摘要：We investigate the trade-off between acquisition and retention efforts when customers are sensitive to the quality of service they receive, that is, whether they get timely access to a company's resources when requested. We model the problem as a multi-class queueing network with new and returning customers, time-dependent arrivals, and abandonment. We derive its fluid approximation; a system of ordinary linear differential equations with continuous, piecewise smooth, right-hand sides. Based o...

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：In this study, we examine whether it is optimal to use electric vehicles (EVs) in the car sharing market and investigate the environmental impact of pulling the EVs from the market. We develop a model consisting of a profit-maximizing car sharing company (CSC) and a population of utility-maximizing customers. The CSC sets the number of EVs, the number of fuel vehicles (FVs), and the rental price jointly to maximize its profit. Customers decide whether to use EVs, FVs, or public transportation ...

摘要：Initial deployment decisions are critical to humanitarian organizations as they pre-position resources and prepare for predictable disasters, such as hurricanes, floods, and wildfires. Deploying too few resources results in unmet demand, bad publicity, and unhappy donors. However, deploying a large number of resources can also result in bad publicity and unhappy donors due to high costs and wasted resources when disasters do not occur as expected and deployed items are not managed efficiently....

摘要：Connections across commodity markets create the potential for risk to propagate and for failures to cascade as successive market agents fail. The structure of these networks is, however, often hidden and not directly observable. This article describes methods to uncover this hidden structure and the implications that these hidden connections may have for predicting risk propagation and cascading failures. The results are described in the context of electricity, gasoline, and financial markets....

摘要：Financial and operational risk management are central concepts at the intersection of finance, operations, and commodity risk management. Yet, empirical evidence on their effects on inventory is lacking. We use a fine-grained data set comprising the financial and operational risk management decisions of gold miners from 2003 to 2011 to empirically assess the effects of risk management on inventory. Faced with volatile gold prices, miners may manage (output) risk financially by committing to se...

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：Payment for results (PfR) funding approach, where donors reimburse the non-profit organization (NPO) based on outcomes, is being increasingly adopted in the non-profit sector. However, there is also concern expressed by many voluntary organizations that such a funding approach puts an undue financial burden on small NPOs and could actually be detrimental to social welfare. In this study, we build a theoretical framework to analyze PfR funding mechanisms. We use a sequential game to model the i...
