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. Canโ€™t say itโ€™s causal, but itโ€™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 Iโ€˜ll recommend it to others and my students in general. I shared it on LinkedIn a while back as well to counter the hype.

I still have one of your โ€žbullshitโ€œ talks (from 2021) as a homework assignment for my students and have them choose their favorite bullshit examples and then we discuss them in class. I am a big fan of you work and LOVE the new AI course. Thanks for providing these resources!

Excited to host Benjamin Enke as this yearโ€™s Zeuthen lecturer the University of Copenhagen. The lectures run over three days and are complemented by a workshop on the cognitive foundations of decision making.

In-store food promotions increase sales as well as household food waste Scientific Reports - In-store food promotions increase sales as well as household food waste

Our publication on how multi-buy offers increase unplanned overbuying and how this can increase food waste at home is out and open-access! This was probably one of the most complicated field experiments I ever ran, but also one I am very proud of: rdcu.be/enmFi

Thanks, that one indeed looks good. But also here itโ€™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 itโ€™s a good step.

Company Regrets Replacing All Those Pesky Human Workers With AI, Just Wants Its Humans Back Years after outsourcing marketing and customer service gigs to AI, the Swedish company Klarna is looking to hire its humans back.

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. Thatโ€™s a lot of paperwork.

The retracted study showed impacts on patents filed - something that would really matter for a firm's bottom line. A new Danish study also shows no effects on labor market outcomes www.nber.org/papers/w33777

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.

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.
