Consider the Ricardian model with two economies (Mexico and the U.S.A.) and two commodities (goods and services). The marginal products of labor for each commodity are as follows: Services and Goods for Mexico MPL*_S = 1/4 for services and for goods it is MPL*_G = 1/2 for U.S.A. the services is MPL_S = 1 and MPL_G = 1 is the goods. Assume the two economies are closed and prices of Services are: pS = $2, and p*S = 12 pesos. (a) Calculate the qaurterly price of Goods in both countries: pG, and p*G.
