Using disaggregated data for the United States, this paper explores the effects of the variability of fiscal and monetary policy shocks. Higher variability of government spending shocks around a steady-state growth trend results, on average, in a decline in aggregate demand growth and inflation,...

In the last decade, over half of the EU countries in the euro area or with currencies pegged to the euro were hit by large risk premium shocks. Previous papers have focused on the impact of these shocks on demand. This paper, by contrast, focuses on the impact on supply. We show that risk...

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...

This paper analyzes the sources of output and unemployment dynamics in the world economy during the Great Recession. This analysis is based on a panel unobserved components model of the world economy, disaggregated into its fifteen largest national economies. We find that excess supply pressure...

While the COVID-19 pandemic is affecting all countries, output losses vary considerably across countries. We provide a first analysis of robust determinants of observed initial output losses using model-averaging techniques-Weighted Average Least Squares and Bayesian Model Averaging. The results...

This paper uses a global input-output framework to quantify US and EU demand spillovers and the elasticity of world trade to GDP during the global recession of 2008-2009. We find that 20-30 percent of the decline in the US and EU demand was borne by foreign countries, with NAFTA, Emerging...
