Originally coined as a term for a grouping of developing countries which that were neither mature market economies nor “Third World” and with earlier linked terminologies, emerging markets reflect an evolving and diverse literature with a series of opportunities, encompassing the purely theoretical through to the methodological and the analytical. This chapter provides an overview examination of such theoretical approaches, indicating where there might be similarities, differences, or advantages to deploying multiple approaches to better understand the complexity and diversity of human resource management in these contexts. Examples of research using these approaches are given. The theoretical approaches include institutional theory, cross-cultural perspectives, emerging market multinational companies internationalization perspectives, the Afro-Asian nexus, resource and social capital perspectives, the postcolonial approach, and an examination of hybrid models. The latter may include similarities, convergence, and the interplay between one or more of these approaches.
