Another exciting theory seminar series in Berlin coming up this term: www.wiwi.hu-berlin.de/en/Professor...

In his keynote, Ernst Fehr studies whether people are willing to pay to reduce/increase others' payoff and presents the emerging social preference types. In US data, the predominantly selfish types are the most common (35-40%), whereas Germany has a lot of inequality averse and even envious types!

This is insane: "Elsevier argued that our collective resignation had damaged the journal’s reputation and demanded six-figure damages per person. In the end, it didn’t come to a trial, but the legal uncertainty weighed on me for two years."

I got some bread as complimentary breakfast in my night train to 🇨🇭. I wanted to give it to someone begging in the streets. However, looking at the prices, I am realizing the beggar is me.

How does ambiguity affect trade between a price-setting seller and an ambiguity-sensitive buyer? We find that the right kind of ambiguous information makes both the buyer and seller better off than any possible unambiguous information.

How does competitive pressure fail to protect buyers in information markets? Our new model of "portfolio competition" shows that when signals are complements, sellers leverage the buyer's desire for the joint portfolio to extract the full social surplus.

Why can boosting product quality actually reduce a manufacturer's profits? Our findings show that when retailers control pricing, increasing demand strengthens the retailer's power, compelling manufacturers to give up more profit and optimally limit product quality.

Pre-registration has become mainstream, yet trade-offs persist: Our new survey finds that researchers assign a credibility premium to significant results from pre-registered tests, but a significant proportion expects a negative impact on research creativity and volume.

I will present at the ES Winter Meeting, and I couldn't search and find my name on the program. I was about to message the organizers. The reason I didn't find me is that I went through all theory sessions, but in fact I am presenting in "Experimental Economics II." Still getting used to this...

The song is inspired by a woman the singer met in London in the 80s, and the funniest rumor is that this woman later married the Greek economist and former finance minister Yanis Varoufakis. It's probably not true, but he fueled the rumor himself 🙃
