🚨NEW WORKING PAPER🚨
"Preregistration and Credibility of Clinical Trials"
(with Marco Ottaviani)

Pre-approval drug trials preregistered at https://t.co/8OwnlHxrQH appear considerably less p-hacked than non-preregistered trials. 💊💉📝

How do humans interact with pricing algorithms within firms❓

We explore this question using two large-scale field experiments in collaboration with @ZalandoTech in a new WP.

This work is a collaboration with Tobias Huelden, @VJascisens and @LarsRoemheld.

@jdmichler For now our analysis considers only interventional trials as for these it's much clearer how to think about the concept of preregistration. But would definitely be interesting to see which kind of observational studies register and if there timing has an impact on p-hacking, too.

@jt_kerwin The trial data is publicly available and we used it in a previous publication. A preregistration would just have been cheap talk and could not have proven that we didn't see the data before setting up the analysis (unlike for experimental studies where new data is collected).

@julian_schaerer Thanks, Julian!

@florianederer Do you like this one, too? 😏

Here is a 🧵for those of you who are brave enough for a bit of game theory fun. (1/11)

[Christian Decker @chris_de92]

This sounds somehow familiar to you? Indeed, these patterns are remarkably similar to the seminal @ArielRubinstein -Ståhl sequential bargaining game taught often in intro micro classes. (11/11)

[Christian Decker @chris_de92]

In the infinite-horizon version of the game with no restrictions on the length of the debate, there is an unambiguous first-proposal advantage. (10/11)
