🆕 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: https://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.

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—>

My 2 cents @goodauth.bsky.social on Orban's loss in the Hungarian elections based on survey data from last week. goodauthority.org/news/the-end...
The end of Viktor Orbán’s ‘Hungarian model’?
New data show why Orbán’s Fidesz party finally fell after 16 years in power.

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.

Need alternative to PDF. Reading research articles as PDFs on a phone screen is miserable. LLMs consume plain text more easily. I used Claude to write a pipeline to convert my LaTeX to HTML with the Tufte CSS. Here’s Dingel and Neiman (2020) as a webpage: www.jdingel.com/research/Din...

this is valuable. The future of reproducibility could be interesting: Step 1) stress test existing replication packages using new AI tools to catch errors or non-robust findings Step 2) Publishing work with errors will become much harder if such checks become standard or anticipated
🚨Replication alert🚨 I'm pleased to announce that my replication of Moretti (2021) is now accepted as a comment at AER. I find ten issues in the paper. My comment focuses on two major problems; in the appendix, I document eight (relatively) minor problems. 1/

Taxing rich people into oblivion is good for democracy. The revenue generated, while not sufficient for our purposes, is just a secondary benefit.
It will not work, and is wrong in principle
