This paper studies the extent to which alternative loan loss provisioning regimes affect the procyclicality of the financial system and financial stability. It uses a DSGE model with financial frictions (namely, balance sheet and collateral effects, as well as economies of scope in banking) and...

This paper investigates the effect of cyclical macroeconomic policy and financial sector characteristics on growth. Using cross-country, cross-industry OECD data, it yields two main findings. First, countercyclical fiscal and monetary policies foster growth disproportionately in more...

We develop a quantitative business cycle model with search complementarities in the inter-firm matching process that entails a multiplicity of equilibria. An active equilibrium with strong joint venture formation, large output, and low unemployment coexists with a passive equilibrium with low...

We document five novel facts about the role of search effort in forming trading relationships among firms by combining a variety of micro and macro datasets. These facts strongly suggest the presence of search complementarities. To study the implications of these facts for aggregate...
