Suppose we have an economy with two types of households: Minnesotans [M] and Wisconsinites [W]. Both types live for two periods and have the same utility function and discount rates ,3 E {0,1}, but may diiTer in their endowments and consumption allocation. There is an equal population of each type. The market clearing condition for the rst period is end + cw 2 3m + yw, and likewise similar for the second period. There are no rms or government. The utility maximization problem for a household of type 1' E {1141: Hf} is: Hmeesaa-hed} -.'.'.' IE1 subject to _ a __ e '*+1+-r_i'"'+1+l~ 'roblems: {a} Dene the competitive equilibrium in this economy. Make sure to specify all the relevant problems and conditions. For households: you may write out each type's problem seperately or write a single maximization problem indexed by t. {b} Solve for the intertemporal Euler equation for a household of type 1i. {Set up the Lagrangian for a household, nd the F003, and then comb-inc them to get an eapreeeton about the Marginal Rate of Suhst-itution between. goods today and goods tolrnonr-a-nruyI [c] Solve for consumption allocations in period 1 and 2 for household of type t as [mictions of their income [gt-,yg} and prices {r} {d} Suppose that the endowments are given by: (gm.

(e) Substitute the market clearing interest rate back into your consumption functions from part {c} and solve for the equilibrium allocations. Which household is borrowing in the rst period and which household is saving? What is the economic intuition for this? [f] Why does household M have higher consumption in each period? Explain
