My favorite graph from our paper: the Cone of Adoption.

GenAI is not a machine and shouldn't be modelled as such. Given the range of tasks it can do if properly supervised, it is more like a coworker. We explore the economics of GenAI adoption among knowledge workers in a new paper: koren.mk/publications...

Generative AI is directional: it performs well in some task directions and poorly in others. Knowledge work is directional and endogenous as well: workers can satisfy the same job requirements with di...

I had an AI agent refer to SQLite as "noSQL-like DB." Looks like it was trained on Medium/LinkedIn bullshit but I told it in no uncertain terms that this does not pass with me.

Today I was playing with econometrics (matrices and stuff) as well as relational data modelling (how are different entities related) and realized something. > Econometrics is data modelling without the data. I made a similar point in a talk some years ago (github.com/korenmiklos/...)

I subscribed to Google Gemini and cancelled it within 5 minutes. I wanted to create a Google Form from a survey instrument in Google Doc. Gemini cannot do that. It suggested to go to Google Forms and create one myself, using the Doc as a guide.

I have been working with coding AI agents several hours a day in the past couple of months. You get to know their style. Grok is like Elon Musk. Moving fast and breaking things at 10x speed. Not apologizing either.

For the narrow subset of #econsky people clinging to their Stata and crunching big datasets with @duckdb.org, I have vibe coded a DuckDB extension that reads .dta files. koren.dev/software/ Give it a spin and report issues! (Thanks, @anthropic.com Claude Code and the Python Pandas implementation.)

-- Load a Stata file as a table
SELECT * FROM read_stata_dta('path/to/your/file.dta');

-- Count observations
SELECT COUNT(*) FROM read_stata_dta('data/survey.dta');

-- Filter and aggregate
SELECT
region,
AVG(income) as avg_income,
COUNT(*) as obs_count
FROM read_stata_dta('data/households.dta')
WHERE age >= 18
GROUP BY region;

I see a lot of scripts where the file name encodes some structure. Like analysis_this.do, analysis_that.do and plot_this.do, plot_that.do If you have such a clear structure, you are best served by folders. It just as easy to write "src/analysis/whatever.do" as "src/analysis_whatever.do".

To me this seems similar to the early days of the internet. A promising technology with no product. Once the initial bubble bursts, we may yet see fantastic products leveraging the tech.

One aspect of ADHD is that your attention is either 1 or 0. No in between. The former is thought of as the ADHD superpower ("hyperfocus"), but the latter is often equally helpful. - How can you not care? - Like this.

Fascinating read. Reminds me of the dot-com bubble years (yes, I'm that old), when every party conversion would revolve around how revolutionary the internet is and why we should all invest in IT stock. The explanation of how consumer surplus is going to be captured was not very lucid.

I had a dream about giving a high-profile talk totally unprepared. Like, I had drafts of slides from months ago. The place was packed. I saw Ricardo Reis and Ralph Ossa in the audience. I was in panic. Luckily, neither the mic, nor the projector worked. It was a disaster, but, hey, not my fault.

I routinely get surprised by my own models. Have an intuition, write it down formally, see where the math takes you. Wow. Then try to understand the intuition again. This back and forth is rarely visible in finished papers, where it's only math + intuition. But this is ex post intuition.
