Abstract: Mergers and acquisitions (M&As) play a key role in the restructuring of the business sector, with potential implications for economic growth, allocative efficiency, market power and the public interest. This paper uses data from the Chambers of Commerce and Moody's Orbis, documents M&A deals in Italy and other major European Union countries to describe the firms involved and examine the effects of M&As on firm performance. The main findings show that, over the past decade, approximately 6,000 operations per year have been recorded in Italy, with the trend increasing over the last five years. M&As have primarily involved firms that are more technologically advanced, both in manufacturing and services, and have contributed to the consolidation of the production system. Within five years of the deal, employment in the consolidated firm is about 4 per cent lower than it would have been without the deal. This evidence is partly due to divestitures of business units, consistent with processes of productive reorganization. The impact of M&A transactions varies depending on the competitive environment: in less internationally exposed sectors, an increase in market power is also observed, whereas no significant effects are found in tradeable sectors.
