🚨New Stata Journal article 🚨

Economists working with experimental data write their own functions for testing axioms of revealed preference (RP). Most economists work in Stata, and up until now there has been no unified package with the most basic tools of RP.

@akib_kn @DemetryYoustina Nice!! Agreed, it’s pretty cool work!

Very excited to have more than 30 researchers joining us for Växjö’s Replication Games today! 🤩 @I4Replication @linneuni

No author has shaped my worldview more than Nassim Taleb (@nntaleb).

I stumbled on The Black Swan eight years ago, then inhaled the rest of the Incerto.

I've increasingly come to appreciate the importance of its ideas to prolonging the human story.

Was an honour to speak with Nassim on the podcast.

Hard to summarise our conversation, but the timestamps below capture the gist.

Enjoy!

Timestamps:
(0:00:55) - Heuristics for knowing when you're in Mediocristan versus Extremistan.
(0:06:06) - Are certain tail exponents intrinsic?
(0:10:30) - Why hasn't Universa's tail hedging strategy now been fully priced in?
(0:11:52) - Does the power law distribution of startup returns mean VCs should concentrate their bets, or spray and pray?
(0:15:20) - Nassim's 30-minute take on the field of behavioural economics.
(0:48:57) - Nassim's 20-minute take on superforecasting.
(1:11:03) - The Precautionary Principle and AI.
(1:17:28) - What are LLMs doing?
(1:23:10) - War, violence, & "the empirical mean is not the real mean".
(1:39:17) - Covid, & how Western governments think about tail risk.
(1:43:38) - What's the most important thing people in social science get wrong about correlation?
(1:52:58) - How does Nassim explain the perspicacity of the Russian school of probability?
(1:55:56) - Why doesn't Hayek's knowledge argument extend to prediction markets?
(1:58:26) - If mean absolute deviation is a better measure than standard deviation, why has the latter become commonplace?
(2:01:09) - Nassim's next book, and what he's up to at the moment.

@akib_kn Haha! 🤣 That one got me. I’m stumped. Maybe we’ll compete over fashion style or (natural) scent? A comeback for reciting Quran/Bible/Shakespeare? JMC flyouts should include clear sword fighting instructions

[Marcos Demetry @MarcosDemetry]

The #NotebookLM is pretty cool for summarising & disseminating research!

I fed it my Schelling segregation WP and it produced a 6 min podcast (first 2 min here). I wish one could tweak the detail level (I want more) and actively include/exclude sections. Still cool! @GoogleAI

[Marcos Demetry @MarcosDemetry]

@akib_kn Also, the cost of making things sound cool is approaching zero, so we’ll be flooded with this stuff. Everyone will have their own audio-visual sensory experience describing their research, adapted to each listener’s interests/capabilities. We’ll “vibe”, not read, other’s research

[Marcos Demetry @MarcosDemetry]

@akib_kn Insane, right?? It’s also impressive how quickly we/I become accustomed to tools that just recently would have been considered sci-fi.

[Marcos Demetry @MarcosDemetry]

“Why Machines Learn” by @anilananth is the opposite of clickbait. No buzzwords, just beautiful concepts explained pedagogically with mathematical equations, text, examples and illustrations. The history and current state of ML is fascinating! Soon on Ceres Books 📚

[Marcos Demetry @MarcosDemetry]

@GabrielOrp1 Congrats Gabriel!! 🥳

What a pleasure to attend #EALE2024 in Bergen! Met old friends, made new friends and presented a poster! Thanks @eale_sbe & @NHHEcon

Tell me which books you think I'd enjoy based off of this list—I'd love to find some more exciting books! Go in, give it a like, and join me on this journey 📚

[Marcos Demetry @MarcosDemetry]

I started sharing some of my favourite books on Ceres Books: https://t.co/b81HCkZ4I1. There's everything from astrophysics, complexity theory, to segregation and social psychology. These aren't book recs per se, just highlighting what I enjoy. Check it out! #Reading #NonFiction

[Marcos Demetry @MarcosDemetry]

@SchultenSimon Excellent tips! From now on, whatever font size I choose, I'll just assume it's too small and make it bigger :)

[Marcos Demetry @MarcosDemetry]

Any tips for making a good conference poster?? There’s so much I want to explain, but so little space 😅 *Tweets with pics are more entertaining, I believe, so here’s me working from home. #EconTwitter

[Marcos Demetry @MarcosDemetry]

@LWallossek Fantastic tips! I was recommended this nice template (https://t.co/G37Dvqli1T), which I liked specifically because of the boxes! I'll make it portrait, 2 cols only and less text.

[Marcos Demetry @MarcosDemetry]

@akib_kn Great tip! That’s a good starting point for me now 🌟

[Marcos Demetry @MarcosDemetry]

@annahasselqvist Fantastic tips! I thought of having a draft of the paper with me, but printed out slides with additional results/robustness etc is much more practical for people on-the-go. I’ll do so!
