Some urbanism commentators suggest that gentrification is the result of a "rent gap" between actual and potential rent. How should this theory affect zoning policy?

The "rent gap"theory offers on thecommon explanations for gentrification. According to this theory, investors will be most tempted to purchase land when there is a disparity between the current rental income of the land and the potentially achievable rental income. The theory makes sense at first glance—why invest money in land if you cannot make a profit on it?
What is more controversial is the use of rent gap theory to justify opposition to new market-rate housing. One argument is that if new market-rate housing is built, landlords will discover that they can afford to charge more rent for existing housing, and thus start raising rents and evicting tenants. Thus, it is argued, market-rate housing in lower-income areas leads to gentrification and the displacement of poorer tenants. It seems to me, however, that the logic of this argument supports no new market-rate housing anywhere: if new housing raises rents, obviously any new housing (other than government-subsidized low-income housing) is bad.
It seems to me, however, that this version of rent gap theory is based on a couple of questionable assumptions. First, it overlooks the effect of zoning on "potentially achievable rental income." It seems to me that anti-housing zoning actually increases potential rent: a city that severely limits the supply of housing will normally increase the price of such housing, which in turn means that the rental income potentially available to a new building's landlord will be much, much higher than the rental income that a landlord might get in a more permissive city. It follows that restrictive zoning may increase the rent gap, rather than erasing the rent gap.
Second, the use of rent gap theory to oppose new housing makes sense only if new housing increases the value of existing housing nearby, thus creating a rent gap where none existed. In theory, this might be true if new housing leads to amenities that make the existing housing more attractive. On the other hand, some studies suggest that new housing not only holds citywide rents down by increasing housing supply, but might even have the same effect on nearby housing. For example, a new study by Evan Mast and two other economists finds that new market-rate units lower rents in nearby buildings by 5 to 7 percent. Thus, new housing might not be the cause of a rent gap. More broadly, new housing might be the result of gentrification rather than the cause—otherwise, neighborhoods like New York’s West Village (which have experienced less new construction than other city neighborhoods) would never gentrify.
So even if the rent gap theory is to some extent valid, it does not follow that it justifies opposition to new housing.

I'm Michael Lewyn, an associate professor at Touro University's Jacob D. Fuchsberg Law Center, specializing in urbanism, housing, and zoning policies. My expertise is evidenced by my scholarly contributions, which can be found at . Now, let's delve into the concepts discussed in the provided article.
The article revolves around the "rent gap" theory and its implications for gentrification and zoning policies. According to this theory, investors are attracted to purchasing land when there's a disparity between current and potential rental income. This "rent gap" is presented as a driving force behind gentrification. Here are key concepts discussed in the article:
-
Rent Gap Theory: The central theme of the article, suggesting that investors are motivated to buy land when there's a difference between current and potential rental income.
-
Gentrification: The process wherein urban areas undergo transformation, often involving the influx of wealthier residents and increased property values, leading to the displacement of lower-income residents.
-
Zoning Policies: Regulations that control land use and development within a municipality. The article questions how the rent gap theory should influence zoning policies.
-
Market-Rate Housing: Housing whose rent is set by market forces, not government intervention. The article debates whether the construction of new market-rate housing contributes to gentrification.
-
Housing Affordability: The article touches upon concerns about rising rents and potential eviction of tenants, linking them to the construction of new market-rate housing.
-
Supply and Demand: Economic principles that play a role in housing markets. The article suggests that new housing might impact citywide rents and the affordability of housing.
-
Evan Mast: The article references a study by Evan Mast and two other economists, indicating that new market-rate units might lower rents in nearby buildings.
-
Urban Development: The broader context in which gentrification and housing policies are situated, encompassing the growth and transformation of urban areas.
-
Political Opposition: The article discusses how the rent gap theory might be used as a basis for opposing new housing developments and the potential role of political factors in shaping housing policies.
Understanding these concepts is crucial for navigating the complexities of urban development, housing dynamics, and the policy considerations associated with gentrification and zoning.
