Optimum Currency Pegs for Latin America
分析1950-1979年拉丁美洲18国的通胀与增长数据，发现钉住美元的国家通胀低且稳定，反之则高且不稳定，为选择汇率制度提供依据。
THE POSTWAR ECONOMIC RECORD of Latin America from 1950 to 1979 is a mixed one.

Monetary growth rates exhibit the same pattern: low and stable in some countries, high and unstable in others. Real growth rates range from lows of 1 percent in Uruguay to highs of 9 percent in Brazil and Mexico. For the eighteen Latin American countries as a whole, the inflation rate since 1950 has averaged 21 percent with a standard deviation of 30 percent, monetary growth rates 29 percent (S.D. of 25 percent), and real growth rates 5 percent (S.D. of 2 percent). One striking fact emerges from a cursory examination of this historical record: countries that peg to the U.S . dollar experience low and stable inflation rates, while those that do not exhibit high and unstable inflation rates. The choice to peg to the dollar is, simultaneously, a decision not to inflate more than the United States. It is a clear signal regarding the future supply of local money. Similarly, a decision to inflate more than the United States is, simultaneously, a choice not to have a fixed
