Rival Reactions

چکیده
Mergers and acquisitions (M&As) are major events, reshaping competition among related firms (traditionally called rivals). Despite their seeming importance, most M&A studies have found only a limited empirical impact on rival stock prices. Our paper revisits this issue using a novel approach to characterize the degree of interactions among related firms based on their stock return correlations after controlling for market and industry price movements. Our approach filters out firms that are not related and distinguishes business partners from direct competitors. The results indicate that M&A announcements are on average bad news for both business partners and direct competitors of the acquirer. This provides significant evidence that M&As reinforce an acquirer’s competitive advantage, a validation of the competitive pressure hypothesis. JEL classification: G34

Testing Several Rival Models Using the Extension of Vuong\'s Test and Quasi Clustering
The two main goals in model selection are firstly introducing an approach to test homogeneity of several rival models and secondly selecting a set of reasonable models or estimating the best rival model to the true one. In this paper we extend Vuong's method for several models to cluster them. Based on the working paper of Katayama $(2008)$, we propose an approach to test whether rival models h...
متن کاملA Conjectural Variation Computable General Equilibrium Model with Free Entry
This paper proposes a procedure to incorporate the conjectural variation approach in Computable General Equilibrium (CGE) analysis such that the strategic interaction among rival firms in international markets can be modelled. It shows how to calibrate the conjectured reactions of rival domestic and foreign firms. It also shows that the approach suggested by Harrison, Rutherford and Tarr (hence...
متن کاملMarket Share Dynamics and the ‘Persistence of Leadership’ Debate
For how long does a typical 'market leader' in an industry maintain its position? This question has attracted continuing attention in the Industrial Organization literature over the past generation. Two rival views have emerged. The first, associated inter alia with Alfred Chandler (1990), asserts that leadership tends to persist for a 'long' time. The rival view, sometimes labelled 'Schumpeter...
متن کاملNew insights into small molecule activation by acyclic silylenes: a computational investigation.
Recently synthesized acyclic silylenes have the potential to rival transition metal complexes in performing single site small molecule activation, which is significant because of the need to find cheap and green alternatives to transition metal complexes for this important class of reactions. However, the current computational study, a full quantum chemical investigation with density functional...
متن کاملDistribution Design of Two Rival Decenteralized Supply Chains: a Two-person Nonzero Sum Game Theory Approach
We consider competition between two decentralized supply chains network under demand uncertainty. Each chain consists of one risk-averse manufacturer and a group of risk-averse retailers. These two chains present substitutable products to the geographical dispensed markets. The markets’ demands are contingent upon prices, service levels, and advertising efforts of two supply chains. We formulat...
