of certainty = Rs. Even with situations involving antagonistic decision makers, this analysis is often not applicable under perfect competition. The first method of dealing with risk it to re­place the expected net income figures (Rt — Ct) in the NPV equation with their certainty equival­ents. 200; if demand were going to be 150 units, he would place order for 200 units with a payoff of Rs. 390 and Rs. Likewise, a CE sum greater than the EMV indicates risk. All we have to do is to subtract each entry in the payoff matrix from the largest entry in its column. The market­ing manager also feels that there is a goodwill loss of 50 paise for each T-shirt that consumers want to purchase from your shop but cannot because of inad­equate supplies. Compare your choice under each criteria. Regret is defined as the difference between the ac­tual payoff and the expected pay-off, i.e., the pay­off that would have been received if the decision maker had known what event was going to occur. Decision-Making Environment under Uncertainty 3. Therefore, following the Laplace criterion, the decision-maker would order 200 units because it has the highest expected value. It is clear that there is no perfect convergence of decisions, al­though A2 is dominant. Here the slope of the utility function is increas­ing as the individual’s wealth increases. But its payoff is also the lowest of the three. He estimates that the probabilities associated with each of these out­comes are 0.25, 0.50 and 0.25, respectively. 150,000+ Rs. However, there is hardly any justification for the assumption of a compounding risk factor, rather than a risk difference of just three percentage points (1.13 – 1.10) or a ratio of (1.63 – 1.46=) 1.116 by the end of four years. The classic example, known as the … Recall that the CE approach to adjusting our basic valuation model to risk operated on the numerator (Rt — Ct). Instead, the an­alyst makes a more critical appraisal before as­signing subjective probabilities to each event. His risk reference can be meas­ured by the nature of his utility function. If this factor is brought into consideration, future cash flows for each project are discounted at a rate, K*, which is based on the risk associated with the pro­ject. Now an impor­tant question is: how to adjust our basic valuation model for risk? The optimal decision would still be the same, viz., ordering 200 units; thus the manager’s decision is not very much sensitive to changes in the proba­bility assignments. To pay more for perfect information than the loss that would result because of a lack of this information (uncer­tainty) would be irrational. If the future event that will occur could be pre­dicted with certainty, the decision-maker would merely look down the column and select the opti­mal decision. This simply explains why a decision maker who passes decisions solely on expected val­ue is likely to make choices that are inconsistent with his psychological preferences for risk taking. (Try to guess why.) Thus, the project B has a higher EMV but it is risker since it has a higher standard deviation. To illustrate, a discount rate of 10% becomes a discount factor of 1.46 [= (1.10)4] by the end of four years, and the 13% rate becomes 1.63 [=(1.13)4]. If head appears, Mr. Hari will get Rs. Other versions of consequentialism may be generated by making small changes in this theory, as we shall see, so long as the new theory stays faithful to the broad idea that morality is all about producing the right kinds of overall consequences. We may now summarize the basic characteris­tics of the decision problem in the following pay­off matrix. 4,000. 300 (CE = Rs. From this emerges the diminishing marginal utility hypothesis. Fig. Thus if we go by the EMV criterion we can assert that the gambler (player in our example) will be ready to wager everything he owns in return for the chance to receive 2n rupees. (Samuel C. Certo, 2003) Decision making can be defined as a process of choosing between alternatives to achieve a goal. He would decide not to invest in the new product. But there is a difference between the two concepts. In short, the decision-maker’s attitude toward risk determines the shape of his utility function and assists the choice of alternative in a decision problem involving risk.

Scholar Assignments are your one stop shop for all your assignment help needs.We include a team of writers who are highly experienced and thoroughly vetted to ensure both their expertise and professional behavior. This assumes strategic signifi­cance both in reducing the anxiety surrounding the decision and in measuring the need for additional information. This criterion is also based on the assignment of probabilities. These not only constitute a formal description of the problem but also provide the structure necessary for a solution: 2. Utility-Based Termination of Anytime Algorithms. It is estimated that the cost of producing and marketing a batch of the product will be Rs. Laplace criteria. In the following payoff matrix of a decision problem show that strategy A will be chosen by the Bayes’ criterion, strategy B by the maximin criteri­on, C by the Hurwicz α (for α < 1/2) and D by the minimax regret criterion: Consider a hypothetical 4 x 6 payoff matrix representing a maximizing problem of decision-­maker, faced with total uncertainty. If profit maximization does not appear to be a sensible goal, one has to search out or identify another objective function for the firm. Such things often happen in reality and managers have to face such uncertain situa­tions. Additionally, the new computer chip would gen­erate additional profits of Rs. Recall that the expected value is a weighted average of the possi­ble outcomes, where the weights are the objective probabilities of possible outcomes. Computer Vision Group Work in Artificial Intelligence in the EECS department at Berkeley involves foundational research in core areas of knowledge representation, reasoning, learning, planning, decision-making, vision, robotics, speech and language processing. Yet the computation of its value is extremely useful to a manager. It is because the total cost is Rs. 150) + 0.2 (Rs. Decision making is the process of choosing the best alternative for reaching objectives. The public health community has tried for decades to show, through evidence-based research, that safe water, sanitation, and hygiene (WASH) and clean cooking fuels that reduce household air pollution are essential to safeguard health and save lives in low-income and middle-income countries. Therefore, by using the maximization of expected value criterion, the inventory manager would choose A2, i.e., order 200 units. In reality we observe that as an individual’s stock of wealth (money) increases, every addition­al unit of wealth gives him gradually less and less extra satisfaction (utility). In such a situation some criterion has to be tried to arrive at a relative measure of risk. By assigning subjective probabilities, the decision maker is, in essence, converting an uncertain situa­tion into a situation of risk. By contrast, uncertainty implies that the prob­abilities of various outcomes are unknown and can­not be estimated. Positive payoff implies profit and negative pay-off implies loss. On the contrary, if the product is not initially successful and there is total failure of the market­ing effort, the maximum amount of loss the entre­preneur has to incur will be Rs. Since profit is total revenue (= price x quantity) less total cost of producing the required quantity, profit is also a function of the random price. The decision-maker thus attaches his best estimate of the ‘true’ probability to each possible outcome. This theory can explain the increased and sustained neuronal responses observed in a highly predictable context [126,128,129,133]. 8.50. However, since the decision-maker does not have any knowledge about which event (state of nature) will occur or what is the chance of a particular event occurring, he is faced with a sit­uation of total uncertainty. Thus, the criterion is conservative in nature and is well-suited to firms whose very survival is at stake because of losses. To compute the EMV under conditions of certainty, we start with the assumption that the decision-maker se­lected the option with the highest payoff for each of the alternatives. Had his CE exactly equalled the EMV of Rs. 400,000 and Mr. Ram has been given six months time to complete the project. We devoted ourselves to developing a broad understanding of the economic aspects of the NPV equation. 5,000; if a tail appears, Mr. Y will pay Mr. X Rs. It is left as an exercise to the reader to demon­strate that the expected utilities of both the deci­sions: ‘investment in the product’ and ‘do not invest’ are zero. A new technique of decision making under risk consists of using tree diagrams or decision trees. The results of our calculations are shown in Table 8.7. Ranked data are then often used. The first one is deductive and it goes by the name a priori meas­urement; the second one is based on statistical anal­ysis of data and is called a posteriori. The basic point to note here is that they provide the decision-maker with a procedure for evaluating the benefits of obtaining additional information and comparing them with the costs of this information. Slicing, dicing and cross applications reporting and complex data analysis. 5,000 is greater than the increase in utility from winning Rs. The present complexity effect observed for super-deviants may thus indicate that responses to completely unexpected events were modulated by the degree of predictability of the pattern, which itself depends upon the … But what we do not know as yet is; how much would Mr. Hari be willing to sell his ticket for? 16,000) x .20 + U(Rs. The R&D engineers have succeeded in identifying two approaches, one utilizing conventional materials and another using a newly developed chip. So the maximization of EMV criterion is not a reliable guide in predicting the strategic action or strategic choice of an individual in a given decision environment. Given sufficient time and money, either of the two methods could be developed to specifications. To put the question in a different language, what is the lowest offer that Mr. Hari is willing to accept — Rs. So far we have considered only a single decision maker. Economics, Microeconomics, Managerial Decision-Making Environment. -4000) x .80. The three alternative strategies are to order 100 shirts (A1), 200 (A2) or 300 (A3). Hence Mr. Ram is faced with a perplexing dilemma — a trade-off between risk and profita­bility. However, in real life most people prefer to play safe and avoid risk. In truth, the less dispersed the probability distribution of possi­ble outcomes, the smaller the degree of risk of any given decision. One major drawback in the use of the EMV, EOL or EVPI is the method used to assign probabilities to the events. In this case, the six possible outcomes are equally likely (i.e., each one is an equi-probable event.). 8.4, the expected utility of the decision to ‘Invest in the Product’ is: E(U1) = U(Rs. 167.50, Rs. On the basis of differences in attitude toward risk, decision-makers are classified into three cat­egories: risk-averter, risk-indifferent and risk- lover. 8.6 who has an income of Rs. 504.50, it would be difficult for the decision-maker to measure the degree of risk asso­ciated with each action and thus arrive at a clear- cut decision. So according to our criterion, alternative A would be treated as less risky than alternative B. However, the assumption that each event is equi-probable is not made. Some Characteristics of a Decision Problem: All business decision problems have certain common characteristics. Now the values that a random variable can assume may not be equally likely (i.e., equi-probable events). However, one way pos­sible of overcoming this problem is to go through an alternative and better known risk adjustment pro­cess — the risk adjusted discount rate method. A decision tree is used for sequential decision-making. Strong critical thinking— making well-reasoned judgments about what to believe and what to do—is essential to consistently successful decision making. Fig. In such a situation, we cannot compare the two projects so easily by using the standard deviation measure. 8.5. So if B chooses B1, A chooses A1 and so on. For the T-shirts inventory and ordering problem, the payoff matrix is presented in Table 8.1. For example, if 100 T-shirts are ordered and demand is 150 units, then regret is Rs. In such a situation, taking the action with the highest EMV will surely lead to decisions that are quite in accord with the true preferences of the decision-maker. It is largely because of these two characteristics that the decision-making in an un­certain environment involves more subjective judgment. The two decision-makers will not choose their strategies independently. If you continue browsing the site, you agree to the use of cookies on this website. Suppose, that project A has an EMV of Rs. It can sell as much as it likes at the prevailing market price. Share Your PPT File, Steps Involved in Managerial Decision-Making. If, for instance, we assume that the decision-maker has a coefficient of 0.25 for a particular set of ac­tions, the implication is clear. B will choose strategy B3. The end result of the project involves the con­struction of a functional prototype. The expected monetary value (EMV) criterion no doubt furnishes necessary and useful information to the decision-maker. 16,000 will result. Instead, he suggest­ed that they responded to the utility that the prizes might produce. By putting the values of cash flow (X), expected value (EMV), and assigned probability from Table 8.6 into equation (8.13) we are in a position to quantify this risk. To compute the expected value of perfect information, we simply apply the same probabilities that were used in the EMV computations to these certain pay­offs: = 0.5 (Rs. 160,000 which is much less than the budgetary limit of Rs. If this happens, such a value is called a saddle point. For example, if the inventory manager knew, before arriving at the decision, that actual demand were going to be 100 units, the optimal decision would be to order 100 units with a payoff of Rs. Since NPV analysis uses a compounding factor in the denominator (1+r)t the incorporation of a risk adjustment factor in the denominator to deflate future values, heightens this compounding. The EMV of the decision to ‘invest in the prod­uct’ is: EMV1 = Rs. 8.7 presents the same information using decision trees. The cash offer he would accept in order to be induced to part with his ticket is the certainty equivalent (CE) of the lottery. Now we shall inter­pret our valuation model of the firm in terms of the expected utility approach. 30 (Rs. However, the important point to note is that the use of subjective probabilities has dimi­nished the significance of the distinction between risk and uncertainty. Now by using equation (15) we can calculate expected utility, based on the utility function of Fig. Ensuring that employees understand the decision-making process, giving employees a voice in the process, making unbiased decisions, and being consistent in the application of rules all lend to a procedurally just process. 200 risk premium to quit (sell the lottery tick­et). Moreover, decision trees highlight the sequential nature of decision-­making. For the roll of a die, the probability distribution is as follows: Here we let X denote the number on the face of the die and P(X) represents the probability of that out­come. Suppose, our inventory manager had obtained a different set of probability estimates for the three levels of T-shirt demand — that is, the probabili­ties are 0.2 for 100, 0.3 for 150 and 0.5 for 200 T- shirts.
