Michael Clemens

In my keynote at the @DallasFed / @SMU last month, I explored the root causes of the policy crisis at the Southwest Border Video of my slides, audio of me—> youtube.com/watch?v=G8rPhG… (starts at 9:42, with gracious introduction by Pia Orrenius)

I was pleased to join a distinguished group of economists in signing on to an amicus brief organized by @m_clem in Mullin v. Doe and Trump v. Miot, the Temporary Protected Status (TPS) cases currently before the Supreme Court. The brief provides an overview of the overwhelmingly negative economic consequences of terminating TPS for most or even all beneficiaries. Signatories include @DAcemogluMIT, @leah_boustan, @AmuedoDorantes, @ChloeNEast, @raquel1fernan, @FurtadoDelia, @BrittaGlennon, @profzeke, @CJ_Heinrich, @baselinescene, @ethanglewis, @mayda_anna, @PMoserEcon, and @melaniemorten.

In 2025, the US government imposed a $100,000 tax on each high-skill foreign worker entering with an H-1B work visa. Read @m_clem's empirical take-down of this new tax docs.iza.org/dp18435.pdf

“Across all sectors collectively, [unauthorized] immigrants are simply adding to overall employment in each city, not pushing any natives or authorized immigrants out of their jobs,” @m_clem says. cnn.com/2026/04/28/eco…

The Migration & Organizations conference is a superb annual academic meeting that unites scholars of management, economics, and sociology studying the effects of international migration Hosted at @upenn.edu Wharton School, May 26–27

The US Administration has ended deportation protections for nationals of 13 countries so far. Writing as lead amicus, I join with 3 Nobel laureates and 16 other leading economists to assess the economic impacts of these actions, in a new brief for the Supreme Court. cc @PIIE

It is my honor to join these world-leading colleagues to inform the Court and the public about this research. Our full brief is here—> supremecourt.gov/DocketPDF/25/2…

While the Administration claims public safety motives for some of these terminations, the research literature has found no basis for those claims. Selective+inflammatory anecdotes do not alter that conclusion; it's trivial to gather bad anecdotes on any disfavored social group.

Lemkin 1947—> jstor.org/stable/2193871

The man who coined the term genocide, Raphael Lemkin, defined it as a greater atrocity than mass murder explicitly because it involves the intentional killing of a civilization.

@cortespatico Mil gracias Patricia 🙏🙏 Qué lindo de tu parte

@m_clem Felicitaciones Michael!

I'm honored and excited to join the faculty of America's oldest research university, Johns Hopkins. I'll start this summer as a full professor, one of the founding faculty at the brand-new School of Government and Policy. We're building something unique & historic.

@maya_sen Maya that's so kind of you, thanks. 🙏 I've learned a ton from you online over the years and look forward to much more

@IlyaSomin Thank you so much Ilya. 🙏 Your impact cannot be overstated. Mason has been simply wonderful to me in every dimension and this is not something I was out looking for. But it's a vanishingly rare opportunity for my own greater impact and I'm very excited to seize it

Congratulations to the world’s greatest immigration economist! We will miss him at GMU.
