In sum, expected utility over final wealth states predicts equal preference between insurance against a small-stakes loss and a fixed payment in its expected value. 17.7. Expected value is the probability-weighted average of a mathematical outcome. Demand for Assets (a) Demand for Stocks (b) Demand for Insurance 1 Probability Theory and Expected. For example, if someone prefers dark chocolate to milk chocolate, they are said to derive more utility from dark chocolate. 0000010227 00000 n 0000018306 00000 n In this paper, the mean-value-distortion pricing principle is presented under anticipated utility theory as an approach to insurance premium calculations. x�b```f``�``g`��`d@ A�;G��F� k;@�j3�TO1y@V�A�0�Q��&!еGT�%�%D�S��]��#gk̨�ױ��vU�������]t�r�u��n�VSޟV1�hNkga3�Q����SQ���A�KF��X&g6��3�n.

Now the expected utility from the new risky job is less than the utility of 55 from the present job with an assured income of Rs. 3.3 Proof of expected utility property Proposition. Humans all bet with their lives either that God exists or that he does not. There are two acts available to me: taking my umbrella, andleaving it at home. This contract must be entered into before the outcome is known, that is, before the uncertainty is resolved.

For example, consider a person who is offered two jobs. Marginal Utility Bernoulli argued that people should be maximizing expected utility not expected value u( x) is the expected utility of an amount Moreover, marginal utility should be decreasing The value of an additional dollar gets lower the more money you have For example u($0) = 0 u($499,999) = 10 u($1,000,000) = 16 Expected Utility 4. While not necessary, it is convenient to assume that X is –nite. The decision maker will pay an amount greater than the expected loss for insurance. 2. Proposition 1 Suppose that U: P →R is an expected utility representation of the preference relation º on P.ThenV: P →R is an expected utility … Expected Utility Model The expected utility model dates back to the 18th century with the work of Daniel Bernoulli on the utility function and the measurement of risk. 0:5 p 50 + 0:5 p 50 = 0:5 7:1 + 0:5 7:1 = 7:1 So with square root utility, the consumer prefers to fully insure at actuarially fair prices. 0000005021 00000 n If Paul wants the best payoff in the long run and must buy 1 of the 2 insurance plans, he should purchase the? Suppose, for example, that Bart Dart owns a small business. (Expected utility theory) Suppose that the rational preference relation % on the space of lotteries $ satisﬁes the continuity and independence axioms. insurance company cannot tell the two apart, so they o⁄er fair insurance based on either (i) the average probability (0.4), or (ii) only Skippy™s probability (the highest risk person) (a) Find Myrtle™s expected utility of the trip with no insurance. 0000007551 00000 n X be a set of ﬁprizesﬂ. The theory recommends which option a rational individual should choose in a complex situation, based on his tolerance for risk and personal preferences.. 0000016617 00000 n 1.1 Expected Utility: Setup Let; 1. Lecture: Uncertainty, Expected Utility Theory and the Market for Risk David Autor 14.03 Fall 2004 1 Risk Aversion and Insurance: Introduction • A huge hole in our theory so far is that we have only modeled choices that are devoid of uncertainty. 1 Uncertainty and Insurance Reading: Some fundamental basics are in Varians intermediate micro textbook (Chapter 12). 0000017410 00000 n than the expected loss of utility without insurance, Vo -V2• Because of the way that the theory is specified mathematically, it appears as if the choice is between certainty and uncertainty of actuarially equivalent losses. By the substitutability axiom, the consumer will be indiﬀerent between … 0000045458 00000 n For example, a, shown by the dashed lines on the figure, the utility of $5000 is found by drawing first a vertical line from $5000 to intersect the curve and then a horizontal line from the intersection point to the utility scale, where 0.62 is found ‘as the utility of $5000. It requires preferences to exhibit two additional axioms of continuity and independence, which are somewhat controversial. The theory recommends which option a rational individual should choose in a complex situation, based on his tolerance for risk and personal preferences.. Each additional component decision process is predicted to compound the effect of preference for insurance. Under the simplest form, conventional expected utility theory assumes that a consumer's utility, U, is a function of disposable income, Y. The theory’s main concern is the representation of individual attitudes toward risk. • Expected utility allows people to compare gambles • Given two gambles, we assume people prefer the situation that generates the greatest expected utility – People maximize expected utility 18 Example • Job A: certain income of $50K • Job B: 50% chance of $10K and 50% chance of $90K • Expected income is the same ($50K) but in one case, 3. vNM expected utility theory a) Intuition [L4] b) Axiomatic foundations [DD3] 4. 0000006672 00000 n Expected utility is also used to evaluating situations without immediate payback, such as an insurance. 0000086494 00000 n Graphically (figure 7.4), if the utilit y function is concave, i.e., the individual is risk averse, then the utility 0000017695 00000 n 0000020471 00000 n 0000076160 00000 n H�T��n�0��S�`��J)���!mUh�`�T�e���{I� }�x�;˲�-���S����^6�q��Ʈ�����b�ɾ�P)`��b�frَ�$�ڊӬW8���|������ݠ�e�2���?Ţ�(gp!M���aٵR�Հ���rU�eo�elpR�@]�!q��M͇�)�l���6�=V����C�_RK��0 j�2KQ`)r�H�2�,�>' 0000034246 00000 n In other words, it is a calculation for how much someone desires something, and it is relative.

Secant Utility of welath. 0000004344 00000 n Thus, contrary to the expected utility theory (which models the decision that perfectly rational agents would make), prospect theory aims to describe the actual behavior of people. 15,000 [E(x) = 0.5 x 0 + 0.5 x 30,000 = 15000], Note again that Figure 17.3 we are considering the choice of a risk averse individual for whom marginal utility of money declines as he has more of it. 15,000 (Note that in the risky job also, expected income is Rs. Job A offers higher pay, but there's a 50 percent chance he'll have to move to an undesirable location; … $500 from insurance is the expected marginal utility that the additional $400 ($500 minus the $100 premium) brings. startxref (f) He’s willing to pay a maximum of $39 for full insurance, and his expected loss is $60. The extension of these insurance results beyond expected-utility models is not just a theoretical whim. expected utility theory and Yaari’ dual theory are special cases of anticipated utility theory (Puppe, 1991). 2. 0000002679 00000 n Which, once again, you shouldn't use these videos as insurance advice. Assuming a health insurance context, there is a probability, x, that the consumer will become 0000047941 00000 n The most important insight of the theory is that the expected value of the dollar outcomes may provide a ranking of choices different from those given by expected utility. With money income of Rs. Which of these acts should I choose? Example of a Utility of Wealth Function. Her marginal cost is the expected marginal utility that the $100 premium costs. 0000077723 00000 n The expected utility hypothesis is a popular concept in economics, game theory and decision theory that serves as a reference guide for judging decisions involving uncertainty. 0000066257 00000 n Pascal’s wager is also an example of using expected value to think about the world. ‘ After a utility curve has been drawn, utilities replace dollars and EUV re expected utility associated with not buying insurance. 0000048170 00000 n Insurance can increase this expected utility. A utility function is a representation to define individual preferences for goods or services beyond the explicit monetary value of those goods or services. The extension of these insurance results beyond expected-utility models is not just a theoretical whim. 0000017540 00000 n Maximizing the Expected Utility of Reinsurance Solution Overview Insurance companies carry reinsurance policies to transfer the loss potential associated with underwritten policies to alternative institutions. 0000004861 00000 n the insurance will decrease his expected utility, so he will refuse to buy the insurance. So far, probabilities are objective. 0000013835 00000 n Let’s see some of the alternative approaches that where formulated after the original expected utility theory came out. • Always a moderate amount of consumption for sure is better than a 50–50 chance of having a lot or nothing.

The utility-theoretic way of thinking about it Insurance companies use this to determine how much to charge you for your premiums. 0000051697 00000 n The expected utility theory then says if the axioms provided by von Neumann-Morgenstern are satisfied, then the individuals behave as if they were trying to maximize the expected utility. Suppose I am planning a long walk, and need to decide whetherto bring my umbrella. 0000014871 00000 n Probability Theory and Expected Value 2. This informal problem description can be recast, slightly moreformally, in terms of three sorts of entities. 0000011861 00000 n 0000000016 00000 n Today’s insurance companies are forced to sift through hundreds of thousands of claims to determine which qualify for reinsurance. Risk aversion coefficients and portfolio choice [DD5,L4] 5. Casualty Actuarial Society . . insurance company cannot tell the two apart, so they o⁄er fair insurance based on either (i) the average probability (0.4), or (ii) only Skippy™s probability (the highest risk person) (a) Find Myrtle™s expected utility of the trip with no insurance. 0000019470 00000 n Conventional Expected Utility Theory and Prospect Theory 2.1 Conventional expected utility theory. But still some people buy the private insurance. I Calculate Expected Utility without insurance 3b Insurance Example High Type I from ECON 201 at National Taiwan University Expected utility theory holds that the demand for insurance can be translated as a demand for certainty. 0000084191 00000 n Therefore, the expected value for n tosses would be: If we use the expected value as the decision criterion, the player should be willing to pay $∞ in order to play. Individuals will prefer to buy insurance in order to assure a certain amount of money (or to have a guarantee of lower losses), instead of its actuarial equivalent uncertain one. endstream endobj 86 0 obj<> endobj 87 0 obj<> endobj 88 0 obj<>/Font<>/ProcSet[/PDF/Text]/ExtGState<>>> endobj 89 0 obj<> endobj 90 0 obj<> endobj 91 0 obj<> endobj 92 0 obj<> endobj 93 0 obj<> endobj 94 0 obj<> endobj 95 0 obj<> endobj 96 0 obj<> endobj 97 0 obj<> endobj 98 0 obj<> endobj 99 0 obj<> endobj 100 0 obj<>stream 30 thousands, his utility is 75 and with his lower income of 10 thousands his utility is 45. They add up everyone in your ... (or concave utility functions, for the mathematically inclined). • Always having two slices is better than having four and sometimes having zero. Expected utility, in decision theory, the expected value of an action to an agent, calculated by multiplying the value to the agent of each possible outcome of the action by the probability of that outcome occurring and then summing those numbers.The concept of expected utility is used to elucidate decisions made under conditions of risk. Example 3 A decision maker’s utility of wealth function is given by u(w) = w −0.01w2, w < 50. Expected utility is a weighted average; to calculate it, multiply the utility of each possible outcome by the probability of that outcome actually taking place. 0000045181 00000 n •Diminishing marginal utility means that the fourth slice of pizza is less important than the first. The contract stipulates actions to be performed by one party or the other [1] immediately, before the resolution of the uncertainty, and [2] after resolution of the uncertainty, in each conceivable outcome, that is, in each contingency. This kind of premium calculation can be found in Denuit et al. Insurance. First, there areoutcomes—object… Expected utility theory is a special instance of the theory of choice under objective and subjective uncertainty. In other words, it is a calculation for how much someone desires something, and it is relative. 0000002946 00000 n 0000094840 00000 n <<67994371B5B61C419DF52D94AD38B336>]>> In expected utility theory under objective uncertainty, or risk, the probabilities are a primitive concept representing the objective uncertainty. • That’s convenient, but not particularly plausible. The concept of expected utility is best illustrated byexample. The expected value from paying for insurance would be to lose out monetarily. 0000005481 00000 n Pascal’s wager is also an example of using expected value to think about the world. We start with the von Neumann-Morgenstern expected utility model, which is the workhorse of modern economics. Suppose that, from any initial wealth level, a person turns down gambles where she loses $100 or gains $110, each with 50% probability. 0000064099 00000 n 0000001816 00000 n 0000009579 00000 n Expected Utility and Insurance in a Two State Model 1 Expected Utility 1.1 The Basics Expected Utility (EU) theory is a technique developed by Von Neumann and Morgenstern (1944) to deal with situations of quantiﬁable risk. 1, 2001, pp. For example, suppose: 0000025846 00000 n We characterize optimal indemnity functions both with and without the customary ex ante no … Then % admits a utility representation of the expected utility form. $8,700. 0000037802 00000 n 0 �` �bBd H�T�OO�@��|�9����4i8k�m,z��PId�,��o/����fvv�c�/��Ru�3�#O�v�1#�N|��5��ro�ך���x'�K���x�ۜ's�UY���uUݯ�;���aө3�*�̑�E�/�YMP�Sí�/�~�{&�o�o��j��q�(u-���̴ ��>�������N����w;o��#�ō�*ځT�ZG1H�=�B�P' H$�PJ]� }p�Ő��Y Let me write this. Expected utility is a theory commonly used in game theory and economics. But, the possibility of large-scale losses could lead to a serious decline in utility because of the diminishing marginal utility of wealth. 0000005854 00000 n 0000003711 00000 n 0000004098 00000 n In reality, uncertainty is usually subjective. Elderly households of modest means can more frequently become financially stressed by trying to keep up high nursing home insurance payments than by paying for nursing home care—which will eventually be covered by Medicaid. 0000013401 00000 n Expected utility do satisfy the weaker property, however, that they are preserved by a ﬃne (increasing linear) transformations. 0000008284 00000 n Applications of Expected Utility Theory. 0000010556 00000 n 0000017922 00000 n This makes sense because he is risk-loving. However, no rational individual would accept this. 0000015410 00000 n Uncertainty/ambiguity aversion 6. So his risk premium is −$21. (b) Find the expected utility for both Skippy and Myrtle when the insurance company uses the For example, for some individuals, the pain from losing $1,000 could only be compensated by the pleasure of earning $2,000. h@D�������qX:�� (hll��U�@��@+���M\\\\�:�X��`�fI܍@��F�v�[�lll�da$W G���R ���l�A*|L1 Abstract: We examine a problem of demand for insurance indemnification, when the insured is sensitive to ambiguity and behaves according to the Maxmin-Expected Utility model of Gilboa and Schmeidler (1989), whereas the insurer is a (risk-averse or risk-neutral) Expected-Utility maximizer. Well, his expected total cost of insurance, including medical costs, is lower with the low-deductible plan. A utility function is a representation to define individual preferences for goods or services beyond the explicit monetary value of those goods or services. In the next section I illustrate implications of the theorem with examples of the form "If an expected-utility maximizer always turns down modest-stakes gamble X, she will always turn down large-stakes gamble Y." Insurance: Going Beyond Expected Utility Theory . Expected Monetary Value (EMV) Example: You can take a $1,000,000 prize or gamble on it by flipping a coin. 1. For example, camera $50..$100. In his work, he presents the concept of declining marginal utility and its effect on decision making. Since the purpose here is not to support or detract from the expected-utility model, interested readers are referred to Hershey and Schoemaker (1980) and to Machina (1987). xref We’ll consider the foundations of this model, and then use it to develop basic properties of preference and choice in the presence of uncertainty: measures of risk aversion, rankings of uncertain prospects, and comparative statics of choice under uncertainty. 0000088676 00000 n endstream endobj 101 0 obj<> endobj 102 0 obj<> endobj 103 0 obj<>stream … I would rather not tote the umbrella on a sunnyday, but I would rather face rain with the umbrella than withoutit. Furthermore, agents’ behaviour in the real world seems to systematically break some of the axioms. Theoretical Justification for a Small-Stakes Insurance Incentive Scheme. Including the cost of insurance, what are Paul's expected total medical costs with the high-deductible plan? Subjective Expected Utility Theory. The utility function OU with a diminishing marginal utility of money income of a risk- averse individual is shown in Fig. 0000007083 00000 n 0000009710 00000 n "Utility" is the relative measurement of satisfaction to the outcome. Let's look at the high-deductible plan. For another example, Dana and Scarsini (2007) characterized the optimal risk sharing strategy between two parties, both being expected utility maximizers. 0000040039 00000 n Then the choice of action can be ~etermined by using expected utility value EUV in place of expected monetary value. 0000005611 00000 n Search for wildcards or unknown words Put a * in your word or phrase where you want to leave a placeholder. Humans all bet with their lives either that God exists or that he does not. So, if there is a 50% chance of making 10 US Dollars (USD) dollars and a 50% chance of making no money, the expected utility is $5 USD. 0000098035 00000 n Prudence coefficient and precautionary savings [DD5] 7. 0000007325 00000 n 0000012296 00000 n Outline 1.

The expected utility hypothesis is a popular concept in economics, game theory and decision theory that serves as a reference guide for judging decisions involving uncertainty. For example, "tallest building". 3.2.1 Counterexamples Involving Transitivity and Completeness . 0000010788 00000 n Several decision theories predict that insurance choices in small-stakes gambles will deviate from the optimal, rational choice given by expected utility, a theory that calculates the value of a risky choice as the sum of the product of the utility of each possible outcome multiplied by the probability of its occurrence. E-Forum, Winter 2012-Volume 2 4 In the example above, the person displays decreasing marginal utility … 0000095365 00000 n Economics 326: Expected Utility and the Economics of Uncertainty Ethan Kaplan October 3, 2012.
