We use store-specific data for a UK supermarket chain to estimate the impact of planning on store output. Exploiting the variation in policies between England and other UK countries, we isolate the impact of Town Centre First (TCF) policies introduced in England. We find they directly reduced output by forcing stores onto less productive sites. We estimate TCF policies imposed a loss of output of 32% on a representative store opening after their rigorous implementation in 1996. Additionally, we show that, household numbers constant, more restrictive local authorities have fewer stores and lower chain sales within their areas.
