Frannie v. Private-Label Smackdown

S&P posted a report, Historical Data Show That Agency Mortgage Loans Are Likely to Perform Significantly Better Than Comparable Non-Agency Loans. The overview notes,

  • We examined the default frequencies of both agency and non-­agency mortgage loans originated from 1999­-2008.
  • As expected, default rates for both agencies and non-­agencies were higher for crisis-­era vintages relative to pre­-crisis vintages.
  • The loan characteristics that were the most significant predictors of default were FICO scores, debt­-to­-income (DTI) ratios, and loan­-to­-value (LTV) ratios.
  • Agency loans performed substantially better than non­agency loans for all vintages examined. The default rate of agency loans was approximately 30%-­65% that for comparable non-­agency loans, whether analyzed via stratification or through a logistic regression framework. (1)

This is not so surprising, but it is interesting to see the relative performance of Frannie (Fannie & Freddie) and Private-Label loans quantified and it is worth thinking through the implications of this disparity.

S&P was able to do this analysis because Fannie and Freddie released their “loan-level, historical performance data” to the public in order to both increase transparency and to encourage private capital to return to the secondary mortgage market. (1) Given that the two companies have transferred significant credit risk to third parties in the last few years, this is a useful exercise for potential investors, regulators and policymakers.

It is unclear to me that this historical data gives us much insight into future performance of either Frannie or Private-Label securities because so much has changed since the 2000s. Dodd-Frank enacted the Qualified Mortgage, Ability-to-Repay and Qualified Mortgage regimes for the primary and secondary mortgage market and they have fundamentally changed the nature of Private-Label securities. And the fact that Fannie and Freddie are now in conservatorship has changed how they do business in very significant ways just as much. So, yes, old Frannie mortgages are likely to perform better, but what about new ones?

Inclusionary Housing and Equitable Communities

The Lincoln Institute of Land Policy has released a policy focus report, Inclusionary Housing: Creating and Maintaining Equitable Communities. The Executive Summary opens,

After decades of disinvestment, American cities are rebounding, but new development is often driving housing costs higher and displacing lower-income residents. For cities struggling to maintain economic integration, inclusionary housing is one of the most promising strategies available to ensure that the benefits of development are shared widely. More than 500 communities have developed inclusionary housing policies, which require developers of new market-rate real estate to provide affordable units as well. Economically diverse communities not only benefit low-income households; they enhance the lives of neighbors in market-rate housing as well. To realize the full benefit of this approach, however, policies must be designed with care. (3)

The report uses the term inclusionary zoning to refer to

a range of local policies that tap the economic gains from rising real estate values to create affordable housing—tying the creation of homes for low- or moderate-income households to the construction of market-rate residential or commercial development. In its simplest form, an inclusionary housing program might require developers to sell or rent 10 to 30 percent of new residential units to lower-income residents. Inclusionary housing policies are sometimes referred to as “inclusionary zoning” because this type of requirement might be implemented through an area’s zoning code; however, many programs impose similar requirements outside the zoning code. (7)

The report notes that

Policy makers are understandably concerned that affordable housing requirements will stand in the way of development. But a review of the literature on the economics of inclusionary housing suggests that well-designed programs can generate significant affordable housing resources without overburdening developers or landowners or negatively impacting the pace of development. (4)

The report is obviously addressing two of the most important issues facing us today — the housing affordability challenge that many households face as well as the increasing stratification of communities by income and wealth.

There is a lot of value in the survey of the academic literature on inclusionary housing policies that is provided by this report. At the same time, there is some fuzzy thinking in it too. For instance, the report states that, “As the basic notion of supply and demand suggests, the addition of new units in a given market will inevitably put some downward pressure on the cost of existing units. But the larger effect tends to be upward pressure on housing costs because new homes are primarily built for higher-income residents.” (12)

This analysis ignores the well-accepted concept of filtering in urban economics. Filtering describes the process by which occupants of housing units go from higher-income to lower-income as the unit ages, becomes outdated and is subject to wear and tear. If higher-income households move to the newest housing, then other another household, typically of lower-income, can move into the vacant unit. If the number of households remains constant, then housing prices should decrease as housing development increases.

Because the real world does not look like an economic model, many people think that new housing causes increased housing prices. But the cause of the increased housing prices is often the same thing that is causing new housing construction:  increased demand.

Take NYC for instance. In recent years, it issues permits for 10,000-20,000 or so new units of housing a year, but its population has grown by about 60,000 people a year. Combine this with the fact that new housing construction is both a sign and result of gentrification in a particular neighborhood, it is no wonder people think that housing construction pushes prices higher. While this is an understandable line of thought for the man or woman in the street, it is less so for the Lincoln Institute.

My bottom line: this is worth a read, but read with care.

 

Desvinculado y Desigual = Separate and Unequal

Justin Steil, Jorge De la Roca and Ingrid Gould Ellen, researchers affiliated to the NYU Furman Center, have published Desvinculado y Desigual [Separate and Unequal]: Is Segregation Harmful to Latinos? The authors find that their research on this topic “suggests that segregation may have as negative effects for Latinos as it does for African Americans and that persistent Latino-white segregation is of serious concern as the nation’s metropolitan areas continue to become more diverse.” (74)

More specifically, their research finds that

segregation continues to be associated with significant reductions in educational attainment and labor market success for African Americans, and that the associations between segregation and outcomes for Latinos are at least as large as those for African Americans. For native-born African American and Latino young adults between the ages of 20 and 30, increases in metropolitan-area segregation are associated with significant reductions in the likelihood of high school and college graduation, with lower earnings and employment rates, and with an increase in single motherhood.

These findings are somewhat unanticipated given the long history of intense black-white segregation and the systematic disinvestment in black neighborhoods through much of the last century, when compared to the historically more moderate levels of Latino-white segregation. These findings raise the question of which mechanisms may be at play to generate these differences.

One crucial mechanism seems to be the levels of neighborhood human capital to which whites, Latinos, and African Americans are exposed; they are consistent with the negative associations for both blacks and Latinos and with the differences in the magnitude of the association between them. The white-Latino gap in neighborhood exposure to human capital increases dramatically as levels of segregation increase.

The significance of neighborhood levels of human capital is consistent with existing research on the effects of segregation for African Americans and for immigrants. (73, citations omitted)

This is an understudied and important topic, so it is great that the authors have begun to explore it. They identify a number of research questions that others can take up. Let’s hope some do.
