  摘要：We study the design of crowdsourcing contests in settings where the outputs of the contestants are quantifiable, for example, a data science challenge. This setting is in contrast to those where the output is only qualitative and cannot be objectively quantified, for example, when the goal of the contest is to design a logo. The literature on crowdsourcing contests focuses largely on ordinal contests, where contestants' outputs are ranked by the designer and awards are based on relative ranks....
• A survey of stochastic inventory models with fixed costs: Optimality of (s, S) and (s, S)-type policies-Discrete-time case AI翻译

  摘要：Fixed costs of ordering items or setting up a production process arise in many real-life scenarios. In their presence, the most widely used ordering policy in the stochastic inventory literature is the (s, S) policy. Optimality of (s, S) policies and (s, S)-type policies have been examined for various inventory models, including those with the inventory level being reviewed in every period or continuously, finite and infinite horizons, discounted-cost and average-cost criteria, backlogging and...
• Optimal robust inventory management with volume flexibility: Matching capacity and demand with the lookahead peak-shaving policy AI翻译

  摘要：We study inventory control with volume flexibility: A firm can replenish using period-dependent base capacity at regular sourcing costs and access additional supply at a premium. The optimal replenishment policy is characterized by two period-dependent base-stock levels but determining their values is not trivial, especially for nonstationary and correlated demand. We propose the Lookahead Peak-Shaving policy that anticipates and peak shaves orders from future peak-demand periods to the curren...
• Competition between P2P ride-sharing platforms and traditional taxis AI翻译

  摘要：Over the past decade, the surge of peer-to-peer (P2P) ride-sharing has significantly cut the market share and profitability for taxis, but taxis remain a major service provider in the personal transportation service industry. This paper analytically examines a market with two segments of consumers based on their travel distances, where a P2P platform and a traditional taxi company have different inconvenience costs and compete for customers through pricing. Our analysis shows that consumers' i...
• Hiding in plain sight: Surge pricing and strategic providers AI翻译

  摘要：Many on-demand service platforms employ surge pricing policies, charging higher prices and raising provider compensation when customer demand exceeds provider supply. There is increasing evidence that service providers understand these pricing policies and strategically collude to induce artificial supply shortages by reducing the number of providers showing as available online. We study a stylized mathematical model of a setting in which an on-demand service platform determines its pricing an...
• Migrant flows: Humanitarian operational aspects of people in transit AI翻译

  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...
