The efficiency-equity trade-offs in public service delivery may be influenced by the dependency of local governments on their own resources rather than inter-governmental grants. School districts in the United States are expected both to produce human capital efficiently and to provide educational opportunity equally. To ascertain school district trade-offs, we estimate effects of revenue source on student performances in math and reading. Achievement is estimated from 225,000 observations weighted to be district representative. Estimates are made with OLS [ordinary least squares], geographic discontinuity models exploiting differences at state borders, and 2SLS [two-stage least squares] models that use changes in housing prices as an instrument. For every 10 percent increase in local revenue share, achievement increases by a sizeable 0.02 to 0.06 standard deviations. Gains for students from low socio-economic backgrounds are about half those from higher ones. Both voice and exit channels moderate the efficiency-equity trade-off. Implications for federalism and state policy are discussed.
