In this review we discuss the evidence for galaxy interactions and mergers in the distant universe and the role of mergers in forming galaxies. Observations show that the fraction of massive (M > M∗) galaxies involved in major mergers is roughly 5-10% at z ∼ 1. The merger fraction however increases steeply for the most massive galaxies up to z ∼ 3, where the merger fraction is 50±20%. Using N-b...

Despite the importance of post-merger IS integration to the success of the whole merger, post-merger IS integration literature remains scarce. This paper attempts to synthesise the often implicit or vague definitions of post-merger IS integration success with those provided in the vast body of literature on IS evaluation. As a result, four categories of success issues for post-merger IS integra...

Many corporate mergers fail to achieve their intended objectives. The literature indicates that slow post-merger integrations are partly responsible for such failure and highlights that a successful post-merger integration is essential to a successful merger. Recognizing the fact that information systems (IS) integration is important for effective merger performance and that few IS and merger r...

Merger Profitability and Trade Policy by Steffen Huck and Kai A. Konrad We study the profitability and welfare effects of merger in a strategic trade policy environment. Merger changes the strategic trade policy equilibrium. We show that merger can be profitable and welfare enhancing here, even though it is not profitable in a laissez-faire economy. A key element is the change in the government...

We study the complete merger of two massive stars inside a common envelope and the subsequent evolution of the merger product, a rapidly rotating massive supergiant. Three qualitatively different types of mergers have been identified and investigated in detail, and the post-merger evolution has been followed to the immediate presupernova stage. The “quiet merger” case does not lead to significa...

The impact of innovation on mergers has been a source of debate in merger enforcements. Innovative firms influence market structure by changing merger decisions, as mergers provide resources for commercialization of innovation and capturing knowledge spillovers. However, there is a limited empirical evidence on the innovation induced changes of merger likelihood. We construct panel data of merg...

An analysis of the social identity processes involved in organizational mergers suggests that organizational identification after a merger is contingent on a sense of continuity of identity. This sense of continuity, in turn, is argued to be contingent on the extent to which the individual's own pre-merger organization dominates, or is dominated by, the merger partner. In support of this analys...

Downstream Merger with Oligopolistic Input Suppliers by Kjell Erik Lommerud, Odd Rune Straume, Lars Sørgard We examine how a downstream merger affects input prices and, in turn, the profitability of such a merger under Cournot competition with differentiated products. Input suppliers can be interpreted as ordinary upstream firms, or trade unions organising workers. If the input suppliers are pl...
