This paper studies the optimal bankruptcy policy for repurchase agreements (repos) with respect to their exemption from the automatic stay of bankruptcy. The exemption from automatic stay has been one of the key contributors to the development of the repo market as a major source of funding for...

We study the effects of credit shocks in a model with heterogeneous entrepreneurs, financing constraints, and a realistic firm-size distribution. As entrepreneurial firms can grow only slowly and rely heavily on retained earnings to expand the size of their business, we show that, by reducing...

We explore the effects of financial shocks in heterogeneous agent economies with aggregate savings and with frictions in some consumption markets, where demand contributes to productivity. Households of various wealth and earnings levels search for goods at different intensities and pay...

This paper studies the relationship between the availability of unsecured credit to households and unemployment. We extend the Mortensen-Pissarides model to include a goods market with search and financial frictions. Households, who have limited commitment, face endogenous borrowing constraints...

Why are financial crises associated with a sustained rise in unemployment? We develop a tractable model with frictions in both credit and labor markets to study the aggregate andmicro-level implications of a credit crunch---i.e., a sudden tightening of collateral constraints. When we simulate a...

Using Bayesian methods, I estimate a DSGE model where a recession is initiated by losses suffered by banks and exacerbated by their inability to extend credit to the real sector. The event triggering the recession has the workings of a redistribution shock: a small sector of the economy --...

In 2005, reforms made formal personal bankruptcy much more costly. Shortly after, the US began to experience its most severe recession in seventy years, and while personal bankruptcy rates rose, they rose only modestly given the severity of the rise in unemployment. By contrast, informal default...

We analyze dynamic risk-sharing contracts between profit-maximizing insurers and risk-averse agents who face idiosyncratic income uncertainty and can self-insure through savings. We study Markov-perfect insurance contracts in which neither party can commit beyond the current period. We show that...

We develop a monetary model that is unique in its ability to deliver a negative correlation between aggregate consumption growth and short-term real interest rates consistent with U.S. data. The essential ingredient to this success is endogenous asset market segmentation permitting the extent of...
