  摘要：We study competition and coordination in a supply chain in which a single supplier both operates a direct channel and sells its product through multiple differentiated retailers. We study analytically the supply chain with symmetric retailers and find that the supplier prefers to have as many retailers as possible in the market, even if the retailers' equilibrium retail price is lower than that of the supplier, and even if the number of retailers and their cost or market advantage prevent sale...

  摘要：The recent surge in the usage of social media has created an enormous amount of user-generated content (UGC). While there are streams of research that seek to mine UGC, these research studies seldom tackle analysis of this textual content from a quality management perspective. In this study, we synthesize existing research studies on text mining and propose an integrated text analytic framework for product defect discovery. The framework effectively leverages rich social media content and quan...

  摘要：We analyze the dynamic price discrimination strategies of a monopolist who offers new services on a subscription basis. Access to customers' subscription histories permits the monopolist to design pricing policies that can be based on customers' past purchase behavior, and on the time period in which they made their purchases. Uncertainty regarding the value of new features, and heterogeneity in consumers' valuation for existing features, creates inter-temporal incentives that influence both p...

  摘要：Quality contracting is critical and challenging due to the many unique issues related to quality. In this study, we analyze the first-mover right in quality contracting by considering two different strategies for the buyer: the quality requirement strategy (QR) where buyer moves first by posting quality requirement to suppliers and quality promise strategy (QP) where buyer voluntarily gives up the first-mover right to suppliers to ask them to promise quality. We study which strategy (1) better...
• Recent Developments in Dynamic Pricing Research: Multiple Products, Competition, and Limited Demand Information AI翻译

  摘要：Dynamic pricing enables a firm to increase revenue by better matching supply with demand, responding to shifting demand patterns, and achieving customer segmentation. In the last 20years, numerous success stories of dynamic pricing applications have motivated a rapidly growing research interest in a variety of dynamic pricing problems in the academic literature. A large class of problems that arise in various revenue management applications involve selling a given amount of inventory over a fi...
• Lower Cost Arrivals for Airlines: Optimal Policies for Managing Runway Operations under Optimized Profile Descent AI翻译

  摘要：Optimized profile descent (OPD) is an operating procedure being used by airlines to improve fuel and environmental efficiency during arrival operations at airports. In this study, we develop a stochastic dynamic programming framework to manage the sequencing and separation of flights during OPD operations. We find that simple calculation based measures can be used as optimal decision rules, and that the expected annual savings can be around $29 million if such implementations are adapted by ma...

  摘要：In this study, we use hourly data on store traffic, sales, and labor from 41 stores of a large retail chain to identify the extent of understaffing in retail stores and quantify its impact on sales and profitability. Using an empirical model motivated from queueing theory, we calculate the benchmark staffing level for each store, and establish the presence of systematic understaffing during peak hours. We find that all 41 stores in our sample are systematically understaffed during a 3-hour pea...
• Mechanisms to Induce Buyer Forecasting: Do Suppliers Always Benefit from Better Forecasting? AI翻译

  摘要：In this study, we consider a supplier's contract offerings to a buyer who may obtain improved forecasts for her demand over time. We investigate how the supplier can take advantage of the buyer's better forecasts and what kind of contracts he should offer to the buyer in order to maximize his profits. We model a natural forecast evolution where the buyer can obtain a more accurate forecast closer to the selling season. We assume there is information asymmetry between the buyer and the supplier...
• Incentive for Peer-to-Peer Knowledge Sharing among Farmers in Developing Economies AI翻译

  摘要：This study examines the peer-to-Peer interactions among farmers when both knowledge learning and sharing are available. We construct a stylized model in which heterogeneous farmers are endowed with their initial production capabilities and can post questions in the platform for help. A representative expert regularly monitors the forum and provides answers to the farmers' questions, but may be non-responsive sometimes due to the limited capacity. A knowledgeable core user (farmer) can choose t...
