Understanding How Inequality in the Distribution of Income Affects Health

Research on the determinants of health has almost exclusively focused on the individual but it seems clear we cannot understand or improve patterns of population health without engaging structural determinants at the societal level. This article traces the development of research on income distribution and health to the most recent epidemiologic studies from the USA that show how income inequality is related to age-adjusted mortality within the 50 States. (r 520.62, p 5 0.0001) even after accounting for absolute levels of income. We discuss potential material, psychological, social and behavioral pathways through which income distribution might be linked to health status. Distributional aspects of the economy are important determinants of health and may well provide one of the most pertinent indicators of overall social well-being.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66686/2/10.1177_135910539700200303.pd

Immigrant Earnings Adjustment: The Impact of Age at Migration

Human capital theory, in conjunction with Chiswick's (1978) and Borjas' (1998) work, implies the post-migration path of immigrant earnings is likely to depend on the age at migration. An adaptation of Borjas' (1998) model of immigrant wage determination is presented which predicts, for a given stock of human capital at the point of migration, lower initial earnings for younger arrivals, but faster earnings growth with time in the destination country. Empirical tests on data for Australian immigrants provide qualified support for the hypothesis that initial wages are, ceteris paribus, increasing in age at migration and the rate of wage growth is decreasing in age at migration.
