We revisit the issue of fiscal procyclicality in commodity-rich nations -commodity republics in the nomenclature of this paper. Since commodity prices are plausibly a main driver of fiscal policy outcomes in these countries, we focus on the behavior of fiscal variables across the commodity...

This paper looks at the short history of the Eurozone through the lens of an evolutionary approach to forming new institutions. The euro has operated as a currency without a state, under the dominance of Germany. This has so far allowed the euro to achieve a number of design objectives, and this...

We test the hypothesis that net foreign asset positions are consistent with external solvency and examine the dynamics of external adjustment using data for 50 countries over the 1970-2006 period. Our analysis adapts Bohn's (2007) error-correction reaction function approach--which tests for a...

This paper addresses the issue of the optimal stock of international reserves in terms of a statistical model in which reserves affect both the probability of a Sudden Stop-as well as associated output costs-by reducing the balance-sheet effects of liability dollarization. Optimal reserves are...

We lay down a standard macroeconomic model of a small open economy with a fixed exchange rate and study optimal capital controls (defined as maximizing the utility of a representative household). We provide sharp analytical and numerical characterizations for a variety of shocks. We find that...

The interaction between credit frictions, financial innovation, and a switch from optimistic to pessimistic beliefs played a central role in the 2008 financial crisis. This paper develops a quantitative general equilibrium framework in which this interaction drives the financial amplification...

Virtually all economies experience recurrent fluctuations in economic activity that persist for periods of several quarters to several years. Further, there is a definite tendency for the business cycles of developed countries to move together--there is a world component to business cycles. This...

This paper shows how changes in the volatility of the real interest rate at which small open emerging economies borrow have a quantitatively important effect on real variables like output, consumption, investment, and hours worked. To motivate our investigation, we document the strong evidence...

There are two main forces behind the large U.S. current account deficits. First, an increase in the U.S. demand for foreign goods. Second, an increase in the foreign demand for U.S. assets. Both forces have contributed to steadily increasing current account deficits since the mid--1990s. This...

Recent studies have emphasized the role of valuation effects due to exchange rate movements in easing the process of adjustment of the external balance of a country. This paper asks to what extent valuation effects are desirable from a global perspective as a mean to achieve an efficient...
