Problem 8 (4+4-I-4=12 points) Suppose in a market, two consumers (A and B) given in the previous Problem 7 exchange two goods (Good 1 and Good 2) when their endowments are (\"A = (wtwgl) = (109 15) w\" = (um?) = (10.10). The Walrasian demands for the consumers A and B are l . Item = wi + 3%\"; i i 2P! i 2 i at? (p,w ) = 37'2\"] + is): for i = A, B. (:1) Calculate the market excess demand for the rst good. (b) Compute the Walrasinn equilibrium price ratio. (0) Compute the Walrasian equilibrium payoff vector
