Can we tell from the data when and how treatment effects generalize across different individuals and contexts? Exciting new working paper, joint with Emily Breza and Arun G. Chandrasekhar that studies generalizability for applications to external validity, effect heterogeneity and model discovery

i just want to convey the depth of my appreciation to our colleagues, in the broad sense, in the american and UK university systems, for continuing to teach the fact that trans people exist even though you are all going to be ceaselessly punished alongside us for it. thank you.

So, a university president fired a professor because they taught a course that discussed there being more than two genders, and now the university president is being fired for not having fired the professor quickly enough, is where we're at. www.nytimes.com/2025/09/18/u...

I was the AEA's President Elect as the first Trump term began. We worried about government statistics then, and appointed a committee that included members (such as Google's Chief Economist) who might be in a position to help make reliable statistics available if the government went dark.

Statement from the largest economics association about the BLS firing

As context: AEA approximately never makes such public statements

This is a big deal

AMERICAN ECONOMIC ASSOCIATION
Committee on Economic Statistics and Committee on Government Relations

Statement from the American Economic Association on the
Dismissal of the BLS Commissioner

Leaders of the American Economic Association express their grave concern over the dismissal of the Commissioner of the Bureau of Labor Statistics (BLS) earlier today.
The independence of the federal statistical agencies is essential to the proper functioning of a modern economy. Accurate, timely, and impartial statistics are the foundation upon which households, businesses, and policymakers make critical decisions. Undermining the independence or credibility of these agencies threatens the integrity of the information that markets, institutions, and the public rely on every day.
Measuring the vast and dynamic U.S. economy in real time is inherently challenging. It is standard practice for statistical estimates to be revised as more complete and higher-quality data become available. These revisions reflect the commitment of statistical agencies to accuracy, transparency, and methodological rigor-not failure or bias.
The BLS has long had a well-deserved reputation for professional excellence and nonpartisan integrity.
Safeguarding this tradition is vital for the continued health of the U.S. economy and public trust in our institutions.
We call upon elected officials to respect and preserve the independence of the nation's statistical infrastructure.

Dr. Erika McEntarfer has devoted her career to public service. She has conducted herself as BLS Commissioner with great integrity. There is no evidence whatsoever that BLS data are politically biased.

🆕 How economists are using new data sources in development economics

Research on @voxdev.bsky.social draws on a variety of data sources - satellites, phones, leaks & more.

In this blog, I highlight what we learn about development from these novel data sources: voxdev.org/topic/how-ec...

How economists are using new data sources in development economics

Development economists are harnessing satellite imagery, mobile phone metadata, government tax records and even leaked documents to answer questions that were previously out of reach.
