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...

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...

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...

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...

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...

The purpose of this paper is to explain the reluctance of developing countries to open up their capital market to foreigners, and the conditions inducing an emerging market economy to switch its policies. We consider an economy characterized initially by a one-sided openness to the capital...

We propose a theory of endogenous composition of capital flows that highlights two asymmetries between international equity and debt financing. In our model, poor institutional quality leads to an inefficiently low share of equity financing as well as an inefficiently high volume of total...

The literature on capital controls has (at least) four very serious apples-to-oranges problems: (i) There is not unified theoretical framework to analyze the macroeconomic consequences of controls; (ii) there is significant heterogeneity across countries and time in the control measures...

We extend our earlier work, focusing on the links between capital account liberalization, legal and institutional development, and financial development, especially that in equity markets. In a panel data analysis encompassing 108 countries and twenty years ranging from 1980 to 2000, we explore...
