Bergh, A. and T. Nilsson (2010). "Good for living? On the relation between globalization and life expectancy." World Development 38(9): 1191-1204.
This paper analyzes the relationship between three dimensions (economic, social, and political) of globalization and life expectancy using a panel of 92 countries covering the 1970–2005 period. Using different estimation techniques and sample groupings, we find that economic globalization has a robust positive effect on life expectancy, even when controlling for income, nutritional intake, literacy, number of physicians, and several other factors. The result also holds when the sample is restricted to low-income countries only. In contrast, political and social globalization have no such robust effects.
