Looking forward to this seminar. Such an honor to be in a line -up with so many researchers I admire. I'll be talking about my field experiment on consumer inertia and why attention isn't enough to overcome it!

Denmark is best in EU in getting workers back into jobs (twice the average rate). They also do tons of RCTs to find out what works and apply behavior science. Can’t say it’s causal, but it’s an interesting correlation at least.

I have been thinking whether I can somehow include it in my fall class, but its a bit far off topic for that one. But I‘ll recommend it to others and my students in general. I shared it on LinkedIn a while back as well to counter the hype.

Thanks, that one indeed looks good. But also here it’s more a lab in the field experiment with clearly defined tasks. It is not obvious that the productivity gains will translate to real legal work and thus markedly increase productivity. But it’s a good step.

Only one year after replacing their customer service and marketing team with AI agents, Klarna is regretting the decision and trying to re-hire workers. The quality was just too low to justify the cost-savings. So looks like AI isn't taking your job, just yet. futurism.com/klarna-opena...

This also raises some questions about PhD supervision and data protection at MIT - some supervisor would have needed to sign a data sharing agreement and a secure server would have been needed for the data. That’s a lot of paperwork.

I think the study is interesting, but the total time of the study was 5 hours, the tasks were carefully chosen, and the consultants who participated selected. I think there is no doubt that AI can speed up coding or writing, but I haven't seen much on how that impacts firm productivity.

Christina Gravert @cgravert.bsky.social · 16/05/2025
And harm to the companies using results like this to spend billions on tools that don't work. So far there is very little evidence that AI tools increase productivity for complex tasks. This fake study was one of the only ones.

Nobody likes to feel ashamed all the time, so if we want to encourage more sustainable behavior we 1) need to be careful with moral appeals, and 2) make sure to target behaviors that really make a difference. Thanks, Mette Guldagger at @politiken.dk for interviewing me for this article

Those who can best evaluate their peers also stand in direct competition to these peers - that creates incentives for dishonesty. Nevertheless, these institutions are prevalent in science and arts. Why do they work? We show this theoretically using psych game theory and an experiment.

Norway: 95% of new cars sold in February were electric. But for Tesla, formerly most popular EV, sales were HALVED compared to Feb 2024. Not due to lower total sales: So far in 2025, 46% increase in total sales of new cars compared to Jan-Feb 2024. www.aftenposten.no/okonomi/i/Gy...

Tesla har lenge vært en salgssuksess. Men i februar var salget av nye Tesla halvert sammenlignet med samme måned i fjor.
