The Social Costs of Smart Growth (Urban Containment)

“Soaring” land and house prices “certainly represent the biggest single failure” of smart growth, which has contributed to an increase in prices that is unprecedented in history. While this finding could well have been from our NCPA Policy Report, The Housing Crash and Smart Growth, they were actually from one of the world’s leading urbanologists, Sir Peter Hall, in the classic work he led on urban containment planning (a principal strategy of smart growth) 40 years ago. Hall led an evaluation of the effects of the British Town and Country Planning Act of 1947 (The Containment of Urban England) between 1966 and 1971. The principal purpose of the Act had been urban containment, using the land rationing strategies of today’s smart growth, such as urban growth boundaries and comprehensive plans that forbid development on large swaths of land that would otherwise be developable.

The Economics of Urban Containment (Smart Growth): The findings of Hall and his colleagues were just the beginning. A Labour Government report in the mid-2000s showed that housing affordability had been even further retarded by the policies. The author, Kate Barker was a member of the Monetary Policy Committee of the Bank of England, which like America’s Federal Reserve Board, is in charge of monetary policy. Among other things, the Barker Reports on housing and land use found that urban containment had driven the price of land with “planning permission” to 250 times (per acre) that of comparable land on which planning was prohibited. Under normal circumstances comparable land would have similar value.

The economic research is by no means limited to Hall and Barker, rather it is overwhelming. From left to right, economists have shown stronger land use regulation tends to raise land (and thus house) prices. Just like water tends to run downhill, prices tend to rise when supply is restricted, all things being equal. This is why the world so nervously watches OPEC fearing the supply constraints that generate higher oil prices. Moreover, there can be no other reason for the price differentials virtually across the street that occur in smart growth areas. Dr. Arthur Grimes, Chairman of the Board of New Zealand’s central bank (the Reserve Bank of New Zealand), found the differential on either side of Auckland’s urban growth boundary at 10 times, while we found an 11 times difference in Portland across the urban growth boundary.

House Prices in America: The Historical Norm: Since World War II, median house prices in US metropolitan areas have generally been between 2.0 and 3.0 times median household incomes (a measure called the Median Multiple). This included California until 1970 (Figure 1). After that, housing became unaffordable in California, averaging nearly 1.5 times that of the rest of the nation during the 1980s and 1990s (adjusted for incomes). Even after the huge price declines from the peak of the bubble, house prices remain artificially high in Los Angeles, San Francisco, San Diego and San Jose, at double historic norms.

William Fischel of Dartmouth University examined a variety of justifications for the disproportionate rise of California housing prices and dismissed all but more restrictive land use regulation. He noted that “growth controls (restrictive land use regulations) have the undesirable effect of raising housing prices.” Throughout the rest of the nation, more restrictive land use regulations have been present in every market where house prices rose substantially above the historic Median Multiple norm, even during the housing bubble. No market without smart growth has ever reached these price heights.

Setting Up for the Fall: Excessive Cost Increases in Smart Growth Markets: The Housing Crash and Smart Growth, published by the National Center for Policy Analysis, examined the causes of house price increase during the housing bubble. The analysis included all metropolitan areas with more than 1,000,000 population. It focused on 11 metropolitan areas in which the greatest cost increases occurred (the 11 “ground zero” markets, Los Angeles, San Francisco, San Diego, San Jose, Sacramento, Riverside – San Bernardino, Las Vegas, Phoenix, Tampa – St. Petersburg, Miami and the Washington, DC metropolitan areas), comparing them to cost increases in the 22 metropolitan areas with less restrictive land use regulation.

• Less Restrictively Regulated Markets: In the less restrictively regulated markets, the value of the housing stock rose approximately $560 billion, or 28 percent from 2000 to the peak of the bubble. In nearly all of these markets, the Median Multiple remained within the historical range of 2.0 to 3.0 and none approached the high Median Multiples that occurred in the “ground zero” markets.

• Ground Zero Markets The value of the housing stock rose $2.9 trillion from 2000 to the peak of the bubble in the “ground zero” markets, all of which have significant land use restrictions. The 112 percent increase in the “ground zero” markets was four times that of the less restrictively regulated markets. The Median Multiple rose to unprecedented levels in each of the “ground zero” markets, peaking at from 5.0 to more than 11.0, double to four times the historic norm.

The 28 percent increase in relative house value that occurred in the less restrictively regulated markets (those without smart growth) is attributed to the influence of loosened lending standards. The excess above 28 percent, which amounts to $2.2 in the “ground zero” markets is attributed to smart growth.

The underlying demand for housing was substantial in some of the less restrictively markets, which is illustrated by the strong net domestic migration to metropolitan areas such as Atlanta, Austin, Dallas – Fort Worth, Houston, Raleigh and San Antonio. At the same time, some more restrictive markets (smart growth) that hit historically experienced strong demand were experiencing huge domestic outmigration, indicating little in underlying demand. This includes Los Angeles, San Francisco, San Diego and San Jose. Demand, however is driven upward in more restrictively metropolitan areas by speculation which, according to the Federal Reserve Bank of Dallas is attracted by supply constraints.

The Fall: Smart Growth Losses

The largest house price drops occurred in the markets that had experienced the greatest cost escalation. This is not only to be expected from a perspective of probability, but is also indicative of the greater price volatility of more restrictively regulated markets as shown by economists Edward Glaeser and Joseph Gyourko. The “ground zero” markets, with only 28 percent of the owner occupied housing stock, accounted for 73 percent of the pre-crash losses ($1.8 trillion). Thus, much of the cause of the housing crash, which most analysts date from the Lehman Brothers bankruptcy (September 15, 2008), can be attributed to these 11 metropolitan areas.

By contrast, the 22 less restrictively regulated markets accounted for only six percent ($0.16 trillion) of the pre-crash losses. These 22 markets represented 35 percent of the owned housing stock (Figure 3).

If the losses in the ground zero markets had been limited to the rate in the less restrictively regulated markets (the estimated impact of cheap credit), lenders would have lost $1.6 trillion less. The Great Financial Crisis might not have been so “Great.”

Economic Denial and Acknowledgement: Dr. Hall noted that English planners denied the connection between the unprecedented house price increases and urban containment. The same economic denial is found among smart growth advocates today. This is perhaps to be expected, because, as Hall noted 40 years ago, an understanding of the longer term consequences could have undermined support for urban containment.

To their credit, some advocates recognize that smart growth raises house prices. The Costs of Sprawl – 2000¸ a volume largely sympathetic to smart growth, also indicates that urban containment strategies can raise housing prices. The only question is how much smart growth raises house prices. The presence of urban containment policy is the distinguishing characteristic of metropolitan markets where prices have escalated well beyond the historic norm.

The Social Costs of Smart Growth: Moreover, the social impacts of smart growth are by no means equitable. Peter Hall says that the “less affluent house – owner … has paid the greatest price for (urban) containment.” He continues: “there can be little doubt about the identity of the group that has got the poorest bargain. It is the really depressed class in the housing market: the poorer members of the privately – rented housing sector.” Finally, Hall laments the fact that the result contravenes the “ideal of a property owning democracy.”

Hall’s four decades old concern strikes a chord on this side of the Atlantic. Just last week, a New York Times/CBS News poll found that nine out of ten respondents associated property ownership in the form of a home with the American Dream.

  1. Does Smart growth, properly understood, refer only to land use, or does it encompass other aspects of construction like local building codes?

  2. Shelley says:

    More cities are enacting Agenda 21 policies which require migrating more people into condensed areas; ripping up streets to enlarge water lines and sewage lines, etc. It’s a sorry state of affairs.
