This study examines the health effect of input tariff reductions on Chinese manufacturing workers and its heterogeneity across skill levels. We first provide a simple model to demonstrate the mechanisms. We then put the predictions of the model into a test using the China Health and Nutrition Survey data. Exploiting prefecture variations in input tariff shocks, we find that input tariff reductions following China's WTO accession adversely affect worker health through increased working hours. Moreover, input tariff reductions widen both the income and the health gaps between skilled and unskilled workers. Further welfare analysis indicates that ignoring health outcomes would substantially underestimate the welfare disparity between skilled and unskilled workers.
