Sercu and Uppal examine volatility of exchange rates in the context of dynamic general equilibrium models.

The member countries of the International Monetary Fund collaborate to try to assure orderly exchange arrangements and promote a stable system of exchange rates, recognizing that the essential purpose of the international monetary system is to facilitate the exchange of goods, services, and capital, and to sustain sound economic growth. The paper reviews the stability of the overall system of exchange rates by examining macroeconomic performance (inflation, growth, crises) under alternative exchange rate regimes; implications of exchange rate regime choice for interaction with the rest of the system (external adjustment, trade integration, capital flows); and potential sources of stress to the international monetary system.

The effect of exchange rate volatility on trade flows was examined by a 1984 IMF study on G-7 countries. Over the past two decades, many developments in the world economy, such as the currency crises in the 1990s and increasing cross-border capital flows, may have exacerbated exchange rate volatility, while others, such as a deepening of the market in foreign exchange hedging instruments, may have reduced the impact of volatility on trade flows. Using recent advances in the economic theories on trade and in statistical methodologies, this paper revisits this important issue by taking into account these new developments and examining their effects on developing and transition economies, as well as on developed countries.

This paper identifies the institutional and operational requisites for transitions to floating exchange rate regimes. In particular, it explores key issues underlying the transition, including developing a deep and liquid foreign exchange market, formulating intervention policies consistent with the new regime, establishing an alternative nominal anchor in the context of a new monetary policy framework, and building the capacity of market participants to manage exchange rate risks and of supervisory authorities to regulate and monitor them. It also assesses the factors that influence the pace of exit and the appropriate sequencing of exchange rate flexibility and capital account liberalization.

Using recent advances in the classification of exchange rate regimes, this paper finds no support for the popular bipolar view that countries will tend over time to move to the polar extremes of free float or rigid peg. Rather, intermediate regimes have shown remarkable durability. The analysis suggests that as economies mature, the value of exchange rate flexibility rises. For countries at a relatively early stage of financial development and integration, fixed or relatively rigid regimes appear to offer some anti-inflation credibility gain without compromising growth objectives. As countries develop economically and institutionally, there appear to be considerable benefits to more flexible regimes. For developed countries that are not in a currency union, relatively flexible exchange rate regimes appear to offer higher growth without any cost in credibility.
