  摘要：Millions of workers in India who migrated to cities for employment have transited back to seek refuge in their home villages, causing disruptions in both cities and villages. This type of mass flow of migrants in transit represents a humanitarian crisis. Understanding migrant flow patterns and ways to ameliorate the conditions for migrants in transit is critical to managing the humanitarian crisis. In this study, we develop a model that examines the influence of migrant networks, inter-organiz...

  摘要：The rapid development of blockchain has inspired many traditional centralized intermediaries to transform their transaction models, especially for the peer-to-peer market. Lately, the token-based (blockchain) system (with cryptocurrency) is gaining popularity. However, little is known about the (comparative) performance of different operating types. In this study, we build an analytical framework to find the optimal strategies for the token-based and nontoken-based blockchain (as a special app...
• Impact of conflict delisting and relisting on remaining products in retail stores: Sales gains across products categories and spillovers to nearby stores AI翻译

  摘要：Disputes between retailers and manufacturers often result in the retailer delisting the manufacturer's products, which dramatically alters competition in the retail market. When rival products are temporarily delisted, the products remaining on retail shelves are expected to gain sales due to substitution. However, it is unclear how much sales gain of remaining products can be expected, how long the sales gain persists after the rival products are relisted, whether the sales gain varies in dif...
• Optimal selling scheme in social networks: hierarchical signaling, sequential selling, and chain structure AI翻译

  摘要：We study the optimal selling scheme when a seller sells a product/service with a positive consumption externality, and customers are uncertain about the product's/service's value. Because early adopters learn this value, we consider the customers' intrinsic signaling incentives and positive feedback effects. Allowing the seller to choose the sequence of customers' decisions (as an endogenous hierarchy) implies that signaling takes place in multiple rounds. To tackle this hierarchical signaling...

  摘要：This paper investigates how managers in the upstream firm (i.e., supplier) adjust their allocations of cost resources in response to managerial expectations of the downstream firms (i.e., customers) on the future demand and prospects. We conduct an empirical analysis to examine the impact of the tone of customers' forward-looking disclosures (FLDs) contained in the Management Discussion and Analysis section of 10-K filings on suppliers' asymmetric cost behaviors, characterizing costs decreasin...
• Coordinating traditional media advertising and online advertising in brand marketing AI翻译

  摘要：Researchers in the marketing and operations management literature have investigated the issue of making optimal media planning decisions for advertising. Brand marketers have recently begun using online intent advertising (OIA), which is online advertising such as search or display advertising targeted at consumer intent, for brand building. Unlike traditional media advertising, OIA is sold through an auction of indicators of consumer intent such as keyword phrases. This practice raises questi...
• Economic production with Poisson demand, lost sales, fixed-rate discrete replenishment, and a constant setup time AI翻译

  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...
• Designing contests for data science competitions: Number of stages and the prize structures AI翻译

  摘要：Firms have been proactively holding data science competitions via online contest platforms to look for innovative solutions from the crowd. When firms are designing such competitions, a key question is What should be a better contest design to motivate contestants to exert more effort? We model two commonly observed contest structures (one stage and two stage) and two widely adopted prize structures (high spread and low spread). We employ economic experiments to examine how contest design affe...
• A semiparametric Bayesian model for queueing arrival processes: An application to call centers AI翻译

  摘要：Nonhomogeneous Poisson process models have commonly been used to analyze and forecast arrivals. Such processes require specification of intensity (arrival rate) functions, which are typically defined in a parametric form. The accuracy of the parametric models is highly sensitive to the choice of the specific intensity function for the arrival process. We use a Bayesian framework by proposing a nonparametric form for the intensity function and introduce a robust semiparametric model. The model ...
• Should the fox guard the henhouse? Category captainship arrangement as a strategic information transmission mechanism AI翻译

  摘要：Retailers may collaborate with key suppliers to manage some specified categories. This collaboration is often formalized as a captainship arrangement between the retailer and her leading supplier in the category. The designated category captain assists the retailer with category management decisions. We show that captainship arrangements have the potential to generate a valuable information effect for the retailer: nonprice decisions by the category captain can reveal information that allows t...
