We study a contracting model of leverage and balance sheet size for financial intermediaries that fund their activities through collateralized borrowing. Leverage and balance sheet size increase together when measured risks decrease. When the loss distribution is exponential, the behavior of...

In a 1999 paper, Freeman proposes a model in which discount window lending and open market operations have different outcomes—an important development because in most of the literature the results of these policy tools are indistinguishable. Freeman’s conclusion that the central bank should...

Banks face two different kinds of moral hazard problems: asset substitution by shareholders (e.g., making risky, negative net present value loans) and managerial rent seeking (e.g., investing in inefficient 'pet' projects and consuming perquisites that yield private benefits). The privately...

Foreign banks pulled signifi cant funding from their U.S. branches during the Great Recession. We estimate that the average-sized branch experienced a 12 percent net internal fund withdrawal, with the fund transfer disproportionately bigger for larger branches. This internal shock to the balance...

We describe and evaluate the measures taken by the U.S. government to rescue Fannie Mae and Freddie Mac in September 2008. We begin by outlining the business model of these two firms and their role in the U.S. housing finance system. Our focus then turns to the sources of financial distress that...

We build a general equilibrium model with financial frictions that impede the effectiveness of monetary policy in stimulating output. Agents with heterogeneous productivity can increase investment by levering up, but this increases interim liquidity risk. In equilibrium, the more productive...

I introduce the concept of hybrid intermediaries: financial conglomerates that control a multiplicity of entity types active in the "assembly line" process of modern financial intermediation, a system that has become known as shadow banking. The complex bank holding companies of today are the...
