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...

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

Vinyl skills: 1. What is vinyl? 2. It has two sides. 3. Can place the needle right before the bridge of Karma Police.

Vibe coding may be hazardous to open source

Our paper with @gaborbekes.bsky.social @julianhinz.bsky.social and Aaron Lohmann is/was on top of HN. 15 minutes, I guess.

My favorite German veterinarian jargon: tier spezifisches Eigengeruch I keep repeating it to my dog.

Vibe coding kills open source. Our most direct title yet. @koren.mk @julianhi.nz @aaron-lohmann.bsky.social Theory paper with numbers and policy recs. First at arxiv.org/abs/2601.15494 Comments welcome. @ceu-economics.bsky.social @kiel.institute

Words you only hear in a vibe coding session: "Now let me deploy and test"

Hungarians will understand what this is for.

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/...)

This morning I heard my son hum Nirvana in the bathroom. Not sure if I should be proud or worried.

Super stoked about Krasznahorkai's Nobel Prize. A beautiful interview with him from a couple years ago: www.guardian.co.uk/books/2012/a...

When you start your commit message with bigfux: instead of bugfix: you can be sure it was a major bug.

Great summary of research on AI coding agents. www.cerbos.dev/blog/product...

How to make sure you ran reproduce all steps of your research months later? We demoed our CLI tool bead.zip that saves code and data together at RSECon at Warwick. Slides bead.zip/rsecon25

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.)

Always excited to hear Elhanan Helpman. If you're in Vienna, come by. events.ceu.edu/2025-05-07/p...

Why I love OneDrive, part 78. My local folder is called /Users/koren/OneDrive\ -\ Central\ European\ University\ \(CEU\ GmbH\ Hungarian\ Branch\ Office\)/ Luckily, I can symlink.

Austrian Airlines is pitching Budapest for me. I mean, I love the city. But as long as this is how well AI understands us, I feel safe.

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".

Ceci n’est pas une espresso machine.

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.

New level unlocked: typing an email, three letters into a word in the second sentence, get distracted, then go back and try to figure out what words begin with those three letters. #adhdlife

Why did we develop Kezdi.jl and what can you do with it? Watch my presentation at JuliaCon in Eindhoven. #juliacon #juliasky #econsky youtu.be/JklbLwgePis?... docs.koren.dev/Kezdi.jl/dev/

The fact that i’ve been listening to Bob Dylan, Joan Baez, Donovan and John Lennon these past days doesn’t mean I won’t defend capitalism in a degrowth debate. koren.dev/events/2025-... I like to keep my music out of my science.

Why not just set up a national firewall? Blocking terms like, you know, Tiananmen Square.

This the kind of music vinyl is invented for. Go watch the Bob Dylan biopic. Timothée Chalamet is great. #nowspinning

Librarians are going to save us 👏

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.

I am reading Robert Fisk's magnum opus about Lebanon (en.wikipedia.org/wiki/Pity_th...) and let me tell you, Trump's ethnic cleansing plan is not a good idea.

I bought some Nvidia stock. The news is not that AI is a hype. It’s that LLMs are a commodity in abundant supply. What product is complementary to LLMs? Even for inference, you need quite a bit of GPU compute.

Rebalanced the tonearm of my player. I just followed the step-by-step instructions of the manufacturer, but it helps that I now understand why it matters.

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 rebuilt my website with a new structure and design. koren.mk ― papers and CV ― most economists will stop here └ koren.dev ― courses and software ― useful for students └ codedthinking.com ― blog ― why I am doing this #econsky

Gonna be awesome, join us if in #Vienna on 10 January. www.meetup.com/vienna-data-...

But, there is hope. Some enthusiasts, in the very best sense of the word, like @koren.mk, are developing packages to make the transition from Stata to Julia easy. codedthinking.github.io/Kezdi.jl/sta...
