The Harvard Joint Center for Housing Studies has released a working paper, Rental Housing: An International Comparison. The abstract reads,
This report compares rental housing in 12 countries in Europe and North America, using individual records from household surveys. Differences in housing characteristics, conditions, and costs across countries reflect a number of factors, including demographics, geography, culture, and government policies. A lack of comparable data can make international comparisons difficult to execute, but such analysis is valuable for understanding and contextualizing differences in affordability and other characteristics of renter households and housing.
The analysis revealed the US, along with Spain, as notably unaffordable for renter households, based on a number of measures. The greater apparent cost burdens reflected a variety of factors, including differences in characteristics of the housing stock and differences in tax burdens, as well as measurement problems.
However, two major influences – differences in the size and availability of housing allowances and the degree of income inequality – emerged as the main drivers of differences in housing affordability. The effects of supply-side factors such as the extent of social housing supply, supply subsidies, and rent controls were unclear, due to problems with the identification and description of below-market rentals in the household survey data.

The housing stock and political context is so different among countries, but this type of analysis is still very useful and can offer valuable lessons to the United States:
One factor that appears to contribute to the pervasive affordability problems in the US is the degree of income inequality. That is not a feature of the housing market per se, but there may be opportunities to address the consequences of income inequality through appropriate housing policies.
Other countries have devoted more resources to ameliorating the problems of unaffordable housing. The US provides fairly generous housing benefits to only a small share of needy households. In the UK, a broadly available system of housing allowances offsets what would otherwise be a much more severe affordability problem than exists in the US. In other countries, affordable rental housing supplied by governments or nonprofits helps to address affordability issues, although the efficiency of that practice, relative to the provision of housing allowances, has been questioned, as it has been in the US. The EU-SILC data used in this analysis did not adequately identify or describe below-market-rate housing, making it impossible to adequately assess the effects of such housing.
The somewhat larger size and perhaps higher quality of units in the US rental stock also affects relative affordability, although relative quality and its effect on cost differences are difficult to assess using the available data. The large share of single-family detached rentals in the US reflects preferences, the demographic mix among renters, land availability, etc., but it could also reflect zoning and other regulations limiting the supply of less expensive multifamily rentals. It is hard to imagine that regulations are more stringent in the US than in some of the more dirigiste nations of Europe, but regulations elsewhere may dictate, rather than constrain, density and cost reductions. The size and quality of the housing occupied by low-income renters in the US reflect the fact that most of those units were originally built for owner occupancy or for higher-income renters. That’s probably true in other countries as well. Whether the extent of such filtering is greater or less in various countries is perhaps worth exploring in the future. (37-38)
Income inequality, housing subsidies and land use reform — the report hits on a trifecta of key issues that housing policy should be dealing with. While I do not see much of an appetite for major reform of the first two items in today’s political climate, there might be support for some loosening of land use restrictions on housing construction. I wonder if there is some room for movement on that third front. Can local jurisdictions be incentivized by the federal government to build more housing?
