Although numerous studies analyze mergers and acquisitions (M&As) in and out of developed economies (DE), a much smaller number of studies focus on M&As in and out of emerging economies (EE). Since there are significant differences in institutional environments, corporate governance practices, and markets between DE and EE, existing knowledge on acquisitions can be extended by examining M&As in and out of EE. This paper addresses this gap and identifies the main findings of studies on acquisitions in and out of EE. The review deals with EE M&A antecedents and performance outcomes, with a focus on what new insights can be gained and what new research directions are revealed. This paper also develops propositions regarding EE M&A antecedents and performance.
