The Economics of Housing Supply


chart by Smallman12q

Housing economists Edward L. Glaeser and Joseph Gyourko have posted The Economic Implications of Housing Supply to SSRN (behind a paywall but you can find a slightly older version of the paper here). The abstract reads,

In this essay, we review the basic economics of housing supply and the functioning of US housing markets to better understand the distribution of home prices, household wealth and the spatial distribution of people across markets. We employ a cost-based approach to gauge whether a housing market is delivering appropriately priced units. Specifically, we investigate whether market prices (roughly) equal the costs of producing the housing unit. If so, the market is well-functioning in the sense that it efficiently delivers housing units at their production cost. Of course, poorer households still may have very high housing cost burdens that society may wish to address via transfers. But if housing prices are above this cost in a given area, then the housing market is not functioning well – and housing is too expensive for all households in the market, not just for poorer ones. The gap between price and production cost can be understood as a regulatory tax, which might be efficiently incorporating the negative externalities of new production, but typical estimates find that the implicit tax is far higher than most reasonable estimates of those externalities.

The paper’s conclusions, while a bit technical for a lay audience, are worth highlighting:

When housing supply is highly regulated in a certain area, housing prices are higher and population growth is smaller relative to the level of demand. While most of America has experienced little growth in housing wealth over the past 30 years, the older, richer buyers in America’s most regulated areas have experienced significant increases in housing equity. The regulation of America’s most productive places seems to have led labor to locate in places where wages and prices are lower, reducing America’s overall economic output in the process.

Advocates of land use restrictions emphasize the negative externalities of building. Certainly, new construction can lead to more crowded schools and roads, and it is costly to create new infrastructure to lower congestion. Hence, the optimal tax on new building is positive, not zero. However, there is as yet no consensus about the overall welfare implications of heightened land use controls. Any model-based assessment inevitably relies on various assumptions about the different aspects of regulation and how they are valued in agents’ utility functions.

Empirical investigations of the local costs and benefits of restricting building generally conclude that the negative externalities are not nearly large enough to justify the costs of regulation. Adding the costs from substitute building in other markets generally strengthens this conclusion, as Glaeser and Kahn (2010) show that America restricts building more in places that have lower carbon emissions per household. If California’s restrictions induce more building in Texas and Arizona, then their net environmental could be negative in aggregate. If restrictions on building limit an efficient geographical reallocation of labor, then estimates based on local externalities would miss this effect, too.

If the welfare and output gains from reducing regulation of housing construction are large, then why don’t we see more policy interventions to permit more building in markets such as San Francisco? The great challenge facing attempts to loosen local housing restrictions is that existing homeowners do not want more affordable homes: they want the value of their asset to cost more, not less. They also may not like the idea that new housing will bring in more people, including those from different socio-economic groups.

There have been some attempts at the state level to soften severe local land use restrictions, but they have not been successful. Massachusetts is particularly instructive because it has used both top-down regulatory reform and incentives to encourage local building. Massachusetts Chapter 40B provides builders with a tool to bypass local rules. If developers are building enough formally-defined affordable units in unaffordable areas, they can bypass local zoning rules. Yet localities still are able to find tools to limit local construction, and the cost of providing price-controlled affordable units lowers the incentive for developers to build. It is difficult to assess the overall impact of 40B, especially since both builder and community often face incentives to avoid building “affordable” units. Standard game theoretic arguments suggest that 40B should never itself be used, but rather work primarily by changing the fallback option of the developer. Massachusetts has also tried to create stronger incentives for local building with Chapters 40R and 40S. These parts of their law allow for transfers to the localities themselves, so builders are not capturing all the benefits. Even so, the Boston market and other high cost areas in the state have not seen meaningful surges in new housing development.

This suggests that more fiscal resources will be needed to convince local residents to bear the costs arising from new development. On purely efficiency grounds, one could argue that the federal government provide sufficient resources, but the political economy of the median taxpayer in the nation effectively transferring resources to much wealthier residents of metropolitan areas like San Francisco seems challenging to say the least. However daunting the task, the potential benefits look to be large enough that economists and policymakers should keep trying to devise a workable policy intervention. (19-20)

Hope for the Securitization Market

The Structured Finance Industry Group has issued a white paper, Regulatory Reform: Securitization Industry Proposals to Support Growth in the Real Economy. While the paper is a useful summary of the industry’s needs, it would benefit from looking at the issue more broadly. The paper states that

One of the core policy responses to the financial crisis was the adoption of a wide variety of new regulations applicable to the securitization industry, largely in the form of the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank”). While many post-crisis analysts believe that the crisis laid bare the need for meaningful regulatory reform, SFIG members believe that any such regulation must: ƒ

  • Reduce risk in a manner such that benefits outweigh costs, including operational costs and inefficiencies; ƒ
  • Be coherent and consistent across the various sectors and across similar risk profiles; ƒ
  • Be operationally feasible from both a transactional and a loan origination basis so as not to compromise provision of credit to the real economy; ƒ
  • Be valued by key market participants; and ƒ
  • Be implemented in a targeted way (i.e. without unintended consequences).

In this paper, we will distinguish between the types of regulation we believe to be necessary and productive versus those that are, at the very least, not helpful and, in some cases, harmful. To support this approach, we believe it is helpful to evaluate financial market regulations, specifically those related to securitization, under three distinct categories, those that are:

1. Transactional in nature; i.e., directly impact the securitization market via a focus on underlying deal structures;

2. Banking rules that include securitization reform within their mandate; and

3. Banking rules that simply do not contemplate securitization and, therefore, may result in unintended consequences. (3)

The paper concludes,

The securitization industry serves as a mechanism for allowing institutional investors to deliver funding to the real economy, both to individual consumers of credit and to businesses of all sizes. This segment of credit reduces the real economy’s reliance on the banking system to deliver such funding, thereby reducing systemic risk.

It is important that both issuers of securitization bonds and investors in those bonds align at an appropriate balance in their goals to allow those issuers to maintain a business model that is not unduly penalized for using securitization as a funding tool, while at the same time, ensuring investors have confidence in the market via “skin in the game” and sufficiency of disclosure. (19)

I think the paper is totally right that we should design a regulatory environment that allows for responsible securitization. The paper is, however, silent on the interest of consumers, whose loans make up the collateral of many of the mortgage-backed and asset-backed securities that are at issue in the bond market. The system can’t be designed just to work for issuers and investors, consumers must have a voice too.

GSE Conservatorship History Lesson

Mark Calabria, the Director of Financial Regulation Studies at the Cato Institute, has posted a very interesting paper, The Resolution of Systemically Important Financial Institutions: Lessons from Fannie and Freddie. This is a more formal version of what he presented at the AALS meeting early this month. I do not agree with all of Mark’s analysis, but this paper certainly opened my eyes about what can happen in committee when important statutes are being drafted. It opens,

There was perhaps no issue of greater importance to the financial regulatory reforms of 2010 than the resolution, without taxpayer assistance, of large financial institutions. The rescue of firms such as AIG shocked the public conscience and provided the political force behind the passage of the Dodd-Frank Act. Such is reflected in the fact that Titles I and II of Dodd-Frank relate to the identification and resolution of large financial entities. How the tools established in Titles I and II are implemented are paramount to the success of Dodd-Frank. This paper attempts to gauge the likely success of these tools via the lens of similar tools created for the resolution of the housing government sponsored enterprises (GSEs), Fannie Mae and Freddie Mac.
An additional purpose of this paper is to provide some additional “legislative history” to the resolution mechanisms contained in the Housing and Economic Recovery Act of 2008 (HERA), which established a resolution framework for the GSEs similar to that ultimately created in Title II of Dodd-Frank. The intent is to inform current debates over the resolution of systemically important financial institutions by revisiting how such issues were debated and agreed upon in HERA. (1-2)
As an outside-the-Beltway type, I found the “legislative history” very interesting, even if it wouldn’t qualify as any type of legislative history that a judge would consider in interpreting a statute. It does, however, offer policy wonks, bureaucrats and politicians an inside view of how a Congressional staffer helps to make the sausage that is legislation. It also shows that in the realm of legislation, as in the realm of fiction, author’s intent can play out in tricky ways.

Calabria concludes,

The neglect of HERA’s tools and the likely similar neglect of Dodd-Frank’s suggest a much deeper reform of our financial regulatory system is in order. The regulatory culture of “whatever it takes” must be abandoned. A respect for the rule of law and obedience to the letter of the law must be instilled in our regulatory culture. More important, the incentives facing regulators must be dramatically changed. If we hope to end “too-big-to-fail” and to curtail moral hazard more generally, significant penalties must be created for rescues as well as deviations from statute. A very difficult question is that lack of standing for any party to litigate to enforce statutory prohibitions against rescues. (19)

I take a couple of lessons from this paper. First, tight drafting of legislation that is supposed to kick in during a crisis is key. If a statute has wiggle room, decision makers are going to stretch it out as they see fit. And second, I agree with Mark that even tight drafting won’t necessarily keep government actors from acting as they see fit in a crisis.

If Congress really want to constrain the choices of future decision makers, it will need to grant a third party standing to enforce that decision as it is unlikely that crisis managers will have the self-restraint to forgo options that they would otherwise prefer. Congress should be very careful about constraining the choices of these future decision makers. But if it chooses to do so, that would be the way to go.

 

Promoting Affordable Housing, and the Winner Is . . .

I had blogged about a competition to generate ideas to lower the cost of affordable housing, the Minnesota Challenge to Lower the Cost of Affordable Housing.  I was pretty excited about this challenge and was happy to see that a winner has been chosen:  the University of Minnesota’s Center for Urban and Regional Affairs (CURA).

CURA’s winning proposal is here.  Basically, they

propose a three-stage program for addressing the state and local regulatory cost driver. First, we will identify and summarize best practices at the state and local levels for reducing regulatory and permitting barriers to affordable housing. There is a significant national database of initiatives that can provide examples for possible implementation here, as well as the Affordable Housing Toolkit established by ULI Minnesota. Second, we will conduct an analysis of where a more complete adoption of best practices is likely to have the largest effect on the production of affordable housing, particularly those suburban cities with the largest future affordable housing goals. Finally, we will take advantage of the fact that the Metropolitan Council of the Twin Cities is currently drafting a Regional Housing Policy plan, which is a vehicle that could implement regulatory reforms and create incentives for local governments to adopt practices and policies to reduce development costs. (1)
These are all valuable things to do, but I have to say that I am disappointed that this is as good as it gets when it comes to innovation regarding reducing the cost of affordable housing construction. Perhaps the takeaway lesson is that building affordable housing is expensive and that we can only cut costs a bit at the margins. I am hoping, however, that I am wrong about that and that some innovative ideas are still out there. Are there big ideas about inclusionary zoning?  About modular construction? About public/private partnerships? We’ll have to wait and see.
