We study a wide range of hybrid inflation-targeting (IT) and managed exchange rate regimes, analyzing their implications for inflation, output and the exchange rate in the presence of various domestic and external shocks. To this end, we develop an open economy new-Keynesian model featuring...

The global financial crisis in 2008 and 2009 renewed interest for the role of international reserves in preventing and mitigating currency crises. The findings usually support the view that higher (or excess) reserves provided insurance against currency instability, which is considered as a good...

Some emerging economies have recently experienced large government surpluses and accelerating foreign exchange reserve accumulation far in excess of what would be implied by the literature on optimal reserves. China in particular has repeatedly stressed that there may be an upper limit to how...

The issue of the appropriate exchange rate regime for individual countries has been perennially lively, and the role played by international capital flows and domestic financial systems in determining the performance of these regimes has gained prominence in the policy debate. Using recent...

Upon entry into the European Union, countries become members of the Economic and Monetary Union (EMU), with a derogation from adopting the euro as their currency (that is, each country joining the EU commits to replace its national currency with the euro, but can choose when to request...

Since the turn of the century, aid flows to Africa have increased on average and become more volatile. As a result, policymakers, particularly in post-stabilization countries where inflation has only recently been brought under control, have been increasingly preoccupied with how best to deploy...

We focus on the management of highly persistent shocks to aid flows, including PRSP-related increases in net inflows, in three “post-stabilization.” African economies with de jure flexible exchange rates. Such shocks have beneficent long-run effects, but when currency substitution is high...

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...

This paper analyzes a small open economy model under inflation targeting. It shows why such a monetary regime is vulnerable to speculative attacks that take place over a short period rather than instantaneously. The speed at which the regime collapses, and the extent of reserve losses, are...
