This volume contains the papers presented and comments made at two conferences on the controversial subject of greater flexibility of exchange rates. The first of the conferences was held at Oyster Bay, New York, early in 1969, the second at Bürgenstock, Switzerland, in the summer of 1969. One half of the 40 conferees were academic economists, the others were practitioners of the foreign exchange markets, mostly bankers and a few executives of international business firms. Both the opposition to greater flexibility of exchange rates and the advocacy of more flexible systems are represented in these papers. The contrast between fixed or jumping exchange rates and gliding exchange rates is clearly described and the various systems of increased flexibility, such as the "wider band" and the "crawling peg," are explained and examined. Originally published in 1970. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
