摘要：As firms continue to abandon pensions in favor of employee-managed retirement plans, tremendous demands are being placed on the decision-making proficiency of future retirees. As reflected in the equity premium puzzle, individual investors tend to hold overly conservative portfolios that provide meager payoffs over time. Consequently, there is growing concern that the vast majority of retirement accounts might be insufficiently funded when employees reach retirement. Given that most retirement...

摘要：This paper examines the effect of recommender systems on the diversity of sales. Two anecdotal views exist about such effects. Some believe recommenders help consumers discover new products and thus increase sales diversity. Others believe recommenders only reinforce the popularity of already-popular products. This paper seeks to reconcile these seemingly incompatible views. We explore the question in two ways. First, modeling recommender systems analytically allows us to explore their path-de...

摘要：It is commonly argued that in recent years pharmaceutical companies have targeted their research and development (R&D) at small improvements of existing compounds instead of riskier drastic innovations. In this paper, we show that the bias in the pharmaceutical industry toward small innovations might be driven by the low sensitivity of the demand. In particular, small innovations get a proportionally larger reward because pharmaceutical firms target them at the inelastic segments of the demand...

摘要：Previous research suggests firms can build a market share advantage by preempting later entrants with a broad product line and expanding rapidly into related markets. Whether such a strategy leads to a pioneering profit advantage relative to followers also depends on its cost effects. In this paper, we examine when the market share advantage of a pioneering firm with a broad product line strategy translates into a profit advantage by examining the cost effects of this strategy. Using the profi...

摘要：We conceptualize strategic decision-making processes within a manufacturing firm as streams of resources allocated to short-and long-term changes. The analogous ecological model, referred to as the Lotka-Volterra model, captures this dynamic tension between decisions made by the firm and its manufacturing operations. This representation leads to evolutionarily stable manufacturing strategies (ESMSs), which contribute to a firm's competitive advantage in different ways. Using a random sample of...

摘要：This paper analyzes a waiting line system that is motivated by the operations of border-crossing stations between the United States and Canada. There are two main conflicting goals in such a system: high security level, which often leads to a longer line; and good customer service, which requires a shorter line. Thus, unlike other queueing systems, maintaining the average queue length within a certain range is the primary objective. This is achieved using a staffing policy, called congestion-b...

摘要：Recent product introductions such as the Xbox 360, Sony Playstation 2, and PT Cruiser have been characterized by shortage of these products. Some experts have suggested that such scarcity can be a deliberate strategy for making the product more desirable. In this paper, we empirically examine the relationship between introductory inventory levels and consumer preference in the U. S. automobile industry and show that relative scarcity of a car at the time of introduction is associated with high...

摘要：Many markets that have traditionally relied on collocation of buyers, sellers, and products have introduced electronic channels. Although these electronic channels may provide benefits to buyers and sellers by lowering the transaction costs of participating in the market, there are trade-offs related to quality uncertainty and increased risk that may limit the adoption of the electronic channels. As a result, buyers and sellers use physical channels for some transactions and electronic channel...

摘要：Studies of career dynamics implicitly claim that government employees are not entrepreneurial. Utilizing longitudinal data from the U. S. Panel Study for Income Dynamics, we investigate the reasons for the low rate of entrepreneurship from the public sector. We conjecture that it is due to labor market matching processes and the bureaucratic nature of public organizations and bureaucratization of individuals. Our life-course analysis identifies labor market matching as a major determinant: non...

摘要：Estimating quantile sensitivities is important in many optimization applications, from hedging in financial engineering to service-level constraints in inventory control to more general chance constraints in stochastic programming. Recently, Hong (Hong, L. J. 2009. Estimating quantile sensitivities. Oper. Res. 57 118-130) derived a batched infinitesimal perturbation analysis estimator for quantile sensitivities, and Liu and Hong (Liu, G., L. J. Hong. 2009. Kernel estimation of quantile sensiti...
