You’ve seen the news about the administration’s proposed change in green card processing. Lest you think this is just a meaningless rule change, here’s my experience:

This is a phenomenal piece showcasing the economic harm done by ICE, with poignant examples. I appreciated contributing a bit by sharing the results of my recent study. www.bloomberg.com/news/feature...

Thank you for covering my research. But more important than who authored the study is the fact that real people, real businesses, and real communities are being harmed by the current approach to immigration enforcement.

*** NEW RESEARCH *** Images of ICE targeting US cities have been commonplace in since January 2025. What's the economic effect of this new immigration enforcement regime on businesses, both workplaces and retailers, in targeted areas? Thread... 🧵

The US Administration has proposed a new rule that would bar almost all asylum-seekers from legally working, for at least a decade. My colleagues and I have written and submitted a detailed analysis of how this act will impact the United States economy. 🧵—>

Since #Claude now does 90% of your admin work, you have lots of free time to do the fun stuff in academia. 😉 Join us on Thursday (8:30am PT) for this super timely research from @profzeke.bsky.social on the impact of #ICE enforcement on American businesses.

I’ve seen the video recorded by the woman in the pink jacket. It made me cry. It was murder. Shame on ICE and anyone who tries to defend their actions in this incident.

This is horrific. Absolutely no plausible justification. Straight up murder.

NYC friends: Stop by the Lincoln Center tonight at 7 pm for a conversation about the American dream! This is part of a series to commemorate the 250th anniversary of the United States. Timely and timeless!

ICE melts when exposed to evidence

The US Administration has been claiming that mass deportation has opened up jobs for US workers. But that’s an incompetent misreading of the data. @stanveuger.bsky.social of AEI explains their freshman mistake. www.washingtonpost.com/business/202...

Merry Christmas!

There are 75,977 people born in Somalia who are now citizens of the United States, including those specific people. He is talking about US citizens. He is talking about *us*. The truth is that none of us are garbage, and the job of the US president is to represent all of us. We, the people.

International students *create* educational opportunities for US natives. Each additional Chinese master's student causes enrollment of 0.26–0.44 additional native students, by funding/expanding master's programs. New at @nber.org—> doi.org/10.3386/w34391 Ungated: www.dropbox.com/scl/fi/giykh...

My take on how the H-1B fee affects jobs and innovation: time.com/charter/7321.... Thanks to Charter and Time for the opportunity to weigh in.

And I’m honored to support such a sensible, no-brainer cause that’s only good for our country.

Glad to see the US Chamber of Commerce speak up on the $100,000 H-1B tax. I’ve been hoping the business community would speak up more forcefully on immigration issues. It’s a constituency that will be heard by the administration. This is a good start, but only a start.

The Truth About Immigration by Zeke Hernandez is essential reading for understanding the economics of immigration and the statistical truth. #Politics #Economics #NonFiction #Audiobooks #NetGalley #BookSky 💙📚 @profzeke.bsky.social @stmartinspress.bsky.social www.goodreads.com/review/show/...

The recent action by the administration to impose a massive, $100K per-head tax on skilled labor is a huge source of talent uncertainty. As this research shows, one thing you can expect is less investment by firms. This is bad for American workers, businesses, and economies.

If confirmed as true, this would be the height of hypocrisy. The man who so vehemently claims to be on the right side of the law would actually be a crook.

Really excited that the Immigration Policy Lab is doing this, and honored to be one of the presenters this season. We need all the evidence we can get our hands on when it comes to immigration, and this is a great way to disseminate it.

What does mass deportation mean for the US economy when the native workforce is in sharp demographic decline? I spoke at the Invest in America Summit by @thehill.com Video at 2:04:03 & thereafter—> www.youtube.com/live/h3Opi4w... cc @piie.com

*** NEW RESEARCH ALERT *** How do firms respond in the face of increased restrictions to hiring skilled immigrant workers? [THREAD]

Department of Government Efficiency (in spending your taxpayer money)

This article in the latest edition of the American Economic Review is purely theoretical, of course. No connection to reality… 🙄

Cronyism at its finest. When every company has to cut an individual deal with the government, you don’t have institutions anymore. In an institutional system, the rules ensure everyone is treated the same according to fair principles. This is not the case anymore in America.

If we knew the truth, we’d be excited and united about immigration. Learn why in this TED conversation between Sonia Shah, Whitney Pennington Rodgers, and me. We need immigration to remain innovative—biologically, economically, culturally, and in every possible way. www.ted.com/talks/sonia_...

Important work! Thank you for doing this research.

Shame! Shame on the Trump administration for stripping legal status from thousands of our ALLIES, including many we evacuated from Kabul ourselves! This makes our country utterly untrustworthy. No future ally will ever believe our promises; all can be taken away. We lose our honor.

Excellent visualization of how much we depend on immigrant workers for our food. Take a moment to internalize the numbers in this article. With aggressive deportations + sky-high tariffs, get ready to pay a lot more for what you eat!

The secretary of agriculture has suggested people on Medicaid can replace deported farmworkers. This is simply not true. I appreciated the chance to be on @velshimsnbc.bsky.social discuss this with @velshi.com & @julierovner.bsky.social. www.youtube.com/watch?v=xz8K...

🤦‍♂️ There’s a phrase in Spanish that perfectly captures the feeling of watching this: “vergüenza ajena.” It loosely translates as feeling embarrassed for someone else—in this case, for the United States of America.

New macroeconomic analysis from the Dallas Fed: Mass deportation will reduce US GDP growth by 0.89 percentage points this year and 1.49 percentage points by 2027 It doesn't have to be this way. The choice isn't border chaos or vast militarized raids. The third option: lawful channels for migration

🆕 Why ‘Brain Drain’ is an incomplete story of migration 📢 Today on VoxDevTalks, @catiabatista.bsky.social (@novafrica.bsky.social) & Caroline Theoharides (Amherst College) discuss the channels through which emigration can benefit origin countries: voxdev.org/topic/migrat...

I don't agree with the administration's current approach to immigration enforcement, but this is not the way.

A few weeks ago I met the man in the middle of this photo, one of the few remaining Japanese Americans interned during WWII. His family was forced from California and sent to a camp thousands of miles away when he was a child. A new paper shows the economic damage from tragedies like this one.

Posting something beautiful because we all need it.

Please pay attention to this… And yes, there’s so much else to pay attention to right now!
