Photo credit goes to my favorite young artist — my nephew — whose rocket drawing has hung proudly in my office for years. Felt only right to bring it along for this new launch. 🚀

To everyone at @humboldtuni.bsky.social and the @rationalitycrc.bsky.social – thank you for shaping my academic journey in ways I’ll carry with me for years to come.

To my future colleagues at NEOMA: I can’t wait to get started!

Also a huge thank you to the CRC’s spokesperson and deputy spokesperson, @klaus-m-schmidt.bsky.social and @georgweizsaecker.bsky.social, for creating such a vibrant research community.

It’s also been an incredible privilege to be part of @rationalitycrc.bsky.social and its sub-project A05 on information transparency and consumer choice. Huge thanks to co-PIs Daniel Klapper, Martin Spann, and @dhguhl.bsky.social.

I owe a great deal of gratitude to Daniel Klapper, my PhD advisor, to Lutz Hildebrandt, my PhD grand-advisor, for their unwavering support and guidance; and to @dhguhl.bsky.social – exceptional mentor, co-author, and partner-in-crime in the search for the best coffee, spicy sauce, and memes.

It’s a rather bittersweet goodbye to @humboldtuni.bsky.social, my academic home for over a decade (OMG) – from Master’s student to PhD to postdoc. I’ve been incredibly fortunate to work and grow in such a collaborative and intellectually generous environment.

More to come soon — stay tuned 💬📊

Thanks to the amazing EMAC community for the inspiring conversations and the organizers for a great conference! #MarketingSky

Findings:
More attributes = more selective consumers.
More alternatives? Non-linear impact—consideration initially rises, then plateaus (well below full attribute consideration).
When things get too complex and involvement is low, people turn to extrinsic cues over intrinsic product attributes.

2️⃣ Meanwhile—literally simultaneously 😂—Alaa Elgayar was presenting our second paper.

We look at how choice complexity & product involvement shape consumers’ tendency to ignore product attribute information.

1️⃣ Ever canceled a reservation or just didn’t show up?
In industries with limited capacity, these pose a serious challenge. Together with @nemipuka.bsky.social, we study how no-show & late cancel fees on a multi-sport subscription platform shape booking behavior, attendance & churn.

I was expecting to guess at least 2 out of 5, but I ended up with 0. I completely forgot what I was listening to on repeat (and how much) during the first half of the year.

Preferences are indeed heterogenous. :) my personal favorite is Paterson. To be fair though, we can't really judge whether he is making good choices or not as we don't know what roles he is being offered and on what conditions.
