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)

High Rents and Land Use Regulation

The Federal Reserve’s Devin Bunten has posted Is the Rent Too High? Aggregate Implications of Local Land-Use Regulation. It is a technical paper about an important subject. It has implications for those who are concerned about the lack of affordable housing in high-growth areas. The abstract reads,

Highly productive U.S. cities are characterized by high housing prices, low housing stock growth, and restrictive land-use regulations (e.g., San Francisco). While new residents would benefit from housing stock growth in cities with highly productive firms, existing residents justify strict local land-use regulations on the grounds of congestion and other costs of further development. This paper assesses the welfare implications of these local regulations for income, congestion, and urban sprawl within a general-equilibrium model with endogenous regulation. In the model, households choose from locations that vary exogenously by productivity and endogenously according to local externalities of congestion and sharing. Existing residents address these externalities by voting for regulations that limit local housing density. In equilibrium, these regulations bind and house prices compensate for differences across locations. Relative to the planner’s optimum, the decentralized model generates spatial misallocation whereby high-productivity locations are settled at too-low densities. The model admits a straightforward calibration based on observed population density, expenditure shares on consumption and local services, and local incomes. Welfare and output would be 1.4% and 2.1% higher, respectively, under the planner’s allocation. Abolishing zoning regulations entirely would increase GDP by 6%, but lower welfare by 5.9% because of greater congestion.

The important sentence from the abstract is that “Welfare and output would be 1.4% and 2.1% higher, respectively, under the planner’s allocation.” Those are significant effects when we are talking about  real people and real places. The introduction provides a bit more context for the study:

Neighborhoods in productive, high-rent regions have very strict controls on housing development and very limited new housing construction. Home to Silicon Valley, the San Francisco Bay Area is the most productive and most expensive metropolitan region in the country, and yet new housing construction has been very slow, especially in contrast to less-productive large cities like Houston, Texas. The evidence suggests that this slow-growth environment results from locally determined regulatory constraints. Existing residents justify these constraints by appealing to the costs of new development, including increased vehicle traffic and other types of congestion, and claim that they see few, if any, of the benefits from new development. However, the effects of local regulation extend beyond the local regulating authorities: regions with highly regulated municipalities experience less-elastic housing supply. (2, footnotes omitted)

The bottom line, as far as I am concerned, is that localities that are attempting to deal with their affordable housing problems have to directly address how they go about their zoning. If the zoning does not support housing construction, then no amount of affordable housing incentives will address the demand for housing in high growth places like NYC and San Francisco.

Dodd-Frank Repeal Unappealing for Homeowners

Congressman Jeb Hensarling

The Hill published my latest column, Why Repealing Dodd-Frank Is Unappealing if You Own a Home. It opens, 

President Trump has made it clear that he wished to dismantle the Dodd-Frank Wall Street Reform and Consumer Protection Act. Just two weeks after his inauguration, he issued an executive order to get the ball rolling by means of agency action, an effort that will be led by the Department of the Treasury. Trump will have lots of allies in Congress as he pursues this agenda. A recent memo by House Financial Services Chairman Jeb Hensarling (R-Texas) to his committee’s leadership team outlines a legislative path that leads to much the same goal.

One of the key components of the Dodd-Frank regulatory regime was the newly-created Consumer Financial Protection Bureau (CFPB). The bureau is responsible for administering a range of consumer protection regulations, some of which predate Dodd-Frank and some of which were mandated by it. Homeowners should sit up and take notice because a lot of protections they can now take for granted will be stripped away if this push is successful.

Many of these regulations protect homeowners as they obtain mortgages for their homes. Others protect homeowners over the life of the mortgages, particularly when they are having trouble keeping up with their mortgage payments because of those common life events that still knock us for a loop when they happen to us: job loss, divorce, medical bills, a death in the family.

Hensarling’s memo makes clear the extent to which he wants to weaken the CFPB. Among many other things, he wants to eliminate the bureau’s consumer education functions, bar it from commencing actions involving unfair, deceptive or abusive acts and practices, end its practice of tracking consumer complaints, and stop if from monitoring and conducting research on the consumer credit market.

Before the financial crisis, homeowners suffered from a range of abusive and predatory behaviors that were prevalent in the mortgage industry for years and years. Lenders would lend without regard to a borrower’s ability to repay a loan, so long as there was sufficient equity in the home to make the lender whole after a foreclosure. Dodd-Frank’s ability-to-repay rule keeps lenders from doing that now. Lenders would make loans that had large balloon payments at the end of the term, forcing unsophisticated borrowers to refinance with all of the fees and costs that that entails. The lenders would look at those refinancing costs as another profit center. Dodd-Frank’s qualified mortgage rule banned those abusive balloon payments for the most part.

While Hensarling claims that Dodd-Frank “clogs the arteries of capitalism,” he seems to forget that unfettered capitalism nearly gave us a fatal heart attack just 10 years ago, when the subprime mortgage crisis led us to the brink of a second Great Depression. He seems to forget that predatory mortgage lending is not only bad for the individuals affected by it, but also for the housing market and economy in general. Housing prices did not just fall for those with unsustainable mortgages—they fell for all of us.

The push to get rid of the CFPB is not being driven by the consumer finance industry. The industry has learned to live with the bureau. It has come to see that there are some benefits that accrue from primarily dealing with one regulator, in place of the patchwork of regulators that was the norm before Dodd-Frank. Rather, the push is being driven by an unfettered free market ideology that is out of step with the workings of the modern economy.

Getting rid of the CFPB will be bad for homeowners. They will no longer be able to assume that a mortgage they receive is one that has payments they can make month-in and month-out. They will need to treat lenders as predators because predatory lending will certainly return to the mortgage market. Caveat emptor.

Trump and The Housing Market

President-Elect Trump

TheStreet.com quoted me in 5 Ways the Trump Administration Could Impact the 2017 U.S. Housing Market. It opens,

Yes, President-elect Donald Trump may have chosen Ben Carson to lead the Department of Housing and Urban Development, but as the U.S. housing market revs its engines as 2016 draws to a close, an army of homeowners, real estate professionals and economists are focused on cheering on a potentially rosy market in 2017.

And with good reason.

According to the S&P CoreLogic Case-Shiller Indices released on November 29, U.S. housing prices rose, on average, by 5.5% from September, 2015 to September, 2016. Some U.S. regions showed double-digit growth for the time period – Seattle, saw an 11.0% year-over-year price increase, followed by Portland, Ore. with 10.9% and Denver with an 8.7% increase, according to the index.

The data point to further growth next year, experts say.

“The new peak set by the S&P Case-Shiller CoreLogic National Index will be seen as marking a shift from the housing recovery to the hoped-for start of a new advance,” notes David M. Blitzer, chairman of the index committee at S&P Dow Jones Indices. “While seven of the 20 cities previously reached new post-recession peaks, those that experienced the biggest booms — Miami, Tampa, Phoenix and Las Vegas — remain well below their all-time highs. Other housing indicators are also giving positive signals: sales of existing and new homes are rising and housing starts at an annual rate of 1.3 million units are at a post-recession peak.”

But there are question marks heading into the new year for the housing market. The surprise election of Donald Trump as president has industry professionals openly wondering how a new Washington regime will impact the real estate sector, one way or another.

For instance, Dave Norris, chief revenue officer of loanDepot, a retail mortgage lender located in Orange County, Calif., says dismantling the Consumer Financial Protection Bureau, encouraging higher interest rates, and broadening consumer credit are potential scenario shifters for the housing market in the early stages of a Trump presidency.

Other experts contacted by TheStreet agree with Norris and say change is coming to the housing market, and it may be more radical than expected. To illustrate that point, here are five key takeaways from market experts on how a Trump presidency will shape the 2017 U.S. real estate sector.

Expect higher interest rates – The new administration will likely lead to higher interest rates, which will compress home and investment property values, says Allen Shayanfekr, chief executive officer of Sharestates, an online crowd-funding platform for real estate financing. “Specifically, loans are calculated through debt service coverage ratios and a borrower’s ability to make their payments,” Shayanfekr says. “Higher interest rates mean larger monthly payments and in turn, lower loan amount qualifications. If lenders tighten up, it will restrict the buyer market, causing either a plateau in market values or possibility a decrease depending on the margin of increased rates.”

Housing reform will also impact home purchase costs – Trump’s effect on interest rates will likely depress housing prices in some ways, says David Reiss, professor of law at Brooklyn Law School. “That’s because the higher the monthly cost of a mortgage, the lower the price that the seller can get,” he notes. Reiss cites housing reform as a good example. “Housing finance reform will increase interest rates,” he says. “Republicans have made it very clear that they want to reduce the role of the federal government in the housing market in order to reduce the likelihood that taxpayers will be on the hook for another bailout. If they succeed, this will likely raise interest rates because the federal government’s involvement in the mortgage market tends to push interest rates down.”

Another Housing Bubble?

bubble-500130_1280

Trulia quoted me in Warning Signs: Another Housing Bubble Is Coming. It opens,

Signs show another bubble coming. Some experts have a different opinion.

When the housing market crashed in 2008, it caused what came to be known as ”The Great Recession.” When the bubble burst, it ”sent a shock through the entire financial system, increasing the perceived credit risk throughout the economy,” according to a report published in The Journal of Business Inquiry.

The crash caused homes to lose up to half their value. People became underwater, owing more than their home was worth. And who wants to pay on a mortgage that’s larger than what the home could sell for? Although some people did just that, many more opted to short sell their homes or to simply walk away and have the bank foreclose.

Present Day

Fast-forward to 2016, and we are seeing hot, even ” overheated,” housing markets; bidding wars; rising home prices; and house flippers – all the signs of a housing bubble that’s about to burst. Are we repeating the mistakes we made before? Yes and no. Let’s explore four reasons the housing bubble burst and whether we’re experiencing the same conditions today.

1. Easy Credit

Before the 2008 crash, credit was easy to get. Pretty much, if you were breathing, you could get a mortgage loan. This led to people getting mortgages who ultimately couldn’t afford to pay them back. They lost their homes, and this contributed in large part to the housing crisis. Today the situation is different. ”Credit is still much tighter than it was before the financial crisis,” says David Reiss, professor of law at Brooklyn Law School. ”This is particularly true for those with less-than-perfect credit scores.” He explains: ”There are almost no no-down-payment loans as there were in the early 2000s. Those defaulted at incredibly high rates.”

But what about Federal Housing Administration (FHA) loans? They feature ”low down payments, low closing costs, and easy credit qualifying.” Those are the very features that should sound some warning bells. But before you get too alarmed, keep in mind that the FHA has been making loans to people who do not qualify for a conventional mortgage since 1934. ”While there are low-down-payment loans available from Fannie, Freddie, and the FHA, their underwriting standards appear to be higher than those for low-down-payment products from the early 2000s,” says Reiss.

2. Low Interest Rates

Mortgage rates have been low for so long that you might not realize that was not always the case. In 1982, for example, mortgage rates were 18 percent. From 2002 to 2005, the rates stayed at about 6 percent, which enticed people to take out mortgage loans. And in 2016, we’re seeing historic lows of under 3.5 percent. If rates go up, we might see housing demand and housing prices fall.

3. ARMS

Before the housing crash when home prices were rising fast, many people were priced out of the market with a fixed-rate mortgage because they couldn’t afford the monthly mortgage payments. But they could afford lower payments that were possible with an adjustable-rate mortgage – until that rate adjusted up. In 2005, 38.5 percent of the mortgage market was ARMs. But in 2015, that amount has dropped considerably to 5.3 percent.

4. A Buying Frenzy

There’s an old story that before the stock market crash of 1929, Joseph Kennedy, Sr., sold his shares. Why? Because he received a stock tip from a shoeshine boy. Kennedy figured, the story goes, that if the stock market was popular enough for a shoeshine boy to be interested, the speculative bubble had become too big.

Before the housing crash, this country saw a home buying frenzy similar to what happened before the stock market crash. Everyone from lenders to rating agencies to investors (foreign and American) to investment bankers to home buyers was eager to get into the mortgage game because house values kept rising. Today, we are seeing a similar buying frenzy in some markets, such as San Francisco, New York, and Miami . Some experts think that the price increases of homes in those areas are not sustainable. They say that because heavy foreign investment in those areas is part of what’s driving up prices, if those investments slow or stop, we could see a bubble burst.

So what do some experts think?

David Ranish, owner/broker for The Coastline Real Estate Group in Laguna Beach, CA, says: ”There are concerns about another housing bubble, but I do not see it. The market could stabilize, but a complete collapse is highly unlikely.”

Bruce Ailion, an Atlanta, GA, real estate expert, says,” ”Five to six years ago, I was a buyer of homes. Today I am a seller.”

David Reiss says, ”It is probably a fool’s game to predict the future of the housing market or whether we are in a bubble that is soon to burst.”

Investing in Mortgage-Backed Securities

photo by https://401kcalculator.org

US News & World Report quoted me in Why Investors Own Private Mortgage-Backed Securities. It opens,

Private-label, or non-agency backed mortgage securities, got a black eye a few years ago when they were blamed for bringing on the financial crisis. But they still exist and can be found in many fixed-income mutual funds and real estate investment trusts.

So who should own them – and who should stay away?

Many experts say they’re safer now and are worthy of a small part of the ordinary investor’s portfolio. Some funds holding non-agency securities yield upward of 10 percent.

“The current landscape is favorable for non-agency securities,” says Jason Callan, head of structured products at Columbia Threadneedle Investments in Minneapolis, pointing to factors that have reduced risks.

“The amount of delinquent borrowers is now at a post-crisis low, U.S. consumers continue to perform quite well from a credit perspective, and risk premiums are very attractive relative to the fundamental outlook for housing and the economy,” he says. “Home prices have appreciated nationwide by 5 to 6 percent over the last three years.”

Mortgage-backed securities are like bonds that give their owners rights to share in interest and principal received from homeowners’ mortgage payments.

The most common are agency-backed securities like Ginnie Maes guaranteed by the Federal Housing Administration, or securities from government-authorized companies like Fannie Mae and Freddie Mac.

The agency securities carry an implicit or explicit guarantee that the promised principal and interest income will be paid even if homeowners default on their loans. Ginnie Mae obligations, for instance, can be made up with federal tax revenues if necessary. Agency securities are considered safe holdings with better yields than alternatives like U.S. Treasurys.

The non-agency securities are issued by financial firms and carry no such guarantee. Trillions of dollars worth were issued in the build up to the financial crisis. Many contained mortgages granted to high-risk homeowners who had no income, poor credit or no home equity. Because risky borrowers are charged higher mortgage rates, private-label mortgage securities appealed to investors seeking higher yields than they could get from other holdings. When housing prices collapsed, a tidal wave of borrower defaults torpedoed the private-label securities, triggering the financial crisis.

Not many private-label securities have been issued in the years since, and they accounted for just 4 percent of mortgage securities issued in 2015, according to Freddie Mac. But those that are created are considered safer than the old ones because today’s borrowers must meet stiffer standards. Also, many of the non-agency securities created a decade or more ago continue to be traded and are viewed as safer because market conditions like home prices have improved.

Investors can buy these securities through bond brokers, but the most common way to participate in this market is with mutual funds or with REITs that own mortgages rather than actual real estate.

Though safer than before, non-agency securities are still risky because, unlike agency-backed securities, they can incur losses if homeowners stop making their payments. This credit risk comes atop the “prepayment” and “interest rate” risks found in agency-backed mortgage securities. Prepayment risk is when interest earnings stop because homeowners have refinanced. Interest rate risk means a security loses value because newer ones offer higher yields, making the older, stingier ones less attractive to investors.

“With non-agencies, you own the credit risk of the underlying mortgages,” Callan says, “whereas with agencies the (payments) are government guaranteed.”

Another risk of non-agency securities: different ones created from the same pool of loans are not necessarily equal. Typically, the pool is sliced into “tranches” like a loaf of bread, with each slice carrying different features. The safest have first dibs on interest and principal earnings, or are the last in the pool to default if payments dry up. In exchange for safety, these pay the least. At the other extreme are tranches that pay the most but are the first to lose out when income stops flowing.

Still, despite the risks, many experts say non-agency securities are safer than they used to be.

“Since the financial crisis, issuers have been much more careful in choosing the collateral that goes into a non-agency MBS, sticking to plain vanilla mortgage products and borrowers with good credit profiles,” says David Reiss, a Brooklyn Law School professor who studies the mortgage market.

“It seems like the Wild West days of the mortgage market in the early 2000s won’t be returning for quite some time because issuers and investors are gun shy after the Subprime Crisis,” Reiss says. “The regulations implemented by Dodd-Frank, such as the qualified residential mortgage rule, also tamp down on excesses in the mortgage markets.”

New Housing and Displacement

Lsanburn

The Institute of Governmental Studies at UC Berkeley has issued a research brief, Housing Production, Filtering and Displacement: Untangling the Relationships. It opens,

Debate over the relative importance of subsidized and market-rate housing production in alleviating the current housing crisis continues to preoccupy policymakers, developers, and advocates. This research brief adds to the discussion by providing a nuanced analysis of the relationship between housing production, affordability, and displacement in the San Francisco Bay Area, finding that:

• At the regional level, both market-rate and subsidized housing reduce displacement pressures, but subsidized housing has over double the impact of market-rate units.

• Market-rate production is associated with higher housing cost burden for low-income households, but lower median rents in subsequent decades.

• At the local, block group level in San Francisco, neither market-rate nor subsidized housing production has the protective power they do at the regional scale, likely due to the extreme mismatch between demand and supply.

Although more detailed analysis is needed to clarify the complex relationship between development, affordability, and displacement at the local scale, this research implies the importance of not only increasing production of subsidized and market-rate housing in California’s coastal communities, but also investing in the preservation of housing affordability and stabilizing vulnerable communities. (1)

This brief takes on an important subject — the relationship between new housing and displacement — and concludes,

There is no denying the desperate need for housing in California’s coastal communities and similar housing markets around the U.S. Yet, while places like the Bay Area are suffering from ballooning housing prices that are affecting people at all income levels, the development of market-rate housing may not be the most effective tool to prevent the displacement of low-income residents from their neighborhoods, nor to increase affordability at the neighborhood scale.

Through our analysis, we found that both market-rate and subsidized housing development can reduce displacement pressures, but subsidized housing is twice as effective as market-rate development at the regional level. It is unclear, however, if subsidized housing production can have a protective effect on the neighborhood even for those not fortunate enough to live in the subsidized units themselves.

By looking at data from the region and drilling down to local case studies, we also see that the housing market dynamics and their impact on displacement operate differently at these different scales. Further research and more detailed data would be needed to better understand the mechanisms via which housing production affects neighborhood affordability and displacement pressures. We know that other neighborhood amenities such as parks, schools, and transit have a significant impact on housing demand and neighborhood change and it will take additional research to better untangle the various processes at the local level.

In overheated markets like San Francisco, addressing the displacement crisis will require aggressive preservation strategies in addition to the development of subsidized and market-rate housing, as building alone won’t protect specific vulnerable neighborhoods and households. This does not mean that we should not continue and even accelerate building. However, to help stabilize existing communities we need to look beyond housing development alone to strategies that protect tenants and help them stay in their homes. (10-11, footnote omitted)

The brief struggles with a paradox of housing — how come rents keep going up in neighborhoods with lots of new construction? The answer appears to be that the broad regional demand for housing in a market like the Bay Area or New York City overwhelms the local increase in housing supply. The new housing, then, just acts like a signal of gentrification in the neighborhoods in which it is located.

If I were to criticize this brief, I would say that it muddies the waters a bit as to what we need in hot markets like SF and NYC: first and foremost, far more housing units. In the absence of a major increase in supply, there will be intense market pressure to increase rents or convert units to condominiums. Local governments will have a really hard time overcoming that pressure and may just watch as area median income rises along with rents. New housing may not resolve the problem of large-scale displacement, but it will be hard to address displacement without it. Preservation policies should be pursued as well, but the only long-term solution is a lot more housing.

I would also say that the brief elides over the cost of building subsidized housing when it argues that subsidized housing has twice the impact of market-rate units on displacement. The question remains — at what cost? Subsidized housing is extremely expensive, often costing six figures per unit for new housing construction. The brief does not tackle the question of how many government dollars are needed to stop the displacement of one low-income household.

My bottom line: this brief begins to untangle the relationship between housing production and displacement, but there is more work to be done on this topic.
