摘要：We model an environment where e-retailers sell similar products and endogenously engage in both brand advertising (to create loyal customers) and price advertising (to attract shoppers). In contrast to models where loyalty is exogenous, endogenizing the creation of loyal customers by allowing firms to engage in brand advertising leads to a continuum of symmetric equilibria; however, there is a unique equilibrium in secure strategies, and the set of equilibria converges to this unique equilibri...

摘要：Prior research provides only weak and controversial evidence that people overestimate the likelihood of desirable events (wishful thinking), but strong evidence that people bet more heavily on those events (wishful betting). Two experiments show that wishful betting contaminates beliefs in laboratory financial markets because wishful betters appear to possess more favorable information than they actually do. As a consequence, market interaction exacerbates rather than mitigates wishful thinkin...

摘要：The importance of material. flow management for a profit-maximizing. firm has been well articulated in the supply chain literature. We demonstrate in our analytical model that a. firm must also actively manage information. flows within the supply chain, which translates to controlling what it knows, as well as what its competitors and suppliers know. In our model of horizontal competition between an informed and an uninformed. firm with a common upstream supplier, material and information. flo...

摘要：We study a manufacturer that faces a supplier privileged with private information about supply disruptions. We investigate how risk-management strategies of the manufacturer change and examine whether risk-management tools are more or less valuable in the presence of such asymmetric information. We model a supply chain with one manufacturer and one supplier, in which the supplier's reliability is either high or low and is the supplier's private information. On disruption, the supplier chooses ...

摘要：We extend the concept of first-mover advantage to the context of high-technology industries with multiple product generations, and propose that the notion of first-mover advantage needs to be viewed not only through a dynamic lens, but also in conjunction with technological capability. Our main finding is that first-mover advantages are best understood in tandem with the firm's technological capabilities; early entry is beneficial only for pioneers that are technically strong. However, pioneer...

摘要：The silver lining effect predicts that segregating a small gain from a larger loss results in greater psychological value than does integrating them into a smaller loss. Using a generic prospect theory value function, we formalize this effect and derive conditions under which it should occur. We show analytically that if the gain is smaller than a certain threshold, segregation is optimal. This threshold increases with the size of the loss and decreases with the degree of loss aversion of the ...

摘要：We consider how two networked large-scale service systems that normally operate separately, such as call centers, can help each other when one encounters an unexpected overload and is unable to immediately increase its own staffing. Our proposed control activates serving some customers from the other system when a ratio of the two queue lengths ( numbers of waiting customers) exceeds a threshold. Two thresholds, one for each direction of sharing, automatically detect the overload condition and...

摘要：I examine whether technological innovation is a motivating factor in firms' acquisition decisions and how an acquisition (or an acquisition withdrawal) affects technological innovation in subsequent years. I find that firms engaging in acquisition activities are less innovative and have often experienced declines in technological innovation during the years prior to the bid. Among the bidders, the relatively more innovative ones are less likely to complete a deal. During the three years after ...

摘要：We consider a general model of monopoly price discrimination and characterize the conditions under which price discrimination is and is not profitable. We show that an important condition for profitable price discrimination is that the percentage change in surplus (i.e., consumers' total willingness to pay, less the firm's costs) associated with a product upgrade is increasing in consumers' willingness to pay. We refer to this as an increasing percentage differences condition and relate it to ...

摘要：We use heavy-traffic limits and computer simulation to study the performance of alternative real-time delay estimators in the overloaded GI/GI/s+GI multiserver queueing model, allowing customer abandonment. These delay estimates may be used to make delay announcements in call centers and related service systems. We characterize performance by the expected mean squared error in steady state. We exploit established approximations for performance measures with a nonexponential abandonment-time di...
