# risk and uncertainty in microeconomics

The economics of uncertainty impacts our … A fair insurance contract is one that would fully insure against this loss and charge the driver exactly the expected cost, or $50. Lower income households have more limited resourced with which to deal with the costs of a flood should they not have insurance. Unfortunately, running a business primarily depends on planning for a set of known outcomes. It is thus puzzling that price risk—that is, unexpected departures from a mean price level, or price volatility—has received so little attention. endstream endobj 195 0 obj <> endobj 196 0 obj <> endobj 197 0 obj <>stream Investing in a few firms in the same industry is risky because their risks are probably positively correlated. These issues These issues remain largely limited to the fields of microeconomics (Hey [1979]), finance (Copeland and We will only consider quantifiable risk in this module. For this reason, much of private insurance is priced beyond the risk premium of private homeowners. MICROECONOMICS I: CHOICE UNDER UNCERTAINTY MARCINPĘSKI Please let me know about any typos, mistakes, unclear or ambiguous statements thatyouﬁnd. This is exacerbated by the fact that it is common that homeowners in flood probe areas are disproportionately low-income households because flood prone land is generally cheaper than land in higher areas. They might remember that in the last ten years it has snowed in three of them. Not all individuals are risk averse. Figure 23.2.2: Risk Loving and Risk Neutral Utility Curves. ), the degenerate lottery that yields the amount R xdF(x) with certainty … In a coin flip, the probability of one side landing facing up is ½ or 50%. The … Risk averse individuals will always choose to purchase fair insurance. Fair insurance is a contract with an expected value to the insurer is zero – in other words a fair bet. You estimate that there is a 0.1 percent chance that the package will be lost or destroyed in tran-sit. For example, a homeowner might not have ever experienced a house fire but might make an inference about how likely they are based on their own knowledge of fires in their community and reports of fires they see in the news. The expected value of an uncertain outcome is the sum of the value of each possible outcome multiplied by the probability it will occur. Microeconomics (01:220:320). %PDF-1.6 %���� It was Frank Knight who first drew a distinction between risk and uncertain­ty. 206 0 obj <>/Filter/FlateDecode/ID[<18350D743DFD7B468F1DFCC6E35CE378><522AB398DAF72C46B2FCF003F03F2E0B>]/Index[194 36]/Info 193 0 R/Length 81/Prev 270382/Root 195 0 R/Size 230/Type/XRef/W[1 3 1]>>stream Learning Objective 23.2: Explain expected utility and risk preference. The utility of$75 for this agent is 130 as shown in the figure. The certainty equivalent method converts expected risky profit streams to their certain sum equivalents to eliminate value differences that result from different risk levels. Consumer choice under risk is usually analysed using the expected utility theory approach, while uncertainty is studied mainly in game theory. IntroductionGeneral Remarks Tourguide Introduction General Remarks Expected Utility Theory Some Basic Issues Comparing di erent Degrees of Riskiness Attitudes towards Risk { Measuring Risk … However, although different models have been developed for both situations, risk situations, … Introduction 2. What is the justification for government provision of flood insurance. The average outcome of the marble game is to earn $30. The Story So Far…. The risk premium is the amount an agent is willing to pay to avoid the risk of a fair gamble. If an accident occurs the cost of the damage will be$5000. Why don’t private insurers provide flood insurance? If there are multiple possible outcomes, probabilities can be assigned to each possible outcome. 194 0 obj <> endobj Download for offline reading, highlight, bookmark or take notes while you read Risk, Uncertainty and Profit. Often, the ability to mitigate risk though conscious choices requires information about the risks. Risk describes any economic activity in which there are uncertain outcomes. Therefore, they might estimate the probability of snow this year based on its annual frequency, 3/10, or .3, or 30%. Learning Objective 23.3: Describe how diversification and insurance mitigate risk. A person who is unwilling to make a fair gamble, like the person above, is risk averse. Even risk-neutral individuals avoid unfair risks and risk-loving individuals may wish to avoid very unfair risks. ... Utility and Risk Preferences Part 1 - Utility Function - Duration: 8:55. For example, a person who lives in an area that only rarely gets snow in the winter might wonder what the chances are that there will be snow this winter. Microeconomics (from Greek prefix mikro-meaning "small" + economics) ... then it is possible to scrutinize the actions of agents in situations of uncertainty. ϵ[0,1]. 1.2. Both texts provide a thorough account of modern thinking on the subject and a wealth of carefully chosen examples and problems. Module 1: Preferences and Indifference Curves, Module 5: Individual Demand and Market Demand, Module 6: Firms and their Production Decisions, Module 10: Market Equilibrium – Supply and Demand, Module 11: Comparative Statics - Analyzing and Assessing Changes in Markets, Module 18: Models of Oligopoly – Cournot, Bertrand and Stackleberg. If we look at the figure we see that point (d) on the graph of the utility function is at $65. In fact, a risk averse individual would be willing to buy insurance that is less than completely fair due to the risk premium which gives rise to the private insurance industry. Intermediate Microeconomics W3211 Lecture 23: Uncertainty and Information 1: Expected Utility Theory Columbia University, Spring 2016 Mark Dean: mark.dean@columbia.edu 1. In general, two approaches are used to estimate the probabilities of decision outcomes. Uncertainty is a condition where there is no knowledge about the future events. Pr. Share. All of these scenarios are examples of uncertainty and uncertainty implies risk. ;���VI�NIZ�?�֐i�+�&�AN�ϊ�sL�h&$ C�oq�#��zZ�ĉ>�=S��6#3e��M��9�&�DU�ţ�H��K'Tr �'�v&���H�^�f=g��Z�S�=�:yC^���g��/�Ϝ3�^I��a7��*���XI�a������ë�[�/�on�go�n(�,,V"��㫁%����ٺ����3m}�����oo%��� �^I�~�(�@Q��^�O����IOY��6����A&��#� In either case the ability to assign probabilities distinguishes these risks as quantifiable. The expected value (EV) of one random draw is: EV = Pr(Red) x Value(Red )+ Pr(Blue) x Value(Blue), + Pr(Green) x Value(Green) + Pr(Yellow) x Value(Yellow), EV =.4 x $10 + .2 x$50 + .3 x $20 + .1 x$100 = $30. The private insurance industry relies on diversified risk in order to stay in business. The graph of the utility function has a declining slope as wealth increases. Outline Answer: No you should not. However, the world is filled with uncertainty. 7 What is the difference between risk and uncertainty? In other words, the guaranteed amount of$1600 yields higher utility than the gamble that has an expected value of $1600. Thus the expected loss is (.1)($5000) or $50. With a 80 percent chance, you will win$400 and with a 20 percent chance you will win $2500. We review and extend the economic analysis of risk and uncertainty as it relates to behavior mitigating health shocks. So this agent prefers more wealth to less but the marginal utility of wealth is decreasing. Theoretical possibilities considered in the context of decisions under conditions of risk include: Expected value maximization, Expected utility maximization, Rank dependent utility maximization, Prospect theory, and the Topology of … The expected utility from the above gamble is: To look at a specific example, suppose a person’s utility can be expressed as a function of money in the following way: Then the expected utility from the above gamble is: $EU=.6\, x\,\sqrt{1000}+.4\,x\,\sqrt{2500}=.6\,x\,31.62+.2\,x\,50\approx 29$, As with utility in general, this number does not mean anything in absolute terms, only as a relative measure. Advanced Microeconomics - The Economics of Uncertainty J org Lingens WWU Munster October 17, 2011 J org Lingens (WWU Munster) Advanced MicroeconomicsOctober 17, 2011 1 / 88. In this case the risk premium is$10. University of Chicago economist Frank Knight wrote about the difference between one kind of uncertainty and another in his stock-market-oriented economics text Risk, Uncertainty and Profit. The formal incorporation of risk and uncertainty into economic theory was only accomplished in 1944, when John von Neumann and Oskar Morgenstern published their Theory of Games and Economic Behavior - although the exceptional effort of Frank P. Ramsey (1926) must be mentioned as an antecedent. Usually expressed as a fraction of 1. For example, a person who places a bet on the flip of a coin faces two different outcomes with equal chance. Lecture 10: Risk and Uncertainty - Microeconomics 33001 with Shivakumar at University of Chicago Booth School of Business … Associated with any uncertain outcome are probabilities. A farmer, for example, cannot avoid the inherent variability of the weather. They look at the data and models available to them, but use their own experience as a guide to how to interpret the data and model predictions and make their own assessment. Take mortgage insurance, for example. However, if you invest in many firms across a wide range of industries, it is likely that some will do well while others do poorly and therefore the overall risk will be reduced. Tomas J. Philipson & George Zanjani. c�] u�e� �� The Geneva Papers on Risk and Insurance , 13 (No 46, January 1988), 96-99 Uncertainty in Macroeconomics and the Microeconomics of Uncertainty* by Henri Loubergé** Professor von Furstenberg's lecture on "Uncertainty in Macroeconomics" [1988] has presented a very comprehensive survey of the problems raised in current macroeconomic research. A fair gamble is one where the cost of the gamble is equal to the expected value. But there are some actions individuals can take to mitigate risk: drivers can drive more carefully, farmers can plant drought resistant crops, travelers can avoid airlines with poor safety records. Discrete probability Probability: The relative frequency with which an event occurs. Normally these risks are quite diverse, particularly if the insurer insures mortgages across a diverse geographical area so that an economic downturn in one city, like the closure of a large employer, will not cause too may claims at one time. For example, in order to lower risk from air travel, a traveler would need access to the safety records of airlines. Frequency is how often a particular outcome has occurred over a known number of events. Economic Analysis of Risk and Uncertainty induced by Health Shocks: A Review and Extension. A company develops a product of an unknown quality. “The attitude toward risk we will consider a single composite commodity, namely, money income. This diversification requires that the risks are perfectly negatively correlated. An insurance company o⁄ers you insurance against this eventuality for a premium of 15AC. The difference between risk and uncertainty can be drawn clearly on the following grounds: The risk is defined as the situation of winning or losing something worthy. Much insurance is provided by the private market, but one important exception is flood insurance, which is generally provided by the federal government in the United States. The Economics of Uncertainty and Information may be used in conjunction with Loffont's Fundamentals of Economics in an advanced course in microeconomics. Graph of Risk Neutral and Risk Loving Utility Curve. This lecture analyzes the implications of uncertainty for consumer decisions. Ronald Moy 219,739 views. Equivalently, a risk averse person will always reject a fair gamble. Consider two possible outcomes, $50 and$100. People understand that in the future there is a possibility that they will fall ill or suffer an injury that requires medical attention. He can participate in a fair gamble. They generally do so in two ways: they can estimate based on frequency or based on subjective probability. Taking two quick stops at Webster’s, 2 we find the following:. Recall that probabilities are numbers between zero and one that indicate the likelihood that a particular outcome will occur. ���j/A��#�xD���@��#��;$�o�e�6��q����ү ��+ Risk and Uncertainty in Project Management and/or ID # Teacher Inherent in any activity in business or in life there is always present some degree of risk and uncertainty. The expected utility is the average of the utility levels at the two outcomes and can be seen as the midway point on the chord that connects the two points on the utility function. If you are risk-neutral, should you buy insurance? If there are 40 red marbles, 20 blue marbles, 30 green marbles and 10 yellow marbles then the probability of randomly drawing a red one is .4 (40/100), a blue one is .2, a green one is .3 and a yellow one is .1. ��#8��{��x�ZZr�����a����ۻ���e��N([�v �m7Y\�U�&�pj��n��||}�ۿ�>;��>�}޿:=��ܾ�}ػ�a{v��������|�#'����՛[�e~����h����]\����o�z�^��my��g�~w���u�����]�~��ͻ�; y{�߽��P������Y������Ǜ�o}O9��ӗ�ڦ�e��J��&��ˆ��ꦸ܀)4�O%Q��!��$>���r�.ճ$�6�G��gie���F�@�Q�Q$��rF��� 2w�4?x�$�J�J���? If an insurer has 1000 clients, each with a 1% risk of needing to make a claim, it is necessary that the 1% risk is not too positively correlated to avoid situations in which too many insured make claims in thee same year. MWGchapter6.A.Kreps“NotesontheTheoryofChoice”, chapters4and7(theﬁrstpartonly). Surprisingly, risk and uncertainty have a rather short history in economics. Suggestedreadings. Study 17 Lecture 10: Risk and Uncertainty flashcards from Andi H. on StudyBlue. The difference between the expected value of the gamble,$75, and the amount of the certain payment that yield the same utility as the gamble, $65, is called the risk premium. This makes insuring against floods very difficult for private insurers who struggle to diversify their risk portfolio and puts them in danger of a catastrophic payout should a flood occur. Even when we don’t know the probabilities we can often estimate based on aggregate data or some other information such as if the roads are covered in snow. A common way that individuals reduce risk is through the purchase of insurance. Risk-averse homeowners whose houses are situated in areas that have a possibility of flooding will have a demand for insurance as long as the insurance contract is within the risk premium the homeowners are willing to pay. hެYYo7�+|4óX�d!�k;N�l�~P�[�/H���[���[���&ndZ�!���K�TjT�r���d��ˡ��ѻP#��k�Ft�xbr�"M�ٕ�+ Intermediate Microeconomics by Patrick M.

Applied. risk and uncertainty have not been yet seriously considered at the global level. This means that playing this risky game yields a utility of 110 for this agent. A weather forecaster is also making a subjective probability estimate when forecasting a chance of rain. When a flood happens, most homes in the flood area are severely damaged so the risks are very highly positively correlated. The insurance company relies on the fact that it can expect, on average, 10 claims a year to keep its business going and not suffer a catastrophic loss from too many insured filing claims in the same year which could bankrupt them. endstream endobj startxref This is normally a safe strategy but the housing crisis in the United States in 2006 spread across the entire country which lead to a number of mortgage insurers falling into deep crises, most notably American International Group (AIG) which was bailed out by the U.S. Government to the tune of$180 billion dollars and led to the government taking control of the firm. Example: win €1 if a coin lands on heads and lose €1 if it lands on tails. Remember that the value of the utility has no meaning in absolute terms, only in relative terms. Modern decision theory is based on this distinction. Figure 23.2.2 illustrates both situations using the same scenario as in Figure 23.2.1. (1989), ‘Choice under Uncertainty; Problems Solved and Unsolved’, Journal of Economic Perspectives, 1 (Attempts to shore up the theory of choice under uncertainty on ‘solid axiomatic foundations’ of probabilistic risk in the face of the famous St Petersburg paradox and other challenges to expected utility theory.) An individual with a constant marginal utility of wealth is risk-neutral and an individual with an increasing marginal utility of wealth is risk-loving. By Nobel Laureate Professor Thomas Sargent "I will talk about the distinction between risk and uncertainty and its influence on valuations and decisions. Microeconomics CHAPTER 8. Intermediate Microeconomics UNCERTAINTY AND RISK BEN VAN KAMMEN, PHD. For example, consider a jar of 100 marbles of four different colors: red, blue, green and yellow. h�bfR�l� ���OT�� +��\��]���g���u���!C��b ���v3H5�f�=<5�ݓyB���+׮�sn ��M��dӲ7O���w�D�����}{�K����7�HZs{��I�����&���\v�������k���L�x�ްDcڛ�=�o&{K}���r��w�i&���8v1���IR�3*��bM Z�(�"�Al� �RTR��� $T� �P�U�� �i� f�� Example 1.

Risk averse individuals are willing to pay a price to avoid or lower risk. Figure 23.2.1 illustrates a person with a utility function with regard to wealth that is risk averse. For example, consider investing in the stock market. Fair Gamble: A gamble with an expected outcome of zero. But how much would you be willing to pay to play this game? Suppose also that red ones are worth$10, blues ones are worth $50, green are worth$20 and yellow are worth $100. In order to answer that, we need to know about expected utility. Suppose there is a 1% chance a driver will have an accident in a year. This contract offers no profit for the insurance company, however. UNCERTAINTY AND RISK Exercise 8.2 You are sending a package worth 10 000AC. 1. Syllabus Economics 9010 Advanced Microeconomics I. Similarly, economists have studied behavior in the face of risk and uncertainty for at least a century, and risk and uncertainty are without a doubt a feature of economic life. If instead this person were given the expected value of the gamble,$1600, for certain note that they would get. Learning Objective 23.4: Apply knowledge of risk and insurance to explain how systematic risk makes risk pools difficult and destroys private markets for insurance. Fair gamble = a gamble where the individual gets nothing on expectation. A driver of a car knows that there is a chance of a collision. Machina, M. J. Read this book using Google Play Books app on your PC, android, iOS devices. 229 0 obj <>stream It is precisely this diminishing marginal utility of wealth that leads to risk aversion. Risk can be measured and quantified, through theoretical models. Uncertainty is the lack of information, which makes the probabilities of a defined outcome unknown. For example, a person who places a bet on the flip of a coin faces two different outcomes with equal chance. This means that the agent has a 50% chance of getting $50 and a 50% chance of getting$100. We don't know if it will rain tomorrow, if the stock market will go up next year, or if a new business will succeed or fail. Expected Value: An average of probable outcomes weighted by how probable each outcome is. For this module, as in economics in general, we use the terms risk and uncertainty interchangeably. But flood insurance is not easy to acquire on the private market. Risk, Uncertainty and Profit - Ebook written by Frank Hyneman Knight. Note that there is no risk premium for the risk-neutral individual and the risk-loving individual would actually suffer a cost of the gamble were removed. Risk-averse individuals wish to diminish or eliminate entirely the risks they face. In this course we will explore the important topics of uncertainty and information in economics. We also learn about alternative approaches, such as the Friedman-Savage and Markowitz perspectives, but especially Daniel Kahneman’s prospect theory. Insurers will cover the loss to banks if a homeowner with a mortgage defaults. This is an Upper-Level Elective in the economics curriculum. Twitter LinkedIn Email. A person who prefers the gamble to the guaranteed fair payout is risk loving. Coping with these concepts in strategic ways is an important part of a well-run organisation or project as well as a life well lived. Definition (Risk Premium π): Maximal amount of money that an individual is willing to pay to escape a pure risk u(w-π(u,X))= Eu(w+X) with EX=0. Knightian Uncertainty . Introduction 1.1. Formally if k equals the number of times an event has occurred and N equals the number of times possible, then the frequency, F, equals: Subjective probability is when individuals estimate probabilities based on their own experiences and whatever data are available to them. Risks that are negatively correlated in general can be combines to reduce overall risk. ��wXo�K6l3J�d��tN�V�b�J9��"qK�r�Q)�ā�M�j��?A�v�lU"U�������_��r�9b҅�!ŭ*H:L�m�8 f��e{����R>Ʌm6��. Sometimes it is said that risk is a known-unknown while uncertainty an unknown-unknown, since in the latter agents cannot (or will not) assign probabilities to each outcome. When the level of risk and the attitudes toward risk taking are known, the effects of uncertainty can be directly reflected in the basic valuation model of the firm. The reason for this is the fact that most people who wish to purchase flood insurance own homes in flood prone areas. Floods are relatively uncommon but very costly. Sometimes these probabilities are known, like in the coin flipping example, and sometimes these probabilities are unknown, like in the car collision example.
