Consider the problem of an individual that has Y dollars to spend on consuming overtwo periods. Let c denote the amount of consumption that the individual would liketo purchase in period 1 and c2 denote the amount of consumption that the individualwould like to consume in period 2. The individual begins period 1 with Y dollars andcan purchase cı units of the consumption good at a price P and can save any unspentwealth. Use sı to denote the amount of savings the individual chooses to hold at the endof period 1.Any wealth that is saved earns interest at rate r so that the amount of wealth theindividual has at his/her disposal to purchase consumption goods in period 2 is (1+r)81.This principal and interest on savings is used to finance period 2 consumption. Again,for simplicity, we can assume that it costs P2 dollars to buy a unit of the consumptiongood in period 2.2The individual's total happiness is measured by the sum of period utility across time,u(cı) + u(c2). Let u(c) be an increasing function that is strictly concave in the amountof consumption c enjoyed by the individual. Also assume that the function u(c) satisfiesthe Inada condition lim→0 u'(c)utility function u(c) with respect to c.= o where u'(c) = au) is the first-derivative of thedc The individual's total happiness is measured by the sum of period utility across time,u(c1) + u(c2).

The diagram depicts Julia's choice of consumption in periods 1 and 2. She has no income in period 1 and an income of $100 in period 2. Based on this information, which of the following statements is correct? Julia's endowment 100 67 23 Feasible frontier (10% interest rate) Feasible frontier (76% interest rate) 30 56 70 91 Consumption now (S) Select one: o a. When the interest rate is 78%, the maximum that Julia can borrow in period 1 is $56 (rounded to the nearest dollar). O b. When the interest rate is 78%, a consumption plan of $30 in period 1 and $67 in period 2 is in Julia's feasible set O C. When the interest rate is 10%, the marginal rate of transformation of goods from period 2 to period1 is 0.1 O d. When the interest rate is 10%, if Julia borrows $23 in period 1 then she can consume $70 in period 2 Consumption later ($)
Penelope utility function is U (a, b) = a+ 10b−b2, where a is the amount of applesconsumed and b is the amount of bananas consumed. He has $100 income. Theprice of apple is $0.5 per lb. Price of banana’s though increases with its purchase.Specifically, buying, b pounds of bananas will cost Pedro b2.a. What is Penelopes optimal consumption?b. Now, he suddenly acquires an extra $100 income. How this will changehis allocation?
January is choosing how much of pudding (measured on the horizontal axis) and how much of meat (measured on the vertical axis) to purchase with limited budget of $100. The price of pudding is $1.25 per pound and the price of meat is $3.75 per pound. Suppose the consumer wants to purchase the consumption bundle (20,40). This consumption bundle will be attainable O None of the other alternatives are correct O unattainable O efficient

Consider a 2-good economy and a consumer endowed with a positive net income m. If the unit prices of goods are p1 and p2 with p1=2p2 and the consumer is invariably indifferent between 5 units of the first good 1 and 8 units of the second good 2. Than the consumer will choose to consume amounts x1 of the first good and x2 of the second good such that; P1x1=p2x2 X=0, x2>0 X1>0, x2=0 None of the answers is correct.

1. An individual derives utility from the consumption of a basket of goods, c and leisure time, given by U(c, l) =cºl(1-a) where 0 < a < 1, is a constant; and must decide how to allocate her time between work, L and leisure to maximize her utility. The individual has a total of 24 hrs in a day (L + l = 24) and total consumption is constrained by her income; i.e., c = wL, where w the real per hour, is taken as given. (a) Solve for the optimal labor supply.
Tia and Lia consume bread (R) and clothes (B) with the following utility functions: Tia : UT = 30 R0.25 B0.75Lia : UL = 50 R0.5 B0.5 It is known that the price of bread (Pbread) is Rp. 100,000 while the price of clothes (Pclothes) is Rp. 300,000 If Tia currently consumes 5 pieces of bread and 10 clothes, while Lia consumes 12 pieces of bread and 18 clothes, specify: a. Have Tia and Lia reached an efficient allocation level? Use calculations and the Edgeworth Box to help your explanation. b. If it turns out that the level of consumption is not efficient, what is the consumption of each to reach the Paretto Optimum? Use calculations and the Edgeworth Box to help your explanation.
Maria has a fixed weekly budget which she has been spending on goods A, B, and C. Her utility function exhibits a diminishing marginal rate of substitution. She uses the equi-marginal principle to decide how much to purchase of each product. Suppose that for Maria's current consumption bundle it holds that MUA MUB MUC PA Рв PC You may assume that she has spent her entire budget. If Maria wishes to maximise utility, next week, she should A) buy product A only. B) buy products B and C only. C) buy less of A and more of B and C. D) buy more of A and less of B and C.
