To date, these repeated interactions enabling continuity of care have not been studied in hospital inpatient settings. During a hospital stay, decisions related to patient treatment are usually made by two key decision-makers: the attending physician (AP) and the operating physician (OP). Under the single decision-making approach (S-DMA), the AP and OP are the same; in contrast, under the dual decision-making approach (D-DMA), the AP and OP are different. In recent years, there has been an increasing trend toward the use of D-DMA over S-DMA across U.S. hospitals owing to scheduling conflicts. Although research outside healthcare operations management has argued for benefits from both approaches, their impacts on a patient's hospital stay are unclear. In this study, we address this gap by investigating the effects of S-DMA and D-DMA on patient care outcomes in terms of patient length of stay (LOS), treatment cost, and mortality. Data for our study come from the state of Florida and involve 520,554 cardiology patients treated by 9483 APs and 18,398 OPs at 241 hospitals between 2014 and 2016. We account for both patient and physician selection issues when choosing a particular decision-making strategy. Our results suggest that, on average, using S-DMA is associated with reduced patient LOS and treatment cost but has no effect on mortality. We also find that S-DMA is more beneficial for patients with low comorbidity and low process uncertainty, whereas D-DMA is more beneficial for patients with high comorbidity and high process uncertainty. Our results are robust to alternative explanations. We demonstrate that a single decision-maker offers benefits in the context of healthcare delivery, but dual decision-makers may yield benefits when caring for patients with high comorbidity and high process complexity. We discuss the implications of these findings for appropriately deploying S-DMA and D-DMA in inpatient services.</p>","PeriodicalId":51097,"journal":{"name":"Journal of Operations Management","volume":"71 1","pages":"11-39"},"PeriodicalIF":6.5,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143424189","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}

Despite their widespread appeal, these platforms face two critical challenges (i.e., order batching and demand allocation) in effectively managing the delivery process while maintaining reliability. In response, this study aims to address these two challenges by examining the effects of real-time demands and restaurant density on delivery reliability, as well as how the type of driver (i.e., in-house versus crowdsourced drivers) moderates these effects. We evaluated our model with a unique dataset obtained from one of the top three on-demand meal delivery platforms in China, and our research sheds light on several key findings. Specifically, our study finds inverted U-shaped relationships between real-time demands and delivery reliability and a positive relationship between restaurant density and delivery reliability. In addition, it reveals that crowdsourced drivers perform better than in-house drivers under high real-time demands. This study contributes to the literature by clarifying how delivery reliability can be influenced by real-time demands and restaurant density.

Addressing lingering concerns voiced by the editorial team and learning from the experiences of journals from other disciplines that implemented Registered Reports, we introduce a new initiative and outline a new review process in the &lt;i&gt;Journal of Operations Management&lt;/i&gt; (&lt;span&gt;&lt;/span&gt;&lt;math&gt;\u0000 &lt;mrow&gt;\u0000 &lt;mi&gt;JOM&lt;/mi&gt;\u0000 &lt;/mrow&gt;&lt;/math&gt;) to motivate theory-focused field experiments in OM.&lt;/p&gt;&lt;p&gt;Empirical research in OM strives to uphold two key virtues: providing managerially relevant insights and making meaningful theoretical contributions. Field experiments&lt;sup&gt;1&lt;/sup&gt;—testing treatments in controlled digital and physical field settings—tend to possess the managerial relevance virtue because of their strong engagement with key stakeholders and the practical problems that they face. By contrast, the theoretical contributions of a field experiment depend on the extent to which its insights enrich our causal understanding of real-world phenomena. Critically, the degree to which scientific research based on field experiments in OM can be distinguished from consulting engagements and industrial experiments depends on the extent of its contributions to theory. Indeed, there are many different ways of contributing and forms of contribution to OM theory; however, they all serve a common purpose: to build a &lt;i&gt;causal&lt;/i&gt; understanding of relevant OM phenomena. Field experiments can most decisively establish this causal understanding in the complexity of real-world operations (Ibanez &amp; Staats, &lt;span&gt;2019&lt;/span&gt;). Thus, OM research that tests &lt;i&gt;theoretically&lt;/i&gt; motivated treatments in field settings and provides sufficiently deep causal explanations for the observed effects, while also opening a door for future inquiry, possesses both virtues of empirical research. Consequently, we believe that the field of OM can benefit significantly from such research.&lt;/p&gt;&lt;p&gt;Despite the fact that empirical research employing field experiments as the main methodological approach is on the rise in OM, it has traditionally lagged other disciplines such as economics, marketing, and information systems (Gao et al., &lt;span&gt;2023&lt;/span&gt;). For example, Simester (&lt;span&gt;2017&lt;/span&gt;) reports that 37 field experiments were published in the top five marketing journals between 2010 and 2014, a period in which OM published a total of five field experiments in its top five journals (Gao et al., &lt;span&gt;2023&lt;/span&gt;). Between 2005 and 2021, only 31 research articles with field experiments were published in three top-tier OM journals: &lt;i&gt;JOM&lt;/i&gt;, &lt;i&gt;Manufacturing &amp; Service Operations Management&lt;/i&gt; (&lt;i&gt;MSOM&lt;/i&gt;), and &lt;i&gt;Production and","PeriodicalId":51097,"journal":{"name":"Journal of Operations Management","volume":"70 7","pages":"1042-1047"},"PeriodicalIF":6.5,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/joom.1336","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research has shown there is often an economic benefit of such policies in procurement auctions thanks to lower costs for buyers as incentives are offered to disadvantaged sellers. In this paper, we study one type of preferential procurement auction: the subsidy. Using a set of controlled experiments, we compare actual bidder behavior to what is predicted in equilibrium and find consistent (but overly aggressive) patterns overall. By testing a common bid strategy assumption, we also identify a behavioral framing bias that may trap sellers in these suboptimal strategies. Finally, we compare subsidies to another common discriminatory mechanism—the price preference—and find evidence that buyers interested in increasing the welfare of disadvantaged sellers should use subsidies instead of price preference auctions, thanks to a surprising difference in outcomes between preference types. Due to the wide use of bid preference auctions to support both policy and social aims, our findings have both financial and societal implications.</p>","PeriodicalId":51097,"journal":{"name":"Journal of Operations Management","volume":"70 7","pages":"1126-1154"},"PeriodicalIF":6.5,"publicationDate":"2024-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/joom.1333","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142641941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyze secondary data from buyer, first-tier, and second-tier triads impacted at their upper end by the 2011 Great East Japan Earthquake. By matching buyers in affected triads with similar, largely unaffected firms, we assess post-event performance in relation to triad inventory slack. Results show: (a) inventory slack at the first and second tiers supports buyer performance after the disruption; (b) first-tier inventory slack has a greater impact; (c) buyers with less inventory slack can extract more value from their chains' inventories compared to those with more slack; and (d) first-tier suppliers occupy a pivotal role in bridging the second-tier inventories to the buyer. When competition for the first-tier intensifies, the benefits of having first- and second-tier inventory slack diminish for the buyer. A central contribution of this study is to highlight the importance of resources controlled by chain members with indirect links to the buyer and the bridging role of first-tier suppliers.

We adopt a longitudinal case research design that incorporates causal loop diagramming, to understand the system's responses. We find that learning evolves as crisis events unfold, changing from surface (know-what) to deep (know-why and -how) and at the highest level, it is transcendent. Transcendent learning entails understanding system effects into the future (i.e., beyond the past and present) and in relation to other supply systems (i.e., beyond the UK system). Capabilities to absorb, avoid, and accelerate away from shocks are developed sequentially as learning changes.
