Please answer the question fully and completely else I will rate negative, thanks! Question 3 Consider an economy with two consumers, A and B, two goods called 1 and 2 and one firm. Consumers A and B are each endowed with a unit of each good. The utility functions of each consumer are: A: 13 4 4 u (x₁‚x2 ) = lnx₁ + Inx2 B:u ₁₂ (x, ‚ x 2 ) = x, x 2 The firm B 1 A 1 1 2 produces good 2 using good 1 as an input, according to the production function f(y) = y where y is the quantity of good 1. Consumer A is the sole shareholder of the firm and the firm operates to maximize profit. Page 2 If P₁ and P2 determine the utility maximizing demand of consumer are the per unit prices of goods 1 and 2, . B for each good as a function of p, and P2 · If P₁ P 2 1 and are the per unit prices of goods 1 and 2, determine the profit maximizing demand of the firm for good 1 as a function of p₁ and p2. Ifp, and p2 are the per unit 1 prices of goods 1 and 2, determine the utility maximizing demand of consumer…
Consider a market with two households (A and B) and two goods (X and Y). Each household holds 12 units of each good. Household A has a utility UA = 5 In LA + In yA when it consumes bundle (*A, YA). Household B hasa utility UB = In aB+5 Inyg when it consumes bundle (гв, ув). The market reaches an equilibrium when the price of each good is $1. Which, of the following sentences, correctly explains what happens in the market? Household A purchases 8 units of good X from household B. Household B purchases 8 units of good Y from household A. Household A purchases 7 units of good Y from household B. Household B purchases 7 units of good X from household A. Household A purchases 9 units of good X from household B. Household B purchases 9 units of good Y from household A. O Household A purchases 7 units of good X from household B. Household B purchases 7 units of good Y from household A. Household A purchases 9 units of good Y from household B. Household B purchases 9 units of good X from…
Consider the pure exchange economy with 2 goods, good 1 and good 2, and two consumers, consumer A and consumer B. The consumers have the following utility functions: UA(X1A,X2A)=X1A+3x2A; UB(X1B,X2B)=x1B +X2B. Consumer A is initially endowed with 4 units of good A and no unit of good 2, that is, consumer A's initial endowment is (W1A,W2A)=(4,0). Consumer B is initially endowed with 3 units of good 2 and no unit of good 1, that is, (WIB,W2B)=(0,3). In order to implement the allocation (x1A,X2A)=(0,1), (x1B,X2B)=(4,2) as a Walrasian equilibrium, what transfer of wealth should we make between the consumers if good 1 is the numeraire, that is, if p1 =1? O a. An amount 7 of wealth should be transferred from consumer A to consumer B. O b. None of the other answers. An amount 3 of wealth should be transferred from consumer A to consumer B. O c. d. An amount 3 of wealth should be transferred from consumer B to consumer A. An amount 7 of wealth should be transferred from consumer B to consumer…
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?

Consumer equilibrium exists when: P/MU of all goods is the same MU/P for all goods is the same TU/P for all goods is the same the MU for all goods is the same
Suppose there are two consumers, A and B, and two goods, X and Y. Consumer A is given an initial endowment of 3 units of good X and 5 units of good Y. Consumer B is given an initial endowment of 5 units of good X and 3 units of good Y. Consumer A's utility function is given by: UA(X,Y)= X + 4Y, and consumer B's utility function is given by UB(X,Y)= MIN (X, 2Y). If the prices are Px = 1 and Py = 3, if each consumer sells her initial endowment and buys back her optimal bundle, which of the following statements is true? Group of answer choices Both Markets are in Equilibrium There is Excess Demand in the Market for Good X = 2.4 There is Excess Demand in the Market for Good Y = 0.8 There is Excess Supply in the Market for Good Y = 1.6 There is Excess Supply in the Market for Good X = 1.6 E
2(b)There are three people and two goods in an economy. The utility functions and the initial bundles are given below: U1 = X11X 12 U = 2x 21+ X 22 U3 = X 31 X 3z+X 32 W; = (0,8) W;= (2,2) Wy= (8,0) Suppose it is suggested that the three traders move to the allocation x given by x;= (1,2), x2= (8,4), X3= (1,4) b. Show that x makes no one worse off than the original allocation.

For the case of two goods, give examples of different two utility functions that satisfy all of the following properties: (i) one utility is strictly concave in good 1 and the other is strictly convex in good 2; (ii) they represent the same preferences; and (iii) one utility function is homogeneous of degree 2.
