Perfect Competition and Fixed Prices: Exercises Exercise 1 1. A representative …rm produces the unique homogeneous …nal good using the technology Y = N , with Y the output and N the employment. Note W the nominal wage and P the price of the …nal good. Determine the optimal behavior of this producer. 2. A representative consumer has preferences de…ned on consumption C, real money demand M=P and leisure H N , with H > 0 the time endowment. His utility function is de…ned by: C 0:2 (M=P )0:7 + 0:1 ln(H
N)
S/He has the stock of money M0 > 0 as endowment, receives the pro…ts of the …rm and need to pay a lump-sum tax T . (i) Write the budget constraint. (ii) Determine the optimal behavior of the consumer. 3. Let G be the level of public spending. Using the balanced budget of the government P G = T , determine the equilibrium, especially the level of employment. 4. Determine the e¤ect of an increase of G on N . Give an economic interpretation.

Exercise 2 We introduce the following notations: N d the labor demand, N s the labor supply, Y d the demand of product, Y s the supply of product, P the price of good, W the nominal wage, and M0 > 0 the stock of money. We assume that: 1 P ; N s = 1=3 W 1 P 1 M0 ; Ys = Yd = P W

Determine the conditions such that one obtains keynesian unemployment and represent it on a graph. 3. Determine the conditions such that one obtains classical unemployment and represent it on a graph.
