🚨 New version of our WP 🚨 (w/ Michela Limardi & @avolle.bsky.social). 🔎 Climate regulation doesn’t crowd out NGOs—it mobilizes them. Activism rises & persists, esp. in weaker enforcement contexts. Grateful to @cerdi.bsky.social colleagues for seminar feedback 🙏 🔗 hal.science/hal-05047276v4

🚨 New version of our WP! 🚨 @sophiehatte.bsky.social (@cergic.bsky.social), @ttaylor-econ.bsky.social (@eui-eu.bsky.social) and I (@cerdi.bsky.social) highlight the powerful role of digital access in shaping democratic outcomes and promoting gender equality. 📄 Link: papers.ssrn.com/sol3/papers....

#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 🙏🏼

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

📣 New WP in #economics 📄 “Climate Regulation & Civil Society Activism” By M. Limardi, @jordanloper.bsky.social & @avolle.bsky.social 🏷️ Evidence from 75 countries (2010–2022) shows that public #climateregulation amplifies #activism rather than crowding it out. 👉 t.ly/c-f1d #Research #NGOs

We have a new DP. It's actually more a tool than a paper. The Robustness Dashboard provides an at-a-glance visual summary of robustness analysis, distinguishing between confirmatory and negative robustness tests. @i4replication.bsky.social 1/3 www.econstor.eu/bitstream/10...

Will different researchers converge on similar findings when analyzing the same data?[...] scientists, especially those working with the complexities of human societies and behavior, should exercise humility and strive to better account for the uncertainty in their work.

The past really sticks. Even after 4 generations, your great-grandfather’s economic status still largely shapes your own. 👉 33% persistence across time for whites 👉 But racial inequality is the key driver The American Dream? More inherited than we thought. www.nber.org/papers/w33923

Thanks! It started by chatting with Anke 15y ago (!) on how governments may negotiate treaties not because of spillovers, but to tie hands of future governments => (a) coalitions can be larger (b) we provide a unique theory of "conventions" (c) the Paris Agreement won't unravel even if US withdraws🙂

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) Why? Forced repatriation destroyed low-skill markets. www.sciencedirect.com/science/arti...

The longer I spend in academia, the deeper is my belief that opportunity hoarding by elites is real and so much worse than normal folks realize.

Every persistence study be like…

Two blog posts for you. One more recent by @olihanney.bsky.social here: voxdev.org/topic/import...

🚨 #EconSky Updated WP 🚨 First empirical evidence that public environmental regulation can stimulate climate activism from civil society. This finding highlights an often-overlooked indirect effect of regulation in the fight against climate change. 📄 Paper link: drive.google.com/file/d/1TIzN...

Three things made the US a rich and powerful nation: the rule of law, its science & innovation system, and openness to foreign talent. Remarkable how Trump has taken a sledgehammer to all three. No enemy of this country could do more.

A long long time ago, in a far away galaxy... the US used to tax the rich

Cultural homophily is persistent, pervasive, and consequential, even in superstar multinational teams of high-skill people with common objectives, doing well defined, interactive, not particularly culture intensive tasks. pubsonline.informs.org/doi/abs/10.1... Oh, we use football data. #EconSky

Indeed, my experience is a very low level of engagement, despite posting mostly academic stuff to an academic audience

Update: We submitted the comment to the Journal of Population Economics, and today we got a desk reject with this motivation. However, we do not know their conclusion about the main results and why the paper was not retracted. Clearly, they do not hold. 1/4

"We find some evidence that published papers with greater connectivity subsequently receive fewer citations." In short, the publication game is a bit of a rigged game. At least at one particular journal. www.journals.uchicago.edu/doi/10.1086/...

Just admitted to our political economy students that our rational choice and utility maximizing models have little explanatory power these days.

30 years after arriving in the US, I just resigned from Northwestern and we sold our house. We are an American family, I became a citizen in 2014, and until recently did not expect to ever leave. But now, this no longer feels like the right place to raise a family and pursue a research career.

🚨 #EconSky 📈📉📊 Check out our last @voxeu.org Column ! 🚨

📖 Today, I received a signed copy of a book from Jean-Paul Azam, my former professor at @tse-fr.eu — a mentor who not only taught economics 📊, but also embodied what it means to be a free mind 🧠✨. This gesture is a quiet passing of the torch 🔥. To my professor: thank you 🙏. @cerdi.bsky.social

to be honest the other 2 are: various health / wellness / well-roundedness reasons, and my sense that our real contributions to science and scholarship are our 2-3 best papers and our advising/teaching, to me it makes more sense to try to do less but better

even with this attitude, of course at times my papers have been sloppy and had errors, failures to cite, etc. but i know we tried hard and we corrected when pulled up short. been clear to me for a while that others who are working faster and doing more are often or even typically much sloppier.

Maybe journals should have a policy that data from anonymous sources will be verified by the journal before publication. The editor could contact the firm, to verify that it exists and that the study was conducted as stated. @aeadata.bsky.social is this feasible or am I missing something?

For the record, it’s for this same reason that I turned down several chances to work on papers about Covid during covid, and recommended instead that people coauthor with bio stats / epi people

Be careful with self-selection of immigrants when studying cultural persistence/assimilation. We also have a paper on this in the Journal of Development Economics: www.sciencedirect.com/science/arti...

Moving people to places with jobs might help those people but it hurts the people and communities left behind, @timbartik.bsky.social says. "You have to address the fact that people have attachment to places ... If you don't recognize that, you can't do policies that are adapted to people's needs."

I am very pleased to share this announcement of our new center at MIT. @davidautor.bsky.social, @simonhrjohnson.bsky.social and I are grateful to the Stone Foundation for their generous support enabling us to study two defining challenges of our age: inequality and the future of work.

After one year of waiting, we finally got a response from the Journal of Population Economics about our replication of "Banning the purchase of sex increases cases of rape: evidence from Sweden", confirming the major coding error that invalidates the main results, but not retracting the paper. 1/2
