Abstract
We address the impact of multinationals on host country market structure through reviewing existing empirical literature. Our main conclusion is that the majority of studies focus on samples of manufacturing industries/firms, neglecting the service sector, despite its importance. Future research should be directed to this sector and explore the possibility of bidirectional causality between foreign presence and host country industry concentration. Studies concerning the impact of multinationals on entry, exit and survival of host country firms must use more recent data, investigate the role of vertical linkages and taking into account other control variables that may affect the exit rate. Finally, future work should take into account the mode of foreign firm establishment in the host country.
