Three Interesting Things for W/C 2025-07-13
1. Konstantin A. Kholodilin – “Rent control effects through the lens of empirical research: An almost complete review of the literature”
🏠 Scope check: Surveys almost every empirical study since WWII, spanning 80 years, 30+ countries and every major rent-control episode.
📊 Consensus pattern: Strong evidence that controls cap in-place rents short-term but shrink the controlled stock and distort new construction.
(-) indicates papers finding a negative effect, (0) no effect, and (+) a positive effect. ⚖️ Equity twist: Benefits flow mainly to long-term tenants with higher socio-economic status, often crowding out newer or poorer entrants.
🏗️ Collateral damage: Strong consensus on lower new-build activity, poorer maintenance, and stickier tenant mobility - undermining long-run welfare gains.
