Item type:Publication, DICE: Advancing Social Media Research through Digital In-Context ExperimentsThis article introduces Digital In-Context Experiments (DICE), an experimental paradigm that enables researchers to study entire social media feeds while tracking users’ granular behavioral data at the post level. Current research paradigms (vignette-based experiments, online platform studies, and observational studies) predominantly focus on isolated social media posts without examining how users consume content within the broader context of a feed. This isolation overlooks the competing attention between content (e.g., sponsored posts or ads) within a feed and contextual spillovers that occur when users scroll through continuous streams of content. DICE complements existing paradigms by presenting posts within scrollable feeds, more closely resembling how users experience content on social media. This allows researchers to systematically manipulate entire feed compositions while unobtrusively tracking participants’ scrolling behavior. To demonstrate the potential of DICE, the article presents two illustrative case studies that examine contextual spillovers and predict ad recall in environments where content competes for attention. The authors conclude with directions for future research and managerial perspectives derived from expert interviews with marketing professionals. An accompanying open-source app, available at https://dice-app.org, enables researchers to conveniently integrate the experimental paradigm into their preferred workflow.Type:journal articleJournal:Journal of MarketingScopus© Citations 5 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Ambiguity attitudes and surprises: Experimental evidence on communicating new information within a large population sampleThis paper investigates ambiguity attitudes for natural events (temperatures) and how they are updated following new information. Using a general population sample, we first obtain baseline ambiguity attitudes for future weather events based on real temperatures over several past days. Second, we study the influence of different communication types on updating the ambiguity attitudes: participants are given either point estimators, interval estimators, or the combination of both as weather forecasts. We further vary whether the forecast is surprising or in line with the initially received information. In contrast to claims that ambiguity aversion may increase in response to surprising news, we find that ambiguity attitudes are rather robust to new information and variants of their communication. Yet, different variants of communicating new information significantly change the belief updating process and affect the matching probabilities given to specific events. Our sample allows us to analyze socio-demographic correlates of ambiguity attitudes and the updating of ambiguity attitudes to new information.Type:journal articleJournal:Journal of Economic Behavior & OrganizationVolume:228Scopus© Citations 3 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Using Voice Data to Measure and Predict Consumer Preferences(2025-10); ; Jiang, ZhenlingWhen consumers use voice-enabled technologies, they convey more than their choices—they reveal paralinguistic cues. Across four studies, we demonstrate that certain vocal cues are closely linked to preference strength, enabling reliable predictions. We discuss the implications of our findings in an increasingly voice-first digital landscape.Type:conference contribution - Some of the metrics are blocked by yourconsent settings
