EXTRA: Why Rent Control Doesn’t Work (Update)

Episode Summary

Executive Summary: This bonus episode revisits rent control amid worsening housing affordability. It argues that while rent control can protect incumbent tenants in the short run, decades of research show it reduces housing supply, discourages investment, freezes mobility, and can worsen citywide affordability. The episode contrasts these costs with public support for regulation and explores alternative approaches like supply expansion, vouchers, and smarter tax/zoning policy.

Main Topics: Why rent control is back on the policy agenda (Priority: 5/5): Dubner frames the episode as a response to rising post-2019 rents, citing national rent growth and new federal proposals to cap increases. The renewed political interest is driven by housing crises in expensive cities. Economic case against rent control (Priority: 5/5): Economists like Ed Glaeser and Milton Friedman argue rent control is a blunt price control that misallocates scarce housing, discourages new construction, and freezes people in units that no longer fit their needs. Empirical evidence from San Francisco (Priority: 5/5): Rebecca Diamond summarizes research using administrative address-history data to show rent control keeps some tenants in place, reduces displacement, especially for minorities, but also cuts rental supply as landlords convert, sell, or redevelop buildings. What happens when rent control is removed (Priority: 4/5): Evidence from Cambridge, Massachusetts suggests deregulation leads landlords to renovate and invest, raises nearby property values, and may even reduce crime—showing that repeal can improve supply and quality, though not necessarily affordability immediately. Political appeal vs. long-term costs (Priority: 4/5): The episode explains why rent control remains popular with Democrats and renters: benefits are immediate and visible, while market-wide harms are diffuse, delayed, and easier for politicians to ignore or dismiss. Commercial rent regulation and empty storefronts (Priority: 3/5): The show turns to proposals for commercial rent protections in New York, including the Small Business Job Survival Act, and notes economists are skeptical because similar incentives could worsen vacancies and distort leasing decisions. Alternative housing policy levers (Priority: 5/5): The discussion broadens to vouchers, property taxes, zoning reform, and land-use rules. Economists argue the most natural path to affordability is more supply—especially easier as-of-right development in high-demand cities.

Key Arguments: Rent control helps incumbent tenants by limiting rent hikes, but it does so by shrinking supply and reducing mobility, which harms future renters and overall affordability. Landlords respond rationally to rent caps by converting units, selling to owner-occupants, redeveloping, or otherwise reducing rental stock, undermining the policy’s goal. The benefits of rent control are concentrated and immediate, while its costs are dispersed and delayed, making the policy politically attractive despite weak economic performance. Removing rent control can improve investment and neighborhood quality, but deregulation alone does not solve affordability when the underlying housing shortage remains severe. A better policy target is housing supply: more permissive zoning, less red tape, and targeted subsidies/vouchers rather than broad price caps. Commercial rent control is even less studied, and economists warn it could exacerbate vacancies by making landlords hold out for high-end tenants.

Data Points: National rent increase since Harvard report baseline: 26% - Rents have risen nationally since the prior Freakonomics episode, according to Harvard’s Joint Center for Housing Studies. Median rent increase since the 1990s: Doubled - U.S. median rent has doubled since the 1990s, outpacing inflation. New federal rent cap proposal: 5% annual cap for landlords with more than 50 units - The Biden administration pushed Congress to require this cap or risk loss of federal tax breaks. Rent-controlled tenants more likely to stay: 20% more likely to remain - San Francisco study finding after rent control expansion. Rental housing supply reduction: 15% - Landlords subject to rent control reduced rental housing supply through condo conversion, sales, or redevelopment. Long-run retention after expansion: About 10% still in the original apartment - Tenants from the 1994 San Francisco cohort were mostly no longer in the same unit 10–15 years later. Estimated annual welfare loss in New York: Over $500 million annually - Glazer and Lutmer’s analysis of misallocated bedrooms under New York rent control. New York rental stock: About 3.4 million apartment units - Approximate total apartment units in New York City. New York rent-stabilized units: Nearly 1 million - Portion of NYC units that are rent stabilized. Stockholm queue size (2019): 550,000 people - People waiting for an apartment in Stockholm at the time of earlier reporting. Stockholm queue size (updated): Over 800,000 people - Current number waiting for an apartment in Stockholm. Sweden population share waiting: 5% - Around 5% of Sweden’s population is waiting for housing in Stockholm’s queue. Sweden housing need estimate: 440,000 new homes - 2016 National Board estimate of homes needed before 2020. Manhattan retail vacancy: Up to 20% - Some parts of Manhattan reportedly have this share of retail space vacant or soon to be vacant. California rent cap: 5% plus inflation, max 10% - Current statewide limit on annual rent increases.

Pivotal Quotes: "Short of bombing, I know of no way to destroy a city that was more effective than rent control." — Assar Lindbeck (quoted via transcript): Used to underscore the classic economist critique of rent control and its role in housing shortages. "It's not a good way of allocating scarce space. It's not a good way of helping the downtrodden. It's a way that freezes a city and stops it from adjusting to changes." — Ed Glaeser: His concise argument against rent control as an inefficient and distortionary policy. "The thing that you really need to focus on is, how can I ensure that the landlord is getting a reasonable return... You really need to have a holistic look." — Vicki Bean: A call for rent regulation design that balances tenant protection with incentives to invest and build.

Implications: Rent control can shield current tenants but is unlikely to solve affordability without more supply. Future policy debates will hinge on whether cities prioritize immediate protection or long-run market incentives, zoning reform, and targeted aid.
