This new QJE paper concludes that the macroeconomic costs of climate change are far greater than earlier estimates suggested. It finds that a 1°C rise in global temperatures reduces world GDP by over 20%.
I am looking for a PhD student in energy economics starting in the fall, focusing on household-level energy use and energy poverty.

Após mais de 2.558 dias do rompimento da barragem da Vale em Brumadinho, que matou 272 pessoas, o Corpo de Bombeiros de Minas Gerais encerrou as buscas pelas vítimas. Sete anos depois, a maior parte da lama tóxica permanece no ambiente e ninguém foi julgado pelo desastre.

Der Belém-Spruch von Friedrich Merz war herablassend und billig, und sagt mehr über ihn aus als Belém. Damit schädigt Merz nicht nur dem Ansehen Deutschlands, sondern auch den Bemühungen bei der Weltklimakonferenz. 🇧🇷 #Merz #Belém www.spiegel.de/wissenschaft...

The aggressive immigration raids we now see across the nation began 10 months ago in California's Central Valley. Their impact on children, families, and communities is an important & active area of research
I'm pleased my study of the initial raid's early impact on students is now out in @pnas.org
Hmm, I also don't know what it means, but I know how to make your kids stop using it at home, fellow parents. Adopt it and let it slip casually into conversations with your kids.😉 www.theguardian.com/education/20...
It might be hard to convey to people outside economics just how seismic this is. The Trump effect has most certainly arrived to US academia.
Real change in public expenditures on higher education, 2008 to 2023, selected countries that actually publish the damn data. UK is worst here, but note this does not include RAB (projected future loan forgiveness, basically). If RAB is included...UK would still be last.
My opinion about the historic verdict coming out of Brazil, with @stevelevitsky.bsky.social, is in the @nytimes.com today.

Congrats Nadine, very important and timely work!
A big thank-you to my colleagues at FJP for their outstanding work in organizing this series and driving the conversation on using evidence to shape better public policies
This lecture marked the kick-off of a series of events on evidence-informed policymaking, funded by the British Academy and developed in partnership with the João Pinheiro Foundation.

Yesterday, I had the privilege of delivering a lecture to the State Minister of Planning of Minas Gerais, Brazil. We discussed key lessons from the UK’s system of policy evaluations and how these insights can help strengthen evaluation practices in Brazil.

Trump does shit every day that should get him impeached. But illegally punishing an entire country — and any Americans who use products or do businesses with anyone in Brazil — because it’s prosecuting its former president for attempting a violent coup is among the worst things he has done.
Using time series graphs to make causal claims be like

I left Ireland and moved to New York in 1997. Decades on, what the US has become has broken my immigrant heart.
It also baffled me, until I began to piece together Gen X memories of apartheid South Africa.
I'd love to fund studies of interventions that reduce real-time pollution exposure, in the US, on outcomes related to violence and criminal behavior.
(There is strong evidence that such exposure increases violence in real time; the next question is how much interventions can mitigate this effect.)
Re-upping my advice about how to write a good title and abstract for an academic paper, appropriately called:
"How to Write a Title and Abstract"
Feel free to share this thread, which will focus on titles.
