Trade Openness and Vertical Structure: Evidence From Korean Firm-Level Data

Recent theories and empirics suggest that trade openness increases production fragmentation across countries. In this paper, we focus on the relationship between trade openness and firms’ choice of vertical structure. We find supportive, firm-level evidence that upon trade liberalization, firms restructure their organization by downsizing their domestic production processes (i.e. domestic vertical disintegration) and relocating their input production plants to other countries (i.e. cross-border vertical integration).
