4. Consider a society that has three individuals - 1,2 and 3 - and three alternatives - x, y and z. The society has a preference aggregation rule F. In year 2007, the profile of individual preferences were as follows: 1 2 3 X y Z y Z V It is known that the rule F satisfies Completeness, Transitivity, Anonymity, Unanimity and Independence of Irrelevant Alternatives. Also, in year 2007, F ranked x strictly above y. Now, we are in year 2008. The individual preferences have changed to: 1 2 3 Z y y X Z Z y X x (a) How does the society rank between y and x in 2008? Why? (b) How does the society rank between x and z in 2008? Why? (c) How does the society rank between y and z in 2008? Why? (d) What were the social preferences over all three alternatives in 2007?

Suppose that the following Cobb-Douglas utility function is given U(X,Y) = X³y/2, Which of the following is correct? O Law of diminishing Marginal Utility holds for good Y but not for good X while Law of Diminishing Marginal Rate of Substitution holds. Law of diminishing Marginal Utility holds for good X but not for good Y while Law of Diminishing Marginal Rate of Substitution holds. Law of diminishing Marginal Utility holds for good Y but not for good X while Law of Diminishing Marginal Rate of Substitution fails to hold. Law of diminishing Marginal Utility holds for both goods and Law of Diminishing Marginal Rate of Substitution holds as well

Question 3Draw indifference curves for the following sets of preferences and indicate the direction inwhich the individuals’ satisfaction (or utility) is increasing. Be specific about slopes when itis necessary. Assume for both parts (a) & (b) that soft drinks are measured on x-axis andhamburgers on the y-axis. (a) Mary always gets twice as much satisfaction from an extra hamburger as she does froman extra soft drink. (b) Bob loves soft drinks but dislikes hamburgers.
In the standard notation of our revealed preference analysis, suppose p^cC < p^CA < p^cB and p3cB < pBcC. Select one: Select one: a. These conditions are consistent with well-behaved preferences and imply only that situation A is revealed weakly preferred to situation C. b. These conditions are consistent with well-behaved preferences but tell us nothing about the preference ranking of the three situations. O c. These conditions are not mutually consistent with well- behaved preferences. O d. These conditions are consistent with well-behaved preferences and imply that situation C is revealed weakly preferred to situation B and situation A is revealed weakly preferred to situation C.
Zach's preferences are representable by the utility function u = 90.3927, where 9₁ and 92 denote his consumption of goods 1 and 2. (Answers to each of these questions are rounded, where required, to two decimal places.) Still assuming endowments of e₁ = 5 and e₂ = 9 and market prices p₁ = 20 and p2 = 30, what is the maximised value of Zach's utility? O Au= 6.74 O B. u = 5.39 O Cu = 5.65 O D.u = 7.56 O E.

In class discussions about uncertainty we assumed that the utility levels in each state of nature depends on c, which we might interpret as some aggregate con- sumption and we expressed utility as U(c). Now, let's extend this to a case where the utility level depends on consumption of two goods (this was the type of utility we used mainly in this course). Ben is a farmer who grows wheat and barley. However, his harvest is uncertain. If weather is good, he gets 200 lbs of wheat and 200 lbs of barley. If weather is bad, he gets only 100 lbs of wheat and 100 lbs of barley. His utility in each state of nature is U(w, b) = w¹/4b³/4, where w and b represent his consumption of wheat and barley, respectively. Prices of wheat and barley are $1 in both state of nature. The probability of good weather is T. Question 3 Part a Express Ben's expected utility function. (Hint: find Ben's optimal consumption in each state of nature first) Question 3 Part b Let's assume = 0.5. Knowing that bad weather…
