摘要：CVaR (Conditional value at risk) is a risk metric widely used in finance. However, dynamically optimizing CVaR is difficult, because it is not a standard Markov decision process (MDP) and the principle of dynamic programming fails. In this paper, we study the infinite-horizon discrete-time MDP with a long-run CVaR criterion, from the view of sensitivity-based optimization. By introducing a pseudo-CVaR metric, we reformulate the problem as a bilevel MDP model and derive a CVaR difference formul...

摘要：For many multiplayer games, including massively multiplayer online role-playing games, consumer skill sets with the game play an important role in engagement. Despite their importance, many aspects of consumers' skill sets are still less well understood. This research considers the formation and evolution of players' skill sets from two perspectives: (1) learning-by-doing, in which a consumer gradually improves his or her skill set with the game from past experiences with other players, and (2...

摘要：This paper studies the operations and financial decisions of two capital-constrained firms via a limited joint liability (LJL) financing scheme offered by a bank with a menu of loan terms including interest rate and leverage ratio/credit line. To explicitly assess the value of LJL financing, we assume that the firms either use LJL financing scheme or traditional individual financing scheme to finance their operations. Under LJL financing scheme, we construct a non-cooperative game model in whi...

摘要：Ships operated by a liner company are scattered around the world to transport goods. A liner company needs to adjust its shipping network every few months by repositioning its ships to respond to uncertain container shipping demand. Few studies investigate a liner company's multiperiod heterogeneous fleet deployment problem under uncertainty, considering fleet repositioning, ship chartering, demand fulfillment, cargo allocation, and adaptive fleet sizes. To this end, this study formulates a mi...

摘要：One of the most important trends in the pharmaceutical industry is the rapid growth of specialty drugs. Specialty drugs, mostly bio based, tend to be high risk, high priced, and more regulated than traditional drugs, resulting in unprecedented challenges in distribution. Such challenges lead to the emergence of specialty distributors (SDs), which, compared with traditional wholesalers (WSs), represent a more controlled channel and carry a smaller variety of drugs. Due to the risky nature of sp...

摘要：Firms who buy from suppliers often engage in supplier development to reduce the supplier's production cost. Being aware that their efforts may benefit a rival firm when there is a shared supplier, some buyers only invest in specific supplier development, that is, in those processes or technologies where spillover cannot occur. Other buyers willingly accept the spillover that arises from supplier development, and invest in generic supplier development. Our game-theoretic model captures a buyer'...

摘要：In this paper, we employ large-scale sensor data to examine the impact of data-based intelligence and work-related experience on the time efficiency of individual taxi drivers, measured by their propensity of choosing the fastest routes. The identification strategy is built on (1) a unique exogenous policy shock-banning taxi-hailing app with an embedded GPS system, and (2) a measure of nonrecurring congestion avoidance, enabled by the real-time sensor data, which serves as a proxy for GPS usag...

摘要：Streaming media companies have changed how contents are consumed, produced, and delivered. This research develops a theoretical model on optimal content policies for streaming media companies in order to maximize customer engagement. We have the following interesting findings. First, in contrast to the results in prior literature that firms produce just enough programs and coverage intervals of the programs do not overlap, we show that placing programs closer can be a better policy for engagem...

摘要：Limited information about the demand for some of the resources needed to produce goods and services (e.g., incomplete and imperfect bills of materials) forces firms to use heuristics when planning resource capacity. We examine the performance of five heuristics: two drawn from practice, two that modify observed approaches, and one motivated by theory. We measure performance as the ratio of the expected cost of supply-demand mismatch from using a heuristic to the value in the full-information s...

摘要：Brick-and-mortar retailers seek higher foot traffic in their stores to improve their sales opportunities. In this quest, location-based advertising on mobile devices has emerged as an important marketing tool for targeting potential customers. The design of such advertising campaigns is complex, and their effectiveness depends on the ability to collect and examine data that aids in targeting the right customers at the right time and place. We develop a campaign design framework that explicitly...
