摘要：Companies such as Zara and World Co. have recently implemented novel product development processes and supply chain architectures enabling them to make more product design and assortment decisions during the selling season, when actual demand information becomes available. How should such retail firms modify their product assortment over time in order to maximize overall profits for a given selling season? Focusing on a stylized version of this problem, we study a finite horizon multiarmed ban...

摘要：Modularity in product design and flexible supply chains is increasingly common in buyer-supplier relationships. Although the benefits of supply chain flexibility and component modularity for end-product manufacturers are accepted, little is known about their impact on suppliers. We advance the literature on modularity by exploring how three aspects of a supplier's relationships with its customers affect the supplier's survival: duration of buyer-supplier relationships, autonomy from customers,...

摘要：This research examines the evolution of cooperative interorganizational relationships and provides an empirical test of four propositions from the DSO (Dwyer et al. 1987) hfe-cycle theory, and one proposition from the RV (Ring and Van cle Ven 1994) theory of relationship development. Using primary data from over 1,500 resellers in a channel of distribution, we find that the mature phase is not the pinnacle of the relationship lifecycle; relationship properties (e.g., relationship harmony, over...

摘要：We consider a finite-state, finite-action, infinite-horizon, discounted reward Markov decision process and study the bias and variance in the value function estimates that result from empirical estimates of the model parameters. We provide closed-form approximations for the bias and variance, which can then be used to derive confidence intervals around the value function estimates. We illustrate and validate our findings using a large database describing the transaction and mailing histories f...

摘要：We develop a model of consumer learning and choice behavior in response to uncertain service in the marketplace. Learning could be asymmetric, that is, consumers may associate different weights with positive and negative experiences. Under this consumer model, we characterize the steady-state distribution of demand for retailers given that each retailer holds a constant in-stock service level. We then consider a noncooperative game in steady state between two retailers competing on the basis o...

摘要：In this paper, we study the impact of coordinated replenishment and shipment in inventory/distribution systems. We analyze a system with multiple retailers and one outside supplier. Random demand occurs at each retailer, and the supplier replenishes all the retailers. In traditional inventory models, each retailer orders directly from the supplier whenever the need arises. We present a new, centralized ordering policy that orders for all retailers simultaneously. The new policy is equivalent t...

摘要：Empirical evidence suggests that decision makers often weight successive additional units of a valued attribute or monetary endowment unequally, so that their utility functions are intrinsically nonlinear or irregularly shaped. Although the analyst may impose various functional specifications exogenously, this approach is ad hoc, tedious, and reliant on various metrics to decide which specification is best. In this paper, we develop a method that yields individual-level, flexibly shaped utilit...

摘要：This paper presents new evidence regarding a firm's probability for survival, based on the network structure of the firm's managers. We found that start-ups that have larger informal communication networks increased their chance to survive external shock. Original data have been collected from Israeli software start-ups during the dot-com economic growth. About eight years later, we added information about their ability to survive the burst of the dot-com. bubble. From a theoretical point of v...

摘要：The declining cost of information technology (IT) over time provides the later entrant in information-intensive industries a cost advantage. On the other hand, the earlier entrant has the potential to build and retain its market share if consumers incur a cost in switching to the later entrant. We investigate the impact of a decline in the IT cost and the switching cost on IT investment strategies of firms. We find that a declining IT cost always hurts the early entrant's profit. The early ent...
