This thesis presents a meta-analysis of the competitive effects of school choice on student academic achievement. Synthesising 2,591 estimates from 61 stud- ies spanning voucher programs, charter schools, and open-enrollment policies across multiple countries, we apply the full suite of modern meta-analytic meth- ods standard in economics. The unweighted mean partial correlation coeffi- cient is 0.010, suggesting a negligible association between school competition and achievement. Formal tests provide evidence consistent with publication bias and selective reporting. After correcting for these distortions, the effect is indistinguishable from zero across all specifications, with several methods yielding slightly negative point estimates. Bayesian and frequentist model av- eraging identify key drivers of heterogeneity: the use of basic estimation meth- ods, lower-income country settings, and the distinction between pure competi- tion effects and total effects that conflate competition with participation gains. Among the subset of estimates that could be classified, isolating the pure com- petition channel produces smaller or negative estimates. The bias-corrected estimate evaluated at sample-average study characteristics is −0.102, which is statistically insignificant and represents a conservative...
