18.7 Reserve Currencies in the World Monetary System
1) Briefly describe two systems for fixing the exchange rates of all currencies against each other
and the time periods in which they were used.
2) This question concerns the mechanism of a reserve currency standard.
Two countries, X and Y, have two currencies, x and y, fixed to the reserve currency, the U.S.
dollar. Suppose the exchange rate between x and the U.S. dollar is 3x per dollar. Suppose the
exchange rate between y and the U.S. dollar is 5y per dollar. Explain (using numbers) the
mechanism if the x-y exchange rate was 0.5 x per y.
3) This question concerns the mechanism of a reserve currency standard.
Two countries, X and Y, have two currencies, x and y, fixed to the reserve currency, the U.S.
dollar. Suppose the exchange rate between x and the U.S. dollar is 3x per dollar. Suppose the
exchange rate between y and the U.S. dollar is 5y per dollar. Explain (using numbers) the
mechanism if the x-y exchange rate was 0.8 x per y.

macroeconomic stabilization. In particular, explain the result if that country doubled its domestic
money supply.

Answer:
10) Assume that initially, the risk premium, ρ = 0 and that the domestic and foreign interest rates

ρ =

(a) B - A = -.01/
(b) B - A = .01/
(c) B - A = .03/
