A new working paper with Daniel Banki, @urisohn.bsky.social and Robert Walatka, just submitted to SSRN. The paper is comment on Ryan Oprea's recent AER paper. The paper is processing, but you, my friends, get early entry. papers.ssrn.com/sol3/papers....

You're probably misunderstanding people's preferences derived from polling results (e.g., 70% of people prefer A over B). In a new paper led by Graham Overton, we discuss this issue and how you can better calibrate your understanding. Short summary: spsp.org/news/charact...

We (i.e., the marketing department at ESADE) are looking for PhD students. Please spread the word:

Another reminder that in a regression with 2 dummy-coded independent variables (X1,X2) and their interaction [Y=b1*X1+b2*X2+b3*X1*X2, where X1(0=group 1,1=group 2), X2(0=group 1, 1=group 2)], b1 and b2 are NOT main effects. They are conditional effects of each variable when the other=0.

Went through JMR's and JCR's latest issues. Not counting qualitative studies and analyses of secondary data, 5 out of 37 (13.5%) studies at JMR were preregistered, while 5 out of 26 (19.2%) studies at JCR were preregistered. Also, no paper wherein all studies were preregistered.

Chocolates are becoming smaller, potato chip bags have more air, and toilet paper rolls are slimming down. We’ve all seen it and we all hate it. Happy to share my new Marketing Science paper on "shrinkflation aversion" with the world. Preprint here: tinyurl.com/shrinkflatio...

Spotted in the wild (JEPG): "Analysis scripts are publicly accessible at (osf link). Data is accessible upon reasonable request. The materials used in this study are widely available." 🤔

Reading the soup bowl study replication. I'm wondering whether the smaller effect size in the replication could partly be attributed to the soup in the replication having more calories per ounce (22 vs 18 in original). If food is heavier, people have lower potential to eat 1/3

JCR retraction: academic.oup.com/jcr/advance-... "The authors state that the hypothesized link between power and consumption deserves future empirical consideration before the field draws any firm conclusions about this relationship." Nope. No future empirical consideration is deserved.

New paper in PNAS (with Anna Paley)! 2 contributions: 1)      People have many more subscriptions than they think they have, and if they know this they intend to cancel some 2)      We use crowdsourcing to generate and evaluate nudges, and find that they performed better than those made by experts

I reviewed a paper with 3 experiments, small samples & not preregistered. I asked for 1 preregistered replication in my review. Authors responded that they didn't run more studies because the paper would become too long. I recommended rejection. Paper is conditionally accepted. Lol

If you were choosing between hotels A (price per night: 79, 3 stars) and B (price per night: 109, 4 stars), would your choice be influenced by adding C (price per night: 109, 3 stars)? Our new paper that answers this question is now free for a limited time at: academic.oup.com/jcr/article/...
