"Can we change travel behaviour with nudging?" recording of my talk at the BeScy Environment event. Thanks for having me and the great conversation with the other speakers: www.youtube.com/watch?v=-iir...

A dream come true to work among this team and help shape sustainable banking and policy! And a novel approach for corporate to assemble such a diverse board: www.societegenerale.com/en/news/pres...

Re-order nudges only work when people make fast decisions. Carbon labels don't work to change choices - neither with fast nor slow decisions. New evidence on when nudges work in our new publication: link.springer.com/article/10.1...

Obvious? Or highly debated? Supermarket offers cause unintentional overbuying and can lead to food waste. via.ritzau.dk/pressemeddel...

How (not) to encourage sustainable travel - on the 1st of July, I will be speaking at a BeScy event together with ​Mike Daniels from The Behavioral Architects and Mike Scott from Cycling UK about the possibilities and limits of behavioral science for changing travel habits lu.ma/28rihhmh

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.

Absolutely loved this mini course to think critically about GenAI! Can only recommend it to anyone!

University of Copenhagen and Zurich are dominating this innovation in field and survey experiments workshop @wzb.bsky.social 😄 so many cool experiments with important policy impact

Day 1 of the Workshop on Cognitive Foundations of Decision Making with presentations by @kaibarron.bsky.social @clarasievert.bsky.social @enhuahu.bsky.social Menglong Guan, Natalie Lee, Paul Grass, Julian Matthes, Luigi Butera, and Benjamin Enke.

Excited to host Benjamin Enke as this year’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.

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

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.

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.

One of the best AI papers on productivity turned out to be made up - so disappointing! I really liked the paper and had it saved as „best paper on AI“. Too good to be true! As much of AI claims to fame. www.msn.com/en-us/money/...

In Helsinki for the workshop on using Nordic microdata to solve environmental problems - exciting to see what’s possible in different countries. Thanks to @ahlviklassi.bsky.social for the invite!

Nudging in Romania! I was interviewed by Cătălin Blaga for a local news website and their rethink your brain series. Interview is in English though - an AI avatar could have probably dubbed me 😀 gpinews.live/2025/04/19/d...

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

Associate Professor in Applied Economics – DTU Management #Econsky

Giving a seminar at @uniinnsbruck.bsky.social today - after a morning swim with view of the mountains and econ department and awesome vegan pizza last night. I’ll invite myself again some time 😜

Shopamok og sort menu: Derfor taber økonomisk politik og grøn samvittighed - min forskning om bæredygtig adfærd og økonomiske politikker: www.youtube.com/watch?v=SNL3...

My field experiment students mentioned today in the evaluation how much they would like a comprehensive book. Glennester and Takavarasha is good and we use it currently, but too focused on development economics for my course. Glad this will come in time for next year's course!

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.

And maybe for US academics to return home from conferences on topics such as climate change, inequality and human rights.

Dear academic economists! Two weeks left to apply to a position as full professor at the Econ Dept @stockholm-uni.bsky.social. in Sweden, academic - and personal - freedoms are deeply respected. And the microdata is awesome! Deadline March 31! #econsky su.varbi.com/en/what:job/...

Welcome to Copenhagen @manuelmenkhoff.bsky.social !

Talking about behavior change at today’s conference on sustainable behavior in banking and finance at the law faculty at University of Copenhagen.

Didn’t think Trump would be pushing his followers to buy electric cars, but here we are 😄 Together with everyone else buying electric from other brands this should be a win.

📣 Thrilled to announce our 4th Workshop on Field Experiments in Economics and Business, 8-9 Sept 2025, TU Munich @tum.de, Campus Heilbronn. Keynotes: Ulrike Malmendier (University of Berkely, California) & Noam Yuchtman (@ox.ac.uk) 🫶🏻 Submission deadline 15 May 🚨 #EconSky

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...

🚨Predoc Position in Economics at the University of Bonn Are you interested in joining my research team as a full-time predoc? In my research, I aim to identify policies that advance gender equality, improve children's outcomes, or promote climate action. sites.google.com/site/bonevat...

Some of the major Danish supermarkets have introduced a star symbol to show which products are made by European-owned companies (to boycott American companies). We know climate labels don't work, but would love to see if there is an effect of these stars on consumption patterns.

Dean Karlan's job at USAID was LITERALLY to improve the efficiency of its programs. DOGE is clearly not actually after cutting fraud and waste. And its actions will clearly make the US weaker while also making the world a worse place. www.npr.org/sections/goa...

We just released our paper using a field experiment to reveal indoor air pollution (IAP) in London: It’s worse than you think! 🧵with six main results👇 With @sjroth.bsky.social.

Ich bin schon so gespannt auf die Promotion, die er während seiner Elternzeit schreibt: "Die rechtliche Einordnung der Imkerei im Familienkontext: Analyse der Vereinbarkeit von Bienenhaltung und Elternschaft"

Most romantic Valentine’s Day activity - brunch and then voting together in the German National election! 5* can recommend 😄

Elon Musk getting access to all that personal information is scary, right? In a few years quantum computers can crack all current encryption methods. What can we do about it? Find out by inviting @cryptocarsten.bsky.social to talk about it as part of Book a Forsker festival forsk.dk/indbakke/can...

Den 3. marts skal jeg holde offentlig foredrag om min forskning hos Videnskabernes Selskab (Danish Royal Academy of Science) Time to practice my Danish 😅https://royalacademy.dk/event/shopamok-og-sort-menu-derfor-taber-oekonomisk-politik-og-groen-samvittighed/

How cool is this?! A behind the scenes seminar series on how an economics paper came about - all the invisible work that never gets into the printed version. First event on 17th of February. I am also looking forward to using the recordings for teaching. www.bts-seminar.net

Looks like the US government wants to move back to the time when (mostly) women had to publish under pseudonyms or through their male colleagues for their work to be seen. Then again, what will they publish without data or funding...?

📢We are looking for a new #PhD colleague📚📢 Open call for a 3-year PhD on the #green #transition and #sustainability at the #CBS Sustainability Center. #behavioralscience applications are very welcome! @drtanusreejain.bsky.social | @katharinehayhoe.com | @jakereynolds.bsky.social

So any NSF funded behavioral science research is on the list… and most standard economics research.
