  摘要：We study a risk-averse newsvendor problem where demand distribution is unknown. The focal product is new, and only the historical demand information of related products is available. The newsvendor aims to maximize its expected profit subject to a profit risk constraint. We develop a model with a value-at-risk constraint and propose a data-driven approximation to the theoretical risk-averse newsvendor model. Specifically, we use machine learning methods to weight the similarity between the new...
• Applications of Stochastic Orders and Stochastic Functions in Inventory and Pricing Problems AI翻译

  摘要：Uncertainties involved in decision making often impose challenges to our ability of modeling and analyzing the reality. The purpose of this study is to demonstrate how one can go beyond the conventional optimization thinking, via taking a stochastic viewpoint, to push the boundaries of the analysis. We review the basic notions of stochastic orders and stochastic functions, with which the conventional (deterministic) way of modeling can be generalized. Based on the orders among distribution fun...
• Why do Energy Markets in Europe Rely on One Instrument? AI翻译

  摘要：A common feature to electricity markets with derivative contracts is that the traded contracts are almost only futures and that they are traded multiple times the overall electricity demand. To understand why this occurs in practice, we study the efficiency of risk aligning in the competitive energy industry through derivative contract trading. We derive conditions that need to hold for a contract to provide the most efficient risk aligning, among all possible derivative contracts imaginable. ...

  摘要：Business rivals often collaborate on specific aspects of their operations in order to achieve cost efficiency. To better understand and manage such an operational collaboration, we formulate a multi-stage duopoly competition model to study the strategic and welfare implications of a cost-reducing cooperation between competing firms. Without any additional agreement beyond the collaborative effort in deterministic cost reduction, we characterize intuitive conditions under which there exists a u...
• Minimizing conditional value-at-risk under a modified basestock policy AI翻译

  摘要：Consider a single-product, make-to-stock, risk-averse company that manages its finished goods inventory by a basestock policy. Item demand is modeled as a Poisson process, and unit production time is modeled as an exponential random variable. Annual cost is equal to the sum over one year of the inventory-holding and back-ordering costs. The company wants to minimize the annual cost conditional value-at-risk by an appropriate basestock selection called the optimal basestock. After offering evid...
• Coping with Demand Uncertainty: The Interplay between Dual Sourcing and Endogenous Partial Backordering AI翻译

  摘要：In some stockout situations, a retailer may be better off declining to fulfill some demand even though it could have been backordered. We study the conditions under which endogenous (retailer-driven) partial backordering is the cost-minimizing strategy in an infinite horizon periodic review inventory system with dual sourcing. At the beginning of each period, the retailer can place two orders. The first order (with higher unit purchase cost) is delivered immediately from the fast supplier and ...
• Achieving equitable food security: How can food bank mobile pantries fill this humanitarian need AI翻译

  摘要：Hunger occurs in all locations around the globe, from developing to developed countries. In fact, there were over 37 million food insecure individuals (those without access to consistent nutritious food) in the United States in 2018, and this number increased in recent years due to the COVID pandemic. In many countries, food banks are used to consolidate food donations from individuals or government agencies and then provide that food to local partner agencies (such as food pantries and soup k...
• Crop minimum support price versus cost subsidy: Farmer and consumer welfare AI翻译
  作者：Chintapalli, Prashant; Tang, Christopher S.

  摘要：Besides using earmark budget to support farmer cost subsidies, governments in many developing countries use minimum support price (MSP) as an alternative subsidy scheme to (i) safeguard farmers' incomes against vagaries in crop price and (ii) ensure sufficient crop production. Among different MSP schemes, we focus on the credit-based MSP scheme under which a government will not take any possession of a crop; instead, it will credit farmers if the prevailing market price is below the prespecifi...
• How consumers value retailer's return policy leniency levers: An empirical investigation AI翻译
  作者：Abdulla, Huseyn; Abbey, James D.; Ketzenberg, Michael
  作者单位：Texas A&M University System; Texas A&M University College Station; Mays Business School
  摘要：Due to the ongoing and dramatic growth in the volume of consumer returns, retailers continue to struggle with the trade-off in returns service strategies between implementing stricter return policies to lower operational costs and environmental footprint versus providing customers with lenient return policies to positively stimulate customers' value perceptions and patronage intentions. This paper argues that effective management of this trade-off requires a deep understanding of the process t...
• Customer Bargaining Power, Strategic Fit, and Supplier Performance AI翻译

  摘要：Prior studies report mixed evidence on the impact of customers' bargaining power on supplier performance. We shed light on this mixed evidence by considering the moderating role of strategic fit. A strategically aligned supplier can provide long-term benefits to the customer. As a result, powerful customers may trade off the short-term benefits obtained through supplier concessions with the long-term benefits derived from strategic fit. Thus, strategic fit can mitigate the negative impact of c...
