Bargaining chains / William S. Lovejoy in Management science, Vol. 56 N° 12 (Décembre 2010) 

Public ISBD [article]  in Management science > Vol. 56 N° 12 (Décembre 2010) . - pp. 2282-2301 Titre : Bargaining chains Type de document : texte imprimé Auteurs : William S.

Techniques du commerce Résumé : We consider a firm that designs a new product and wishes to bring it to market but does not have ownership or control over all of the resources required to make that happen. The firm must select and contract with one of several possible tier 1 suppliers for necessary inputs, who do the same with their (tier 2) suppliers, etc. This general situation is common in industry. We assume tier-wise negotiations, sole sourcing within each tier, complete local information, and horizontal competition. We develop a bargaining-based solution to the negotiations between two adjacent multifirm tiers and show its consistency with familiar solution concepts from the theories of bargaining and cooperative games. We then link up multiple bargaining modules to generate chainwide predictions for efficiency and profitability in supply chains with an arbitrary number of tiers and an arbitrary number of firms per tier. We investigate the implications of the results for investments in process improvements or supplier development.

Efficient structures for innovative social networks / William S. Lovejoy in Management science, Vol. 56 N° 7 (Juillet 2010) 

Public ISBD [article]  in Management science > Vol. 56 N° 7 (Juillet 2010) . - pp. 1127-1145 Titre : Efficient structures for innovative social networks Type de document : texte imprimé Auteurs : William S. Lovejoy, Auteur ; Amitabh Sinha, Auteur Année de publication : 2010 Article en page(s) : pp. 1127-1145 Note générale : Management Langues : Anglais (eng) Mots-clés : Innovation  Ideation  Social  networks Index. décimale : 658 Organisation des entreprises. Techniques du commerce Résumé : What lines of communication among members of an organization are most productive in the early, ideation phase of innovation? We investigate this question with a recombination and selection model of knowledge transfer operating through a social network. We find that ideation is accelerated when people in the organization dynamically churn through a large (ideally the entire population) set of conversational partners over time, which naturally begets short path lengths and eliminates information bottlenecks. Group meetings, in which the content of conversations is available to all for consideration, are another way to learn in parallel and accelerate the ideation process, although for complex problems they may not offer significant advantages over the best decentralized networks. The idealized core-periphery graphs emerge as an important family on the time–cost efficient frontier. New sociometrics for the analyses of innovation processes emerge from this investigation.
