What are the drivers of business cycle fluctuations? And how many are there? Bydocumenting strong and predictable co-movement of real variables during the business cyclein a sample of advanced economies, we argue that most business cycle fluctuations aredriven by one major factor. The positive...

In the last few decades, real GDP growth and investment in advanced countries have declined in tandem. This slowdown was not the result of weak demand (there has been no shift along the Okun curve), but of a decline in potential output growth (which has shifted the Okun curve to the left). We...

Using panel data for a large number of countries, we find that economic contractions are not followed by offsetting fast recoveries. Trend output lost is not regained, on average. Wars, crises, and other negative shocks lead to absolute divergence and lower long-run growth, whereas we find...

We examine the properties of house price fluctuations across 18 advanced economies over the past 40 years. We ask two specific questions: First, how synchronized are housing cycles across these countries? Second, what are the main shocks driving movements in global house prices? To address these...

Both global and regional economic linkages have strengthened substantially over the past quarter century. We employ a dynamic factor model to analyze the implications of these linkages for the evolution of global and regional business cycles. Our model allows us to assess the roles played by the...

This paper examines the impact of international financial integration on macroeconomic volatility in a large group of industrial and developing economies over the period 1960-99. We report two major results: First, while the volatility of output growth has, on average, declined in the 1990s...

We compare business cycle fluctuations in Sub-Saharan African (SSA) countries vis-à-vis the rest of the world. Our main results are as follows: (i) African economies stand out by their macroeconomic volatility, which is is reflected in the volatility of output and other macro variables; (ii)...

This paper studies changes in the transmission of common versus sectoral idiosyncraticshocks across different U.S. nonfarm business sectors during the Great Recession, andevaluates the cross-sectoral spillovers. Shocks are identified by dynamic factor methods. Wefind that the Great Recession is...

This paper shows that remittance flows significantly increase the business cycle synchronization between remittance-recipient countries and the rest of the world. Using both aggregate and bilateral remittances data in a panel data setting, the study demonstrates that this effect is robust and...
