When players change teams, they fight harder against their former employer

But they compete less against ex-colleagues. Thorsten Grohsjean discusses what this means for companies

The Strength of Direct Ties: Evidence from the Electronic Game Industry

We analyze the economic effects of a developer’s connectedness in the electronic game industry. Knowledge spillovers between developers should be of special relevance in this knowledge-based industry. We calculate measures for a developer’s connectedness to other developers at multiple points in time. In a regression with developer, developing firm, publishing firm, and time fixed effects, we find that the number of a developer’s direct ties, i.e., common past experience, has a strong effect on both a game’s revenues and critics’ scores. The intensity of indirect ties makes no additional contribution to the game’s success

Performance Feedback, Firm Resources, and Strategic Change

Combining insights from the behavioral theory of the firm and the resource-based view we investigate the antecedents of strategic change in fast-changing environments. We hypothesize the independent and joint effects of performance feedback and of flexible and specific resources on strategic change. Using an unbalanced panel of 493 publisher-year observations we find that negative performance feedback triggers more strategic change. Further, while flexible resources have no direct influence on strategic change they weaken the negative relationship between performance feedback and strategic change. Finally, we find that larger stocks of specific resources lead to less strategic change.Performance feedback; strategic change; resource-based-view; video game industry

Collaborations that hurt firm performance but help employees' careers

When a firm and a competitor collaborate with the same partner, they compete for the shared partner's resources and attention. Such“peer competition”has been shown to negatively affect a firm's access to resources and its performance.One might expect that also the employees’ careers to suffer as a result. However, we argue that the firm's employees benefit from such collaborations. They lever-age these collaborations to build social capital—helping their mobility and careers. We find empirical support for our theory using a large sample data set of video game companies. Our study points to an important yet hitherto neglected agency conflict: employees seek interfirm collaborations that benefit them person-ally but hurt their firm

The new needs friends: Simmelian strangers and the selection of novelty

The paradox of rejecting novel ideas while being motivated to select them exists in many realms. Deviating from prior research that investigated several internal levers to promote the funding of novel ideas in the sciences, we focus on an external lever by investigating how seconded employees increase the selection of novel ideas in two ways: (1) they select more novel ideas themselves, and (2) they influence permanent employees to do the same. Combining unique quantitative longitudinal data and 37 in-depth interviews, we test our predictions in the secondment program at the National Science Foundation and find broad support for our theoretical arguments. Our findings have implications for scholars of science and innovation by proposing a relatively light-touch intervention to facilitate the selection of novel ideas

Evaluating novelty:the role of panels in the selection of R&D projects

Building on a unique, multi-source, and multi-method study of R&D projects in a leading professional services firm, we develop the argument that organizations are more likely to fund projects with intermediate levels of novelty. That is, some project novelty increases the share of requested funds received, but too much novelty is difficult to appreciate and is selected against. While prior research has considered the characteristics of the individuals generating project ideas, we shift the focus to the panel of selectors and explore how they shape the evaluation of novelty. We theorize that a high panel workload reduces panel preference for novelty in selection, whereas a diversity of panel expertise and a shared location between panel and applicant increase preference for novelty. We explore the implications of these findings for theories of innovation search, organizational selection, and managerial practice

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

An embedding technique to determine ττ backgrounds in proton-proton collision data

An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe
