This paper assesses the relative importance of two key drivers of mortgage default: negative equity and illiquidity. To do so, the authors combine loan-level mortgage data with detailed credit bureau information about the borrower's broader balance sheet. This gives them a direct way to measure...

In many countries, lenders are restricted in their access to information about borrowers' past defaults. The authors study this provision in a model of repeated borrowing and lending with moral hazard and adverse selection. They analyze its effects on borrowers' incentives and access to credit,...

The dramatic increase in U.S. personal bankruptcy filings of the last fifteen years has focused attention on the wide disparities between different states' personal bankruptcy exemptions. These differences have been criticized both on the grounds of equity and also because they provide an...

We show that at any equilibrium of almost every single-good incomplete markets economy, it is possible to find an asset which when introduced makes every agent better-off. Diamond (1967) has shown, however, that such economies are constrained suboptimal, so it is of course impossible to find a...

We use a matched credit bureau and mortgage data set to identify occupancy fraud in residential mortgage originations, that is, borrowers who misrepresented their occupancy status as owner occupants rather than residential real estate investors. In contrast to previous studies, our data set...

Refinancing a first mortgage puts legal principles in conflict when other, junior, liens also exist. On one hand, the principle that seniority follows time priority leaves the new refinancing mortgage junior to mortgages that were junior to the original, refinanced first mortgage. On the other...

We find that private-securitized loans perform worse than observably similar, nonsecuritized loans, which provides evidence for adverse selection. The effect of securitization is strongest for prime mortgages, which have not been studied widely in the previous literature and particular prime...

Residential house price indexes (HPI) are used for a large variety of macroeconomic and microeconomic research and policy purposes, as well as for automated valuation models. As is well known, these indexes are subject to substantial revisions in the months following the initial release, both...

In many countries, lenders are not permitted to use information about past defaults after a specified period of time has elapsed. We model this provision and determine conditions under which it is optimal. We develop a model in which entrepreneurs must repeatedly seek external funds to finance a...

We develop a simple model in which financial imperfections can serve to stabilize aggregate fluctuations and not merely aggravate them as in much of the previous literature; we term this a financial decelerator.In our model agents borrow to purchase housing and secure their loans with this...
