Updated this chart with the newest Gemini. It shows the rapid progress in AI over less than two years: costs for GPT-4 class models has dropped 99.7% and even the most advanced models (beating PhDs at the GPQA) are still 82% cheaper than GPT-4. Probably not worth betting on this trend ending soon.

Love what you have done with that graph

Been using @zotero.org for bib management for many years, but what is most remarkable about this project is how it keeps improving. Its pdf reader now beats anything else I've used, and v7 added the Smart Reference Popup that allow me to peak at a figure/table/reference without leaving the text.

Ever wonder why in finance we refer to market-wide risk as "systematic" instead of "systemic"? Purely from the standpoint of dictionary definitions, “systemic” (affecting an entire system) might appear more intuitive for market-wide risk than “systematic” (done according to a system or plan).

Why do large Swedish companies file for Chapter 11 in the US? And what does it tell us about reform opportunities in EU insolvency law? (Hint: ch 11 is better; reforms should continue). I discuss the Northvolt filing here: www.hhs.se/sv/houseoffi...

Good idea. Using sentiment analysis @israelsen.bsky.social, eitan goldman and I found that the same corporate financial news is covered differently in the NYT vs WSJ based on corporations’ politics www.sciencedirect.com/science/arti...

Exciting stuff. Competition is good. www.wsj.com/articles/ama...

1/ Does finance benefit society? 📈📉 In a forthcoming Review of Financial Studies paper, @mjha91.bsky.social , Hongyi Liu, and yours truly tackle this question by leveraging large language models to measure sentiments in books spanning centuries and continents. 🧵

How much time passes between when you get the announcement that a new version of Julia is released until you juliaup update? (ICYMI v11.2 is out today)

Pluto is an absolute masterpiece of scientific and educational software. It's like Jupyter notebooks without "rerun all". In fact, it's so good someone wrote a song about it!!! youtu.be/SyloWC8gheM?...

Survey forecasts are not that useful for investing: "How accurate are survey forecasts on the market?" by @jiaenli.bsky.social and coauthors. Link to updated working paper: dx.doi.org/10.2139/ssrn...

First skeet for the first paper as an AP! In *Anatomy of Treasury Market*, we study the drivers of U.S. Treasury yields over the past two decades using a flexible asset demand & supply system (with two amazing coauthors @haonanzhou.bsky.social and @manavchaudhary.bsky.social). Some highlights:

New paper alert! 📢 WFH reshapes the tradeoff between job flexibility and entrepreneurship: fewer startups, esp. women-led. ⚖️ Flexibility at work is now a tradeoff for autonomy. Explore the findings: papers.ssrn.com/sol3/papers.... @yalesom.bsky.social #econ #newbusiness #wfh

Matt Levine's account sure looks like a bot is just advertising his (highly recommended) newsletter with a generated title. Except the "spent" typo through me off. Is it really you @matt-levine.bsky.social ? Will you pass a turing test?

Is Mark Cuban the billionaire with his thumb on the scale on this platform or is it just my feed?

my office/outlook mail server doesn't seem to work this morning, so sorry if you sent me an email, but not sorry I'm having a productive morning

Does anyone know a source for recent data on average GPA by University? #EconSky Best I could find is gradeinflation.com whose data ends in 2016.

🚀 Excited to introduce Jiaen Li, a standout PhD student on the job market this year! Jiaen's work is at the intersection of finance, machine learning, and ideology, and she’s asking a big question about how ideology shape markets. #EconSky #FinSky #EconJMP

I didn't know this market existed, but I guess it makes sense given the stakes involved

Just published: We've used speech data to uncover trends in partisanship at the SEC and Federal Reserve. Interesting find: Partisanship at the SEC peaked in the last decade, evident in language and voting behavior. Dive into the nuances with our paper! academic.oup.com/rfs/article/...

"We will not allow Hamas to hide behind Palestinian civilians while it murders our civilians. We will never target civilians, as they are not our enemy, but if civilians in Gaza are killed while being used as human shields, Hamas will have murdered them as well." www.economist.com/by-invitatio...

Important work. This floored me: "In the United States, 5 percent of all children spend some time in foster care and 37 percent are involved in a maltreatment investigation by a child protective services agency by age 18."

Back to the Missouri Botanical Gardens today and this glossy invasive species has spread like wild 🔥

What is the most interesting question in your subfield that PhD candidates could consider pursuing? I’ll start:

Are there ads on bsky? If not, who is going to pay for this party? 📉📈

So when we will be able to estimate twitter following - bsky following ≈ bots?

I am very fortunate to be working with smart and motivated coauthors. Like a great multiplier on my learning.

Call for papers for what might be the best finance conference out there (opinion only of course and disclosure: program committee member) Consistently fantastic papers, discussants, and fun www.uky.edu/financeconfe...

I am really excited to help announce a new book. It is a textbook in Ukrainian on writing math in English. A big effort by an amazing team that hopefully will be useful to students interested in math and science. Please signal-boost! mathematicalenglishUA.org

Did you know that the word "school" comes from the Greek word "scholē", which means "leisure"? Ancient Greeks believed that leisure was essential for learning, and schools were places where people could pursue their intellectual and cultural interests.

Speaking into the void: is there anybody out here ?
