"How reliable are national accounts estimates of agricultural output?" Answer: Yikes. Survey data from Mozambique suggests "real rates of total GDP growth may have been overestimated by 1 percentage point" for 2 decades! Signs the problem is not limited to Mozambique.

The curse of reading this Gelman paper is that you then see this absolutely everywhere...

"The old model of aid focused on eradicating poverty had clarity and currency ... Then came the Sustainable Development Goals (SDGs): 17 goals, 169 targets, and a commitment to everything"

Quite the quote.

“Among articles stating that data was available upon request, only 17% shared data upon request.”

🚨 I4R released my experiment with a new academic-literary form, a “replication opinion.” I made myself judge in a debate and wrote an opinion that is more credible than either party could muster. Piece: econstor.eu/handle/10419/3… Post: davidroodman.com/blog/2025/05/0… 🧵 follows

Sad to hear Keir Starmer saying immigration is turning the UK into an “island of strangers”. People who have moved here from other countries are my friends and neighbours, not strangers.

Tragic to hear Keir Starmer say that immigration is turning the UK into "an island of strangers." What a narrow, nasty, pessimistic view of the people of the UK. People who have made the UK their home from around the world include my friends & neighbours & are not strangers.

The step-up in anti-migrant rhetoric from the government is shameful and dangerous. Migrants are our neighbours, friends and family. To suggest that Britain risks becoming “an island of strangers” because of immigration mimics the scaremongering of the far-right.

We did not want to start the week like this, but here we are. Yet again our chair’s inbox is filled with messages from replicators who have opened “replication” folders only to find names, Social Insurance Numbers, mental-health diagnoses and incomes of study participants. 🧵

Not having kids is not a remotely effective climate mitigation strategy

🚨 Replication update! The Journal of Population Economics has RETRACTED Ciacci (2024) 🚨 It seems like the scientific record can be corrected after all. This paper does not show that the Swedish law that criminalized the purchase of sex led to an increase in rape. 1/4

Meh. As a big defender of USAID, I’d say the agency deserves little credit for the global reduction in (monetary) poverty. But… 1/2

"I guess Jonny [Narvaez] doesn't take jokes and my microphone wasn't working so I was like ok, I follow Jonny" Tadej Pogačar said attacking from the bottom on Hautacam wasn't the plan 💛🇸🇮 #TDF2025

Why don't British homes have air con? The 3 problems that are leaving us too hot at home when the temperature soars, and our three point plan to solve them and cool Britannia.

This series of papers evaluating cash transfers in the US has produced disappointing results for advocates. These are important results. However, when reading them it’s worth keeping in mind that cash transfer studies have produced very positive results in lower income countries.

Abel is awesome (and very fun to talk to), and his replication work is super important. Really glad that Open Phil supports I4R openphilanthropy.org/research/how-t…

This is really exciting and impressive, and this stuff is in my area of mathematics research (convex optimization). I have a nuanced take. 🧵 (1/9)
