Risky Cash-Out Refis

Posted on by

Anil Kumar of the Dallas Fed has posted Do Restrictions on Home Equity Extraction Contribute to Lower Mortgage Defaults? Evidence from a Policy Discontinuity at the Texas’ Border to SSRN.  The abstract reads

Given that excessive borrowing helped precipitate the housing crisis, a key component of a policy agenda to prevent future meltdowns is effective regulation to curb unaffordable mortgage debt. Texas is the only US state that limits home equity borrowing to 80 percent of home value. Anecdotal reports have long suggested that home equity restrictions shielded Texas homeowners from the worst of the subprime mortgage crisis. But there is, as yet, no formal empirical investigation of these restrictions’ role in curbing mortgage default. This paper is the first to empirically estimate the impact of Texas home equity restrictions on mortgage default using individual and loan level data from three different sources. The paper exploits the policy discontinuity around Texas’ interstate borders induced by the home equity restrictions to identify the causal effect of home equity extraction on mortgage default in a border discontinuity design framework. The paper finds that limits on home equity borrowing in Texas lowered the likelihood of mortgage default by about 2 percentage points with a significantly larger impact on mortgage borrowers in the bottom quartile of the credit score distribution. Estimated default hazards for mortgages within 50 to 100 miles of the Texas’ border decline sharply as one crosses into Texas. Overall, the paper finds evidence that Texas’ home equity restrictions exert a robust negative impact on mortgage default.

This is a really important paper asking a really important question.  If its findings are confirmed, it brings us back to that age-old question of paternalism in consumer financial protection: should we limit a consumer’s choice if that choice is consistently shown to have harmful effects?  I am not sure where I come down in this particular case, but I wonder if some version of Quercia et al.‘s benefit ratio could help measure the costs and benefits of such a rule. The benefit ratio compares “the percent reduction in the number of defaults to the percent reduction in the number of borrowers who would have access to [a certain type of] mortgages.” (20) I am not sure whether access to cash out refi mortgages is of the same import as purchase mortgages or even plain old refis, but the concept of the benefit ratio might still make sense in this context.

The Unzoned City

Matt Festa has posted an interesting, short article, Land Use in the Unzoned City, to SSRN. He writes,

The popular conception that Houston is unzoned because it is some sort of ultra-Texan free-market landscape is not accurate. Houston’s land use is in fact highly regulated. While no Houston ordinance explicitly uses the “z-word,” and its rules for the most part don’t prescribe limitations on use, there are numerous land use regulations that, in any other city, would be part of the zoning code. Houston defines certain areas as “urban” versus “suburban,” with different regulations.There are laws prescribing minimum lot sizes, which in turn restrict density. There are setbacks from the street, buffer zones for development, and regulated street widths. There are other laws that affect land use, such as the new historical preservation ordinance, which allows citizens to petition the council for designation as a historic area, which comes with additional restrictions. These are all government measures that, in my opinion, operate as “de facto zoning”— they prescribe different land use rules based partly on geographic location. And even these rules pale in comparison to the extensive regime of private covenants and deed restrictions that govern a majority of the property in Houston. (17)

Festa explains that this lack of zoning may have some partial explanations that have to do with the culture of the city. But he finds a more compelling explanation in the ban on zoning contained in the Houston City Charter. This ban, which can only be overturned by referendum, has been challenged three times but zoning supporters have come up a bit short each time.

Festa is certainly correct that land use scholars (Edward Glaeser, for instance) use Houston as a foil to communities that heavily limit new construction with restrictive zoning provisions. So Festa’s thesis is an important one that I hope he develops in a longer article. Until we determine how much less restrictive Houston’s land use regime is than other American cities’ formal zoning ordinances, we can’t fully understand the interaction between restrictive land use policies and the housing crisis affecting cities across the country.
