The paper investigates the determinants of business cycles synchronization across regions. It uses both international and intranational data to evaluate the linkages between trade in goods, trade in financial assets, specialization and business cycles synchronization using a system of...

In this paper, we identify the groups of countries where international risk-sharing opportunities are most attractive. We show that the bulk of risk-sharing gains can be achieved in groups consisting of as few as seven members, and that further marginal benefits quickly become negligible. For...

In a recent paper, Frankel and Rose (1998) documented endogenous effects of a monetary union, whereby costs and benefits of the union evolve after its implementation. This paper questions their findings on three grounds. First, their main result that trading partners display relatively more...

Estimates of the elasticity of substitution between domestic and foreign varieties are small in macroeconomic data, but substantially larger in disaggregated microeconomic studies. This may be an artifact of heterogeneity. We use disaggregated multilateral trade data to structurally identify...

I use monthly data on industrial production to estimate the distribution of international business cycle correlations since the 1980's, with focus on the current turmoil. The degree of international correlation in national business cycles since the end of 2008 is unprecedented in three decades....

We document that the deregulation of bank branching restrictions in the United States triggered a reallocation across sectors, with end effects on state-level volatility. The change cannot be explained simply by shifts in sector-level returns and volatility. A reallocation effect is at play,...

We show that since 1994, branching deregulations in the U.S have significantly affected the supply of mortgage credit, and ultimately house prices. With deregulation, the number and volume of originated mortgage loans increase, while denial rates fall. But the deregulation has no effect on a...

We revisit the debt overhang question. We first use non-parametric techniques to isolate a panel of countries on the downward sloping section of a debt Laffer curve. In particular, overhang countries are ones where a threshold level of debt is reached in sample, beyond which (initial) debt ends...

We estimate the aggregate export and import price elasticities implied by a Constant Elasticity of Substitution (CES) demand system, for more than 30 countries at various stages of development. Trade elasticities are given by weighted averages of sector-specific elasticities of substitution,...

Estimates of the elasticity of substitution between domestic and foreign varieties are small in macroeconomic data, and substantially larger in disaggregated studies. This may be an artifact of heterogeneity. We use disaggregated multilateral trade data to structurally identify elasticities of...
