A central result in international macroeconomics is that a government cannot simultaneously opt for open financial markets, fixed exchange rates, and monetary autonomy; rather, it is constrained to choosing no more than two of these three. In the wake of the Great Recession, however, there has...

It has been a well-known puzzle why the yen has not been used more in trade invoicing among Japanese exporters. Despite the yen's status as an only fully convertible currency in Asia, two patterns stand out as puzzling features of an excessively small share of yen invoicing: First, a strong...

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 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...

This paper develops a new technique for measuring changes in the degree of capital mobility confronting a developing country that has restrictions on capital flows and official ceilings on domestic interest rates. Because such official controls rule out the use of traditional interest rate...

This paper re-examines the effect of devaluation under capital-account restrictions, adding to traditional formulations the seemingly minor (but realistic) assumption that central-bank reserves earn interest. The extra assumption has important implications. In an intertemporal model, devaluation...

A new theoretical literature studies the use of capital controls to prevent financial crises in models in which pecuniary externalities justify government intervention. Within the same theoretical framework, we show that when ex-post policies such as defending the exchange rate can contain or...

A salient characteristic of sovereign defaults is that they are typically accompanied by large devaluations. This paper presents new evidence of this empirical regularity known as the Twin Ds and proposes a model that rationalizes it as an optimal policy outcome. The model combines limited...
