A small exchange economy is comprised of two of individuals, A and B, and two types of goods, x,,x. The individuals' preferences over two goods are can be represented by the following utility functions: U*(x;,.x; ) = min (2x,t; ) and U* (x;,x,) = min(x;,. 2x, ). Initial endowments are 10 x, (individual A), and 10 x, (individual B). Calculate the price ratio which yields an equilibrium in the exchange market.

Two individuals (A and B) live on an island where they consume coconuts (good x) and bananas (good y) for survival. A owns the coconut producing part of the island and B owns the banana part. Their utility functions and endowments are given by UA (TA,YA) = A+YA +min {A, YA}, UB (TB, YB) = TB +YB + min {ïß, YB}, (ww) = (0, 12) B B Assume that the price of coconuts is p and that of bananas is 1, so relative prices are denoted by p. (ww) = (10,0) A 1. What are their respective budget constraints? 2. What are their individual demand functions? (Hint: you have to consider multiple cases for the value of p) 3. The individuals trade their endowments with each other. What is the competitive equilibrium price in the market? What are their respective utilities at equilibrium?
Consider a two-good exchange economy with two types of consumers. Type A have the utility function And an endowment of 3 units of good 1 and k units of good 2. Type B has the utility function And an endowment of 6 units of good 1 and 21 - k units of good 2. a. Find the competitive equilibrium outcome and show that the equilibrium price p* = p1/p2 of good 1 in terms of good 2 is p* = 21+k/15. b. Find the income levels (MA; MB) of both types in equilibrium as a function of k. c. Suppose that the government can make a lump-sum transfer of good 2, but it is impossible to transfer good 1. Use your answer to part b to describe the set of income distributions attainable through such transfers. Draw this in a diagram. d. Suppose that the government can affect the initial distribution of resources by varying k. Find the optimal distribution of income if (i) the SWF is W = log(MA) + log(MB) and (ii) W = MA + MB.
Consider an economy with 2 goods and 2 agents. The Örst agent has the utilityfunction, u (x1; x2) = ln x1 + 2 ln x2, and the other one has u (y1; y2) = 2 ln y1 + ln y2.The aggregate endowments of the 2 goods are given by (50; 100). Suppose there is asocial planner who cares about agents equally.(a) Set up the plannerís problem b) Calculate the first-best outcome (i.e., the social plannerís solution).
(5) A has utility function u4(x4) = x4 + x and initial endowment w4 = (3,6). Consumer B has utility function uB (xB) = xf · x% and initial endowment wB = (3,6). Consider an exchange economy with two consumers and two goods. Consumer (a) Is the initial endowment a Pareto efficient allocation? Justify your answer. (b) Find a competitive equilibrium (p, xª, x³) for the economy. (c) Construct the contract curve. A picture here is not a complete answer; you need to specify analytically the set of points that are in the contract curve.
An individual's utility function is given by: U (q1 , q2) = q11/2 . q2 Suppose we know that the individual is maximizing their utility by consuming 9 units of good #1 (q1=9) and six units of good #2 (q2=6). If the current price for good #1 is $1 (p1=1), what must be the price of good #2 (p2) and what must be the individual's current income (y) available to spend on the two goods? a.) p2 = b.) y=
Consider the following pure exchange, Edgeworth box economy. There are two consumers, Adam and Mark, and two goods. Adam has an endowment of 7 units of good 1 and 3 units of good 2 (i.e. wadam = (7, 3)), while Mark has an endowment of 3 units of good 1 and 7 units of good2 (wmark$ = (3,7)). The consumers' utility functions are given by: Uadam = Xa1 + Xa2 and Umark = min{xm1, Xm2) where x¡1 is the consumption of good 1 by consumer (i = adam, mark) (a) Find the set of Pareto optimal allocations of this economy (b) Find the Walrasian equilibrium.
In a two-good market, a consumer starts with an initial endowment of (x₁, x2) = (15.00, 5.00), while the market prices for these goods are given by (P1, P2) = (7.00, 3.00). The consumer has the following utility function: U 0.52 0.48 - Given this information, what will this consumer's final choice of quantity for each good be? x1 = x2 =

(1) Consider a small exchange economy with two consumers, A and B, and two commodities, ₁ and 2. Consumer A's initial endowment is 3 units of ₁ and 2 unit of 2. Consumer B's initial endowment has 5 units of 2₁ and 4 units of r2. Consumer A's utility function is given by U(₁, ₁) = x^x^. Consumer B's utility function is given by U(x,x) = 2x² + x2. Note that and are the amounts of the two goods for Consumer A, and rf and are amounts of the two goods for Consumer B. (a) Draw an Edgeworth box, showing the initial allocation. Label it as E. Measure Consumer A's consumption from the lower left and Consumer B's from the upper right. Also measure the number of ₁ on the horizontal axis and the number of r2 on the vertical axis. (b) Draw Consumer A's indifference curve (ICA) going through E. (c) Draw Consumer B's indifference curve (ICB) going through E.
