Nice that this paper has been finally published after more than 10 years since the first draft! aeaweb.org/articles?id=10…

🚨 Due to high demand, I created a new (and much improved) version of the Econ Journal Matchmaker. New tool here: …ed75b671.eastus.azurecontainerapps.io #EconTwitter Please help spread the word by reposting. 🙏 More details below 👇

The results of the research happening in my team @GoogleDeepMind have convinced me that the next era of scientific discovery will be aided by AI agents acting as force multipliers for human ingenuity. That’s why I’m proud to introduce Gemini for Science - a collection of experimental science tools designed to support researchers at every stage of the research process. The tools include: 1️⃣ Literature Insights, built with Google NotebookLM, searches millions of scientific papers to synthesize findings and generate artifacts including data tables, slides, reports, and more. 2️⃣ Hypothesis Generation, built with Co-Scientist, simulates the scientific method via a multi-agent "idea tournament" to generate, debate, and rigorously evaluate research hypotheses. 3️⃣Computational Discovery, built with AlphaEvolve and ERA, is an agentic engine that generates and scores thousands of code variations in parallel, allowing researchers to test modeling approaches in fields like epidemiology in a fraction of the usual time.

I was talking to an economics Assistant Professor today frustrated with the profession. A few years into his job and he's struggling with the last mile of his papers & trying to get them published in the right places. He said it'll get better. The problem: he's only partly right.

I’m really excited about this paper! Some of my work has pointed out problems in empirical work, but this one is all about new 🔧s. If you (or your referees) want to know about the mechanisms by which a treatment affects an outcome, you may be interested. A 🧵.

I coded up an open-source, not-for-profit AI paper reviewer that rivals the performance of @reviewer3com, @RefineInk, and Stanford Agentic Reviewer (according to @GeminiApp). Costs <$2! Live @ coarse.ink. Plug in paper, @OpenRouter key, and email. #econtwitter.

found something rather baffling when researching my column this week… I wanted to see if there was any evidence that AI tools were helping economists to make their research more readable. So I analysed the text of NBER working paper abstracts…

Social scientists working with materials requiring digitization can only study what machines can read. In practice, that means printed Latin-script documents from well-funded archives. In a new working paper, I show that Vision Language Models used zero-shot outperform every existing OCR system across every script evaluated, and I propose a pipeline for deploying them on new collections. I apply it to six archival collections spanning 1.8 million pages across six countries for under $1,900.

How did the US transform from an agricultural economy to the frontier in science and innovation? A new paper published in Research Policy by a team of researchers at the @HarvardGrwthLab and @CSHVienna shows that this process was not gradual but prompted by abrupt changes clustered in the early 1920s. It was driven by the creation of the industrial research lab, which fostered large-scale, science-based, team-oriented invention. The findings suggest that new technologies, such as AI-powered digital collaboration tools, could play a similar role today by reducing coordination costs and potentially reshaping how collective invention is organized.

1/ Today I’m excited to share an updated paper with my colleague Friedrich Geiecke 👇👇👇 We develop an open-source platform to conduct high-quality qualitative interviews using LLMs, including voice interviews. Interviews can run GPT, Gemini, Claude, and open-weight LLMs.

Second-best project management skill I've created: Every week, for each of about 10 research projects, I built an automated skill where Claude Code pulls and integrates: -the transcripts of all meetings - all project-related emails - all discussions in the project WhatsApp groups - all new and existing documents (most of which either live in a folder of Markdown files or in a collaborative Google Doc with multiple tabs for many purposes) - any Overleaf or Tex files Then it automatically generates a 3-page project overview covering - strategic overview with a reminder of long run objectives - critical success, factor factors and operational imperatives over the next two weeks and few months - a priority to-do list for every member of the team for that week It then creates a weekly summary of the recent week's most recent discussions and activities and pastes it to a second tab, giving us a detailed documentation of all the decisions we made and everything we discussed that week (and the weekly summary for every previous week lives below that--so we have a project memory of every major decision and discussion) My next step is for it to populate everybody's calendars or reminders system with their to-do list for the week. Yes, I could try to get four different professors from different universities (for each project) and four different research assistants (for each project)to all work on the same software like Slack. Lots of organizations do this. But since they all have their own special processes and programs, this harmonizes everything. I’m training it to create a tutorial and example system for others to copy and adapt this for themselves. All part of “Claude Blattman”. Stay tuned for the link. I just need to get it polished over the next couple of weeks.

Longer post to come, but the short answer is I am 120% sold on Claude code. Transformative. I've done MANY project management tasks in the last week, but this is one of the best. A week ago, my unread inbox was 5,600. Hallelujah.

It looks like two of the best people in the profession - @HannoLustig and my dear friend and PhD advisor @RWacziarg - have decided to team up for a new econ @Substack called “The Two Cents”. Their first blog is excellent, very insightful analysis - and I bet it’s only gonna get better. Go read it and subscribe!

In this blog post, @RWacziarg and I explain why the EU's 90bn Euro Ukraine deal in December 2025 was really a bad deal for Europe by moving the EU closer to a half-baked fiscal union. open.substack.com/pub/thetwocent…
