Do skewed sex ratios among children promote parental smoking? Longitudinal evidence from rural China

摘要

China and some other Asian countries have experienced skewed sex ratios, triggering intense competition and pressure in the marriage market. Meanwhile, China has more smokers than any other country, with half of men smoke while few women smoke. Men are the major income earners in most Chinese families and thus bear much of the financial burden in preparation for children’s marriage. This paper investigates how a demographic factor – a large number of surplus men in the marriage market in China – affects their fathers’ smoking behavior. We utilize a household longitudinal survey as well as a random subsample of the China Population Census to examine fathers’ smoking in response to skewed sex ratios. Strikingly, fathers smoke more for families with a son living in counties with higher sex ratios. In contrast, those with a daughter do not demonstrate this pattern. Coping with the marriage market pressure is a most plausible pathway linking skewed sex ratios and intense smoking among fathers. Considering worsening sex ratios and highly competitive marriage market in the coming decade as well as lasting health impacts due to smoking, policies suppressing unbalanced sex ratios could lead to welfare gains.
