摘要：Companies across many industries seek to understand how customer ordering impacts supply chain distribution performance. In the US medical supplies industry, wholesalers are uniquely positioned to use information about downstream customers to study and potentially influence buyer policies and practices due to their industry scale and data visibility. In this study, wholesale medical supplies buyers are first examined based on their ordering practices over a 2-year window using the theoretical ...

摘要：We study the effect of managerial time horizon on two key operations decisions: inventory levels and capacity investment. For identification, we exploit a quasi-natural experiment provided by the staggered adoption of constituency statutes, which alleviate managerial short-termism by providing legal protection to executives adopting a long-term approach in their corporate decisions. Using a staggered difference-in-differences design, we find that, after the reforms, firms incorporated in const...

摘要：Much interest exists in physicians' ability and willingness to adapt their practice styles, as research demonstrates that many physicians practice in ways that are not aligned with the best available scientific evidence. We exploit migration patterns of primary care physicians in Massachusetts over a span of 8 years by tracking physician migrations to practice sites comprised of new peers who shared actual physical working space. We examined whether a patient's likelihood of receiving an inapp...

摘要：Disaster relief workers face unique factors in their operating environments that can inhibit internal integration. For example, disaster relief often involves exposure to traumatic events affecting relief workers' commitment to cooperation and the organization. As such, disaster relief organizations dedicate substantial amounts of scarce resources to support workers exposed to trauma. Unfortunately, contradictory views exist in the literature on how trauma exposure affects commitment and integ...

摘要：The paper proposes an optimization model for the allocation of vaccines to a heterogeneous population composed of several subpopulations with different sizes and epidemiological disease transmission parameters. As the objective, an aggregated function combining a standard utilitarian efficiency criterion with a Gini index-related penalty term is considered. Contrary to previous work, we adopt an outcome equity view: The inequity measure is not based on vaccination fractions or other input fact...

摘要：Near-constant Internet access through desktop or mobile devices has turned self-service support forums into the first port of call for users seeking to troubleshoot product or service issues. The firms providing these products and services also benefit from this trend since it reduces user support costs by diverting service requests away from costlier support channels, such as help desks. For the continued success of such a forum, however, the managing entity must ensure that users receive tim...

摘要：Product evaluation is an essential business process, and digital innovation has made it possible for companies to immediately process available information. We develop a model where a company continuously assesses information that follows a doubly stochastic Poisson process with a mean-reverting and stochastic intensity. Accordingly, the company faces a two-dimensional optimal stopping problem in which the company continues to evaluate the product if and only if the product reputation and info...

摘要：Over the past decade, the surge of peer-to-peer (P2P) ride-sharing has significantly cut the market share and profitability for taxis, but taxis remain a major service provider in the personal transportation service industry. This paper analytically examines a market with two segments of consumers based on their travel distances, where a P2P platform and a traditional taxi company have different inconvenience costs and compete for customers through pricing. Our analysis shows that consumers' i...

摘要：Many on-demand service platforms employ surge pricing policies, charging higher prices and raising provider compensation when customer demand exceeds provider supply. There is increasing evidence that service providers understand these pricing policies and strategically collude to induce artificial supply shortages by reducing the number of providers showing as available online. We study a stylized mathematical model of a setting in which an on-demand service platform determines its pricing an...

摘要：We address a production/inventory problem for a single product and machine where demand is Poisson distributed, and the times for unit production and setup are constant. Demand not in stock is lost. We derive a solution for a produce-up-to policy that minimizes average cost per unit time, including costs of setup, inventory carrying, and lost sales. The machine is stopped periodically, possibly rendered idle, set up for a fixed period, and then restarted. The average cost function, which we de...
