  摘要：The increasing frequency of traffic accidents involving food delivery drivers has raised public concern about the safety of fast delivery services. In response, food delivery platforms have introduced two corporate social responsibility (CSR) strategies to enhance drivers' road safety: One in which the platform assumes full responsibility for extending delivery times and another that empowers consumers to decide on extended delivery times. Additionally, policymakers are mandating that platform...
• Multi-Agent Deep Reinforcement Learning for Multi-Echelon Inventory Management AI翻译

  摘要：We apply heterogeneous-agent proximal policy optimization (HAPPO), a multi-agent deep reinforcement learning (MADRL) algorithm, to the decentralized multi-echelon inventory management problems in both a serial supply chain and a supply chain network. We also examine whether the upfront-only information-sharing mechanism used in MADRL helps alleviate the bullwhip effect. Our results show that policies constructed by HAPPO achieve lower overall costs than policies constructed by single-agent dee...

  摘要：In 2019, self-employed individuals in the United States owned and operated more than 27 million nonemployer firms and generated more than $1.3 trillion in revenue. Our study examines how self-employed workers adjust their operations in response to an exogenous regulatory change that places limits on how they can utilize their productive assets. Extending modern property rights theory of the firm (PRTF), we studied how self-employed for-hire truck drivers modified their operations in response t...
• Data-Driven Shelf Stocking: Robustness and Vertical-Location Effect AI翻译

  摘要：In this article, we study a shelf-stock allocation problem in a data-driven setting where the demand distribution is unknown. The retailer needs to decide which commodities to place on each level of the shelf (location decision), and determine the stock level for each selected commodity at the shelf (stock decision) that can be adjusted based on updated demand prediction, under constraints on allocation and capacity, so as to maximize total expected profit. Key issues of the problem include de...

  摘要：Driven by climate change and overuse, water stress is a worsening sustainability concern that threatens businesses and communities across the globe. Leading global organizations such as the United Nations have expressed an urgent need for sustainable water management strategies across nations and economies. Yet, the field of supply chain management does not have a substantial research stream related to water. A key challenge is the lack of a persuasive organizing framework within this setting....

  摘要：The indirect productivity gains related to information technology (IT), known as IT externalities, in inter-firm contexts have been extensively studied. However, the impact of IT investments within a business unit (BU) of a multibusiness firm on the productivity of other BUs remains unclear. Additionally, the conditions that facilitate such intra-firm externalities are not well understood. Research on resource externalities within multibusiness firms typically focuses on capacity-sharing benef...

  摘要：Over the past two decades, there has been a rise in localized terrorist organizations that have seized control of geographical regions, leading to intricate spatial topological relations between areas controlled by terrorists and those populated by civilians. Given the complexity and duration of counter-terrorism operations, governments must continually adapt their strategies to defeat terrorists in diverse geographical configurations. These operations can be protracted and expensive, with num...

  摘要：Leveraging government tax incentives to prompt corporate charitable giving has gained considerable popularity over the past decade. This paper sheds light on the broader consequences of the U.S. government's tax-subsidy policy for charitable food donations, which is determined based on the fair market value (FMV) of the donated products. We incorporate the tax-subsidy into a monopolist food retailer's after-tax profit function. Market demand is both price- and quality-dependent, and the shelf-...

  摘要：Up to 40% of the food supply in the U.S. goes uneaten while one in nine individuals struggle to put enough food on their table. Food banks serve an important role in addressing food insecurity by matching the supply of excess food with the demand from the food-insecure population. They collect in-kind donations (non-discretionary food), often perishable and highly variable in their quality, quantity, content, and timing, and then distribute these donations to serve the needs of the food-insecu...
• Simultaneous Search, Reservation Fees, and Sequential Outcomes AI翻译
  作者：Chen, Ying-Ju
  作者单位：Hong Kong University of Science & Technology
  摘要：This paper studies a simultaneous-search problem in which a player observes the outcomes sequentially, and must pay reservation fees to maintain eligibility for recalling the earlier offers. We use postgraduate program applications to illustrate the key ingredients of this family of problems. We develop a parsimonious model with two categories of schools: Reach schools, which the player feels very happy upon joining, but the chance of getting into one is low; and safety schools, which are a sa...
