Today I ran the Airborne Freedom Run for Pawel Sobota and all the other (young) people who died for our freedom in WWII.

I will not attend this year but what a nice list of awards for junior researchers and creative work. Should be fun to select the most creative paper, and challening because there is a lot of creativity in this field!

Stated vs. revealed preference. Trump in words: "The data can’t be propaganda. The data has to be something that you can trust." Trump in deeds: www.heritage.org/markets-and-....

It was a great privilege to be one of the humble guides for this journey. It was nice to see you grow into your research, discovering what makes you tick.

Answer:

Which band? Which album? Which city? Tonight they play in Dortmund, Germany.

Today the final day of the Behavioural and Experimental Economics Workshop in Florence. I heard many great talks and am glad to be part of it. Thx to the organizers!

Ik neem aan dat NWO in het hierheen halen van toppers niet meeweegt waar in de VS men nu werkzaam is of in welke bladen men publiceert ... ben benieuwd wat wel de selectiecriteria worden.

For the second time, I have been asked to review a paper with made-up references. I am pretty shocked how many of such papers (and "scientists") apparently are floating around. Who has had similar experiences?

Yesterday, @mvoldeniel.bsky.social defended his excellent dissertation. He did very well and fully deserved the drinks in the evening with (old) friends and family. Thanks to @julianafziger.bsky.social for being part of the committee.

Mooi gitaarspel op Ik ben niet bang! Ik wist niet van deze gepassioneerde hobbyband.

This Christmas, I read Frederic Vermeulens book De heks van Gottem, a captivating (family) story about the witch hunts in the Spanish Netherlands around 1590. Well-researched just like his scientific work, but (unlike Econometrica contributions) also a real page turner. www.lannoo.be/nl/de-heks-v...

Lieke has been the creative mind and driving force in these nice projects with the Innovation Panel. Please send her any comments you have.

We find active exchange and surprisingly little free riding: users return 9 book for every 10 books they take out. Strong social norms and preferences for cooperation among owners and users can explain the observed high and stable level of reciprocal exchange. (4/4)

We answer the question how much use is made of these bookcases by tracking the number and quality of books that people bring in and take out, where we use both second-hand price and reader ratings as indicators of a book’s value/quality. (3/4)

We present unique quantitative data on the book exchange that happens via little free libraries, a low-profile but surprisingly popular and wide-spread way for readers to share and exchange books. (2/4)

Happy to announce that my paper “Sharing with Minimal Regulation? Evidence from Neighborhood Book Exchange” (with Anouk Schippers) has now appeared in Eur. Econ. Review. A fun project to work on. A short thread (1/4)
