🆕 Why workers avoid unfamiliar neighbourhoods – and how one visit can help eliminate fears Today on VoxDev, Josh Dean (University of Chicago), Gabriel Kreindler (Harvard University) & Oluchi Mbonu (World Bank) discuss barriers to job search in Nairobi: ow.ly/eHPL50ZFYqG

Why workers avoid unfamiliar neighbourhoods – and how one visit can help eliminate fears
A field experiment with casual workers in Nairobi finds that people are reluctant to work in unfamiliar parts of their own city. A single visit to an unfamiliar neighbourhood is enough to eliminate this aversion.

In South Africa, one of xenophobia’s quieter moral mechanisms is the way foreign wrongdoing is made to carry more meaning than citizen wrongdoing.

The United States is now a country where soldiers with powerful military weapons can and will detain you simply because you are not white. It’s not hidden. The Supreme Court has explicitly approved the practice. Rare bodycam footage of what it looks like in practice, from local police partners—>

The end of Viktor Orbán’s ‘Hungarian model’?

Much of the econ discourse around increasing use of agentic coding revolves around implications for the demand for RAs, predocs; wanted to do a short post on how I see this unfolding for those of us, whether inside or outside universities, who primarily conduct development field research.

I knew that the Department of War shot a missile into a school & killed 175 civilians, mostly children. This is learned today: Secretary of War Hegseth had cut the teams assigned to prevent such tragedies by 90%. www.npr.org/2026/03/11/n...
After a series of fatal strikes involving civilians in Iraq and Afghanistan, Congress directed the Pentagon to reduce civilian casualties as part of a 2019 law. During the Biden administration, the Defense Department created the Civilian Harm Mitigation and Response initiative.

The civilian mitigation teams – cut by 90% by Hegseth – work with military commanders on target planning, and making sure that targets are actually military sites. The teams help come up with "no strike" lists, including religious and cultural sites and schools

"I am Puerto Rican," she says. "I send my kids with their passports to school. I'm having conversations with them about safety: Am I safe at school? A week ago we had an incident where there was a school bus with the STOP sign open and kids were getting on the bus and it was surrounded by ICE agents. And this is 7:20 in the morning and - just - you get that fight-or-flight response." At first her 9-year-old was carrying her passport in her backpack; now it's in her back pocket. "I have to prepare them for it if they get stopped," she says. "I said, Do not engage. This is not the time to be cussing at anyone. But she said, Mom, if I create enough noise, my friends can get away."
