For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.

AI will transform every industry, power every company, and be built by every country.

Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.

The world needs both frontier closed models and frontier open models.

We are excited to host the 14th annual Midwest Health Economics Conference at Indiana University, Bloomington, Sept 26-27. Submit to https://t.co/xtyyZc9eNj by May 1. Tell all your friends in the midwest (both geographically and in spirit)! @EconTony

I applaud that editor. I believe there is a bias in editorial decisions in econ journals in favor of papers that “look hard” to produce. Degree of difficulty should be used to judge gymnastics and figure skating, not scientific contributions.

Did you know DOJ is suing Apple? You did? Okay.

Well, there's a lot of talk comparing the Apple antitrust case to Microsoft back in the day.

What were the effects of the Microsoft lawsuit? There's an important paper you should know 🧵

🚨New @nberpubs with @andrewolenski on major hidden profits in the healthcare sector! Bear with me as I explain how nursing homes are able to hide almost 2/3 of their profits from regulators and the public! I promise it's worth it!

Hi #EconTwitter! 📚

Interested in cutting-edge #econometrics for causal inference and Difference-in-Differences designs?

Don't miss this forthcoming paper in @RevEconStudies by @borusyak, @XJaravel and @jannspiess, who revisit event-study designs with a focus on robust and efficient estimation. 📉

A very interesting read for those looking to deepen their understanding of modern causal analysis.
Don't miss out! 🌟

Why does chatGPT make up fake academic papers?

By now, we know that the chatbot notoriously invents fake academic references. E.g. its answer to the most cited economics paper is completely made-up (see image).

But why? And how does it make them? A THREAD (1/n) 🧵
