Let preferences of both individuals be given by log(ci)+ log(c). Suppose that the endowment vectors are wA = (5, 10) and wB price and the equilibrium consumption bundles of each individual. (10,5). Solve for the market clearing

= 5. Consider an economy with a single (representative) agent with utility function u(x, lc) = x¹/514/5 and an endowment of 0 units of x and 10 units of time, which the agent can use as leisure (c) or labor (L) (i.e., L + lc = 10). The agent owns a firm that produces good x using L as an input, with technology of production given by x(L) = 3√L. Let the price of x be p = 1 and let w denote the price of time (i.e., the price of leisure and the wage). Find the competitive price of time w and the competitive allocation.

Suppose that you want to derive and draw the demand function for Mr. Seong (also known as Player 456). Mr. Seong likes to eat Dalgona Candy (D) and drink Soju (S). Suppose Mr. Seong's preferences can be expressed as U(D,S) = (D)º.² · (S)0.8. Suppose further the price of a Dalgona Candy is 2 (pº = 2) and the price of Soju is 4 (ps = 4). Mr. Seong has a budget of 100 to spend on the two goods. A. Use the substitution method to find Mr. Seong's optimal choice of Dalgona Candy and Soju. B. Use any method to find Mr. Seong's optimal choice of Dalgona Candy and Soju if the price of Soju was 5 (instead of 4). Feel free to use the Cobb-Douglas short-cut method if you want. C. Use your answers to A and B to derive the demand for Soju in the two diagrams below. That is, draw the change in the top diagram and then use your result to derive the demand curve in the bottom diagram. Several hints have been drawn in the diagram below.

Consider a pure exchange economy with two goods k = 1,2 and two households i = A, B. The total available amount of good 1 and 2 is 9 and 12 units, respectively. Utility functions for households A and B are UA (TA1, A2) = TA1TA2 and UB(B1, B2) = XB1T32. (a) Find an expression for the Pareto optimal set. (b) Assume e A = (4,4) and eg (5,8) are A and B endowments, respectively. Find the competitive equilibrium. (c) Is the competitive equilibrium allocation in the Pareto Optimal set? Why this result should not surprise us?

Suppose that consumer has the following utility function: U(X,Y) - X1/2y1/4. Suppose also that P 2, P -3 and 1=144. What would be the optimal consumption of X and Y at the equilibrium. respectively? 36, 24 12,40 24,32 48.16

In an environment in which all education is privately provided, suppose that a family with one child has $20,000 per year to spend on private goods and education. Draw this family’s budget constraint. Suppose now that an option of free public education with spending of $4,000 per pupil is introduced to this family. Draw three different indifference curves corresponding to the following three situations: (a) a free public education would increase the amount of money that is spent on the child’s education; (b) a free public education would decrease the amount of money that is spent on the child’s education; (c) a free public education would not affect the amount of money spent on the child’s education.
