Core Product Competence and Productivity Gains : The Role of Foreign Ownership

Recent theoretical contributions provide predictions about the effects of core product competence on firms' productivity. However, we know little about the influence of foreign ownership on core product competence that might also lead to productivity gains across firms. This paper uses firm-level data for 137 countries to investigate how foreign ownership affects firms' decision to become specialized at core products and the subsequently firm productivity gains. To tackle the possible endogeneity of foreign ownership, the instrumental variable approach and the propensity score matching technique are employed. The results show that foreign ownership has a positive and significant effect on firms' core product competence and this positive effect leads to productivity gains, especially for the most productive firms. We further reveal that foreign competition within an industry encourages firms to become specialized at core products, which could further lead to productivity gains across firms
