#The volume provides provocative new insights into the dynamic relationship between two of the most strategic priorities for 21st century firms: technological innovation and M&As. It does so by bringing together in a novel way the literature on these two different areas of firm activity and by adding economic theory and advanced empirical methods (both qualitative and quantitative) to the management literature on the subject. The analysis proves remarkably fruitful, finally creating less uncertainty and inconclusiveness around the empirics of post M&A performance. By developing a broad set of measures on innovation for assessing the impact of M&A on innovation, and by relying on fascinating case studies on individual M&As (rather than just using R&D expenditures, patent counts, etc.), the authors are able to document the importance for post M&A performance of dynamic factors like market and technology relatedness (between partners) # findings that have critical implications for economic theorists, business practitioners and policymakers.#
