Crowding and service process stages moderate this effect. In less-crowded settings, customers show higher ownership toward human-delivered services.

While technological capabilities enable hotels to sense and respond to new technologies, the cognitive mechanisms through which managers translate these capabilities into innovations remain underexplored. Drawing upon stakeholder theory, information processing theory, and prospect theory, we examine how hotel managers' interpretations of customer feedback strengthen the conversion of technological capabilities into both incremental and radical digital innovations. Using data from 197 Brazilian hotels collected during March-April 2023, we employed PLS-SEM to test our hypotheses. Results reveal that managers' perceptions of online hotel reviews significantly strengthen the relationship between technological opportunism and both types of digital innovation. We demonstrate asymmetric effects whereby managers' perceptions of negative reviews create significantly stronger moderating effects than positive reviews for both innovation types, confirming loss aversion principles in organizational innovation decisions. Both innovation types positively influence financial performance, with incremental innovations showing stronger immediate effects than radical innovations. This study advances stakeholder theory by demonstrating how customer-generated digital content influences strategic innovation decisions through managerial attention mechanisms. It extends information processing theory by revealing cognitive amplification effects of customer feedback on technological capabilities and contributes to prospect theory by confirming loss aversion principles in organizational innovation decisions. Our findings provide evidence-based guidance for hotel managers, suggesting systematic integration of customer feedback analysis into innovation processes, with particular attention to negative reviews and balanced innovation portfolios that emphasize incremental improvements while pursuing radical transformations.</div></div>","PeriodicalId":48444,"journal":{"name":"International Journal of Hospitality Management","volume":"133 ","pages":"Article 104416"},"PeriodicalIF":8.3,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145027234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a few of the latest research has provided mixed findings on the effects of house rule design on guests’ responses. Utilizing signaling theory as a foundation and exploring the nonlinear effects of house rule depth, this research aims to reconcile the mixed evidence indicating a trade-off situation in hosts’ house rule design practices. The authors hypothesize that two underlying mechanisms exert opposite effects: moderate house rule depth has positive effects on guests’ booking behavior as it signals both fitting perception of house quality and high service expectation of host, while low or high house rule depth shows negative effects as it signals either uncertainty of house quality or unfriendliness perception of host. Further, the current research also examines moderating effects of price and the “Superhost” badge, which represents additional critical signals of house quality and host. These insights contribute to a nuanced understanding of balancing house rule design in P2P accommodations and offer practical implications for both hosts and platforms to optimize their booking rates.</div></div>","PeriodicalId":48444,"journal":{"name":"International Journal of Hospitality Management","volume":"133 ","pages":"Article 104422"},"PeriodicalIF":8.3,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145049761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
