Ich habe mich sehr gefreut, einen Gastbeitrag für die Rubrik "Der Volkswirt" in der @FAZ_Wirtschaft schreiben zu dürfen. Zu lesen gibt es ihn auf Seite 16 der gestrigen Print-Ausgabe und online unter faz.net/aktuell/wirtschaft/o…
5x⭐-Bewertungen sind online heute die Norm. Überraschend: Das Phänomen verstärkt sich mit der Zeit, obwohl die Qualität der Produkte nicht besser geworden ist. Warum? Das erklärt #ZEW-Ökonomin @JanssenReb im @FAZ_Wirtschaft-Gastbeitrag.

Very excited about this joint work with @JanssenReb . We all know that leaving anything less than a five-star review for an Uber means a red flag. But how does this ‘review inflation’ translate to other online platforms? Are all users equally susceptible?
The amount of ⭐ in online shop reviews has seen an upward trend, with an unchanged product quality, shows a study by #ZEW economist @JanssenReb: online review systems may fail to fulfill their function of providing new customers with helpful reports. 👉 zew.de/PM8918-1/?twt=1

Please share widely: I'm seeking to hire a postdoc (100%) at @heclausanne. Other than the beautiful nature in Switzerland, there are no distractions. You can fully concentrate on research 🚀

I can only highly recommend this event. It is great to meet other PhD students from the field and @avicgoldfarb and @ce_tucker are great organizers, connecting junior with senior economists.
Unfortunately, I can't attend this time in terms of time.
Please share this application for the October NBER
privacy and econ tutorial with your PhD students. They don't need to submit a paper - just a short application.

Colleagues and I have a new paper on GDPR whose abstract has prompted a little Twitter heat. I’ll add my perspective, consisting mostly of cool water. 1/n

Statement der @EFI_Kommission - #Coronakrise macht Vorteile & Chancen der #Digitalisierung für öffentliche #Verwaltung #Hochschulen & #Wirtschaft noch deutlicher. Die Chancen sollten jetzt genutzt werden! @BMBF_Bund @BMWi_Econ @DoroBaer @LeibnizWGL
Corona-Krise macht deutsche Digitalisierungsdefizite sichtbar.
EFI aber optimistisch: Aktuelle Einschränkungen können der Digitalisierung in Deutschland einen Schub geben

This week I did my first virtual seminar. It was a great experience. Hats off to the organizers! And it got me thinking about digitization and the IO of seminars. So: a thread .
