This review examines how M how innovation shapes who buys whom; and how acquisition markets affect inventive effort, start-up exits, and the build-versus-buy boundary. Post-M&A outcomes are heterogeneous because deals are selected matches and innovation has multiple margins: R&D effort, patenting, novelty, exploration, exploitation, commercialization, diffusion, and human capital reallocation. The review closes by linking property rights and labor market perspectives on inventors, teams, mobility, acqui-hiring, and labor market power and by outlining a policy-relevant agenda.
