While there is no doubt that health is strongly correlated with education, whether schooling exerts a causal impact on health is not yet firmly established. We exploit Dutch compulsory schooling laws in a Regression Discontinuity Design applied to linked data from health surveys, tax files and the mortality register to estimate the causal effect of education on mortality. The reform provides a powerful instrument, significantly raising years of schooling, which, in turn, has a large and significant effect on mortality even in old age. An extra year of schooling is estimated to reduce the probability of dying between ages of 81 and 88 by 2-3 percentage points relative to a baseline of 50 percent. High school graduation is estimated to reduce the probability of dying between the ages of 81 and 88 by a remarkable 17-26 percentage points but this does not appear to be due to any sheepskin effects of finishing high school on mortality beyond that predicted lin early by additional years of schooling.
