We analyze the welfare effects and voting equilibrium with vouchers fo
r private schools. The analysis shows that vouchers, like tuition tax
credits [Martinello and West (1988); Frey (1983)], may improve the wel
fare of all families, including families whose children remain in publ
ic schools, if public educational quality is unchanged and publicly-fi
nanced educational expenditures decrease. Thus, voters will approve a
voucher only if it reduces taxes. When public educational quality is e
ndogenous, a voucher may increase quality by reducing the tax cost of
quality and will be approved if it reduce taxes at the pre-voucher pub
lic education level and increases quality. (C) 1998 Elsevier Science S
