Abstract
Summary: We analyse the effect of income on mortality in Austria by using administrative social security data. To tackle potential endogeneity concerns arising in this context, we estimate time invariant firm-specific wage components and use them as instruments for actual wages. Although we find quantitatively small yet statistically significant effects in our naive least squares estimations, instrumental variables regressions reveal a robust zero effect of income on 10-year death rates for workers aged 40–60 years, both in terms of coefficient magnitude and narrow width of confidence intervals. These results are robust to various sample specifications and both linear and non-linear estimation methods.
