  摘要：We study the value of information in a supply chain where the manufacturer introduces a direct-selling channel to encroach in the retailer's market. Based on different information structures regarding the direct-selling cost for the manufacturer, we analyze three models: incomplete information model, asymmetric information model, and full information model. By comparing the firms' profits in these models, we derive the value of the manufacturer's information acquisition and the value of sharin...
• Tracking disclosure change trajectories for financial fraud detection AI翻译

  摘要：The global economic disruption brought by COVID-19 crisis can set a stage for the prevalence of financial statement frauds, which jeopardize the efficient functioning of capital markets. In this paper, we propose a nuanced method to detect frauds by tracking granular changes in disclosures over time. Specifically, we first align paragraphs between consecutive disclosures by their similarities. This alignment can be solved as an optimization-based matching problem. Then we identify three types ...

  摘要：The coronavirus disease 2019 (COVID-19) pandemic has disrupted normal operating procedures at transplant centers. With the possibility that COVID-19 infection carries an overall 4% mortality rate and potentially a 24% mortality rate among the immunocompromised transplant recipients, many transplant centers considered the possibility of slowing down and even potentially pausing all transplants. Many proposals regarding the need for pausing organ transplants exist; however, much remains unknown....
• Risk-sensitive Markov decision processes with long-run CVaR criterion AI翻译

  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...
• Learning and skill set formation: A structural examination of version upgrades, user visibility, and AI strategies AI翻译

  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...
• Inventory and financial strategies of capital-constrained firms under limited joint liability financing AI翻译

  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...
• How to operate ship fleets under uncertainty AI翻译

  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...
• Not a box of nuts and bolts: Distribution channels for specialty drugs AI翻译

  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...
• Developing a shared supplier with endogenous spillovers AI翻译

  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'...
• The role of data-based intelligence and experience on time efficiency of taxi drivers: An empirical investigation using large-scale sensor data AI翻译

  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...
