8.6.1

6. Suppose absolute PPP holds and prices are perfectly flexible (ie. absolute PPP holds even in the short-run). a) Calculate the equilibrium exchange rate Eus$7 (L.e. dollars per euro) based on the information below: Real money demand in the United States is given by L$ = 1.2Yus-2R$ Real money demand in the Eurozone is given by L = 3YEur - 4R Where Yx gives national income in country/region x and Rx is the interest rate for currency x. The specific values, including also for nominal money supplies, are as in the following table: Yeur = 18 R = 1 Yus = 20 R$ = 2 Nominal Money Supplies Msus = 6,000 Meur = 10,000 b) Now assume that there is a sudden increase in productivity that increases national income in the United States to 23.333 (everything else stays the same). Recalculate the equilibrium exchange rate Eus$7 (to one decimal point is fine) c) Did the dollar appreciate or depreciate in part b)? Explain your result. 6.
