Abstract: This study investigates the effects of exports and overseas investments on the wage elasticity of labour demand for both foreign multinational corporations (MNCs) and Korean MNCs using a 2006–2015 firm-level unbalanced panel dataset from South Korea. I employ the system generalized method of moments to estimate a dynamic labour demand function to solve the problem of reverse causality due to potential endogeneity. The results suggest that exports play a critical role in increasing wage elasticity among foreign MNCs, whereas overseas investments render labour demand more elastic among both foreign MNCs and Korean MNCs. Particularly, these effects of globalization on increasing wage elasticity became strengthened among foreign MNCs during the post-financial crisis period. Moreover, the intra-firm and inter-firm exports of foreign MNCs from OECD nations, which reflect the vertical integration of foreign MNCs with their affiliated firms, increase the wage elasticity of labour demand. Since overseas investments induce higher wage elasticity of labour demand, overseas investment substitutes for local production activity. These empirical results imply that the rapid pace of globalization exacerbates the instability of the local labour market, and the aggravation of employment vulnerability during the post-crisis period is driven by foreign MNC activity.
