摘要：The renewed interest among managers and management researchers in stakeholder governance has also underscored the shortage of quantitative methods available for studying business firms as political systems. A critical problem for researchers applying coalition-based theories of organizational politics to observational data is that the units of analysis, coined subcoalitions, are often unobservable. This paper introduces subcoalition cluster analysis (SCA) as a new computational framework for a...

摘要：Many e-commerce platforms have established their warehouses to facilitate the storage and delivery of packages. This paper studies a novel business practice-crosssampling through e-commerce warehouses-that allows physical free samples provided by one (sampling) brand to be distributed with the packages of another unrelated (distributing) brand. In close collaboration with Alibaba, we implement cross-sampling through a large-scale field experiment, in which more than 55,000 free samples are dis...

摘要：This paper establishes the optimal selling mechanism when a seller can incentivize an existing buyer to refer his privately known potential buyer to participate. We identify three optimal channels for providing referral incentives. First, if the existing buyer declares that no potential buyer exists, his virtual value is penalized. Second, if the existing buyer refers the potential buyer to the seller, his virtual value is boosted. Third, in some scenarios where this carrots-and-sticks-via-vir...

摘要：Martin K. Starr, aged 97, passed away January 25, 2025. During his 15-year tenure as editor-in-chief of Management Science, he became the longest serving editor of any INFORMS journal. During this period, he published dozens of books and more than 100 articles. Starr made significant contributions to delineating the domain of modern operations and supply chain management, building a framework for system integration, modular design and production, and high-risk systems. This essay intends to un...

摘要：This paper develops a theoretical framework for network-motivated forbearance lending, or forbearance lending to influential buyers and sellers in a supply network. Because dominant banks in a financial market internalize the negative externality of an influential firm's exit, they may continue to refinance a loss-making influential firm at an interest rate lower than the prime rate. This type of forbearance lending is distinct from other strategies such as evergreening or gambling for resurre...

摘要：Decision makers often simultaneously face many related but heterogeneous learning problems. For instance, a large retailer may wish to learn product demand at different stores to solve pricing or inventory problems, making it desirable to learn jointly for stores serving similar customers; alternatively, a hospital network may wish to learn patient risk at different providers to allocate personalized interventions, making it desirable to learn jointly for hospitals serving similar patient popu...

摘要：When the underlying probability distribution in a stochastic optimization is observed only through data, various data-driven formulations have been studied to obtain approximate optimal solutions. We show that no such formulations can, in a sense, theoretically improve the statistical quality of the solution obtained from empirical optimization. We argue this by proving that the first order behavior of the optimality gap against the oracle best solution, which includes both the bias and varian...

摘要：When returns are partially predictable and trading is costly, utility-maximizing investors track a target portfolio at a constant trading speed. The target portfolio is optimal for a frictionless market, where asset returns are scaled back to account for trading costs and volatilities are adjusted to proxy the execution risk of holding assets that are costly to trade and exposed to volatile states. The trading speed solves an optimal execution problem, which describes how the legacy portfolio ...

摘要：Honest and dishonest behaviors may both diffuse among the members of an organization. Knowing which of the two spreads faster is important because it impacts the extent to which managers will need to resort to other, potentially more costly solutions to curb dishonest behavior. Assessing empirically which of honest behavior or dishonest behavior spreads faster is challenging because this requires field measurements of social relationships and dishonest behavior of individual members, which pos...

摘要：For standard preferences under uncertainty, minimal requirements are proposed to identify cardinal utility and subjective, potentially nonadditive, beliefs. This is achieved through an application of betting consistency. This preference principle says that outcome midpoints derived from preferences over bets on an event are also midpoints when elicited from bets on a different event. This consistency requirement provides a simplified elicitation tool, while it also serves as a robustness test ...
