Data and Code for: Quantifying the Supply Response of Private Schools to Public Policies

School policies that cause a large demand shift between public and private schooling may cause some private schools to enter or exit the market. We study how the policy effects differ under a fixed versus changing market structure in the context of a public school funding reform in New York City. We find evidence of a reduction in private schools in response to the reform. Using a model of demand for and supply of private schooling, we estimate that 20% of the reform's effect on school enrollments came from increased private school exit and reduced private school entry.
