Lock-in situations in supply chains / Ram Narasimhan in Journal of operations management, Vol. 27 N° 5 (Octobre 2009) 

Public ISBD [article]  in Journal of operations management > Vol. 27 N° 5 (Octobre 2009) . - pp. 374–389 Titre : Lock-in situations in supply chains : A social exchange theoretic study of sourcing arrangements in buyer–supplier relationships Type de document : texte imprimé Auteurs : Ram Narasimhan, Auteur ; Anand Nair, Auteur ; David A. Griffith, Auteur Année de publication : 2010 Article en page(s) : pp. 374–389 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Supply  chain  management  Social  exchange  theory  Economic  modeling  Behavioral  experiment  Power  Dependence  Justice Résumé : Social exchange theory is used to gain a better understanding of the relationship between a buyer and a supplier that is characterized by lock-in situations. We begin by reviewing the theoretical foundations of social exchange theory. Next, we use an illustrative multinational business example from a Danish Business Group to demonstrate the complexities of the lock-in situation. Conjectures related to lock-in behaviors are initially developed and then examined by means of a game-theoretic model. The analysis provides a basis for the development of propositions which are examined employing a behavioral experiment. The results indicate that the optimal pricing strategy of the supplier is to lower the price with increasing demand and the optimal investment intensity of the buyer decreases with increasing demand. The paper concludes by presenting directions for future research.

Perspectives on risk management in supply chains / Ram Narasimhan in Journal of operations management, Vol. 27 N° 2 (Avril 2009) 

Public ISBD [article]  in Journal of operations management > Vol. 27 N° 2 (Avril 2009) . - pp. 114–118 Titre : Perspectives on risk management in supply chains Type de document : texte imprimé Auteurs : Ram Narasimhan, Auteur ; Srinivas Talluri, Auteur Année de publication : 2009 Article en page(s) : pp. 114–118 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Risk  management  Supply  chains  Risk  mitigation Résumé : Managing risk in supply chains is an important topic in supply chain management. The topic's importance is due to several industry trends currently in place: increase in strategic outsourcing by firms, globalizations of markets, increasing reliance on suppliers for specialized capabilities and innovation, reliance on supply networks for competitive advantage, and emergence of information technologies that make it possible to control and coordinate extended supply chains. This article identifies some important aspects of risk management in supply chains and summarizes the four articles that are in this special issue. This emerging area of research interest deserves considerable attention and it is our hope that the articles in this special issue would spur additional research on this important topic.

Strategic interdependence, governance effectiveness and supplier performance / Santosh K. Mahapatra in Journal of operations management, Vol. 28 N° 6 (Novembre 2010) 

Public ISBD [article]  in Journal of operations management > Vol. 28 N° 6 (Novembre 2010) . - pp. 537–552 Titre : Strategic interdependence, governance effectiveness and supplier performance : A dyadic case study investigation and theory development Type de document : texte imprimé Auteurs : Santosh K. Mahapatra, Auteur ; Ram Narasimhan, Auteur ; Paolo Barbieri, Auteur Année de publication : 2011 Article en page(s) : pp. 537–552 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Business  context  Complexity  Life  cycle  Strategic  interdependence  Governance  structure  Exchange  practices  Supplier  performance Résumé : Inter-organizational exchange governance approaches are often characterized as two broad types: relational and transactional. However, in fast changing business contexts, the contextual contingencies do not present ideal conditions for practicing purely relational or transactional approach. Understanding the dynamic of key contextual factors and their effects on a firm's resource capabilities and inter-organizational power structure is crucial for identifying the appropriate governance structure over time. In this paper we explore the exchanges between an OEM and five of its strategic suppliers that operate in high-end, short product life cycle motorbike industry, to understand the key contextual factors and the relationships among business context, governance structure, and exchange practices in a dyadic context. It is observed that firms deviate from the conventional choices of either transactional or relational governance to a combination of contractual and relational aspects to make the governance structure effective. Based on case studies, a theoretical framework is proposed to explain the rationale, feasibility and effectiveness of combining contractual and relational aspects in different contexts. The framework suggests that the degree of strategic interdependence between the trading partners fundamentally drives the effectiveness of governance structure and exchange practices.
