Abstract

Recent work in the supply chain literature suggests that the variance in orders placed with suppliers will be larger than that of sales to buyers. This distortion in demand information increases as it is passed along the supply chain from customers to upstream suppliers and has been referred to as “the bullwhip effect.” In this paper, we argue that the bullwhip effect reduces the ability of order backlog to predict future sales and earnings for upstream suppliers. Results obtained from our empirical analysis support this proposition. We find that the impact of bullwhip on the predictive ability of order backlog is further accentuated in firms with longer operating cycles. Market intermediaries such as financial analysts, on average, are unable to fully account for differences in the predictive ability of order backlog. However, analysts belonging to employers that follow all firms in a vertical supply chain do a better job of understanding the impact of bullwhip on the predictive ability of order backlog. In additional tests, we find that the bullwhip effect also impedes the ability of inventory components to predict future sales and earnings. Les travaux de recherche récents sur la chaîne d'approvisionnement semblent indiquer que la fluctuation des commandes passées auprès des fournisseurs est plus importante que celle des ventes réalisées auprès des acheteurs. Cette distorsion dans l'information relative à la demande, que l'on appelle « effet coup de fouet », augmente à mesure qu'elle remonte la chaîne d'approvisionnement, des clients jusqu'aux fournisseurs en amont. Selon les auteurs, l'effet coup de fouet réduit la mesure dans laquelle le carnet de commandes permet de prédire les ventes et les bénéfices futurs pour les fournisseurs en amont, une proposition que viennent appuyer les résultats tirés de leur analyse empirique. Les auteurs constatent que l'incidence de l'effet coup de fouet sur les propriétés prédictives du carnet de commandes est plus marqué dans les sociétés dont les cycles d'exploitation sont plus longs. En moyenne, les intermédiaires du marché comme les analystes financiers sont incapables de tenir parfaitement compte des variations dans les propriétés prédictives du carnet de commandes. Toutefois, les analystes travaillant pour des employeurs qui suivent toutes les sociétés d'une chaîne d'approvisionnement verticale comprennent mieux l'incidence du coup de fouet sur les propriétés prédictives du carnet de commandes. En procédant à des tests supplémentaires, les auteurs constatent que l'effet coup de fouet affecte également les propriétés prédictives des articles de stock en ce qui a trait aux ventes et aux bénéfices futurs.
