Firms operate under a wide range of rules and regulations. These include, for example, environmental regulations (in which some industries have increased regulatory exposure) and finance and accounting (where all industries have reporting requirements). In other areas, such as antitrust cartels,...

Antitrust regulators around the world, including in the UK, have proposed changes to merger review policies that impact how acquisitions of start-ups would be investigated and evaluated. Such changes will likely lead to heightened scrutiny—and increased costs and longer reviews—for many...

A growing number of policymakers and scholars are calling for tougher rules to curb corporate acquisitions. But these appeals are premature. There is currently little evidence to suggest that mergers systematically harm consumer welfare. More importantly, scholars fail to identify alternative...

An intense academic debate has arisen recently concerning the crucial bedrock that underpins a corporate governance regime where widely-held public companies dominate. In the discourse, little has been said about the contribution of merger activity. The paper seeks to address this gap by...

A great merger wave occurring in the United States between 1897 and 1903 was the single most important event in a process that yielded the pattern of managerial control and dispersed share ownership which currently distinguishes America's corporate economy from arrangements in most other...

This paper presents a broad retrospective evaluation of mergers and merger decisions in the digital sector. We first discuss the most crucial features of digital markets such as network effects, multi-sidedness, big data, and rapid innovation that create important challenges for competition...

Over the period 2015-2017, the five giant technologically leading firms, Google, Amazon, Facebook, Amazon and Microsoft (GAFAM) acquired 175 companies, from small start-ups to billion dollar deals. By investigating this intense M&A, this paper ambitions a better understanding of the Big Five's...

We find that stricter merger control legislation increases abnormal announcement returns of targets in bank mergers by 7 percentage points. Analyzing potential explanations for this result, we document an increase in the pre-merger profitability of targets, a decrease in the size of acquirers...

Advanced economic instruments like simulation models are enjoying an increased popularity in practical antitrust. There is hope that they being quantitative predictive economic evidence can substitute for qualitative structural analysis and lead to unambiguous results. This paper demonstrates...

Advances in competition economics as well as in computational and empirical methods have offered the scope for the employment of merger simulation models in merger control procedures during the past almost 15 years. Merger simulation is, nevertheless, still a very young and innovative instrument...
