When the demand for housing rises, which kinds of neighborhoods respond by building more homes, and which just get more expensive? Nathaniel Baum-Snow joins to discuss his research on the different responses of urban, suburban, and exurban neighborhoods, and the many forms “supply” can take.

We often talk about residential segregation by race or income, but we rarely explore it in the literal sense — as in segregation of residences: of one kind of housing from another. Ann Owens joins to discuss her research on how segregation manifests itself in our built environment in cities and neighborhoods across the U.S.

Black households make up a disproportionate share of rent assistance recipients. Andrew Fenelon discusses how a “two-tiered approach to housing support" favoring white homeowners helped create the disparity.

Before the 2000s, French real estate developers were prohibited from building social housing. Today, they build more than half of it. Julie Pollard shares how two seemingly unrelated policies came together to make this rapid shift possible.

For this episode, we take a trip to Tokyo to learn from the successes and shortcomings of Japanese housing policy. Known for high rates of production — Tokyo builds five times more housing than California, per capita — and relatively affordable housing, Japan also struggles with poor maintenance and rapid degradation of its buildings. Professor Jiro Yoshida of Pennsylvania State University and the University of Tokyo joins us to talk about the unique demographic, economic, and geographic conditions that led to Japan’s current housing context, and the underrecognized influence of depreciation and tax policy in the choices we make about where and how to live.

What makes people more or less supportive of dense housing in their communities? David Kaufmann and Michael Wicki surveyed 12,000 residents in six of the largest U.S. and European cities to find out.

Subsidized affordable housing development reduces costs for lower-income households directly. It also reduces costs indirectly, by increasing the overall supply of housing — or does it? Michael Eriksen joins to discuss the issue of “crowd out” in affordable housing production.
