Spillovers from foreign direct investment: Within or between industries?

This paper contributes an estimation framework to measure both technological and linkage externalities from foreign direct investment (FDI). Empirical research dealt mainly with intra-industry spillovers from FDI with restrictive treatment of inter-industry effects until recently. However, as optimal organization of the multinational corporation (MNC) involves minimization of profit losses due to leakage of technical information to competitors, host-country firms within the MNC's sector experience limited productivity gains ensuing FDI. Host-country producers in other sectors may benefit. For example, MNCs transfer knowledge to local downstream clients, or outsource to local upstream suppliers. Hence, FDI substitutes within-sector domestic investment but complements it across sectors. The net impact on aggregate capital formation by host-country producers hinges on the interaction between linkages and spillovers. Estimations based on the Colombian Manufacturing Census yield the sectoral pattern of FDI spillovers displaying knowledge propagation between but not within industries. The findings reveal outsourcing relationships of MNCs with local upstream suppliers as the channel of diffusion.
