Problem 1. Consider the problem of an agent at date t, who marimizes the utility function に0 subject to a sequence of budget constraint, where B is the discount factor, c+k is consumption in period t+ k and 1/η is the intertemporal elasticity of substitution Let P+k be the price level prevailing at date t+k, i.e. Pt+k Dollar buy 1 unit of the consumption good in period t +k. Among the various assets that the agent can trade at date...

Problem 2. Consider an overlapping generations model with money, where t = 1,2,3,.... So, every period t, a generation of two-period lived agents are born. Their preferences are . They are endowed with ey units of the consumption good, when young, and e° units of the consumption good, when old. Assume that ey > eo > 0. The consumption good is perishable The initial old also have a quantity M of intrinsically valueless fiat money. Trading takes place as described...

1. Consider an agent who values consumption in period 0 and 1 according to the following utility function: u(co, C)In(Co)+8 In(c1) is a discount factor (5 < 1) which indicates that the agnet prefers to consume today more than he can tomorrow. Suppose that the agent is given a total wealth today of w and that he may save any portion of this money in order to consume tomorrow. If he saves money he is paid interest r. Thus the...
which formula does this question use? And, Why
Vder=pi+0+0+0+...(why it is a zero)

Consider a bargaining problem with two agents 1 and 2. There is a prize of $1 to be divided. Each agent has a common discount factor 0 < δ < 1. There are two periods, i.e., t ∈ {0,1}. This is a two period but random symmetric bargaining model. At any date t ∈ {0,1} we toss a fair coin. If it comes out “Head” ( with probability p = 21 ) player 1 is selected. If it comes out...
Consider an economy occupied by two households (i- A, B) who are facing the two-period consumption problem. Each household i - A, B is facing the following utility maximization problem: max subject to ci +biy(1+r)bo where Vi and US are household i's exogenous income in period t 1.2. cỈ and c are household i's consumption in period t 1,2. bo,bi is household i's bond holdings of which bo is exogenously given, r is the real interest rate, and 0 <...
Consider a household living for two periods, t = 1, 2. Let ct and yt denote consumption and income in period t. s denotes saving in period 1, r is the real interest rate and β the weight the household places on future utility. The following must be true about the household’s consumption in the two periods:c1 = y1 − sandc2 = (1 + r)s + y2a. Derive the household’s intertemporal budget constraint.b. Assume that the preferences of the household can be represented by a log utility...
