## Publications

- [Pre-Registered Interim Analysis Designs (PRIADs): Increasing the Cost-Effectiveness of Hypothesis Testing (2024)](https://quentinandre.net/publications/priad/priad.md): Journal of Consumer Research. We show that group sequential designs (which allow to perform interim analyses while data collection is ongoing) can unlock numerous benefits for researchers engaged in confirmatory hypothesis testing: They facilitate sample size decisions, allow researchers to achieve a desired level of statistical power with a sma… DOI: 10.1093/jcr/ucae028.
- [Probabilistic Outcomes Are Valued Less in Expectation, Even Conditional on Their Realization (2023)](https://quentinandre.net/publications/probabilistic-outcomes/probabilistic-outcomes.md): Management Science. Would people report a different valuation for a 50 dollars Amazon gift card that is certain to be available, and for the same gift card that has a 10% chance of being available? In violation of expected utility theory, we show that people anticipate less utility from uncertain outcomes than from certain outcomes, ev…
- [Outlier Exclusion Procedures Must be Blind to the Researcher's Hypothesis (2021)](https://quentinandre.net/publications/outliers-blind-hypothesis/outliers-blind-hypothesis.md): Journal of Experimental Psychology: General. How should researchers exclude outliers: Across the data, or within conditions? In this paper, I show that when outlier exclusions are performed in a way that is not 'blind' to the researchers' hypothesis (e.g., within conditions), they increase Type I error to unacceptable levels. DOI: 10.1037/xge0001069.
- [Can Consumers Learn Price Dispersion? Evidence for Dispersion Spillover across Categories (2021)](https://quentinandre.net/publications/dispersion-spillover/dispersion-spillover.md): Journal of Consumer Research. Should I search for a cheaper flight? How much should I bid for the house? To answer those questions, consumers form beliefs about the dispersion of flight prices or house bids... but how accurate are those beliefs? We provide evidence for a phenomenon we call dispersion spillover: Seeing more (vs. less) dispersed p… DOI: 10.1093/jcr/ucab030.
- [No Evidence for Loss Aversion Disappearance and Reversal in Walasek and Stewart (2015) (2020)](https://quentinandre.net/publications/reanalysis-ws/reanalysis-ws.md): Journal of Experimental Psychology: General. Can loss aversion disappear and reverse? In this article, we show that the shifts in loss aversion reported in Walasek and Stewart (2015) are driven by an invalid experimental paradigm. After correcting this error, we do not see evidence that loss aversion is shaped by the distribution of gains and losses that peopl… DOI: 10.1037/xge0001052.
- [Healthy through Presence or Absence, Nature or Science? A Framework for Understanding Front-of-Package Food Claims (2019)](https://quentinandre.net/publications/fop-claims/fop-claims.md): Journal of Public Policy & Marketing. Consumers intuitively categorize front-of-packaging claims displayed on food into 4 broad categories: (1) Claims about “removing negatives,” (2) claims about “adding positives,” (3) claims about “not adding negatives,” and (4) claims about “not removing positives.” Each type of claim is associated with different bel… DOI: 10.1177/0743915618824332.
- [Consumer Choice and Autonomy in the Age of Artificial Intelligence and Big Data (2017)](https://quentinandre.net/publications/choice-autonomy-ai/choice-autonomy-ai.md): Customer Needs and Solution. In this summary of a Choice Symposium session, we explore the opportunities and challenges that the development of automation and artificial intelligence pose to consumers. They can, on the one hand, contribute to consumer well-being by making choices easier, more practical, and more efficient. On the other hand, th… DOI: 10.1007/s40547-017-0085-8.
