Tiebout theorizes that local public services are provided more efficiently if costs are paid out of local revenues rather than by inter-governmental grants. But if local politics is not as pluralistic as Dahl has argued, citizens of higher socio-economic status will exercise greater influence, resulting in higher inequalities in service provision. We use administrative data to estimate the impacts of local revenue shares on individual performance of a nationally representative sample of over 140,000 U.S. eighth graders in math and reading. Causal effects are estimated with geographic discontinuity models and 2SLS models that use change in housing prices as an instrument. For every 10 percent increase in local revenue share, students perform about 0.05 standard deviations higher. Gains from local funding are less for disadvantaged students. Local financing affords better education for all but widens achievement gaps.
