We develop a framework for studying the choice of exchange rate regime in an open economy where the local currency is vulnerable to speculative attacks. The framework makes it possible to study, for the first time, the strategic interaction between the ex ante choice of regime and the probability of ex post currency attacks. The optimal regime is determined by a policymaker who trades off the loss from nominal exchange rate uncertainty against the cost of maintaining a given regime. This cost is affected in turn by the likelihood of a speculative attack. Searching for the optimal regime within the class of exchange rate bands, we show that the optimal regime is either a peg (a zero-width band), a free float (an infinite-width band), or a non-degenerate finite-width band. Our framework generates several novel predictions and shows that when the endogeneity of the exchange rate regime is recognized explicitly, conventional wisdom may be reversed. For instance, the imposition of a Tobin tax, by inducing policymakers to set less flexible regimes, may raise the likelihood of speculative attacks.

How will free trade affect monetary policy and exchange rate regime choices in the Americas? While the European Union illustrates how the creation of an integrated market in goods and services can enhance monetary cooperation and integration, it is not clear that Europe's experience translates to Latin America, where the political circumstances are different. We try to understand whether the monetary consequences of existing regional trade agreements, including but not limited to the European Union, mainly reflect spillovers from trade integration, or whether observed outcomes have been mainly about politics. Our results incline us toward the latter interpretation, leaving us pessimistic about the basis for deeper monetary cooperation. If exchange rate volatility is to be tamed, then the more widespread adoption of inflation targeting, which we find to be associated with a significant reduction in bilateral exchange rate volatility, may be the most promising path.
