This paper examines how information on the purchasing patterns of different customer segments can be used to more accurately evaluate the economic impact of mergers. Using a detailed dataset for the leading manufacturers in the US during the late nineties, I evaluate the welfare effects of the...

How far should an industry be allowed to consolidate when competition and innovation are endogenous? We develop a stochastically alternating-move game of dynamic oligopoly, and estimate it using data from the hard disk drive industry, in which a dozen global players consolidated into only three...

In response to global market forces such as deregulation and globalization, technological change and digital convergence, the telecommunications in the 1990s witnessed an enormous worldwide round of Mergers & Acquisitions (M&A). Given both M&A and Innovation a major means of today's competitive...

The telecommunications in the 1990s witnessed an enormous worldwide round of Mergers & Acquisitions (M&A). This paper examines the innovation determinants of M&A activity and the consequences of M&A transactions on the technological potential and the innovation performance. We examine the...

Migration of large IT projects becomes complex, especially where a large number of software assets are involved. IT migration is essential to integrate legacy systems with new systems, and when large firms are acquired by another firm. A structured methodology is needed for seamless integration....

Merger control authorities may approve a merger based on a so-called “efficiency defence”. An important aspect in clearing mergers is that the efficiencies need to be merger-specific. Joint ventures, and in particular research joint ventures (RJVs), may achieve comparable efficiencies...

Merged firms are typically rather complex organizations. Accordingly, me rger has a more profound effect on the structure of a market than simply reducing the number of competitors. We show that this may render horizontal mergers profitable and welfare – improving even if costs are linear. The...

We present a model of takeover where the target optimally sets its reserve price. Under relatively standard symmetry restrictions, we obtain a unique equilibrium. The probability of takeover is only a function of the number of firms and of the insiders' share of total industry gains due to the...

The seminal paper by Salant, Switzer and Reynolds (1983) showed that merger in a standard Cournot framework with linear demand and linear costs is not profitable unless a large majority of the firms are involved in the merger. However, many strategic aspects matter for firm competition such as...
