@cblatts Its ability to manage local files is the main point to me. In a survey, it can automatize running high frequency checks, assign random spotchecks and backchecks, cleaning, analysis, etc., and even send emails to surveyors and PIs. Nice example here: producttalk.org/claude-code-wh…

Approximately 1/3 of my X feed is people gushing about Claude code. I’m already an intensive ChatGPT user so I am open minded. And I will try it. I can't help but wonder: 1. Why do most of these posts sound like they were written by their AI? 2. Is this a viral marketing campaign? 3. Is this just the Twitter algorithm running wild? 4. Why don't I understand from these posts what these people are actually doing with Claude? Why is it all in vague gobbledygook? They talk about tasks in weird jargon, and it's like they're speaking a different language. I really don't understand what 5. Can someone explain in plain English what I would as an academic would do concretely with Claude code? We are already testing it out to clean and analyze basic survey data where it does okay. I'm going to be trying to play around with some new theoretical models, adapting IO models to criminal firms where ChatGPT has been doing ok. Will Claude code do better? Anything else I should be thinking about kind of work they're doing.

Thanks to the Council on Latin American & Iberian Studies @YaleCLAIS for making this engagement possible. Keep posted for the coming article. (4/4)

I am grateful to Professor Kalyvas, the discussant, and all participants for their thoughtful feedback and engaging questions. It was an inspiring opportunity to explore how these dynamics play out across Latin America and to connect with scholars from diverse backgrounds. (3/4)

This week I had the privilege of presenting my research at the T. E. Lawrence Program on Conflict and Violence at the All Souls College at @UniofOxford, invited by Professor @SKalyvas. 🧵(1/4)

@mathoyos @CityCollegeNY @CUNY @CIDE_MX Felicitaciones @mathoyos!

Two big news today and I couldn’t be happier: my first day as economics faculty at @CityCollegeNY–@CUNY, and the acceptance of my job market paper on tariffs and growth (more on it soon, stay tuned). Forever grateful to Mexico and @CIDE_MX for being home these years.

@BigBigBLessing Congrats Ben! Happy to see this great work published

How many people live with criminal governance in the Americas? Based on nationally representative survey data, we offer a rough estimate (Spoiler: as many as 100 million). Criminal governance also seems to be systematically correlated with greater, not weaker, state presence.

@oscarbalmen @oscarbalmen toda mi solidaridad contigo y tu familia en este momento. Un abrazo

Dejo constancia: hoy recibí tres llamadas de un número privado que me han dicho que me van a matar, si sigo investigando crimen organizado. Mi mensaje: yo solo hago mi trabajo esperando que haya respeto. Haré lo que me toca. Agradezco sus bendiciones.

@EduardoMoncad @ILASColumbia @Columbia @BarnardCollege @TeachersCollege Congrats Eduardo!

I am honored and thrilled to take on this new role as Director of the Institute of Latin American Studies (@ILASColumbia). @Columbia @BarnardCollege @TeachersCollege

Presenting my job market paper this week at the @Epsanet_org conference in Madrid: When Criminals Help the State: Winning Hearts and Minds through Public Services. I’ll be on the academic job market this fall, and I'm excited to share and discuss my work. Come and say hi!

This new working paper argues that female economics PhD students benefit tremendously from having female economics faculty around. How do they back up this claim? They look at the timing of sabbatical leaves. When female professors go on leave, it decreases third-year female Ph.D. students’ likelihood of publishing papers and securing academic positions. Male Ph.D. students in the same cohort benefit from this absence, seeing an increase in their publishing and placement prospects. Their estimates imply that "one additional female senior professor in each top-50 economics department would close one-third of the gender gap in representation among assistant professors at top-25 schools."

En países como México, los cárteles dejan mensajes escritos junto a sus víctimas porque esperan que el mensaje sea multiplicado al ser publicado en medios. Por eso los medios Mexicanos acordaron no publicar esos textos para no visibilizar el mensaje de estos grupos. 2/2

@elespectador debe pensar en las consecuencias de diseminar los mensajes que grupos criminales dejan en sus escenas de crimen. 1/2

My theory suggests that criminal groups are more likely to facilitate state service provision when the social capital they gain helps insulate them from state enforcement and financial constraints. Looking forward to the discussion. (3/3)

In this chapter, I draw on qualitative interviews with gang leaders and street-level bureaucrats in Medellín, Colombia, to develop a theory on why some criminal groups choose to help state actors in the areas they govern. (2/3)

Excited to present the second chapter of my dissertation at @ceu in this upcoming public lecture! events.ceu.edu/2025-03-11/why…🧵(1/3)
