Contingent effects of quality signaling / Guodong (Gordon) Gao in Management science, Vol. 56 N° 6 (Juin 2010) 

Public ISBD [article]  in Management science > Vol. 56 N° 6 (Juin 2010) . - pp. 1012-1029 Titre : Contingent effects of quality signaling : Evidence from the indian offshore IT services industry Type de document : texte imprimé Auteurs : Guodong (Gordon) Gao, Auteur ; Anandasivam Gopal, Auteur ; Ritu Agarwal, Auteur Année de publication : 2010 Article en page(s) : pp. 1012-1029 Note générale : Management Langues : Anglais (eng) Mots-clés : Signaling  Certification  CMM  Outsourcing Index. décimale : 658 Organisation des entreprises. Techniques du commerce Résumé : We examine the heterogeneous returns to third-party quality signals in the context of the Indian software services industry. Prior theory has argued that quality certification is important in markets characterized by information asymmetry. However, there is limited understanding of the contingent factors that influence the efficacy of the quality signal. We focus on capability maturity model (CMM) certification, which is granted on the basis of a rigorous audit of software vendor's internal quality-oriented software construction practices, as a signal of unobservable quality. Drawing upon prior research in strategy and economics, we theorize that the impacts of CMM certification on a vendor's export performance are conditional on factors reflecting the vendor's strategy (diversification and location) and its competitive environment (the extent of CMM penetration in the vendor's competition). Analysis of panel data supports our predictions related to the contingent value of CMM certification, and shows that a software service provider gains more from certification in terms of its software exports when its service offerings are diversified, when it chooses to locate away from a cluster of other software service firms, and when the extent of CMM penetration in the competition is low. This study extends prior research in the information value of a quality signal on a firm's demand side that has, for the most part, focused solely on direct effects. We discuss the implications of our findings for the strategic trade-offs that managers of software service firms need to make.

Seller search and market outcomes in online auctions / Jason Kuruzovich in Management science, Vol. 56 N° 10 (Octobre 2010) 

Public ISBD [article]  in Management science > Vol. 56 N° 10 (Octobre 2010) . - pp. 1702-1717 Titre : Seller search and market outcomes in online auctions Type de document : texte imprimé Auteurs : Jason Kuruzovich, Auteur ; Siva Viswanathan, Auteur ; Ritu Agarwal, Auteur Année de publication : 2010 Article en page(s) : pp. 1702-1717 Note générale : Management Langues : Anglais (eng) Mots-clés : Seller  search  Online  auctions  Sequential  auctions  Online  channels Index. décimale : 658 Organisation des entreprises. Techniques du commerce Résumé : It has become widely accepted that information technology (IT) has had a profound influence on market transactions, with lower search costs for buyers often considered the key to lower prices and higher consumer welfare. However, sellers also use online channels to search for buyers whose product preferences and valuations match the sellers' offerings, and limited research has examined the impact of IT on sellers' search strategies or associated market outcomes. In this study, we investigate how market characteristics, the length of time the seller searches the auction marketplace for a buyer, and seller search in other websites influence the final sale price in online auctions. The online auction market for used vehicles provides a valuable opportunity to observe search processes of sellers, as the unique vehicle identification number associated with each vehicle enables the tracking of an individual item across both subsequent auctions and across other websites. We find that the market characteristics, duration of search, and search in other websites are each associated with a higher final sale price. Our findings highlight the importance of examining both buyer and seller search behaviors to further our understanding of the impacts of IT on market outcomes and efficiency.

Social contagion and information technology diffusion / Corey M. Angst in Management science, Vol. 56 N° 8 (Août 2010) 

Public ISBD [article]  in Management science > Vol. 56 N° 8 (Août 2010) . - pp. 1219-1241 Titre : Social contagion and information technology diffusion : The adoption of electronic medical records in U.S. hospitals Type de document : texte imprimé Auteurs : Corey M. Angst, Auteur ; Ritu Agarwal, Auteur ; V. Sambamurthy, Auteur Année de publication : 2010 Article en page(s) : pp. 1219-1241 Note générale : Management Langues : Anglais (eng) Mots-clés : Electronic  medical  record  Diffusion  Social  contagion  Propensity  Susceptibility  Infectiousness  Spatial  and  social  proximity Index. décimale : 658 Organisation des entreprises. Techniques du commerce Résumé : We use a social contagion lens to study the dynamic, temporal process of the diffusion of electronic medical records in the population of U.S. hospitals. Social contagion acknowledges the mutual influence among organizations within an institutional field and implicates information transmission through direct contact and observation as the mechanisms underlying influence transfer. We propose hypotheses predicting a hospital's likelihood of adopting electronic medical records as a function of its susceptibility to the influence of prior adopters, the infectiousness or potency of influence exerted by adopting hospitals, and its social and spatial proximity to prior adopters. Results obtained by fitting a heterogeneous diffusion model to data from a sample drawn from an annual survey, spanning 1975 to 2005, of almost 4,000 U.S. hospitals suggest that diffusion can be accelerated if specific attention is given to increasing social contagion effects. In particular, with respect to susceptibility to influence, greater hospital size and age are positively related to the likelihood of adoption for nonadopters, whereas younger hospitals are associated with greater infectiousness for adopters. A hospital's “celebrity” status also contributes to its infectiousness. We further find strong effects for social proximity and significant regional effects for spatial proximity and hospital size, suggesting that geographical covariates should be included in diffusion studies. Results also reinforce the importance of theorizing about and including interactions in examinations of social contagion.
