PREFACE: EXCHANGE RATES, CAPITAL FLOWS, AND MONETARY POLICY IN A CHANGING WORLD ECONOMY The dramatic growth of international capital flows has provided unprecedented opportunities and risks in emerging markets. Investors, policymakers, central bankers, and other practitioners who interact in these markets participated in a lively exchange of ideas about these risks and opportunities during a Federal Reserve Bank of Dallas Conference on September 14-15, 1995. Exchange Rates, Capital Flows, and Monetary Policy in a Changing World Economy is the proceedings of that conference. In Part I, "Exchange Rates and Monetary Policy," Jeffrey A. Frankel concludes that the system is broken "in the sense that it is not working in the perfect, idealized way that our theories say." He cautions against radical reforms but says "some intelligent intervention from time to time cannot hurt and sometimes can help." Leonardo Auernheimer and Steve Hanke offer comments. Part II consists of Sebastian Edwards', "Optimal Exchange Rate Policy for Stabilizing Inflation in Developing Countries," with discussion from Graciela Kaminsky and John Welch. Edwards focuses on the use of exchange rates as stabilization devices in anti-inflationary programs. He looks for determinants of success and considers dangers and challenges of such policies. In Part ill, Vittorio Corbo discusses his work with Patricio Rojas of Chile's Central Bank, "Exchange Rate Volatility, Investment, and Growth: Some New Evidence." Corbo examines how macroeconomic uncertainty about the inflation rate and the real exchange rate affect economic growth through two mechanisms: vii Vlll EXCHANGE RATES, CAPITAL FLOWS, AND MONETARY POLICY the rate of investment and the overall level of efficiency. Commentary is from David Gould and Liliana Rojas-Suarez. In Part IV, "Speculative Attacks," Peter M. Garber reviews theories about speculative attacks and considers what happens in the days or hours before a fixed-exchange-rate regime collapses. He relates his comments to two recent cases, the collapse of the European Exchange Rate Mechanism (ERM) in 1992 and 1993 and the collapse of the Mexican peso at the end of 1994. Discussion from Guillermo Mondino and Miguel Savastano follows. Part V is Alan S. Blinder's assessment: "The Role of the Dollar as an Inter national Currency." Although Blinder finds many claims about the decline of the dollar as a reserve currency, he concludes that they are remarkably undisciplined by facts. "Wherever we have data," Blinder says, the message seems to be more or less the same: the dollar is still unquestionably the world's dominant international currency by any conceivable definition. But its preeminent position is eroding slowly, as mainly the Deutsche mark and, secondarily, the yen move up on the pecking order. In Part VI, "International Capital Flows: Direct vs. Portfolio Investment," Michael P. Dooley challenges conventional wisdom about capital flows, control of capital flows, and what countries might hope to accomplish with capital controls. "Both lenders and the borrowers often see international capital flows as a welfare-reducing phenomenon," Dooley says. But he finds that the motivation for capital flows derives from government policy: the size of the capital inflow will be a function of the credibility of the insurance fund. Thus, policy reforms, particularly fiscal reforms, generate capital inflows, but the size of the capital inflow will be just sufficient to exhaust the insurance fund, he says. "The only way, in my view, to break the insurance chain and discourage these kinds of capital inflows is to introduce uncertainty in the exchange rate and ... make the private sector investor bear the risk of that investment," Dooley concludes. AgustIn Carstens and Edwin M. Truman offer comments. Part VII, "Central Bank Coordination in the Midst of Exchange Rate Instabil ity," is a panel discussion by Miguel Urrutia, John W. Crow, Ricardo Hausmann, and Allan Meltzer. This conference would not have been possible without the efforts of many people. We wish to thank Bob McTeer, Harvey Rosenblum, Sherry Kiser, KaSandra Goulding, Agnes Mitchell, Daniel Sanchez, and all the contributors, who made this conference possible. We also thank our editorial staff-Anne Coursey, Rhonda Harris, Monica Reeves, and Kathy Thacker. William C. Gruben David M. Gould Carlos E. Zarazaga ABOUT THE PARTICIPANTS Alan S.

Part I EXCHANGE RATES AND MONETARY POLICY The enormous volatility of floating exchange rates has led to a call for limits on exchange rate fluctuations. An increasing number of countries have begun to question the benefits of floating exchange rates. Can central banks limit exchange rate fluctuations, and are there benefits from doing so?
