🔥Very cool paper showing that women in India are way more likely to take up a job (↑29%) in a female-only workplace, and that this can be explained by husbands' jealousy/desire for control. These are massive effects, equivalent to 2.5x increases in wage bit.ly/4nn9apn

Good morning with good news: India meets 50% renewables & nuclear capacity target 5 years early! As clean capacity deploys, clean electricity production surges. Solar grew from 5 TWh in 2014 to 48 TWh in 2019 & 137 TWh in 2024. Hydro was 157 TWh; wind 82 TWh; nuclear 55 TWh in 2024. #energysky

In the last decades, the world has made fantastic progress against extreme poverty. In 1990, 2.3 billion people lived in extreme poverty. Since then, the number of extremely poor people has declined by 1.5 *billion* people. 🧵

A stacked area chart showing the total population (split by World Bank region) living in extreme poverty, defined as living below the International Poverty Line of $3 per day. Shown from 1990 to 2025, with World Bank projections from 2026–2040. The data is adjusted for inflation and cost of living differences. Rapid progress against extreme poverty in recent decades has slowed and is projected to end. In 1990, 2.3 billion people lived in extreme poverty. Since then, the number of extremely poor people has declined by 1.5 billion people. The number of people in extreme poverty is projected to decline, from 831 million people in 2025 to 793 million people in 2030. After 2030, the number of extremely poor people is expected to increase. The data source is Lakner et al (2024), updated using the World Bank PIP (2025).

On one hand, reducing car use reduces urban pollution. But on the other, everyone likes it and cities become more livable

Average nitrogen dioxide concentration in Paris has fallen significantlyHer proposals have faced pushback — from right-leaning politicians, a car owners’ association and suburban commuters, who say that targeting cars makes their lives more difficult. But last month, Parisians voted in a referendum to turn an additional 500 streets over to pedestrians. A year earlier, Paris had moved to sharply increase parking fees for SUVs, forcing drivers to pay three times more than they would for smaller cars. The city has also turned a bank of the Seine from a busy artery into a pedestrian zone and banned most car traffic from the shopping boulevard of Rue de Rivoli. Carlos Moreno, a professor at Paris 1 Panthéon-Sorbonne University and a former adviser to the city, said the French capital has developed “an urban policy based on well-being.”

“Over the past 20 years, Paris has undergone a major physical transformation, trading automotive arteries for bike lanes, adding green spaces and eliminating 50,000 parking spaces. Part of the payoff has been invisible — in the air itself.” Leadership, strategy, real action, common sense. #Paris

🎙️ In a recent @voxdev.bsky.social talk, NOVAFRICA Scientific Director @catiabatista.bsky.social & Caroline Theoharides discuss key findings from their @science.org paper: “Brain Drain or Brain Gain? The Impact of High-Skilled Migration on Origin Countries.” 🔗 voxdev.org/topic/migrat...

Why ‘Brain Drain’ is an incomplete story of migration

The migration of high-skilled workers, sometimes referred to as 'brain drain', is usually seen as negative for origin countries. New research suggests this is an incomplete story—highlighting the chan...

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers. The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

Since 2000, Gavi has helped get vaccines to 1.1 billion children. The U.S. announced that, after this year, it’s pulling out all its money. If that happens, Gavi estimates that 75 million children will miss vaccinations over the next five years—and of those, 1.2 million children will die.​

USAID has spent $2 billion supporting vaccines through GAVI. In research, published in AEJ:Economic Policy, Kartini Shastry and I find GAVI saved 1.5 million lives at a low cost of $9,000 per child saved. See the writeup of our research in VoxDev: voxdev.org/topic/health...

The global vaccine campaign GAVI saved 1.5 million lives so far, as economists @dantortorice.bsky.social and Kartini Shastry have shown. Now the US Administration, captured by anti-vaccine zealots, will cancel *all* funding for GAVI. www.nytimes.com/2025/06/25/h... An act of mass death.

This is a travesty & a nightmare. The US was a founder of @gavi.org. It lowers global vaccine costs, has vaccinated 1B children, & averted 19M deaths. This pull out will cost 100s of thousands of children's lives a year - and RFK Jr will be personally responsible. www.politico.com/news/2025/06...

Kennedy ripped into Gavi, the Vaccine Alliance, in a video address at its pledging summit.

The CBO has analyzed the distributional impacts of H.R. 1, a.k.a. the One Big Beautiful Bill Act. Household resources for the bottom income decile would fall by 4% ($1,600), largely due to Medicaid & SNAP cuts. The top income decile will see increases of 2.3% ($12,000), largely due to tax cuts.

At Princeton today to celebrate the career of the brilliant and generous Janet Currie, a pioneer in the economics of children. I and the many researchers in this audience wouldn't be where we are if not for her mentorship.
