Duke University, Stanford University and NBER Abstract This paper uses a computational general equilibrium model to analyze the impact of public school finance regimes on rates of private school attendance. The simulations are derived from a three-community model of low, middle and high income school districts (calibrated to New Jersey data), where each school district is composed of multiple types of neighborhoods that may vary in house quality as well as the level of neighborhood amenities and externalities. Households that differ in both their income and in the ability level of their children choose between school districts, between neighborhoods within their school district, and between the local public school or a menu of private school alternatives. Local public school quality within a district is endogenously determined by a combination of the average peer quality of public school attending children as well as local property and state income tax supported spending. Financial support (above a required state minimum) is set either by local majority rule given particular state aid programs, or by state majority rule under a fully state financed system. Finally, there exists the potential for a private school market composed of competitive schools that face production technologies similar to those of public schools but that set tuition and admissions policies to maximize profits. It is shown that, when viewed in this general equilibrium context, state intervention in locally financed systems can have somewhat unexpected and counterintuitive effects of the level of private school attendance.
