I develop a macroeconomic model with a financial sector, in which banks can finance risky projects (loans) and can affect their quality by exerting a costly screening effort. Informational frictions regarding the observability of loan characteristics limit the amount of external funds that banks...

We investigate the cyclical properties of non-bank credit and its relevance for financial stability. We construct a measure of non-bank credit for a large sample of countries and find that its cyclical properties differ from those of bank credit. Non-bank credit cycles are highly correlated with...

I show that inter-firm lending plays an important role in business cycle fluctuations. I first build a tractable network model of the economy in which trade in intermediate goods is financed by supplier credit. In the model, a financial shock to one firm affects its ability to make payments to...

One of the major reasons hypothesized for the tepid economic recovery thus far is the ongoing "deleveraging" process. From 2009:Q3 to 2011:Q3, aggregate household debt declined by about $1.5 trillion in real terms, with mortgage debt falling by about $1 trillion. Other than defaults, the factors...

I use micro data to quantify key features of U.S. firm financing. In particular, I establish that a substantial 35% of firms' investment is funded using financial markets. I then construct a dynamic equilibrium model that matches these features and fit the model to business cycle data using...

The recent Global Games literature makes important predictions on how financial crises unfold. We test the empirical relevance of these theories by analyzing how dispersed information affects banks' default risk. We find evidence that precise information acts as a coordination device which...

From 1999 to 2013, U.S. mortgage debt doubled and then contracted sharply. Our understanding of the factors driving this volatility in the stock of debt is hampered by a lack of data on mortgage flows. Using comprehensive, individual-level panel data on consumer liabilities, I estimate detailed...

Modern central bankers confront a challenge of providing economic stimulus even when the policy rate is constrained by a lower bound. This challenge has led to substantial innovation by policymakers and a proliferation of new policy tools. In this paper, I offer evidence on the efficacy of a new...

I pool data from all large multimarket lenders in the U.S. to estimate how many of the over seven million jobs lost in the Great Recession can be explained by reductions in the supply of mortgage credit. I construct a mortgage credit supply instrument at the county level, the weighted average...

We explore the structural drivers of bank and nonbank credit cycles using an estimated medium-scale macro model that allows for bank and nonbank financial intermediation. We posit economy-wide aggregate and sectoral disturbances to potentially drive bank and nonbank credit growth. We find that...
