Assume a consumer has current-period income y = 200, future-period income y′ = 150, current and future taxes t = 40 and t′ = 50, respectively, and faces a market real interest rate of r = 0.05, or 5% per period. The consumer would like to consume according to the following utility function: U (c, c′ ) = ln(c) + ln(c′ ). Show mathematically the lifetime budget constraint for this consumer. Find the optimal consumption in the current and future periods and optimal saving. Suppose that instead of r = 0.05 the interest rate is r = 0.1. Repeat parts (a) and (b). Does the substitution effect or the income effect dominate?

Suppose that there are only 10 individuals in the economy each with the following utility function over present and future consumption: U (c1, c2) = c1 +C2, where ci is consumption today, and c2 is consumption tomorrow. Consumption tomorrow is less valued because people are impatient and prefer consuming now rather than later. Buying 1 unit of consumption today costs $1 today and buying 1 unit of consumption tomorrow costs $1 tomorrow. All individuals have income of $10 dollars today and no income tomorrow (because they will be retired) but they can save at the market interest rater> 0. How much of his or her income will an individual consume today given that the interest rate is 0.3? O. Less than half of it O. Exactly half of it O. The individual is indifferent between consuming today and saving O. More than half of it O. All of it O. None of it How much of his or her income will an individual consume today given that the interest rate is 0.5? O. Less than half of it…
Over a three-year period, an individual exhibits the following consumption behavior: Px Py x y Year 1 3 3 7 4 Year 2 4 2 6 6 Year 3 5 1 7 3 Is this behavior consistent with the axioms of revealed preference?
Assume you define your permanent income as the average of your income from this and the past four years. Your earnings record over these five years has been: Yt = 40,000, Yt-1 = 38,000, Yt-2 = 34,000, Yt-3 = 32,000, Yt-4 = 31,000. If your income increases next year to Yt+1 = 46,000, by how much will your consumption change if you always consume 90 percent of your permanent income?
In the two-period Fisher model of consumption, suppose that the first period income is $5,000 and the second period income is $5,000 for both Matt and Paola. The interest rate is 10 percent. Matt’s lifetime utility function is C1 + C2 while Paola’s lifetime utility function is C1 + 0.8C2. If there is a borrowing constraint, whose consumption is affected by that?
If Samantha's income is reduced to zero after she loses her job, her consumption will be ________ and her saving will be ________. Group of answer choices greater than zero; less than zero less than zero; less than zero greater than zero; greater than zero less than zero; greater than zero
An agent lives for 2 periods and gains utility only by consuming. Future consumption is discounted at rate θ where 0<θ<1. Agent consumes c, saves s at interest rate r in first period of life from income y. In second period agent consumes from savings plus interest earned but must pay a flat fixed tax. Find the Euler equation for this agent and what it shows.
Assume a consumer has a utility function U(x1, x2) = x1x2 where x1, x2 represents the amount of two goods 1 and 2 consumed in a given time period, find the utility-maximizing consumption function subject to the budget constraint5x1 + 4x2 <= 50
An investor with an initial endowment of $ 16,000 is confronted with the following productivity curve: C1= 240 (16,000 - C0)^0.5 where C0 denotes consumption at present, and C1 consumption in the future. Assume the interest rate (for borrowing and lending) is 20%.

Existence of representative consumer Suppose households 1 and 2 have one-period utility functions u(c1) and w(c2), respectively, where u and w are both increasing, strictly concave, twice-differentiable functions of a scalar consumption rate. Consider the Pareto problem: Subject to the constraint c1 + c2 = c. Show that the solution of this problem has the form of a concave utility function vθ(c), which depends on the Pareto weight θ. Show that vθ(c) = θu (c1) = (1 − θ)w (c2). The function vθ(c) is the utility function of the representative consumer. Such a representative consumer always lurks within a complete markets competitive equilibrium even with heterogeneous preferences. At a competitive equilibrium, the marginal utilities of the representative agent and each and every agent are proportional.

Section 1. Multiple Choice WITH Explanation. Choose the one alternative that best completes the statement or answers the question and EXPLAIN your reasoning. Do not forget to include equations, graphs, or any other material you believe is needed to understand your choice. To answer this problem assume a two-period economy with the following logarithmic utility function: U(C1,C2)=[ln(C1)+ln(C2)] where C1 and C2 are the consumption in the first and second periods, respectively. Households are endowed with Q1 and Q2 units of consumption goods in periods 1 and 2 and can borrow or lend at the world interest rate, r1=r*. Every household starts period 1 with B∗0≠ 0. Households can purchase bonds, B∗1, which pay the interest rate r1. The terms of trade in periods 1 and 2 are TT1 and TT2 , respectively. Then in this economy, the country adjust to____________________changes in the terms of trade by mostly changing____________________and the country adjusts to____________________changes in…
Assume an intertemporal budget constraint that shows how consumption can be traded off between two periods, t and t+1. Assume the consumer can save and borrow at the same interest rate of 10%. Assume the consumer collects income of $100 in each period. To gain an extra $10 dollars in period t+1, what must the consumer give up in period t?
