(A TNT Endowment Economy) Consider an economy populated by identical households with preferences described by the utility function lnC1 lnC2 where Ct denotes consumption in period t = 1, 2. Suppose that consumption is a composite of tradable and nontradable consumption given by Ct = pCT t CN t , where CT t and CN t denote consumption of tradable and nontradable goods in period t = 1, 2. Households receive 1 unit of tradable goods in period 1 and 2 units in period 2 (QT 1 = 1 and QT 2 = 2) and 4 units of nontradables in period 1 and 3 in period 2 (QN 1 = 4 and QN 2 = 3). Suppose further that the country has free capital mobility and that the world interest rate is nil (r = 0)
