Abstract Through the lens of a quantitative general equilibrium model of international trade and multinational production, this paper studies corporate tax competition and cooperation among asymmetric countries. The model theoretically supports the empirical regularities that corporate income taxation influences multinational firms' location and production decisions. Calibrating the model to three asymmetric countries for a hypothetical tax competition, I find that race to the bottom occurs in t

Abstract We explore the wage effects of offshoring‐induced employment shocks in US commuting zones (CZs) and industries. Using data on petitions for the Trade Adjustment Assistance (TAA), we measure such shocks by computing the share of TAA‐certified offshoring‐induced layoffs out of total employment. We further identify material‐offshoring shocks and service‐offshoring shocks and connect the TAA data to individual‐level worker data from the American Community Survey. Empirical results show stat

ABSTRACT Using commodity‐level input–output tables with detailed import matrices for South Korea, we construct a direct industry‐level measure of offshoring, avoiding the proportionality assumption common in prior studies. Comparing measures with and without this assumption, we reveal significant disparities, particularly in service offshoring. Integrating this measure with individual‐level worker data, we estimate the wage effects of material and service offshoring between 2005 and 2014. Both i
