Techniques du commerce Résumé : Are the attitudes and beliefs of chief executive officers (CEOs) linked to their firms' innovative performance? This paper uses a measure of overconfidence, based on CEO stock-option exercise, to study the relationship between a CEO's “revealed beliefs” about future performance and standard measures of corporate innovation. We begin by developing a career concern model where CEOs innovate to provide evidence of their ability. The model predicts that overconfident CEOs, who underestimate the probability of failure, are more likely to pursue innovation, and that this effect is larger in more competitive industries. We test these predictions on a panel of large publicly traded firms for the years from 1980 to 1994. We find a robust positive association between overconfidence and citation-weighted patent counts in both cross-sectional and fixed-effect models. This effect is larger in more competitive industries. Our results suggest that overconfident CEOs are more likely to take their firms in a new technological direction.

Diversification, diseconomies of scope, and vertical contracting / Evan Rawley in Management science, Vol. 56 N° 9 (Septembre 2010)

Public ISBD [article]  in Management science > Vol. 56 N° 9 (Septembre 2010) . - pp. 1534-1550 Titre : Diversification, diseconomies of scope, and vertical contracting : Evidence from the taxicab industry Type de document : texte imprimé Auteurs : Evan Rawley, Auteur ; Timothy S. Simcoe, Auteur Année de publication : 2010 Article en page(s) : pp. 1534-1550 Note générale : Management Langues : Anglais (eng) Mots-clés : Diversification  Diseconomies  of  scope  Adaptation  Outsourcing  Asset  ownership Index. décimale : 658 Organisation des entreprises. Techniques du commerce Résumé : This paper studies how firms reorganize following diversification, proposing that firms use outsourcing, or vertical disintegration, to manage diseconomies of scope. We also consider the origins of scope diseconomies, showing how different underlying mechanisms generate contrasting predictions about the link between within-firm task heterogeneity and the incentive to outsource following diversification. We test these propositions using microdata on taxicab and limousine fleets from the Economic Census. The results show that taxicab firms outsource, by shifting the composition of their fleets toward owner-operator drivers, when they diversify into the limousine business. The magnitude of the shift toward driver ownership is larger in less urban markets, where the tasks performed by taxicab and limousine drivers are more similar. These findings suggest that (1) firms use outsourcing to manage diseconomies of scope at a particular point in the value chain and (2) interagent conflicts can be an important source of scope diseconomies.

Status, quality, and attention / Timothy S. Simcoe in Management science, Vol. 57 N° 2 (Février 2011) 

Public ISBD [article]  in Management science > Vol. 57 N° 2 (Février 2011) . - pp. 274-290 Titre : Status, quality, and attention : What's in a (Missing) name? Type de document : texte imprimé Auteurs : Timothy S. Simcoe, Auteur ; Dave M. Waguespack, Auteur Année de publication : 2011 Article en page(s) : pp. 274-290 Note générale : Management Langues : Anglais (eng) Mots-clés : Status  Technology  Sociology  of  science Index. décimale : 658 Organisation des entreprises. Techniques du commerce Résumé : How much are we influenced by an author's identity when evaluating his or her work? This paper exploits a natural experiment to measure the impact of status signals in the context of open standards development. For a period of time, e-mails announcing new submissions to the Internet Engineering Task Force would replace individual author names with "et al." if submission volumes were unusually high. We measure the impact of status signals by comparing the effect of obscuring high- versus low-status author names. Our results show that name-based signals can explain up to three-quarters of the difference in publication rates between high- and low-status authors. The signaling effect disappears for a set of prescreened proposals that receive more scrutiny than a typical submission, suggesting that status signals are more important when attention is scarce (or search costs high). We also show that submissions from high-status authors receive more attention on electronic discussion boards, which may help high-status authors to develop their ideas and bring them forward to publication.
