The 30-year fixed-rate fully amortizing mortgage (or "traditional fixed-rate mortgage") was a substantial innovation when first developed during the Great Depression. However, it has three major flaws. First, because homeowner equity accumulates slowly during the first decade, homeowners are...

We document that banks reduce supply of jumbo mortgage loans when policy uncertainty increases as measured by the timing of US gubernatorial elections in banks' headquarter states. The reduction is larger for more uncertain elections. We utilize high-frequency, geographically granular loan data...

Past research argues that changes in adjustable-rate mortgage (ARM) payments may lead households to cut back on consumption or to default on their mortgages. In this paper, we argue that these outcomes are more likely if ARM borrowers are borrowing constrained, and find that ARM borrowers...

This paper uses a novel instrumental variables approach to quantify the effect that GSE purchase eligibility had on equilibrium mortgage loan terms in the period from 2003 to 2007. The technique is designed to eliminate sources of bias that may have affected previous studies. GSE eligibility...

We provide an empirical analysis of the effects of the Federal Reserve's asset holdings on MBS yields and mortgage rates. We argue that understanding the particulars of the U.S. mortgage markets, particularly the linkages between the secondary and primary mortgage markets, is important. We find...

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...

The U.S. mortgage crisis that began in 2007 generated questions about the role played by Fannie Mae and Freddie Mac, the Government-Sponsored Enterprises (GSEs), in its causes. Some have claimed that the Affordable Housing Goals (AHGs), introduced by Congress through the GSE Act of 1992, and the...

Using a property-level data set of houses in Los Angeles County, I estimate that 30% of the recent surge in mortgage defaults is attributable to early home-buyers who would not have defaulted had they not borrowed against the rising value of their homes during the boom. I develop and estimate a...
