Some context: I used to ask “what are you working on?” but I learned some people would rather not talk about it for various reasons. So the more general “what are you excited about in your field?” lets them EITHER talk about what they’re working on or some other interest.

Fellow economists, what kind of question would you most like to be asked when meeting someone at a conference? #EconSky
1. What are your working on?
2. What is your field?
3. What is exciting in your field?
4. Other: spill the beans!

Common Ownership & Employee Earnings
updated & improved

Consider a pair of companies that sell into the same product market. If pair shares common owners, the owners have incentive for pair to soften competition.

Same with local labor market competition
papers.ssrn.com/sol3/papers....
Common Ownership and Employee Earnings * José Azar Xin Dai Yue Qiu Aaron Sojourner September 15, 2025 Abstract Using administrative data in the manufacturing sector from the U.S. Census Bureau, this paper provides the first evidence on the effect of common ownership on employee earnings. Using firms’ additions to the S&P 500 index as a shock to their local competitors’ common ownership, we find that, after a same-industry competitor enters the S&P 500 index, the average employee earnings of S&P 500 incumbents in the same local labor market decrease. Additionally, these firms’ employment increases. These findings are inconsistent with the canonical oligopsony models but our generalized model of oligopsony incorporating a recruitment intensity margin can rationalize them

A center for conservative thought creates a market test: can its scholars develop logical, strong, useful ideas that stand up to the intellectual questioning of students and colleagues? It may be hard to defend racism & autocracy good, science bad, oligarchs should get all society’s wealth, etc

“Us vs. them” mentality is not the way to intellectual progress nor to a healthy democratic debate.👇

There are no homogeneous blocks but loose webs of ideas and those in power pick and choose depending on the interests of the moment. Having a stronger broader web of ideas that have been tested through intellectual debate is useful.

This would be an extremely bad idea. It will not satisfy them. It will acknowledge that they are right about something. It will empower them. Literally nothing that anyone should do, should be oriented towards placating this administration.

Very excited that our paper (joint with Jarkko Harju and ‪@schoefer.bsky.social‬) on "Voice at Work" is published in the American Economic Journal: Applied Economics. We study what happened when workers in Finnish firms got a right to worker voice on the corporate board. 👇

Yes, continuing unemployment claims are up, but the US labor market remains remarkably stable across most indicators in 2025. Context matters: this is a slight softening, not a crisis. My analysis in @Forbes.com explains the full picture www.forbes.com/sites/zachar... #EconSky​​​​​​​​​​​​​​​​

The report looks strong. The Powell attack was disconnected.

+147K jobs gained last month (mid-May to mid-June).
+16K jobs in revisions of prior 2 months

EXTREMELY BAD NEWS for economic research, per former BLS Commissioner @ericagroshen.bsky.social on LinkedIn.

BLS is suspending access to its restricted data "for the forseeable future." Applies to projects through the Federal Statistical Research Data Centers & onsite projects with BLS.

If you do this since 1929, it's even worse.

Today was worse than 99.6% of trading days since 1929. It was the 95th worst day of all time (out of >24,000 days), and the 35th worst day since 1945.

Are the 2020s the disaster decade? David Brooks thinks every historical time has its own disaster, except maybe the 1990s. I grew up in the 1990s, so maybe that’s one more way I’ve been very lucky. What do you think? 1990s yay or nay? 🤔
