This paper explores the role of bank balance sheets, sovereign default risk, and capital adequacy requirements in amplifying aggregate fluctuations. The paper, first, proposes a unified model of defaultable sovereign debt and bank balance sheets to capture regularities on bank credit to firms,...

Emerging economies are characterized by higher variability of consumption and real wages relative to output and a strongly countercyclical current account. A small open economy model with search‐matching frictions and countercyclical interest rate shocks can account for these regularities....

This paper explores how banks' balance sheets and sovereign risk affect macroeconomic fluctuations jointly. The heightened sovereign risk and a potential default constrain the banks' ability to extend credit to firms. This happens through the capital requirement that limits the size of the bank...

Emerging economies are characterized by higher consumption and real wage variability relative to output and a strongly countercyclical current account. A real business cycle model of a small open economy that embeds a Mortensen-Pissarides type of search-matching frictions and countercyclical...

The interaction between credit frictions, financial innovation, and a switch from optimistic to pessimistic beliefs played a central role in the 2008 financial crisis. This paper develops a quantitative general equilibrium framework in which this interaction drives the financial amplification...

Financial innovation and overconfidence about the risk of new financial products were key factors behind the 2008 U.S. credit crisis. We show that a model with a collateral constraint in which learning about the risk of a new financial environment interacts with Fisherian amplification produces...
