There is a strong, positive and well-documented correlation between education and health outcomes. There is much less evidence on the extent to which this correlation reflects the causal effect of education on health - the parameter of interest for policy. In this paper we attempt to overcome the difficulties associated with estimating the causal effect of education on health. Our approach exploits two changes to British compulsory schooling laws that generated sharp differences in educational attainment among individuals born just months apart. Using regression discontinuity methods, we confirm that the cohorts just affected by these changes completed significantly more education than slightly older cohorts subject to the old laws. However, we find little evidence that this additional edu...

It is widely documented that U.S. students score below their OECD counterparts on international achievement tests, but it is less commonly known that ultimately, U.S. native adults catch up. In this paper, we explore institutional explanations for differences in the evolution of literacy over young adulthood across wealthy OECD countries. We use an international cross-section of micro data from the International Adult Literacy Survey (IALS); these data show that cross-country differences in the age profile of literacy skills are not due to differences in individual family background, and that relatively high rates of university graduation appears to explain a good part of the U.S. "catch up." The cross-sectional design of the IALS prevents us from controlling for cohort effects, but we ...
