Rival Reactions
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 ...
متن کامل"Beat-Your-Rival" Routing Games
In the traditional setting of routing games, the standard assumption is that selfish agents are unconcerned with the performance of their competitors in the network. We propose an extension to this setting by modeling agents to consider a combination of their own performance as well as that of their rivals. Per agent, we parameterize this trade-off, thereby allowing agents to be partially selfi...
متن کاملStrategic Seeding of Rival Opinions
We present a network influence game that models players strategically seeding the opinions of nodes embedded in a social network. A social learning dynamic, whereby nodes repeatedly update their opinions to resemble those of their neighbors, spreads the seeded opinions through the network. After a fixed period of time, the dynamic halts and each player’s utility is determined by the relative st...
متن کاملRival ideas about binocular rivalry
Binocular rivalry has been used to investigate neural correlates of visual awareness. For this investigation to succeed, however, it is necessary to know what rivals during binocular rivalry. Recent work has raised questions about whether rivalry is between eyes or between stimuli. We find that stimulus rivalry occurs only within a limited range of spatial and temporal parameters--otherwise eye...
متن کاملMALDI mass spectrometry imaging of proteins exceeding 30,000 daltons.
BACKGROUND Since its introduction 10 years ago by Caprioli and associates, MALDI mass spectrometry imaging has enabled spatial analysis of drugs, lipids, peptides, and polypeptides. In polypeptides, the detectable mass range is limited to small proteins with a mass less than 25 kDa. This is a limitation, as many proteins, including cytokines, growth factors, enzymes, and receptors have molecula...
