European Journal of International Management, Vol. ahead-of-print, No. ahead-of-print. Abstract: This study aims to map what we know and what we do not know concerning both the institutional theory and OFDI in order to elucidate how this subject has been treated in the international business arena and how it could help us to understand not only the emerging markets phenomena, but also how institutions and OFDI can open new research venues to the understanding of IB. To do so, we reviewed 140 papers concerning the relationship between institutions and OFDI. By applying both keyword co-occurrence and content analysis, our review showed that the main researches are distributed into five sub-fields: government support, location choice, market strategy, political institutions, and specific advantages. This article not only maps studies, but also shows underexplored research streams and how each one impacts the IB studies. Additionally, our study can help develop future studies by pointing out research gaps.
