Accounting for the effect of health on economic growth

"I use microeconomic estimates of the effect of health on individual outcomes to construct macroeconomic estimates of the proximate effect of health on GDP per capita. I use a variety of methods to construct estimates of the return to health, which I combine with cross-country and historical data on several health indicators including height, adult survival, and age at menarche. My preferred estimate of the share of cross-country variance in log income per worker explained by variation in health is 22.6%, roughly the same as the share accounted for by human capital from education, and larger than the share accounted for by physical capital. I present alternative estimates ranging between 9.5% and 29.5%. My preferred estimate of the reduction in world income variance that would result from eliminating health variations among countries is 36.6%"--National Bureau of Economic Research web site.
