Exchange Rate Policy and Hyperinflation
This paper studies the problem of foreign exchange policy emphasizing the portfolio and liquidity services of domestic and foreign currency. It shows that the impact of increasing borrowing to finance deficits requires a higher rate of devaluation for the domestic currency. The analysis provides a generalization of the Unpleasant Monetarist Arithmetic of Sargent and Wallace for an open economy and with unique solutions on both sides of the Laffer curve.
