En esta entrada resumo un nuevo documento de trabajo co-autorado con mis increíbles colegas @chrambrosio.bsky.social y Juliana Quigua: www.iza.org/publications...

First day at the Conference Redesdal! A perfect day at my alma mater @uniandes.bsky.social full of great presentations, a chance to reconnect with friends & colleagues, a talk by former president Juan Manuel Santos, & insights from Maria Jimena Duzan on communicating research to a wider audience.

In case you missed it, this new immigration enforcement dashboard contains detailed data from the deportation data project, no affiliation, and will be updated in the coming weeks with detainer data and detention data. Stay tuned and follow me here and on Substack for announcements.

This is another crippling blow not just to high-skill immigration in America, but specifically to the talented students who come here to study at US universities in the hope of staying to contribute their skills to the US.

There won't be many chances to do that anymore. Door slammed in their faces.

You've likely seen the new $100,000 penalty on high-skill immigrant workers.

Here's the next, separate bomb the White House is dropping on high skill immigration, to be officially published *tomorrow*.

tl;dr: Most H-1Bs now inaccessible for entry-level jobs, e.g. new grads from US universities.

New US curb on high-skill immigrant workers ignores evidence of its likely harms President Donald Trump on Friday ordered an unprecedented new restriction on lawful immigration to the US by high-skill workers. Starting Sunday, new applications for H-1B visas required payment of an...

Very useful summary by @mclem.org of the evidence on skilled migration and the likely impact of Trump's H1B visa fee.

Do People Like Refugees more than Economic Immigrants? A simple question that our best research still hasn't settled

Do voters prefer refugees to economic immigrants? A simple question that decades of social science still can't answer.

In my new piece, I go down the rabbit hole of why the evidence is mixed, and what that means for debates about populist accommodation.

Who is Arrested by ICE under Trump 2.0? A 🧵

New from me & @elizabethacox.bsky.social!

I also want to thank my amazing co-authors. We learned a lot writing this paper. Every iteration made it better, & I truly enjoyed every single one of our meetings & brainstorming sessions. We are more motivated than ever to keep working on these important topics for the region!

This paper greatly benefited from seminar discussions & from the thoughtful suggestions of two anonymous referees & our editor, Lucas Davis.

It was a rewarding & intellectually engaging process. The feedback helped us strengthen the evidence we present on this important topic.

These findings go beyond El Salvador. Approx. 30 million farms in low-income countries operate under similar conditions: high climate risk, limited formal insurance, & access to remittances.

Understanding these dynamics is key for increasing the resilience of countries to extreme weather events.

Migrant networks matter.
The migration response is strongest in areas with more established U.S. networks, which help lower the cost of migration and make it a viable option.

We find multiple responses:

• Reduced use of production inputs
• Decline in demand for non-household labor
• Increased reliance on international migration

One additional week of extreme heat raises migration among corn-producing households by 0.15% points, a 23% increase relative to the mean.

We start by showing that extreme temperatures during the main growing season reduce corn yields by 3% and hired labor by 3.6%. So how do agricultural producers respond to these shocks?

In this paper, we study how extreme temperatures affect international migration in El Salvador—a country with strong U.S. migration networks and a population heavily reliant on remittances and subsistence agriculture.

I am excited to share that our paper "Responses to Extreme Temperatures: Migrant Networks and International Migration from El Salvador" with @anamibanez.bsky.social, Juliana Quigua and @jimenaromero.bsky.social has been conditionally accepted at the AEJ: Economic Policy! #econsky #academicsky

Big thanks to the scientific committee for including our paper, to all the participants, and to the founders of HUMANS, Ana María Ibáñez, Marcela Meléndez, Antonella Bandiera, and @sandrarozo.bsky.social, for building such a strong network of people working on migration.

Days 2 and 3 in Mexico City presenting our work with @chrambrosio.bsky.social and Juliana Quigua at the HUMANS LACEA Network (working paper coming soon!). Always inspiring to connect with so many people who have shaped my own work on migration.. #econsky #academicsky

Day 1 in Mexico City talking to an impressive group of undergrads at ITAM’s Econ Week. There’s a lot of hope when you get to meet students like them. Thanks to Arturo Aguilar for the invitation!

It was so great seeing you @chrambrosio.bsky.social in such a great conference! #econsky

Huge thanks to our wonderful co-author, Juliana Quigua, for presenting our paper, "Externalities of U.S. Immigration Enforcement Policies in El Salvador", at the RFBerlin Migration Forum! Grateful for the opportunity to share our research. @rfberlin.bsky.social

Grateful to Carlos Vargas-Silva for presenting "Trust Beyond Borders: The Role of Non-State Actors in Shaping Immigration Preferences" at the inaugural seminar series of the Migration Unit at IDB. His contributions are invaluable to migration discussions in the LAC region!
