This article investigates the provision of police and education servic
es using a new method of indexing quantities of local public services
that isolates movements in shadow prices and quantities in expenditure
data. Demand equations for two public characteristics (the crime safe
ty rate and high school reading test pass rates) and two categories of
expenditures (education and police services) are simultaneously estim
ated for New Jersey municipalities. The relationship between public se
rvices and public characteristics is estimated and both the ''own'' an
d the ''cross''-effects of public services are found to be empirically
significant. Increases in expenditures between 1982 and 1983 are foun
d to largely reflect increases in quantities of education services and
in prices of police services.
