I propose and estimate a dynamic model of financial intermediation to study the different roles of the condition of banks' and firms' balance sheets in real activity. The net worth of firms determines their borrowing capacity both from households and banks. Banks provide risky loans to multiple...

How does uncertainty affect the costs of raising finance in the bond market and via bank loans? Empirically, this paper finds that heightened uncertainty is accompanied by an increase in corporate bond yields and a decrease in bank lending rates. This finding can be explained with a model that...

We introduce financial frictions in the spirit of Bernanke, Gertler, and Gilchrist (1999) into a standard RBC model and use the heterogeneous-prior framework of Angeletos, Collard, and Dellas (2018) to accommodate confidence-driven business cycle fluctuations. We show that financial frictions...

The recent sovereign debt crisis in the Eurozone was characterized by a monetary policy, which has been constrained by the zero lower bound (ZLB) on nominal interest rates, and several countries, which faced high risk spreads on their sovereign bonds. How is the government spending multiplier...

This paper investigates the macroeconomic effects of uncertainty originating in the financial sector. My contribution is twofold. First, I document empirical relevenace of financial uncertainty using SVAR methods. Then, I employ the DSGE framework developed by Gertler and Karadi (2011) to...

The recent sovereign debt crisis in the Eurozone was characterized by a monetary policy, which has been constrained by the zero lower bound (ZLB) on nominal interest rates, and several countries, which faced high risk spreads on their sovereign bonds. How is the government spending multiplier...

At the forefront of macroeconomic research on the causes of the Great Financial Crisis (GFC) was and still is the usage of dynamic stochastic general equilibrium (DSGE) models. To capture the nonlinearities of the GFC, these models were enriched with a variety of fiÂ…nancial frictions. This...

Long-term debt contracts transfer aggregate risk from borrowing firms to lending banks. When aggregate shocks increase the future default probability of firms, banks are not compensated for the default risk of existing contracts. If banks are highly leveraged, this can lead to financial...

In the presence of financial frictions, banks' capital position may constrain their ability to provide loans. The banking sector may thus have important feedback effects on the macroeconomy. To shed new light on this issue, we combine two approaches. First, we use microeconomic balance sheet...
