• I Quit: Schedule Volatility as a Driver of Voluntary Employee Turnover AI翻译
  作者：Bergman, Alon; David, Guy; Song, Hummy
  作者单位：University of Pennsylvania; University of Pennsylvania
  摘要：Problem definition: Employers across many sectors of the economy have been fast to adopt variable work scheduling policies. The cost of this flexibility for employers is usually borne by employees, for whom unstable work schedules create several disruptions. In the context of home healthcare, we examine how employer-driven volatility in nurses' schedules impacts their decision to voluntarily leave their job. Methodology/results: Using an instrumental variables approach, we causally identify th...
• Market Segmentation Trees AI翻译

  摘要：Problem definition: We seek to provide an interpretable framework for segmenting users in a population for personalized decision making. Methodology/results: We propose a general methodology, market segmentation trees (MSTs), for learning market segmentations explicitly driven by identifying differences in user response patterns. To demonstrate the versatility of our methodology, we design two new specialized MST algorithms: (i) choice model trees (CMTs), which can be used to predict a user's ...
• Vehicle Rebalancing in a Shared Micromobility System with Rider Crowdsourcing AI翻译

  摘要：Problem definition: Shared micromobility vehicles provide an eco-friendly form of short-distance travel within an urban area. Because customers pick up and drop off vehicles in any service region at any time, such convenience often leads to a severe imbalance between vehicle supply and demand in different service regions. To overcome this, a micromobility operator can crowdsource individual riders with reward incentives in addition to engaging a third-party logistics provider (3PL) to relocate...
• Intertemporal Price Discrimination via Randomized Promotions AI翻译
  作者：Chen, Hongqiao; Hu, Ming; Wu, Jiahua
  作者单位：Nanjing University; University of Toronto; Imperial College London
  摘要：Problem definition: The undesirable but inevitable consequence of running promotions is that consumers can be trained to time their purchases strategically. In this paper, we study randomized promotions, where the firm randomly offers discounts over time, as an alternative strategy of intertemporal price discrimination. Methodology/results: We consider a base model where a monopolist sells a single product to a market with a constant stream of two market segments. The segments are heterogeneou...
• Can Global Sourcing Strategy Predict Stock Returns? AI翻译
  作者：Jain, Nitish; Wu, Di (Andrew)
  作者单位：University of London; London Business School; University of Michigan System; University of Michigan
  摘要：Problem definition: Whereas firms are increasingly relying on sourcing globally as a key constituent of their supply chain strategy, there is no empirical evidence on whether investors of these firms adequately reflect firms' global sourcing strategy (GSS) in their stock-valuation process. In this paper, we empirically test whether stock market participants are efficient in doing so. Methodology/results: Using the empirical asset-pricing framework, we find that information concerning firms' GS...
• The Impact of Behavioral and Economic Drivers on Gig Economy Workers AI翻译
  作者：Allon, Gad; Cohen, Maxime C.; Sinchaisri, Wichinpong Park
  作者单位：University of Pennsylvania; McGill University; University of California System; University of California Berkeley
  摘要：Problem definition: Gig economy companies benefit from labor flexibility by hiring independent workers in response to real-time demand. However, workers' flexibility in their work schedule poses a great challenge in terms of planning and committing to a service capacity. Understanding what motivates gig economy workers is thus of great importance. In collaboration with a ride-hailing platform, we study how on-demand workers make labor decisions; specifically, whether to work and work duration....
• The Value of Social Media Data in Fashion Forecasting AI翻译
  作者：Fu, Youran; Fisher, Marshall
  作者单位：Amazon.com; University of Pennsylvania
  摘要：Problem definition: How to use social media to predict style color and jeans fit sales for a retailer. Academic/practical relevance: Neither retail practice nor the academic literature provides a method for using social media to predict style color and jeans fit sales for a retailer. We present and validate a systematic approach for doing that. Methodology: Demand forecasting in the fashion industry is challenging due to short product lifetimes, long manufacturing lead times, and constant inno...
• The Winner's Curse in Dynamic Forecasting of Auction Data: Empirical Evidence from eBay AI翻译

  作者单位：McGill University; Alphabet Inc.; Google Incorporated; Amazon.com; University of Texas System; University of Texas Dallas
  摘要：Problem definition: Dynamic forecasting models in auctions have fallen short on two dimensions: (i) the lack of an equilibrium model for final bids and (ii) the lack of a winner's curse (i.e., a tendency to overpay conditional on winning the auction) adjustment to allow bidders to account for a common value component in the auction item. In this paper, we develop a methodology to accurately predict equilibrium stage bids from the initial bidding dynamics and quantify the impact of the winner's...
• Blockchain Operations in the Presence of Security Concerns AI翻译
  作者：He, Jiahao; Zhang, Guangyuan; Zhang, Jiheng; Zhang, Rachel Q.
  作者单位：Hong Kong University of Science & Technology
  摘要：Problem definition: A blockchain payment system, such as Bitcoin or Ethereum, validates electronic transactions and stores them in a chain of blocks without a central authority. Miners with computing power compete for the rights to create blocks according to a preset protocol, referred to as hashing or mining, and, in return, earn fees paid by users who submit transactions. Because of security concerns caused by decentralization, a transaction is confirmed after a number of additional blocks a...
• Redesigning Sample Transportation in Malawi Through Improved Data Sharing and Daily Route Optimization AI翻译

  作者单位：Massachusetts Institute of Technology (MIT); Indian School of Business (ISB); Massachusetts Institute of Technology (MIT); Northwestern University
  摘要：Problem definition: Healthcare systems in resource-limited settings rely on diagnostic networks in which medical samples (e.g., blood, sputum) and results need to be transported between geographically dispersed healthcare facilities and centralized laboratories. Academic/practical relevance: Existing sample transportation (ST) systems typically operate fixed schedules, which do not account for demand variability and lead to unnecessary transportation visits as well as delays. Methodology: We d...
