Mortimer lives for two period and has utility function U = C1*C2. He earns no income in period two and his income in period 1 is $80,000. The interest rate at which he can borrow and lend is 10%. Calculate his optimal consumption in each period.
1. Harvey Habit's utility function is U (C1, C2) = min {c1, c2}, where ci is his consumption of bread in period 1 and ca is his consumption of bread in period 2. The price of bread is $1 per loaf in period 1. The interest rate is 21%. Harvey earns $2,000 in period 1 and he will earn $1,100 in period 2. (a) Write Harvey's budget constraint in terms of future value. (b) How much bread does Harvey consume...
Let the consumer’s utility function be given by U(x1,x2)=(x1-c1)α(x2-c2)1-α, where c1,c2>0 and 0<α<1. Let the prices of the two goods be p1 and p2 and consumer’s income be M. solve for the optimal quantity of x1 and x2
2. Consider the following four consumers (C1,C2,C3,C4) with the following utility functions: Consumer Utility Function C1 u(x,y) = 2x+2y C2 u(x,y) = x^3/4y^1/4 C3 u(x,y) = min(x,y) C4 u(x,y) = min(4x,3y) On the appropriate graph, draw each consumer’s indifference curves through the following points: (2,2), (4,4), (6,6) and (8,8), AND label the utility level of each curve. Hint: Each grid should have 4 curves on it representing the same preferences but with different utility levels. 3. In the following parts,...
Suppose that a household has a utility function and intertemporal budget constraint as follows: U(C1,C,) - (cº:" + Bc2:5)1-y U(C1,C2) = - 1- ITBC: C1 + = yı + 1+1 a) Determine the marginal rate of substitution for this utility function and derive the Euler equation faced by this consumer (define the Lagrangian and then obtain first order conditions as we did it in the lecture). Explain the intuition of the Euler equation. b) Find a solution for optimal consumption...
