The literature lacks consensus on the role of currency regimes in explaining external competitiveness. Countries not only differ in terms of currency regimes, but can also have different institutional arrangements, namely trade agreements and inflation targeting (IT) frameworks in addition to the overall quality of governance. Hence, using the real effective exchange rate and by covering 35 developing countries over the period 1975–2014, we investigate the role of currency regimes in explaining the degree of misalignment while considering institutional factors. First, we find that intermediate regimes limit the currency misalignment with greater financial openness (FO). Second, non-reciprocal preferential trade agreements improve price competitiveness, whereas free trade and reciprocal ones can only be beneficial with a higher degree of FO. Third, misalignments in fixed regimes decline in the presence of stronger institutions or in countries with an IT type of monetary policy framework. The above results remain robust to alternative specifications.

The paper analyses exchange rate regimes implemented by the major Latin American (LA) countries since the 1950s, with special attention to the period beginning in the 1970s. The aim is to evaluate the relationship between exchange rate regimes and macroeconomic performance. After an overview of the main trends followed by the major LA countries over the last 60 years, the paper focusses on regimes that were implemented (1) with stabilisation purposes (nominal anchor) and (2) with the aim of targeting competitive and stable real exchange rates. These sections analyse in greater detail some important links between exchange rate regimes and macroeconomic performance. The paper closes with an assessment of the experiences with exchange rate regimes in LA.

We argue that a fixed exchange rate can be an optimal choice even if a policy maker could commit to the first-best monetary policy whenever the private sector's beliefs reflect incomplete information about the policy maker's dependability. This model implies that joining a currency area may be optimal for its impact not on the behavior of the policy maker, but on the beliefs of the private sector. Monetary policies are evaluated using a new Keynesian model of a small open economy solved under imperfect policy credibility. We quantify the minimum distance between announced policy and the private sector's beliefs that is necessary for a peg to perform better than an independent monetary policy when the policy maker can commit to the first-best policy.

This paper makes an empirical contribution to discussion of the optimal exchange rate regime. Using a new dataset for Central American countries, we compare the dynamics of the real exchange rate (RER) between dollarised and non-dollarised countries. Our results show that the two dollarised countries in the region, El Salvador and Panama, are quite different in terms of RER dynamics. In El Salvador the RER spends more time away from its equilibrium level than in the non-dollarised countries in the region, while the contrary is true for Panama. We also find that inflation persistence is similar in El Salvador to the other countries, but smaller in Panama. This leads us to the conclusion that some degree of exchange rate flexibility helps countries to have a more aligned RER. Nevertheless, a long-lived, highly credible dollarised economy, like Panama, can reduce inflation persistence to such an extent that RER misalignments are in fact less frequent than in countries with more flexible exchange rate regimes.
