A caveat of our results is that we focus on **highly localized** effects, where demand effects dominate, while regenerations may still contribute (albeit modestly) to city-wide affordability through broader supply effects. 9/9

Implications:
1️⃣ Conversion to mixed-income housing while preserving the public housing stock can mitigate the negative effects of traditional public housing on neighborhoods
2️⃣ By improving amenities, it can also make housing less affordable in the **very local** vicinity.
8/9

Interestingly, we find that regenerations that add more market-rate housing actually see larger local price increases. This suggests that (in our context) demand effects from incoming higher-income HHs outweigh local supply effects from additional market-rate units. 7/9

Mechanisms:
- Eyesore removal: half of price effects occur within 50m of walking distance.
- Socioeconomic shifts: higher-income HHs move in, no evidence of decrease in low-income HHs
- Crime: drops up to 8% near regenerations, can explain at most 1/3 of price increase
6/9

By comparing housing units near the regenerations to units located farther away, we show that:
- Prices (+14%) & rents (8%) go up substantially within 100m of regenerated estates
- Effects fade with distance and disappear beyond 300m.
5/9

Theory is ambiguous:
- Supply effect: more market-rate housing could lower nearby prices.
- Demand effect: removing an eyesore, attracting higher-income households, and reducing crime could raise them by improving amenities.
4/9

These regenerations on average roughly preserved the number of public housing units but added a similar number of market-rate units on-site (⬆️housing supply).

*Did this approach improve neighborhoods, and what happens to nearby house prices and rents?* 3/9

Like in the US, large public housing "estates" in the UK had been associated with poor conditions, high crime rates, and low housing values.

In response, London started a wave of estate "regenerations” in the 2000s, replacing old estates with new mixed-income developments. 2/9

We study the impact of converting distressed public housing into mixed-income housing on local housing markets. 🧵👇1/9

Knocking It Down and Mixing It Up: The Impact of Public Housing Regenerations Abstract. Partly due to their negative effects on surrounding neighborhoods, some countries have been replacing distressed public housing developments with mixed-income housing. We study the impact of such policies on local housing markets in London, U.K., where several public housing developments were demolished and rebuilt while adding market-rate units on-site. We show that these ‘regenerations’ increase nearby house prices and rents, consistent with strong demand effects outweighing supply effects from additional market-rate housing in the immediate vicinity. We provide suggestive evidence that these effects are driven by regenerations removing an eyesore, attracting higher-income households, and reducing nearby crime.

Replacing distressed public housing with mixed-income housing raises local prices and improves local amenities. Just Accepted new paper by Hector Blanco and Lorenzo Neri Bluesky: @hectorblanco.bsky.social @loreneri.bsky.social zurl.co/dAvES

Working on a new R package. Looking for applications that do two things:

1. DID with y to show an effect
2. DID with X to show a possible “mechanism” of why treatment changed y
