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...

摘要：Performance-based contracting is reshaping service support supply chains in capital-intensive industries such as aerospace and defense. Known as ''power by the hour'' in the private sector and as ''performance-based logistics'' (PBL) in defense contracting, it aims to replace traditionally used fixed-price and cost-plus contracts to improve product availability and reduce the cost of ownership by tying a supplier's compensation to the output value of the product generated by the customer (buye...

摘要：In financial risk management, coherent risk measures have been proposed as a way to avoid undesirable properties of measures such as value at risk that discourage diversification and do not account for the magnitude of the largest, and therefore most serious, losses. A coherent risk measure equals the maximum expected loss under several different probability measures, and these measures are analogous to populations or systems in the ranking-and-selection literature. However, unlike in ranking ...

摘要：This paper seeks to provide a ranking of information systems in a setting of contingent monitoring. Control strategies that make the acquisition of additional information conditional on observing certain outcomes largely elude the existing ranking criteria. We show that this happens because contingent monitoring involves more than the classical trade-off between risk sharing and incentives; it also requires a balancing of incentives and downside risk. We then develop a refinement of the most c...

摘要：W e examine whether cooperative planning and uncertainty affect the magnitude of rework in concurrent engineering projects with upstream and downstream operations, and explore the impact of such rework on project delays. Using survey data from a sample of 120 business process (BP) redesign and related information technology (IT) development projects in healthcare and telecommunications, our results indicate that upstream (BP) rework and downstream (IT) rework is mediated and mitigated by coope...
