Consider. U1 (21, y1) = 5(x191 )3+ 12 U2(X2, y2) = 3lnx2 + 25lny2 + 10 W1 = (7,3) and W2 = (4, 6) a. Characterize the Pareto efficient allocations and contract curve b. Which allocations are in the core (5 points)? c. Find the Competitive/ Walrasian equilibrium for this problem 5 d. Is the allocation found in c in the core? Why? (5 points)
