Buying from the babbling retailer? / Gad Allon in Management science, Vol. 57 N° 4 (Avril 2011) 

Public ISBD [article]  in Management science > Vol. 57 N° 4 (Avril 2011) . - pp. 713-726 Titre : Buying from the babbling retailer? : The impact of availability information on customer behavior Type de document : texte imprimé Auteurs : Gad Allon, Auteur ; Achal Bassamboo, Auteur Année de publication : 2011 Article en page(s) : pp. 713-726 Note générale : Management Langues : Anglais (eng) Mots-clés : Inventory  Cheap  talk  Revenue  management Index. décimale : 658 Organisation des entreprises. Techniques du commerce Résumé : Provision of real-time information by a firm to its customers has become prevalent in recent years in both the service and retail sectors. In this paper, we study a retail operations model where customers are strategic in both their actions and in the way they interpret information, whereas the retailer is strategic in the way it provides information. This paper focuses on the ability (or the lack thereof) to communicate unverifiable information and influence customers' actions. We develop a game-theoretic framework to study this type of communication and discuss the equilibrium language emerging between the retailer and its customers. We show that for a single retailer and homogeneous customer population setting, the equilibrium language that emerges carries no information. In this sense, a single retailer providing information on its own cannot create any credibility with the customers. We study how the results are impacted due to the heterogeneity of the customers. We provide conditions under which the firm may be able to influence the customer behavior. In particular, we show that the customers' willingness to pay and willingness to wait cannot be ranked in an opposite manner. However, even when the firm can influence each customer class separately, the effective demand is not impacted.

Cutting in line / Gad Allon in Management science, Vol. 58 N° 3 (Mars 2012) 

Public ISBD [article]  in Management science > Vol. 58 N° 3 (Mars 2012) . - pp. 493-506 Titre : Cutting in line : Social norms in queues Type de document : texte imprimé Auteurs : Gad Allon, Auteur ; Eran Hanany, Auteur Année de publication : 2012 Article en page(s) : pp. 493-506 Note générale : Management Langues : Anglais (eng) Mots-clés : Queues  Games  Group  decisions  Social  norms Résumé : Although the norm in many retail banks is to serve customers on a first-come, first-served basis, some customers try to cut the line, usually by providing an excuse for their urgency. In other queues, however, this behavior is considered unacceptable and is aggressively banned. In all of these cases, customer exhibit strategies that have not yet been explored in the operations literature: they choose whether or not to cut the line and must also decide whether to accept or reject such intrusions by others. This paper derives conditions for the emergence of such behavior in equilibrium among the customers themselves, i.e., when the queue manager is not involved in granting priorities and the customers have to use community enforcement to sustain such equilibria.

Global dual sourcing / Gad Allon in Management science, Vol. 56 N° 1 (Janvier 2010) 

Public ISBD [article]  in Management science > Vol. 56 N° 1 (Janvier 2010) . - pp. 110-124 Titre : Global dual sourcing : Tailored base-surge allocation to near- and offshore production Type de document : texte imprimé Auteurs : Gad Allon, Auteur ; Jan A. Van Mieghem, Auteur Année de publication : 2010 Article en page(s) : pp. 110-124 Note générale : Management Langues : Anglais (eng) Mots-clés : Inventory  production  Stochastic  models  Applications  Probability  Stochastic  model  applications Index. décimale : 658 Organisation des entreprises. Techniques du commerce Résumé : When designing a sourcing strategy in practice, a key task is to determine the average order rates placed to each source because that affects cost and supplier management. We consider a firm that has access to a responsive nearshore source (e.g., Mexico) and a low-cost offshore source (e.g., China). The firm must determine an inventory sourcing policy to satisfy random demand over time. Unfortunately, the optimal policy is too complex to allow a direct answer to our key question. Therefore, we analyze a tailored base-surge (TBS) sourcing policy that is simple, used in practice, and captures the classic trade-off between cost and responsiveness. The TBS policy combines push and pull controls by replenishing at a constant rate from the offshore source and producing at the nearshore plant only when inventory is below a target. The constant base allocation allows the offshore facility to focus on cost efficiency, whereas the nearshore facility's quick response capability is utilized only dynamically to guarantee high service. The research goals are to (i) determine the allocation of random demand into base and surge capacity, (ii) estimate corresponding working capital requirements, and (iii) identify and value the key drivers of dual sourcing. We present performance bounds on the optimal cost and prove that economic optimization brings the system into heavy traffic. We analyze the sourcing policy that is asymptotically optimal for high-volume systems and present a simple “square-root” formula that is insightful to answer our questions and sufficiently accurate for practice, as is demonstrated with a validation study.

Large-scale service marketplaces / Gad Allon in Management science, Vol. 58 N° 10 (Octobre 2012) 

Public ISBD [article]  in Management science > Vol. 58 N° 10 (Octobre 2012) . - pp. 1854-1872 Titre : Large-scale service marketplaces : The role of the moderating firm Type de document : texte imprimé Auteurs : Gad Allon, Auteur ; Achal Bassamboo, Auteur ; Eren B. Çil, Auteur Année de publication : 2012 Article en page(s) : pp. 1854-1872 Note générale : Management Langues : Anglais (eng) Mots-clés : Service  operations  Fluid  models  Asymptotic  analysis  Large  games  Noncooperative  game  theory Résumé : Recently, large-scale, Web-based service marketplaces, where many small service providers compete among themselves in catering to customers with diverse needs, have emerged. Customers who frequent these marketplaces seek quick resolutions and thus are usually willing to trade prices with waiting times. The main goal of this paper is to discuss the role of the moderating firm in facilitating information gathering, operational efficiency, and communication among agents in service marketplaces. Surprisingly, we show that operational efficiency may be detrimental to the overall efficiency of the marketplace. Furthermore, we establish that to reap the “expected” gains of operational efficiency, the moderating firm may need to complement the operational efficiency by enabling communication among its agents. The study emphasizes the scale of such marketplaces and the impact it has on the outcomes.
