New paper with @arielburst on aggregate productivity in economies with discrete choice and household heterogeneity. In these settings, measures like real GDP, average utility (across agents), and sum of compensating variations have serious flaws. A brief summary below. 1/7

Queste giovani ragazze iraniane costrette a indossare un velo e che si rifiutano di cantare l’inno in segno di dissenso, col rischio di finire in carcere o appese alle gru, rappresentano per me la vera lotta per l’emancipazione femminile. Le soldatesse ucraine che lottano contro

Thank you President @realDonaldTrump for urging Australia to protect these Iranian players. Also, thanks to @jk_rowling for using her voice to support these brave girls. We Iranians never forget those who stand with us in our darkest moments.

🇨🇭 Today Switzerland voted in favor of individual taxation. A good law that eliminates the marriage penalty and promotes female labor market participation. Excellent way to celebrate international women day

From Inside Iran: After a few days, I finally managed to connect. Last night, I went shopping and saw 15–20 people marching with Khamenei banners, holding mourning ceremonies, and causing heavy traffic. Armed men were around them. Some cars honked to clear the way, and in front

If someone told me a semiconductor shipment was late because it was the wrong phase of the moon, I would not have believed them before reading this paragraph!

As an Iranian living inside my country during war, I will say this plainly. The chance of me being killed by masked, armed men roaming the streets, or by gunmen standing on mosque rooftops behind machine guns, is far greater than the chance of dying in an airstrike. That is the

Not pictured in this silly image of 1950s America: ☑️ That this house is probably 1000 square feet, lacks AC, and a washer/dryer. ☑️Those kids own 6 outfits and a small number of toys. ☑️ The family takes no vacations beyond the local lake and goes out to eat once every 2

A 20 min presentation at the NBER EFG of my paper with @arielburst. How to measure aggregate productivity with heterogeneous agents. Our measure identifies when changes are "positive sum" without taking a stance on how resources should be distributed.

I am happy to share that in Fall 2026 I’ll be joining @PSEinfo as an Assistant Professor! I’m deeply grateful to my advisors Lee Ohanian, @itskhoki, and @arielburst, and the amazing UCLA Econ community for their support and guidance. Huge thanks as well to my friends and family!

How the Islamic Republic treats the Iranian people during wartime: There are no air raid sirens or shelters. Authorities also shut down the internet and are jamming satellite signals from diaspora news channels, preventing access to information.

An experimental arm designed to test reduction in parachute failure rates demonstrates a 90% reduction... but this led to only a 1 second improvement in life! One second!! How worthless!! Disclaimer: we stopped measuring the benefit of the "life saved" once people touch

I am going to remind people continuously that maximizing government revenues is not inherently a good thing. You should want to maximize wellbeing, income, social mobility, environmental quality etc. None of these are tied to government revenues automatically

It’s great to see the ⁦@WSJ⁩ pointing this out! “The elderly are physically and financially healthier than ever. So why do their needs keep taking priority over younger generations?”- ⁦@greg_ip⁩ ⁦@WSJ⁩

@itskhoki + my signature third edition of the Jackson Hole International Trade, Macro and Finance conference was a huge hit. POW + suberb research. Thank you all! @arielburst @fab_perri @skalemliozcan @glviolante @roozbeh52 Check out the program here: https://t.co/9XgAwqXvIn

It was a remarkable and painful experience for me. I turn 60 tomorrow and as I think back; this was the low point of my career. Our paper is very good. It wasn't perfect but it didn't deserve the death penalty. My perspective is presented here; https://t.co/XUSXUlF7z5

If you like @RefineInk and are interested in working with us to scale distribution/marketing, please DM. Must "get" the product and have relevant experience. About a half-time gig.

@JesusFerna7026 I like it. I think Hicks is the most underrated economist in the 20th century. He played a foundational role in micro, macro(Keynesian and RE -Lucas cited his device of time-dating goods) and economic history + the evolution of his allegiance, from Walrasian/Pareto to Menger

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

David Lagakos and I have a new review of development accounting ( https://t.co/sCHTGS5fGh). We ask: what have we learned in the two decades since Caselli’s seminal Handbook chapter? (1/7)

it really seems like covid/the existence of "virtual school" has just broken the public education contract irrevocably, no one really seems to expect school to actually function well or reliably anymore
