Applying these methods in a new <em>meta</em>-analysis of advertising effectiveness, using the largest database on business-to-consumer own-brand advertising elasticities (538 elasticities), the authors show that better methods greatly reduce (more than fivefold) the <em>meta</em>-analytic overall estimate of advertising effectiveness relative to prior estimates, bringing them more in line with results from randomized controlled trials. They first obtain an average short-term elasticity of 0.0008 and a long-term elasticity of 0.03. They then explore how and when conditional advertising elasticity estimates meaningfully differ across relevant factors through advanced multiple <em>meta</em>-regression approaches that yield practically meaningful conditional estimate ranges. Over time, reported <em>meta</em>-analytic estimates of advertising-sales elasticities have become smaller, largely due to improvements in <em>meta</em>-analytic methods, while advertising effectiveness has increased—consistent with the finding that internet advertising, the most recent medium, exhibits the highest elasticity. For advertising scholars and professionals, this study provides an updated (i.e., lower) benchmark on overall advertising effectiveness, as well as more robust insights regarding when and how it varies. For analysts, it charts an improved methodological framework for marketing that should guide <em>meta</em>-analytic research on and beyond advertising effectiveness.</div></div>","PeriodicalId":48298,"journal":{"name":"International Journal of Research in Marketing","volume":"43 1","pages":"Pages 131-151"},"PeriodicalIF":7.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147454275","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 provides a comprehensive guide for implementing GenAI interactions in marketing studies, particularly within the Qualtrics platform. First, a literature review categorizes diverse GenAI applications—from scaling qualitative methods to creating novel experimental paradigms—distinguishing between GenAI as research method versus research object to help researchers identify untapped opportunities. Second, the paper presents a decision framework for when GenAI offers value over traditional methods and explains the principal architecture (frontend, API, backend) that enables researchers to connect any GenAI model to their studies. Crucially, it demonstrates how AI coding assistants can translate natural language instructions into functional code, eliminating programming barriers for non-technical researchers. Third, step-by-step tutorials establish emerging best practices through four implementations spanning text and image modalities: search assistants, automated interviewers, co-creation tools, and hyper-personalized messaging. These implementations serve as adaptable templates empowering researchers to create custom solutions for their unique questions. By mastering AI coding assistants rather than copying specific code, researchers gain methodological independence in a rapidly evolving landscape. This work democratizes GenAI integration and enables previously impossible experimental paradigms.</div></div>","PeriodicalId":48298,"journal":{"name":"International Journal of Research in Marketing","volume":"43 1","pages":"Pages 28-47"},"PeriodicalIF":7.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147454276","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}

Analyzing the complete purchase and return behavior of customers of an online fashion retailer over six years, we show that the average customer’s return rate increases by 48% from their first to their tenth purchase. We investigate how customers’ past behavior explains returns for their current purchase and ultimately return rate evolution. Our results provide evidence for a brand experience effect: A greater number of previously purchased items indicates a decrease in return rates. We also find evidence for a return habit effect: A greater share of previously returned items indicates an increase in return rates. We quantify both effects and show that return habits dominate, resulting in an increase in customer return rates. For managers, understanding the return rates evolution has important implications. If managers at the focal retailer ignored customer return rate evolution, they would overestimate cumulative customer value by about 40% after ten purchases. This evolution poses a particularly acute challenge for retailers operating on slim margins and facing high customer retention costs, potentially transforming profitable customers into financial liabilities.</div></div>","PeriodicalId":48298,"journal":{"name":"International Journal of Research in Marketing","volume":"43 1","pages":"Pages 71-91"},"PeriodicalIF":7.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147454272","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}

Whereas previous research attributes this devaluation to the ugly-is-bad effect, this research identifies an important moderator of consumers’ reliance on this heuristic: the lay theory that a person’s outer appearance reveals their inner character. Specifically, consumers who believe that people’s appearances reveal their character are less willing to accept unattractive (vs. attractive) produce because they generalize their lay theory to produce and are, thus, more likely to infer that unattractive produce is of lower quality. Consumers who do not hold the lay theory do not demonstrate this effect. An intervention emphasizing that produce’s outer appearance does not reflect its inner quality blocks this generalization of the lay theory to produce, thereby increasing acceptance among those who endorse the lay theory. Importantly, the intervention has no negative effect on those who do not hold the lay theory, making it broadly applicable in the field without the need to segment consumers based on their beliefs. Incentive-compatible studies conducted in-person and on Facebook™ show that this intervention is more effective at increasing consumers’ interest in unattractive produce than an intervention directly targeting the ugly-is-bad effect.

Further relying on a set of scenario experiments we demonstrate that playing video games online helps to reduce the feeling of loneliness and leads to stress signal attenuation. To allow game developers to get a better understanding of which elements do help with decreasing stress signals, we further control for contingencies such as video game characteristics. Our granular analysis demonstrates that the stress signal attenuation observed in gamers is closely linked to a game’s capacity to foster social interactions.
