  摘要：A transaction fee is fundamental in maintaining the stability and decentralization of a permissionless blockchain, the infrastructure underlying major cryptocurrency networks such as Ethereum and Bitcoin. This fee, set and paid by users when initiating each transaction, aggregates to over $24 million daily on Ethereum, imposing a nontrivial barrier to wider adoption. What is worse is that it is disproportionately borne by small users. Like Bitcoin, Ethereum started with a name-your-own-price s...
• Raise the Expectation Bar and Lower the Tolerance? Effects of Being Listed in a Restaurant Guide on Customers' Online Rating Behavior AI翻译

  摘要：Creating curated guides or lists (e.g., Top 100 Places to Eat) is a common operational strategy employed by platforms as part of their reputation systems to assist customers in decision-making. Prior research has largely highlighted the effects of such guides on customer word-of-mouth (WOM) volume and valence. Moving beyond these aggregate WOM metrics, we extend this stream to examine how being listed in a guide (BLG) influences customers' likelihood of providing ratings and rating composition...
• The Value of Blending-Managing Ameliorating Inventory Using Deep Reinforcement Learning AI翻译
  作者：Pahr, Alexander; Grunow, Martin

  摘要：Stocks of some food products, such as whiskey, cheese, or port wine, ameliorate during storage, facilitating product differentiation according to age. This induces a trade-off between immediate revenues and further maturation. Inventory management decisions include purchasing volumes of agricultural produce and production volumes for age-differentiated products. Because products can be blended from stocks of different ages, issuance decisions offer operational flexibility. However, whereas som...

  摘要：While mobility-as-a-service platforms have revolutionized urban transportation and fundamentally transformed travelers' experience and engagement, they encounter a significant challenge in maintaining a temporal and spatial balance between supply and demand, particularly with the inclusion of crowd-sourced freelance drivers. In this study, we propose a hybrid supply-side management problem that accounts for heterogeneous revenue dependent on surge pricing, where surge pricing not only determin...
• Production Planning with Markovian Production Relationships AI翻译

  摘要：We study a production planning problem with linear, nonlinear, deterministic, and/or stochastic production relationships between the production plans and actual production quantities. We start by introducing a stochastic dynamic programing formulation of the problem with a Markovian assumption on the production relationships. Under specific conditions, we establish the convexity of the optimal cost-to-go function and closed forms of optimal policies. To solve the original problem in the genera...
• Scheduling additive manufacturing systems: Complexity and algorithms to minimize the number of late parts AI翻译
  作者：Stott, Michael D.; Sriskandarajah, Chelliah; Stauffer, Jon M.

  摘要：Additive manufacturing (AM) is a process by which three-dimensional products are made via the addition of material in a layer-by-layer fashion. This manufacturing technique is growing in commercial usage, given its advantages in creating very dense or complex geometries as well as highly customizable components. In healthcare, for example, AM can be used to improve patient outcomes by providing timely medical devices (or parts) required for treatments. Minimizing the number of late parts in th...
• Offline Learning and Optimization for Multi-Product Inventory Management With Stockout-Based Substitution AI翻译

  摘要：We deal with a retailer's multi-product inventory system where customers randomly seek acceptable substitutes if their initial requests are not satisfied. Unsuccessful quests for substitutes would result in lost sales. Motivated by a consulting project as well as other real practices, we also choose to deal with further challenges posed by initially unknown base demand distributions and substitution probabilities; moreover, we aim to develop an offline learning method that (i) takes advantage ...
• Entrant Integrative Capability and Incumbent Bias AI翻译

  摘要：In practice, new entrants often bypass intermediary retailers and engage in direct competition against incumbents. However, this might place entrants under the burden of integration costs. This paper models the strategic interactions between an incumbent and an entrant, incorporating the integration cost incurred by the entrant and the associated estimation bias exhibited by the incumbent. In the baseline setting with an unbiased incumbent, we find that the entrant's higher integrative capabil...
• A Ridesharing Platform with an Oversupply of Drivers: Different Assigning Rates or Commission Rates for Drivers? AI翻译

  摘要：This study examines a ridesharing platform's choice among two quality-dependent compensation schemes for drivers when the market is oversupplied, that is, there are more drivers than riders at a given time. We examine an information asymmetric context in which drivers (high and low cost) have different costs to improve service quality, which is private information. The platform designs a menu of contracts for drivers to reveal their type. In the assigning-differentiation compensation scheme, t...

  摘要：This study assesses concentration of the top 50 universities (T50 concentration) in premier business journals and its correlation with journal impact metrics. We use 2008-2022 data from the Web of Science and Clarivate Analytics, focusing on 46 business journals from the University of Texas at Dallas (UTD 24) and Financial Times (FT 50) lists to document several findings. First, we find that the top 50 institutions, representing less than 0.5% of business schools globally, contribute a disprop...
