Do children in private Schools learn more than in public Schools? Evidence from Mexico

In this study I try to answer the question whether private schools do better in the human capital accumulation process than public schools in Mexico. The analysis is based on panel data including out-of-school cognitive skill tests, which allows dealing with some potential endogeneity problems due to the selection process into private schools. The absolute advantage of private school graduates in cognitive skills disappears once controlling for the selection bias, where no positive eect is found anymore.
