摘要：Consider a firm developing an innovative product. Due to market pressures, production must begin soon after the product development effort is complete, which requires that an upstream supplier invests in capacity while the design of the product and production process are in flux. Because the product is ill-defined at this point in time, the firms are unable to write court-enforceable contracts that specify the terms of trade or the supplier's capacity investment. However, the firms can adopt a...

摘要：In a variety of industries ranging from agriculture to electronics and oil, procurement takes place through a combination of bilateral fixed-price contracts and open market trading among supply chain participants, which allows them to improve supply chain performance by utilizing new demand and cost information. The strategic behavior of the participants in these markets interacts with the way fixed-price contracts are formulated and significantly affects supply chain efficiency. In this paper...

摘要：We study the optimal levels of advertising and promotion budgets in dynamic markets with brand equity as a mediating variable. To this end, we develop and estimate a state-space model based on the Kalman filter that captures the dynamics of brand equity as influenced by its drivers, such as the brand's advertising and sales promotion expenditures. By integrating the Kalman filter with the random coefficients logit demand model, our estimation allows us to capture the dynamics of brand equity a...

摘要：The structure of alliance networks influences their potential for knowledge creation. Dense local clustering provides information transmission capacity in the network by fostering communication and cooperation. Nonredundant connections contract the distance between firms and give the network greater reach by tapping a wider range of knowledge resources. We propose that firms embedded in alliance networks that exhibit both high clustering and high reach (short average path lengths to a wide ran...

摘要：This paper proposes a nonparametric efficiency measurement approach for the static portfolio selection problem in mean-variance-skewness space. A shortage function is defined that looks for possible increases in return and skewness and decreases in variance. Global optimality is guaranteed for the resulting optimal portfolios. We also establish a link to a proper indirect mean-variance-skewness utility function. For computational reasons, the optimal portfolios resulting from this dual approac...

摘要：Bundling, which is the practice of selling two or more products or services in a package, is a pervasive marketing practice and is often used as a strategic competitive tool. However, there has not been enough consideration of competitive bundling situations in which exit of a competitor is not a concern. In this paper, we address this issue by identifying conditions under which strategic competitors may or may not resort to bundling when competitor exit considerations are absent. We study com...

摘要：A growing body of qualitative evidence shows that loss aversion, a phenomenon formalized in prospect theory, can explain a variety of field and experimental data. Quantifications of loss aversion are, however, hindered by the absence of a general preference-based method to elicit the utility for gains and losses simultaneously. This paper proposes such a method and uses it to measure loss aversion in an experimental study without making any parametric assumptions. Thus, it is the first to obta...

摘要：Queueing systems managed by ticket technology are widely used in service industries as well as government offices. Upon arriving at a ticket queue, each customer is issued a numbered ticket. The number currently being served is displayed. An arriving customer balks if the difference between his ticket number and the displayed number exceeds his patience level. We propose a Markov chain model of a ticket queue and develop effective evaluation tools. These tools can help management quantify the ...

摘要：Investment in information technology (IT) is an important driver of economic growth and productivity in the United States and other developed countries, but as yet it is not shown to be a significant driver in developing countries. Previous research suggests that IT investment and complementary assets are insufficient for developing countries to realize economic benefits. This research note examines the factors that influence IT investment in developed and developing countries to determine how...

摘要：In this paper, we revisit and clarify the celebrated machine maintenance and sale age model of Kamien and Schwartz (KS) involving a machine subject to failure. KS formulate and solve the problem as a deterministic optimal control problem with the probability of the machine failure as the state variable. Thus, they obtain deterministic optimal maintenance and sale date. We study two underlying stochastic models with known and random machine modes, and clarify the relationship between the result...
