In the aftermath of the Asian/global financial crises of 1997-98, how should emerging markets now structure their exchange rate systems to prevent new crises from occurring? This study challenges current orthodoxy by advocating the revival of intermediate exchange rate regimes. In so doing, Williamson presents a reasoned challenge to the new prevailing attitude which claims that all countries involved in the international capital markets need to polarize to one of the extreme regimes (to a fixed rate with either a currency board or dollarization, or to a lightly-managed float). He concludes that although there is some truth in the allegation that intermediate regimes are vulnerable to speculative crises, they still offer offsetting advantages. He also contends that it would be possible to redesign them to be more flexible so as to reduce their vulnerability to crises.

This paper investigates the effects of the adoption of inflation targeting (IT) on the choice of exchange rate regime in emerging markets (EMs), conditional on certain macroeconomic conditions. Using a large sample of EMs and after controlling for the selection bias associated with the adoption of IT, we find that IT countries on average have a relatively more flexible exchange rate regime than other EMs. However, the flexibility of the exchange rate regime shows strong heterogeneity among IT countries depending on their degree of openness and exposure to FX risks. Moreover, we find that the marginal effect of IT adoption on the exchange rate flexibility increases with the duration of the IT regime in place, and with the propensity scores to adopt it.

This paper compares the impact of shocks to U.S. interest rates and emerging market bond spreads on domestic interest rates and exchange rates across several emerging market economies with different exchange rate regimes. Consistent with conventional priors, the results indicate that interest rates in Hong Kong react much more to U.S. interest rate shocks and shocks to international risk premia than interest rates in Singapore. The results are less clearcut in the comparison of Argentina and Mexico: While interest rates (and the exchange rate) in Mexico seem to react less to U.S. interest rate shocks, they react about the same to bond spread shocks, in addition to a significant impact on the exchange rate.

Reviews some empirical evidence on the recent performance of alternative exchange rate arrangements in emerging markets. Examines the concrete circumstances under which either polar regime should be adopted. Studies how to make flexibility work in practice, with special attention to inflation targets and alternativie monetary policy rules. Focuses on the possible role of capital controls as a complementary policy.

We characterize a country's exchange rate regime by how its central bank channels a capital account shock across three variables: exchange depreciation, interest rates, and international reserve flows. Structural vector autoregression estimates for Brazil, Mexico, and Turkey reveal such responses, both contemporaneously and over time. Capital account shocks are further shown to affect output growth and inflation. The nature and magnitude of these effects may depend on the exchange rate regime.

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.

Most of the literature on exchange rate regimes has focused on the developed countries. Since the recent crises in emerging markets, however, attention has shifted to the choice of exchange rate regimes for developing countries, especially those that are more integrated into the world capital markets. In Too Sensational, W. Max Corden presents a systematic and accessible overview of the choice of exchange rate regimes. Reviewing many types of regimes, he shows how the choice of an exchange rate regime is related to both fiscal policy and trade policy. Building on the theory of optimum currency areas, Corden develops an analytic framework of three approaches (nominal anchor, real targets, and exchange rate stability) and three polar exchange rate regimes (absolutely fixed, pure floating, and fixed but adjustable). He considers all other regimes to be mixtures of two or three of the polar regimes. Beginning with theory and later turning to case studies of countries in Asia, Europe, and Latin America, Corden focuses on how economies react to negative and positive shocks under various exchange rate regimes. He examines in particular the Asian and Latin American currency crises of the 1990s. He concludes that although "too sensational" crises have discredited fixed but adjustable regimes, the extremes of absolutely fixed regimes or pure floating regimes need not be chosen.
