In particular, we analyze the roles of carbon cost deductions and free allowances in such policies. Using free allowances as indicators of CBAM policy intensity, we develop a model representing a manufacturer in an LCRC that serves both export (HCRC) and domestic markets. Our results reveal a CBAM intensity threshold that significantly alters the manufacturer’s CBAM costs and decision-making, yielding two distinct scenarios: Scenario PA (costs incurred above the threshold) and Scenario FA (costs not incurred below the threshold). In Scenario PA, introducing a carbon tax leads to higher emission reduction levels, increased export production, and lower total carbon emissions, despite a decline in domestic sales and profits. Conversely, in Scenario FA, the carbon tax reduces emission reduction levels and export production, increasing total carbon emissions. Importantly, we reveal the dynamic relationship between CBAM policy intensity and optimal carbon tax rates, providing a clear map for how the LCRC government should adjust tax rates as CBAM intensity increases. Specifically, we recommend that the LCRC government adopt a carbon tax only when the CBAM policy intensity exceeds the threshold and progressively increase the tax rate in response to a stronger CBAM. Furthermore, carbon tax revenues should be strategically reinvested in emission reduction technologies to foster sustainable growth for domestic manufacturers.</div></div>","PeriodicalId":19529,"journal":{"name":"Omega-international Journal of Management Science","volume":"138 ","pages":"Article 103383"},"PeriodicalIF":6.7,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144270637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper first studies the impact of a social network on the opaque pricing strategies of a monopolistic merchant in an e-commerce market. We present a two-stage pricing-consumption game in which the merchant and consumers interact on a social network. In this setting, the monopolistic merchant chooses an optimal opaque discount strategy with full knowledge of consumer characteristics and the social network structure. The consumers, facing this opaque pricing policy, purchase optimal amounts of goods based on maximizing utility. Additionally, this paper introduces a series of bounded opaque discount disclosure strategies and determines the optimal strategy for merchants when consumers have different beliefs. Specifically, when consumers have strong beliefs about bounded opaque discounts, merchants should disclose the upper bound of the discount, and when consumer beliefs are weaker, the lower bound should be disclosed. Furthermore, we also explore individual consumer behavioral biases, such as overconfidence and fairness concerns, and their interactions with social networks on merchants’ opaque discount strategies. The findings indicate that merchants can leverage an understanding of consumer social network structures to implement strategic price discrimination targeting consumers with bounded rationality. However, the presence of these behavioral biases does not necessarily lead to an increase in profits gained by merchants through social networks.</div></div>","PeriodicalId":19529,"journal":{"name":"Omega-international Journal of Management Science","volume":"138 ","pages":"Article 103362"},"PeriodicalIF":6.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144270379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the numerous DEA-based FCA studies, a significant category seeks to make all Decision-making Units (DMUs) efficient under a set of common weights after cost allocation, falling under the common-weights FCA framework. However, the classical DEA efficiency evaluation mechanism does not require all DMUs to be evaluated based on a set of common weights. Instead, a DMU is considered efficient if it can choose its favorable weights to achieve an efficiency score of one while ensuring that the efficiencies of other DMUs do not exceed one. Motivated by this, we develop a novel and general efficient FCA framework that allocates the total fixed cost by allowing each DMU to select its preferred weights to be efficient. We prove that the FCA possible set under the traditional common-weights framework is a subset of that under this new framework. Then, an Assurance Region (AR) constraint on fixed costs is introduced to avoid extreme allocation schemes. Moreover, an individual dominance realization strategy and a FCA model based on it are proposed within this framework, aimed at minimizing each DMU’s cross-efficiencies from the perspective of all other DMUs while ensuring its self-assessed efficiency remains at one. Additionally, an algorithm is introduced to guarantee the uniqueness of the FCA scheme. A numerical example and a case study from the Shanghai Automotive Industry Corporation are used to validate the effectiveness of this approach and compare it with other classic methods.</div></div>","PeriodicalId":19529,"journal":{"name":"Omega-international Journal of Management Science","volume":"138 ","pages":"Article 103382"},"PeriodicalIF":6.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144322285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patient stratification at an ED typically relies on the availability of triage information, which assesses patient acuity and is performed by clinical staff. However, triaging takes place after patient registration at the ED, and is prone to delays and interruptions. Delays in administering triage are associated with poor patient care and outcomes, especially for high-acuity patients who need to be admitted from the ED to the hospital. This motivates us, in the paper, to predict the triage category in the pre-triage phase, at the time of registration when patients arrive at the ED. We refer to the predicted triage as <em>TeleTriage</em>, as it can be administered remotely. We then use <em>TeleTriage</em>, along with other relevant features, to model the probability of a patient needing admission from the ED to the hospital. Using machine learning, we focus on the estimation of this admission risk at the time of registration, to enable early identification of patients needing admission, and the start of downstream tasks sooner. We evaluate our modelling approach using internal and external validation schemes across patient conditions, and we accommodate the asymmetric costs of decision-making associated with patient admissions at the ED. We demonstrate that the proposed modelling framework can help reduce the time taken to decide if a patient needs admission, thereby reducing the length of stay for high-acuity patients and mitigating the impact of waiting time targets on admissions.</div></div>","PeriodicalId":19529,"journal":{"name":"Omega-international Journal of Management Science","volume":"138 ","pages":"Article 103381"},"PeriodicalIF":6.7,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144471861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a two-period game model, it analyzes how firms balance the short-term benefits of advertising with its potential long-term drawbacks when making pricing and promotional decisions. The analysis shows that when advertising has positive long-term effects, far-sighted strategies are theoretically optimal regardless of the timing of advertising decisions. In practice, however, startups may struggle to sustain such approaches, as early-stage losses can create financial pressure that pushes them toward short-term survival strategies. When long-term advertising effects are negative, the optimal strategy becomes more sensitive to market conditions. The model shows that in markets with low product substitutability, far-sighted strategies continue to deliver better outcomes. As products become more similar, myopic strategies become more attractive—especially when the negative long-term effects are relatively mild. Furthermore, when the short-term impact of advertising is particularly strong, a myopic strategy can outperform a far-sighted one, even if long-term consequences are unfavorable. Under certain conditions, both firms choosing far-sighted strategies may also lead to a Prisoner’s Dilemma, where mutual restraint results in lower overall profits. These findings highlight the complex trade-offs startups face between short-term gains and long-term viability.

To solve the TSRO-DIU models exactly, an improved column-and-constraint generation algorithm is developed to deal with the bilinear uncertainty of facility disruption and fortification failure. Numerical experiments are conducted to show the importance of considering fortification decisions and fortification failure probability. Furthermore, we demonstrate the flexibility of the TSRO-DDU models under random attack and fortification failure scenarios, compared with the no-fortification model (NFM), the classic successful fortification model (CFM), and the deterministic fortification failure model (DFM).
