摘要：Fairness is a natural concern when model-based decisions affect human beings. In personnel-management decisions, employees' perceptions of fairness depend both upon the decision processes as well as the resulting outcomes. Acting as a key part of decision processes, operational models often emphasize equality, or sameness, of outcomes among individuals. Fair outcomes, as a manifestation of distributive justice, involve balancing two competing aspects: equality and equity. Equity, in opposition...

摘要：We consider the classical appointment scheduling problem that does not have a session length constraint. The decision is to determine job allowances to minimize total expected weighted costs of waiting times of jobs and idle times of the service provider. In particular, we study a simple yet effective scheduling policy-the so-called constant policy, which allocates a constant job allowance for each appointment. Prior studies on appointment scheduling suggest a dome-shaped structure for the opt...

摘要：In laboratory experiments, we compare the performance of short-term and long-term contracts in a two-period supplier-buyer dyad with asymmetric cost information. We find that buyers tend to reject offers if the payoff inequality increases from one period to the next. We coin this dynamic form of inequity aversion as ratcheting aversion. We show that under short-term contracting, the buyer's ratcheting aversion limits the supplier's leeway to exploit information revelation in earlier periods be...

摘要：US coal-fired generating capacity has shed nearly 25% of its footprint between 2011 and 2018. Multiple factors-regulation, natural gas prices, renewable energy adoption, and environmental activism-have each been lauded by various stakeholders for this trend. To improve our understanding of this environmental technology transition, it is important to determine the extent to which each of these factors has accelerated coal unit retirements. We do so in this study through an accelerated failure t...

摘要：Data center networks provide the physical infrastructure that hosts Internet-related services and cloud computing. Designing data center networks properly is imperative for Internet-related service and cloud computing providers to gain competitive edges through cost efficiency and service quality. In this study, we formulate a mathematical programming model to address the data center network design problem, in which the objective is to minimize total operating cost and the service delay penalt...

摘要：Research suggests that increased reliance on digital sources (e.g., blogs, social media, online forums) exhibited by the emerging millennial workforce may affect procurement decisions. These arguments contend with studies which indicate that organizational buyers rely on decision shortcuts (e.g., brand, loyalty, and peer opinions) to mitigate risk or to simplify purchase decisions. One can argue that buyers gain more information from digital sources, which may attenuate the role of these short...

摘要：We argue that in analyzing panel-data econometric models, researchers rely excessively on statistical criteria to determine model specification, treating it primarily as a matter of statistical inference. This inferential emphasis is most obvious in the common practice of using statistical tests (e.g., the Hausman test) to choose between fixed- and random-effects specifications, often ignoring the assumptions underpinning these tests. For instance, the Hausman test depends on the true within-p...

摘要：Studies show that merchants are heterogeneous in profitability from offering promotions on third-party-online-promotion marketplaces who often charge a single commission rate. Using a data analytics system, a marketplace can classify merchants according to their heterogeneous characteristics and offer merchant-type specific commission rates. In this study, we construct a game-theoretic model consisting a marketplace with two types of merchants who have heterogeneous proportion of consumers who...

摘要：Conceptualized as a meta-construct, operations-related structural flux (ORSF) refers to appointments and exits-voluntary or involuntary-of operations-related executives, to and from the firm. This research leverages the contingency theory perspective to show that ORSF's influence on firm performance is contingent on contextual circumstances of such executive changes, specifically, appointments and exits-voluntary or involuntary. Examining executive turnover data from North American public firm...
