The reform in question markedly increased the jurisdiction size of some, but not all, local governments in Denmark. In the new, larger municipalities, we might have expected the political power of NIMBY homeowners to decline relative to the median voter or the growth machine.

But we find no sign of this! The municipalities that increased in jurisdiction size started to permit *much less market rate housing* after the reform, relative to the municipalities that did not increase in size. So why did less local control lead to fewer permits???
