Does Education Reduce Blood Pressure? Estimating the Biomarker Effect of Compulsory Schooling in England

Abstract

This paper is the first of its kind to estimate the exogenous effect of schooling on reduced blood pressure and the incidence of hypertension. Using the changes of the minimum school-leaving age in the United Kingdom from age 14 to 15 in 1947, and from age 15 to 16 in 1973, as instruments, the IV-probit estimates imply that completing an extra year of schooling reduces the probability of developing subsequent hypertension by approximately 5%-11% points. The correct estimates of the LATE for schooling indicate the presence of a large and negative bias in the least square/probit estimates of schooling-health relationship.blood pressure; compulsory schooling; biomarker; IV; hypertension; health
