It has long been recognized that business cycle comovement is greater between countries that trade intensively with one another. Surprisingly, no one has previously examined the relationship between trade intensity and comovement of shocks to the trend level of output. Contrary to the result for...

The overriding practical problem now is the tension between the global financial and market system and the national political and power structures. The main analytical short-coming lies in the failure to incorporate financial frictions, especially default, into our macro-economic models. Neither...

Cyclical fluctuations in nominal variables--aggregate price levels and nominal interest rates--are documented to be substantially more synchronized across countries than cyclical fluctuations in real output. A transparent mechanism that can account for this striking feature of the nominal...

This paper analyzes the evolution of the degree of global cyclical interdependence over the period 1960-2005. We categorize the 106 countries in our sample into three groups -- industrial countries, emerging markets, and other developing economies. Using a dynamic factor model, we then decompose...

A large body of cross-country empirical evidence identifies monetary policy and trade integration as key determinants of business cycle co-movement. Partially consistent with this, many argue that the re-emergence of the gold standard allowed for the global transmission of a deflationary shock...

Two separate narratives have emerged in the wake of the Global Financial Crisis. One interpretation speaks of private financial excess and the key role of the banking system in leveraging and deleveraging the economy. The other emphasizes the public sector balance sheet over the private and...

Perhaps because health care is a local service sector, health economists have paid little attention to international linkages between domestic health care economies. However, the growth in domestic health care sectors is often attributed to medical innovations whose returns are earned worldwide....

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...

Activities of international banks have been at the core of discussions on the causes and effects of the international financial crisis. Yet we know little about the actual magnitudes and mechanisms for transmission of liquidity shocks through international banks, including the reasons for...

Basic economic theory identifies a number of efficiency gains that derive from international capital mobility. But just as free trade in goods, there is no guarantee that capital mobility makes everyone better off. Consequently, capital mobility may be politically unsustainable even though it...
