Does compulsory schooling affect health? Evidence from ambulatory claims data

Education and medication use later in life and the role of intelligence

We investigate the association between education and disease-specific medications in old age, prescribed by medical doctors, accounting for confounders and how this association is shaped by intelligence. We use administrative data on men including prescribed medication records. To account for endogeneity of education we estimate a structural model, consisting of (i) an ordered probit for educational attainment, (ii) a Gompertz mortality model for survival up to old age, (iii) a probit model for prescribed medications in old age, (iv) a measurement system using IQ tests to identify latent intelligence. The results suggest a strong effect of education on prescribed medications for most medications, except for prescribed medication for cardiac diseases and for depression and anxiety.

Mental health effects of education

We analyze the role of education as a determinant of mental health. To do this, we leverage the age-specific exposure to an educational reform as an instrument for years of education and find that the treated cohorts gained more education. This increase in education had an effect on mental health more than 2 decades later. An extra year of education led to a lower likelihood of reporting any symptoms related to depression (11.3%) and anxiety (9.8%). More educated people also suffered less severe symptoms - depression (6.1%) and anxiety (5.6%). These protective effects are higher among women and rural residents. The effects of education on mental well-being that we document are potentially mediated through better physical health, improved health behavior and knowledge, and an increase in women's empowerment.
