Consider an economy with two individuals, Ann and Bob and two goods x and y. Ann's initial endowment is (50, 20) and Bob's initial endowment is (20,50). Ann's utility function is u(x,y)=xy and Bob's utility function is up = x xy. (1) (2.5 points ] Draw the Edgeworth box and show the initial endowment, the indifference curves for both individuals associated with their endowments. (2) [12.5 points ] Is the initial endowment Pareto efficient? Why?Determine the contract curve.
