This paper investigates the potential impacts of the degree of divergence in open macroeconomic policies in the context of the trilemma hypothesis. Using an index that measures the relative policy divergence among the three trilemma policy choices, namely monetary independence, exchange rate...

This paper investigates the factors explaining exchange market pressures (EMP) and the hoarding and use of international reserves (IR) by emerging markets during the 2000s, as the Great Moderation turned to the 2008-9 global crisis and great recession. According to our results, both financial...

Emerging economies are prone to crises triggered by external shocks. During these crises, should the central bank stabilize the currency or domestic interest rates? If the choice is outside the central bank's control, as in a currency board, are there good policy substitutes? We argue that these...

This paper outlines a set of financial policies that can help make financial crises less likely in emerging market countries. To justify these policies, the paper first explains what a financial crisis is, the factors that promote a financial crisis and the dynamics of a financial crisis. It...

We model sudden stops in a small open economy as rare discrete events precipitated by increases in the world risk-free rate. When external debt is large, the model exhibits multiple equilibria, one where external debt and consumption remain high, and one with a collapse in external debt and...

This paper develops an open economy model in which financial intermediation is subject to occasionally binding collateral constraints, and uses the model to study unconventional policies such as credit facilities and foreign exchange intervention. The model highlights the interaction between the...

The optimal choice of a monetary policy instrument depends on how tight and transparent the available instruments are and on whether policymakers can commit to future policies. Tightness is always desirable; transparency is only if policymakers cannot commit. Interest rates, which can be made...
