Abstract

This paper analyzes the impacts of importing intermediate digital inputs (IDIs) on income inequality between high-skilled and low-skilled workers, using a novel dataset that merges recent EU KLEMS and OECD data for 29 countries and 15 industries for 2008-2020. We find that IDI imports significantly widen income inequality, because such imports are associated with higher technology and capital intensities, which directly increase income inequality by complementing high-skilled labor while substituting for low-skilled labor, and indirectly exacerbate inequality through workforce skill upgrading. Heterogeneity analysis shows that these occur primarily in highly digitalized countries and industries, as well as technology-intensive sectors. We also construct two shift-share instrumental variables, namely the global imported IDI shocks and the global digital export shocks, to address endogeneity.
