摘要：As the sharing economy continues to disrupt incumbent services, whether and how incumbents respond to the competition remains largely unknown. We investigate how incumbents can utilize management responses-a managerial intervention to guest reviews-to exploit performance improvement opportunities in guest reviews and sustain competitive advantage facing increased competition from home sharing. Our method integrates quasi-experiments, topic modeling, and deep learning techniques to not only est...

摘要：We develop a general framework for selecting a small pool of candidate solutions to maximize the chances that one will be optimal for a combinatorial optimization problem, under a linear and additive random payoff function. We formulate this problem using a two-stage distributionally robust model, with a mixed 0-1 semidefinite program. This approach allows us to exploit the diversification effect inherent in the problem to address how different candidate solutions can be selected to improve th...

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：Consumers dread shopping during peak hours, and the Covid-19 pandemic has created additional safety concerns about overcrowding in addition to long waiting times. In view of consumer's congestion aversion, should competitive brick-and-mortar grocery stores charge higher prices during congested peak hours to smooth demand? To examine whether and when stores should adopt intraday time-based pricing under competition, we examine a 2-stage dynamic duopoly game. At the beginning of each stage, each...

摘要：One of the major challenges for humanitarian organizations in response planning is dealing with the inherent ambiguity and uncertainty in disaster situations. The available information that comes from different sources in postdisaster settings may involve missing elements and inconsistencies, which can hamper effective humanitarian decision-making. In this paper, we propose a new methodological framework based on graph clustering and stochastic optimization to support humanitarian decision-mak...

摘要：There has been extensive research on the strategic choice between supply chain centralization and decentralization. However, most research assumes complete centralization or complete decentralization but omits the commonly adopted supply chain structure of partial centralization. With partial centralization, a firm owns a portion, but not all, of its partner. To help fill this research gap, in this paper, we make a major contribution by explicitly analyzing partial centralization in a supply c...
