Does Ethnicity Matter for Access to Childhoodand Adolescent Health Capital in China? Evidence from the Wage-Height Relationship in the 2006 China Health and Nutrition Survey

This paper considers whether ethnicity conditions the return and access to health capital in China. Given that the wage-height relationship reflects the labor market earnings returns to childhood and adolescent health capital, differences in the labor market returns to height by ethnicity reflect ethnic differences in access to health capital during childhood and adolescence. We theoretically motivate the role of height in earnings by providing a Bioeconomic rationale for stature and height determining individual wages, and estimate height-augmented Mincerian earnings functions with data from the 2006 China Health and Nutrition Survey. Our results show that when the effects of unobserved genetic influences on adult height are accounted for, the labor market return on height is higher for Chinese ethnics. This suggests that in China there are ethnic disparities in access to the inputs that produce childhood and adolescent health capital.
