I was accepted into the AEA Mentoring Program!

As an orphan in a PhD means no blueprint/support —literally zero. That's why these programs matter so much. They remind you that others who have made it will help, to "Lift as You Climb" as @itsafronomics.blacksky.app would say.

Absolutely fantastic visualization by @home-economics.bsky.social, this is ~7 variables of 30 countries across 20 years designed in a way that feels quite clean.

The Economist Who Wants to Solve America’s Wage Problem The economist Arindrajit Dube believes that the answer to fixing America’s wage problem is to empower workers and set mandatory wage standards across industries.

Very appreciative of the in-depth discussion of The Wage Standard in The New Yorker by @johncassidysays.bsky.social

🚨New Working Paper🚨
Economists Should Fix the Economy
WP: papers.ssrn.com/sol3/papers....

Economics maintains a general disposition against prescriptive work. But this is in stark contrast to the overwhelming view by the public that economist should be involved in policy.

Economists Should Fix the Economy: The Public Expectation of the Policy Obligations of Economists Nine in ten Americans-90 percent of survey respondents-believe economists should play some role in shaping economic policy. This is not a study of policy prefer

🚨New Working Paper🚨 "Economists Should Fix the Economy"

9 in 10 Americans think economists should play some role in shaping economic policy. Only 10% want economists to stay research-only.

Would appreciate shares, feedback, and pushback.

JOLTS release once again confirming that the no-hire, no-fire labor market continues. Also lines up with UI claims, which also show no signs of layoffs picking up.

The Effects of California's $20 Fast Food
Minimum Wage on Prices
Jeffrey Clemens, Olivia Edwards, Jonathan Meer &
Joshua D. Nguyen
WORKING PAPER 34990
DOI 10.3386/w34990
ISSUE DATE March 2026
We analyze the effect of California's $20 fast food minimum wage (Assembly Bill 1228), enacted in September 2023 and implemented in April 2024, on consumer prices using the Bureau of Labor Statistics Consumer Price Indices for food away from home across 21 metropolitan statistical areas. Food away from home prices in California's four in-sample MSAs increased by 3.3 to 3.6 percent relative to 17 control MSAs through December 2024. Our estimates are stable across a number of specifications. Placebo tests on price indices for goods and services that were not affected by the policy, including food at home, show no differential increases in California's MSAs.
The price increases we estimate likely arise in part from spillovers to the full-service sector, as well as changes in the production functions and product quality choices of limited service restaurants.

CA’s $20 fast food minimum wage raised fast food prices by only 3%. The reason minimum wage increases keep not reducing employment and barely increasing prices is monopsony power.

The Economy is Scam Likely As the Economy Enshittifies, so Does the Inflation Data, which Informs Everything from Wages to Benefits but the Data was Not Designed to Capture Issues of the 21st-Century —but Maybe it Should.

What if inflation data isn't "wrong," but just wasn't built for the 21c?

CPI is load-bearing —tied to wages, benefits, COLAs— so even a small drift compounds. Not just because prices are rising faster than it captures, but because wages linked to it end up lower than they should be. #EconSky

Also, many thanks to @maggieecjones.bsky.social Professor Jones was incredibly generous with her time in giving me feedback and helping me construct the slides. Her knowledge of the format was especially helpful, and it was a real pleasure to finally meet her in person.

Professor Logan has been an extraordinary mentor—not just in shaping the scholarship, but in helping people, especially students who come from disadvantaged backgrounds, to navigate academia with a real commitment to mobility and equity.

Bar graph titled "Women are paid less than men at every education level" and subtitled "Average horly wages, by gender and education, 2025"

Women with an advanced degree are paid the same as men with just a bachelor's. And at every education level, women's hourly wages are about 20% lower than men's

Incredible work!

Somewhat depends on how you count the beans, but it’s worth noting that wages for Asian/White women is typically higher than Black/Hispanic men. Asian women in the aggregate have higher pay than white men. With Asian men’s pay above all categories.

WA passed a Millionaires Tax. Instead of celebrating the *many* benefits of taxing the ultra-rich, headlines are asking “Will the rich flee?!” 😑

This claim’s been tested. Large-scale tax flight does not happen. And even when a wealthy few leave, gains for everyone else win out.
