This paper argues that economic structure is a robust determinant of the OECD business cycle. Countries that share similar manufacturing sectors are shown to display more synchronized business cycles. Interestingly, the well-established rule of trade impacting on rich countries' business cycles...

This paper studies the evolution of sectoral concentration in relation to the level of per capita income. We show that various measures of sectoral concentration follow a U-shaped pattern across a wide variety of data sources: countries first diversify, in the sense that economic activity is...

Fluctuations in GDP are more synchronized internationally than fluctuations in consumption, and they remain so even between financially-integrated economies, where the ranking should in theory be the reverse. This Paper shows this happens because correlations in GDP fluctuations rise with...

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 many such small...

I revisit the relationship between growth and volatility in two different disaggregated datasets. I confirm that growth and volatility are negatively related across countries, but show that the relation reverses itself across sectors. This phenomenon, sometimes called the ‘Simpson’s...

This Paper studies the evolution of sectoral labour concentration in relation to the level of per capita income. We show that various measures of sectoral concentration follow a U-shaped pattern across a wide variety of data sources: countries first diversify, in the sense that labour is spread...

This paper uses monthly data on industrial production to estimate the distribution of international business cycle correlations since the 1980s, with a focus on the current turmoil. The degree of international correlation in national business cycles since the end of 2008 is unprecedented in...

We show that since 1994, branching deregulations in the U.S have Âsignificantly 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 show the importance of a dynamic aggregation bias in accounting for the PPP puzzle. We prove that established time-series and panel methods substantially exaggerate the persistence of real exchange rates because of heterogeneity in the dynamics of disaggregated relative prices. When...

The New Keynesian Phillips Curve is at the center of two raging empirical debates. First, how can purely forward looking pricing account for the observed persistence in aggregate inflation. Second, price-setting responds to movements in marginal costs, which should therefore be the driving force...
