• Using Social Network Activity Data to Identify and Target Job Seekers AI翻译
  作者：Ebbes, Peter; Netzer, Oded

  摘要：An important challenge for many firms is to identify the life transitions of its customers, such as job searching, expecting a child, or purchasing a home. Inferring such transitions, which are generally unobserved to the firm, can offer the firms opportunities to be more relevant to their customers. In this paper, we demonstrate how a social network platform can leverage its longitudinal user data to identify which of its users are likely to be job seekers. Identifying job seekers is at the h...
• Implementing Environmental and Social Responsibility Programs in Supply Networks Through Multiunit Bilateral Negotiation AI翻译

  摘要：Involving suppliers deep in the supply chain is critical for the success of environmental and social responsibility (ESR) initiatives. Administering ESR programs throughout a complex supply network, however, is challenging. In this paper, we apply a multiunit bilateral bargaining framework to coordinate ESR investments in a general supply network and analyze to what extent an ESR initiator should directly engage the higher-tier suppliers as opposed to delegating that responsibility to the firs...
• Stars and Brokers: Knowledge Spillovers Among Medical Scientists AI翻译
  作者：Mohnen, Myra

  摘要：This paper estimates the heterogeneity in peer effects among research scientists in terms of network position. I propose a new measure, brokerage degree, that determines the extent to which a scientist depends on a coauthor to provide him unique access to other scientists further away. I apply this measure to the coauthorship network of medical scientists. I show that network position is crucial for productivity by facilitating access to nonredundant knowledge. Identification results from vari...
• Implications of Data Anonymization on the Statistical Evidence of Disparity AI翻译
  作者：Xu, Heng; Zhang, Nan
  作者单位：American University
  摘要：Research and practical development of data-anonymization techniques have proliferated in recent years. Yet, limited attention has been paid to examine the potentially disparate impact of privacy protection on underprivileged subpopulations. This study is one of the first attempts to examine the extent to which data anonymization could mask the gross statistical disparities between subpopulations in the data. We first describe two common mechanisms of data anonymization and two prevalent types ...
• Capacity Rationing in Primary Care: Provider Availability Shocks and Channel Diversion AI翻译

  摘要：We study capacity rationing by servers facing differentiated customer classes using data from the Veterans Health Administration, which is the largest integrated healthcare system in the U.S. Using more than 11 million health encounters over two years in which the system was capacity constrained, our study provides a comprehensive analysis of the impacts of provider availability shocks on care channel diversion and delays. The outcomes studied include emergency room (ER) visits broken down by ...
• Personalized Priority Policies in Call Centers Using Past Customer Interaction Information AI翻译
  作者：Hathaway, Brett Alan; Emadi, Seyed Morteza; Deshpande, Vinayak
  作者单位：Johns Hopkins University; University of North Carolina; University of North Carolina Chapel Hill
  摘要：To increase revenue or improve customer service, companies are increasingly personalizing their product or service offerings based on their customers' history of interactions. In this paper, we show how call centers can improve customer service by implementing personalized priority policies. Under personalized priority policies, managers use customer contact history to predict individual-level caller abandonment and redialing behavior and prioritize them based on these predictions to improve o...
• Competition in Congested Service Networks with Application to Air Traffic Control Provision in Europe AI翻译
  作者：Adler, Nicole; Hanany, Eran; Proost, Stef
  作者单位：Hebrew University of Jerusalem; Tel Aviv University
  摘要：We analyze congested network-based markets and their impact on competition, equilibrium charges and efficiency. Several strategies are explored including price caps, mergers and investments in new technologies. We find that congested networks served by collaborating (serial) and competing (parallel) firms may lead to excessive prices. Additionally, oligopolists may only serve captive demand, leading to inefficiently low flows. Perhaps surprisingly, permitting a firm with market power to horizo...
• Personalized Robo-Advising: Enhancing Investment Through Client Interaction AI翻译
  作者：Capponi, Agostino; Olafsson, Sveinn; Zariphopoulou, Thaleia
  作者单位：Columbia University; University of Texas System; University of Texas Austin; University of Texas System; University of Texas Austin; University of Oxford
  摘要：Automated investment managers, or robo-advisors, have emerged as an alternative to traditional financial advisors. The viability of robo-advisors crucially depends on their ability to offer personalized financial advice. We introduce a novel framework in which a robo-advisor interacts with a client to solve an adaptive mean-variance portfolio optimization problem. The risk-return tradeoff adapts to the client???s risk profile, which depends on idiosyncratic characteristics, market returns, and...
• Quantile Connectedness: Modeling Tail Behavior in the Topology of Financial Networks AI翻译
  作者：Ando, Tomohiro; Greenwood-Nimmo, Matthew; Shin, Yongcheol
  作者单位：University of Melbourne; University of Melbourne; Australian National University; University of York - UK
  摘要：We develop a new technique to estimate vector autoregressions with a common factor error structure by quantile regression. We apply our technique to study credit risk spillovers among a group of 17 sovereigns and their respective financial sectors between January 2006 and December 2017. We show that idiosyncratic credit risk shocks propagate much more strongly in both tails than at the conditional mean or median. Furthermore, we develop a measure of the relative spillover intensity in the righ...
• Do Electronic Health Record Systems Increase Medicare Reimbursements? The Moderating Effect of the Recovery Audit Program AI翻译

  摘要：Electronic health record (EHR) systems allow physicians to automate the process of entering patient data relative to manual entry in traditional paper-based records. However, such automated data entry can lead to increased reimbursement requests by hospitals from Medicare by overstating the complexity of patients. The EHR module that has been alleged to increase reimbursements is the Computerized Physician Order Entry (CPOE) system, which populates patient charts with default templates and all...
