#Econsky That was a great workshop on Political Economy at @ox.ac.uk - @nuffieldcollege.bsky.social, jointly organized with @iast.fr - @tse-fr.eu and @sciencespo.bsky.social No cheaptalking, the quality was high! Grateful for this life/scientific event 🙏🏼

We definitely need to understand better the climate gouvernance framework. Thanks!
Here is our take: we show that climate regulation may also spurr civil society activisme (NGO campaings against firms): hal.science/hal-05047276v3

Another successful scientific event at @cerdi.bsky.social. A place to be for economists 🙌🏼📈🔥

What happened when the U.S. forcibly sent 400,000 Mexican workers back to Mexico in the 1930s?

The employment rate of native workers *went down* noticeably as a direct result. (You read that correctly)
