@acdc_342 In my experience, arriving 1 day before works better than 2 for a European conference. For the US, I need at least 3 days

イギリスにConferenceできているんだけど時差ボケで眠い。Conferenceの何日前に来るのが良いんだろう。melatoninでなんとかなる？

@MinoruOsawa Here comes the challenger. But can't deny that yours is more beautiful

Time to compete in the office entrance game

Stanford recently livestreamed a 3.5 hour conference with leading economists (@Susan_Athey , Matt Gentzkow, and @ahall_research , among others) on "Empirical Work in the Age of AI" I turned the whole thing into a readable transcript, separated by talk. You can pass the whole thing to your coding agent to extract exactly what is useful for you. Check it out here!: aieconomist.io/resources/empi…

When experts communicate before reporting, network structure changes the information content of their forecasts, even when they are unbiased and equally precise. - Regular networks minimize distortion. - Star networks maximize it. More here: arxiv.org/abs/2406.13749…

@KobeKyotoTaro Congratulations! I am planning to present in UK on October. If we are lucky, we might be able to get a coffee.

PSA for economists: Beware ChatGPT/Claude for refereeing papers. AI is not good at judging taste or forming reasonable judgement about the importance of results. It’s a bad idea to use as a basis for decision making in refereeing. People who use these tools a lot know this but I wanted to make it more concrete. I did the following experiment. I asked for the optimal prompt to revise an intro for “top 5”, then followed the prompts and went down the rabbit hole of revisions suggested and did a gazillion rounds ending up with something. It was hypercautious, full of hedges, had no flair — and dull as dishwater. But I anticipated that; this was not the experiment. Instead: I went to a fresh version of the same AI (different account) and asked it to judge between the two intros. It judged the original pre-revision far superior. I then asked the AI-2 why its own cloned version, AI-1 did such a horrible job. Answer: Good for: catching logical gaps in proofs, checking whether an argument is internally consistent, identifying missing citations, flagging where a reader might get lost in the formal machinery, rubber-ducking a tricky modeling choice. Bad for: deciding what the paper is about, judging which analogies work, assessing voice, knowing when informality is doing real work, anything that requires taste rather than pattern matching. Ultimate paradox: Was AI-1 or AI-2 right? Both were 100% confident in their judgement and man-splained them to me in great detail😂

Congratulations, John!

Economics is - by a long shot - the most politically balanced academic discipline, according to a LLM study that scored the political skew of academic journal articles. It still leans left-of-center but not hegemonically so like the others (higher score = more left wing)

I know this building. It was a small commercial building. There was a bank, a dry cleaner and a supermarket. I shopped at that super market many times. It was very close to my aunt’s house. Stop bombing Iran. Stop killing innocent civilians. #StopWarOnIran

Today @CollegioCA we have @AlfredGalichon give a talk, plus we have 2 days of his math-econ-code.org masterclass. Coorganized with @HazardYagan

Resonates

Wow. Macro model in @MinkiKim_Econ's JMP suggests rollout of the R21 malaria vaccine would boost Tanzania's long-run GDP by almost 7pp (!!!), mostly through reduced morbidity --> increased human capital acquisition

@KobeKyotoTaro So happy for you! You deserve it, totally.

@KobeKyotoTaro Research fit?

AI and Creative Destruction. Start with the facts. US hiring for software engineers cooled after the 2021 boom. Yet medium-run projections remain strong: Software Developers +15% (2024–2034), while the narrower Computer Programmers −6%. That looks like reallocation within the occupation, not extinction. Short-run softness, medium-run expansion. [1/3]

@KobeKyotoTaro Ah yotaro, congrats! Can't think of someone else deserves more.

@minoru_osawa I didn't know this was a thing!!

京都大学東京オフィスのラウンジ、初めて使ってみたけれど大変すばらしい👏　コンセントと自販機があり、眺望よし。学生さん（卒業生含む）も使えるので、東京駅前で時間がある時にぜひ。 kyoto-u.ac.jp/ja/about/facil…

If you have a prior that Japanese train is always on time.. I can update yours. It's my 3rd time experiencing delay > 1hour. I'll miss my flight tonight.
