The current financial crisis has made it abundantly clear that business cycle modeling can no longer abstract from financial factors. It is also clear that the current standard approach of modeling labor markets without explicit unemployment has its limitations. We extend what is becoming the...

Which are the main frictions and driving forces of business cycle dynamics in a small open economy? To answer this question we extend what is becoming the standard new Keynesian model in three dimensions. First, we incorporate frictions in the financing of the capital stock. Second, we model...

We explore the implications of shocks to expected future productivity in a setting with limited enforcement of financial contracts. As in Lorenzoni andWalentin (2007) optimal financial contracts under limited enforcement imply that to obtain external finance firms have to post collateral in...

Research on disaggregate price indices has found that sectoral shocks generate the bulk of sectoral inflation variance, but no persistence. Aggregate shocks, by contrast, are the root of sectoral inflation persistence, but have negligible relative variance. We argue that these findings are...

Recent work has shown that microeconomic shocks at the firm and sector level account for a substantial share of output volatility. We examine whether this relationship holds for house price growth volatility, which also declined during the Great Moderation and increased after 2001. Using a novel...
