We develop a modular framework that cleanly separates solving a renter's decision problem from estimating utility. We consider renters with varying degrees of sophistication and alertness to buyout offers. Using washer, dryer, and mattress data from a prominent RTO firm, for each decision model, we estimate utilities and the probabilities of abandoning the rental, neglecting the buyout offer, and considering the buyout offer. We find that renters have short decision horizons and frequently neglect buyout offers. Also, their utilities remain stable throughout the rentals. Moreover, renters who opt for rental agreements with higher rental fees or longer terms tend to have higher ownership utilities. Based on our counterfactual analyses, for washer or dryer renters, we suggest initiating efforts to remind renters of buyout offers. In contrast, for mattresses, whose renters more frequently consider buyout offers, we find that profits would be increased by setting prices higher.</p>\u0000 </div>","PeriodicalId":51097,"journal":{"name":"Journal of Operations Management","volume":"71 8","pages":"1165-1184"},"PeriodicalIF":10.4,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145646799","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}

First, comparing misinformation diffusion between the decentralized Steemit and the centralized Pokec platforms suggests that in the absence of any mitigation mechanisms, misinformation in decentralized platforms affects more users, at faster rates, and reaches shorter distance from the misinformation initiating user. Second, within the decentralized platforms, misinformation affects fewer users, at slower rates, and reaches shorter distance from the misinformation initiating user in the presence of mitigating mechanisms than in their absence.

This reduces the need for virgin materials to manufacture new units and wastage from used units. However, it is well known that delays in inventory returns often lead managers to make suboptimal ordering decisions. This problem is particularly significant in CE systems, where inadequate inventory management can significantly reduce or even negate the benefits of CE. The existing literature lacks evidence on the magnitude of this issue and its key contributing factors. Addressing this gap is essential for developing operational details and maximizing the benefits of CE systems. Using a novel complexity ordering based on a formal characterization of the reverse flow of goods, we investigate the efficiency of managerial decision-making. In our experimental study, participants made inventory replenishment decisions in various CE systems that differed in the complexity of reverse flow. We found that participants' operating costs were substantially higher than the simple benchmark costs, and as the CE system became more complex in reverse flow, the suboptimality of managerial decision-making worsened.

We address this issue empirically by conducting a quasi-natural experiment in the United States in which certain states have enacted relevant laws that increase in-state firms' propensity to adopt and use smart contracts. Our difference-in-differences estimation suggests that compared with out-of-state control firms, in-state treatment firms' operational efficiency increases significantly after the enactment of smart contract laws. Our post hoc analysis further suggests that state-level smart contract laws help increase in-state firms' actual smart contract activities, which in turn lead to operational efficiency improvement. We also find that the operational efficiency improvement varies across firms with different supply chain complexities. While firms with a large number of supply chain partners (i.e., high horizontal complexity) gain more operational efficiency improvement, the improvement becomes less pronounced if firms' supply chain partners are distributed across different countries (i.e., high spatial complexity).

Through an in-depth, longitudinal case study, we identify three interrelated governance contradictions—regarding ownership, trust, and growth—that triggered destabilizing oscillations between centralized and decentralized governance modes. We introduce the concept of <i>semirigid limits</i> to capture the bounded flexibility within which governance can be made and adapted under such paradoxical conditions. Our findings show that the centralization–decentralization paradox is especially difficult to navigate when strategic boundary conditions—here, industry competition, fragmented coordination, and high interdependencies—are present.

Establishing and maintaining robust connections with a diverse array of stakeholders—including suppliers, customers, third-party service providers, regulatory bodies, external research and development (R&D) organizations, and academic institutions such as universities, has become essential. An interorganizational view of operations is fundamental to an accurate understanding of the context in which process development and improvement occurs, and therefore, the potential for operational actions to generate tangible outcomes. By working collaboratively with these external entities, firms can not only optimize operational performance but also foster innovation, adaptability, and sustained competitive advantage. Thus, researching the drivers, processes, and outcomes of interorganizational operations at different levels of organizations is central to the mission of the Journal of Operations Management.</p><p>While there is no formal definition of inter-organizational operations (IOO) in the operations and supply chain management literature, several related definitions exist. At JOM, we adopt the perspective provided by Oliver (<span>1990</span>), and akin to that of Dyer and Singh (<span>1998</span>), defining inter-organizational relationships as the transactions, flows, and linkages that underlie the relationships between operations in different organizations that collaborate in networks to achieve shared goals.</p><p>The landscape of interorganizational operations thus includes suppliers, customers, ecosystem partners (e.g., third-party service providers), academic entities, and policy stakeholders that often share key human, physical, and knowledge assets with firms. Such organizations exist both in local and global environments. Furthermore, inter-organizational operations (IOO) encompass not only physical, informational, and financial flows but also the movement of talent (people), ideas and knowledge, and legal rights (e.g., franchises), among other things. These flows often occur outside the conventional supplier-customer relationships, such as those involving universities, consulting firms, and other professional service or knowledge providers. In many instances, relationships among these various entities can be little more than arms-length and transactional, if they formally exist at all (i.e., in some cases, firms merely exist in a shared ecosystem). In contrast, in other instances, highly embedded operational co-dependencies are more emblematic. Indeed, operational dynamics are often shaped by both competitive and coopetitive capabilities.

To address this challenge, it is imperative to understand how power impacts justice and sustainability. To this end, we examined a supply network in Mato Grosso, Brazil, that faced power asymmetries through 49 semi-structured interviews, field observations, and archival data. The analysis unveiled three forms of power use—excessive, strategic, and balanced—and associated tactics, impacting justice and sustainability outcomes in various ways. We illustrate, for example, how excessive power manifested in traders' abusive tactics, who compelled farmers to accept quality discounts due to external factors, such as heavy rain or poor road conditions. In response to these injustices, farmers cascaded the pressure through the supply network, disproportionately affecting disadvantaged actors, for instance, by withholding rural workers' wages for low productivity or eradicating wildlife deemed detrimental to profitability.
