In this note we discuss the findings in Piskorski, Seru, and Vig (2010), as well as the authors' interpretation of their results. First, we find that small changes to the set of covariates used by PSV significantly reduce the magnitude of the differences in foreclosure rates between securitized...

In the aftermath of the global financial crisis, policymakers in the United States and elsewhere have adopted stress testing as a central tool for supervising large, complex, financial institutions and promoting financial stability. Although supervisory stress testing may confer substantial...

The authors exploit new data from the Panel Study of Income Dynamics (PSID) to provide a more systematic and detailed analysis of household-level employment, income, and expense shocks to mortgage default decisions than has been possible before. These new data provide very different answers...

This paper provides the first rigorous assessment of the homeownership experiences of subprime borrowers. We consider homeowners who used subprime mortgages to buy their homes, and estimate how often these borrowers end up in foreclosure. In order to evaluate these issues, we analyze...

This paper analyzes the effects of market structure on price dispersion in the airline industry, using panel data from 1993 through 2006. The results found in this paper contrast with those of Borenstein and Rose (1994), who found that price dispersion increases with competition. We find that...

We examine the effects of collateralized borrowing in a realistically parameterized life-cycle portfolio choice problem. We provide basic intuition in a two-period model and then solve a multi-period model computationally. Our analysis provides insights into life-cycle portfolio choice relevant...

The U.S. mortgage market links homeowners with savers all over the world. In this paper, we ask how much of the flow of money from savers to borrowers actually goes to the intermediaries that facilitate these transactions. Based on a new methodology and a new administrative dataset, we find that...

This paper reviews recent research on mortgage default, focusing on the relationship of this research to the recent foreclosure crisis. Research on defaults was advanced both theoretically and empirically by the time the crisis began, but economists have moved the frontier further by improving...

The reallocation of mortgage debt to low-income or marginally qualified borrowers plays a central role in many explanations of the early 2000s housing boom. We show that such a reallocation never occurred, as the distribution of mortgage debt with respect to income changed little even as the...

Shiller (2003) and others have argued for the creation of financial instruments that allow households to insure risks associated with their lifetime labor income. In this paper, we argue that while the purpose of such assets is to smooth consumption across states of nature, one must also...
