John and Belle consume only two goods, x and y. They have strictly convex preferences and no kinks in their indifference curves. At the initial endowment point, the ratio of John's marginal utility of x to his marginal utility of y is J and the ratio of Belle's marginal utility of x to her marginal utility of y is B, where J < B. The competitive equilibrium price ratio is px/py = C. Which of the following is true? a. C> B. b. C < J. c. C = J. d. C = B. e. ]

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…

Two friends, Karol and Manuel, like to drink kombucha (x₁) and matcha (x₂). Both X₁ and X2 are expressed in ounces. The following utility function represents Karol's preferences: 1 1 2 2 u (x1, x2) = x1 x3 The following utility function represents Manuel's preferences: u (x₁, x2) = √√x1 + x2 Karol's income in dollars is denoted by mk, and Manuel's income is denoted by mm. Both face the same prices in the market, denoted by p₁ and p2, for kombucha and matcha, respectively. Both prices are expressed in dollars per ounce. Assume p₂=1 throughout the whole question. 1) Draw Karol's and Manuel's indifference curves in separate graphs and describe any important similarities or differences between the two.

9. Consider an Edgeworth box economy with two consumers, whose utility func- tions and endowments are u'(x},x}) = (x}Xx})} (5,5) In the following, use the normalization p2 = 1. (a) Find the competitive equilibrium price. (b) State the first fundamental theorem of welfare and verify that it holds in this economy. (e) Consider the allocation ĩ = (x',) = (2,3), (8, 7). Show whether this allo- cation can supported as an equilibrium with transfers. (d) State the second fundamental theorem of welfare, and briefly discuss whether the result in part (c) conform with or violate this theorem. 3.
