Techniques du commerce Résumé : In our prior work on product diffusions in presence of a capacity constraint, we postulated that a firm operating in such an environment should always attempt to fulfill as much of the present demand as is possible with the capacity constraint. In other words, the firm would never have demand backlogged while accumulating inventory. In this note, we derive a sufficient condition for the optimality of such fulfillment policy.

Reference dependence in multilocation newsvendor models / Teck-Hua Ho in Management science, Vol. 56 N° 11 (Novembre 2010) 

Public ISBD [article]  in Management science > Vol. 56 N° 11 (Novembre 2010) . - pp. 1891-1910 Titre : Reference dependence in multilocation newsvendor models : A structural analysis Type de document : texte imprimé Auteurs : Teck-Hua Ho, Auteur ; Noah Lim, Auteur ; Tony Haitao Cui, Auteur Année de publication : 2011 Article en page(s) : pp. 1891-1910 Note générale : Management Langues : Anglais (eng) Mots-clés : Multilocation  inventory  system  Newsvendor  Behavioral  operations  management  Experimental  economics Index. décimale : 658 Organisation des entreprises. Techniques du commerce Résumé : We propose a behavioral theory to predict actual ordering behavior in multilocation inventory systems. The theory rests on a well-known stylized fact of human behavior: people's preferences are reference dependent. We incorporate reference dependence into the newsvendor framework by assuming that there are psychological costs of leftovers and stockouts. We also hypothesize that the psychological aversion to leftovers is greater than the disutility for stockouts. We then experimentally test the proposed theory in both the centralized and decentralized inventory structures using subjects motivated by substantial financial incentives. Consistent with the proposed theory, actual orders exhibit the so-called "pull-to-center" bias and the degree of bias is greater in the high-profit margin than in the low-profit margin condition. These systematic biases are shown to eliminate the risk-pooling benefit when the demands across store locations are strongly correlated. Because the proposed model nests the standard inventory and ex post inventory error minimization theories as special cases, one can systematically evaluate the predictive power of each alternative using the generalized likelihood principle. We structurally estimate all three theories using the experimental data, and the estimation results strongly suggest that the proposed behavioral theory captures actual orders and profits better. We also conduct two experiments to validate the behavioral model by manipulating the relative salience of the psychological costs of leftovers versus that of stockouts to alleviate the pull-to-center bias.
