An MIT economist looks at the relationship between gentrification and a shortage of cheaper housing:
Unsurprisingly, the geography of a place and the community residing there are linked. Along the most measurable dimensions, richer people tend to live in places with attractive geographies. Conversely, places with undesirable attributes like industrial or transportation pollution, poor access to jobs, and uninviting climates are usually left for the poorest and most marginalized.
Usually—but not always. Occasionally, physically attractive locations come to be occupied by low-income communities, immigrant communities, black communities. Neighborhoods like these are ripe for gentrification. Changes in labor markets, large investments by public or private institutions, or even just changing preferences among the wealthy move these neighborhoods into the sight lines of richer people, and then they gentrify.
The housing shortage, meanwhile, is a region-wide round of musical chairs, in which the winners sat down before the music even stopped. Whereas gentrification reshuffles which communities occupy which parts of the city, the housing shortage can operate at the scale of cities and regions as well as neighborhoods…
Policies introduced to fight gentrification—rent control and tenant protections—may ameliorate the effects of neighborhood change, but they won’t build new homes. We must allow new construction somewhere, despite the changes this will bring. Of course, we must do so in a way that avoids gentrification.
Four quick thoughts on this argument:
1. This reminds me of my post from the other day comparing the perspective that there is not enough housing and there is plenty of housing but it is not cheap enough. This piece suggests there are multiple housing issues at work and policies might tackle one particular issue and not others (or even make other housing issues worse).
2. Does the multiplicity of housing issues require that Americans prioritize which issue matters to them most? If middle-class people want cheaper housing, that will lead to different approaches (public policies, legislation, urban planning, decisions by developers, etc.) compared to a consensus that gentrification is not desirable. Historically, Americans have tended to prioritize housing for the middle-class (broadly defined) at the expense of housing for the poor or homeless.
3. To truly address all of these issues, metropolitan-wide approaches are needed. Individual neighborhoods or municipalities are often left to tackle these on their own even though decisions by nearby neighborhoods or municipalities have significant effects on their housing.
4. Additionally, a comprehensive housing policy is needed, not just one that tackles the most important or noisiest issue at the moment. On one hand, many Americans would not want the government to become involved in such issues even as the government has promoted suburban homeownership for roughly a century.
