  摘要：We study the impacts of social interactions on competing firms' quality differentiation, pricing decisions, and profit performance. Two forms of social interactions are identified and analyzed: (1) market-expansion effect (MEE)-the total market expands as a result of both firms' sales-and (2) value-enhancement effect (VEE)-a consumer gains additional utility of purchasing from one firm based on this firm's previous and/or current sales volume. We consider a two-stage duopoly competition framew...
• Demand Pooling in Omnichannel Operations AI翻译

  摘要：Both traditional retailers and e-tailers have been implementing omnichannel strategies such as buy online, pick up at store (BOPS). We build a stylized model to investigate the impact of the BOPS initiative on store operations from an inventory perspective. We consider two segments of customers, namely store-only customers who only make purchases offline and omni-customers who strategically choose between offline and online channels. We show that BOPS may either benefit or hurt the retailer de...
• No Magic for Market Entry in the Field: Evidence from Taxi Markets AI翻译

  摘要：We study taxi markets in Singapore to understand market entry in the field. Although market-entry games in the laboratory consistently produce equilibrium outcomes, we show that a lack of market knowledge hinders the markets from consistently reaching equilibrium in the field. In Singapore, a small, 720-square-kilometre island city that can be divided into 29 taxi markets, full equilibrium is elusive: 68% of the market-entry decisions made by the 2,728 taxi drivers in our data could be improve...

  摘要：In e-commerce warehouses, online retailers increase their efficiency by using a mixed-shelves (or scattered storage) concept, where unit loads are purposefully broken down into single items, which are individually stored in multiple locations. Irrespective of the stock keeping units a customer jointly orders, this storage strategy increases the likelihood that somewhere in the warehouse the items of the requested stock keeping units will be in close vicinity, which may significantly reduce an ...
• Price Discrimination with Fairness Constraints AI翻译

  摘要：Price discrimination strategies, which offer different prices to customers based on differences in their valuations, have become common practice. Although it allows sellers to increase their profits, it also raises several concerns in terms of fairness (e.g., by charging higher prices (or denying access) to protected minorities in case they have higher (or lower) valuations than the general population). This topic has received extensive attention from media, industry, and regulatory agencies. ...
• Risk Guarantees for End-to-End Prediction and Optimization Processes AI翻译

  摘要：Prediction methods are often employed to estimate parameters of optimization models. Although the goal in an end-to-end framework is to achieve good performance on the subsequent optimization model, a formal understanding of the ways in which prediction methods can affect optimization performance is notably lacking. This paper identifies conditions on prediction methods that can guarantee good optimization performance. We provide two types of results: asymptotic guarantees under a well-known F...
• Data Breach Announcements and Stock Market Reactions: A Matter of Timing? AI翻译
  作者：Foerderer, Jens; Schuetz, Sebastian W.

  摘要：Although firms' announcement of data breaches can lead to reputational or operational damages, extant research suggests that stock markets are relatively unresponsive to such announcements. We investigate whether markets' unresponsiveness can be explained by firms strategically timing the announcement to coincide with busy days in the media, thereby reducing attention and, ultimately, attenuating market reactions. We leverage novel data on data breach announcements in the United States between...
• A Theory of Collateral Requirements for Central Counterparties AI翻译
  作者：Wang, Jessie Jiaxu; Capponi, Agostino; Zhang, Hongzhong
  作者单位：Arizona State University; Arizona State University-Tempe; Columbia University
  摘要：This paper develops a framework for designing collateral requirements in a centrally cleared market. Clearing members post collateral-initial margins and default fundsto increase their pledgeable income, thereby committing to risk management. The two types of collateral, however, are not perfect substitutes. By achieving loss mutualization, default funds are economically more efficient than initial margins in aligning members' incentives for risk management ex ante. The optimal mix of collater...
• Dimensioning On-Demand Vehicle Sharing Systems AI翻译

  摘要：We consider the problem of optimal fleet sizing in a vehicle sharing system. Vehicles are available for short-term rental and are accessible from multiple locations. A vehicle rented at one location can be returned to any other location. The size of the fleet must account not only for the nominal load and for the randomness in demand and rental duration but also for the randomness in the number of vehicles that are available at each location because of vehicle roaming (vehicles not returning t...
• Designing Product Development Contracts in the Presence of Managerial Lobbying AI翻译

  摘要：We examine a firm's contract design problem in the context of allocating resources to new products with uncertain potential being developed by the managers vying for funds. The firm faces twin problems of identifying the right project(s) to prioritize them, and next also motivate the managers to exert effort in implementing the project to successful fruition. The firm's contract design can incentivize the managers either using a resource-based incentive plan, which offers a reward based on the...
