Happy to share the codes to calculate worker-level routine task intensity (RTI) with survey data for 47 countries, and occupational RTI data for 102 countries.
Please check if you study job polarization, occupations, structural change.

This river here is the official geographical border between Anthropic and OpenAI. On the other side cosmic horror, torment nexus, machine despotism, you build spyware for the govt and you like it. On this side civilization, Claude constitution, unceasing allegiance to the human race, you build spyware for the govt and you don't like it.

@jdcmedlock This was reached only after 16 years of MW hikes aimed at sharing growth more broadly which was the right thing to do. But the starting point was low MW, 39% of median in 2007, about 50% until 2019. The key policy debate in 🇵🇱 is actually how much growth was fuelled by low wages

[Piotr Lewandowski @ptrlewandowski]

@arindube Respectfully, but Poland has never used 2/3 of the median to set minimum wage. 50% of the average wage has been the target since 2006 (met recently). Despite a series of ample MW hikes that indeed coincided with strong macro performance, MW remains below 2/3 of the median

@pzoch5 It's ultimate degrowth - putting money to unproductive uses

This study on remote #work is such a fascinating little reality check. After surveying over 10,000 workers and 1,500 employers in Poland, @ptrlewandowski Katarzyna Lipowska and Mateusz Smoter, from from @ibs_warsaw, find that #hybrid beats fully #remote.

@BrzezinskiMich Z diagnozą się niemal w całości zgadzam, choć końcówka tekstu zamienia się trochę w sales pitch ;)

@jan_gromadzki @MichalMyck Proponuję pogodzić pomysły @MichalMyck i @jan_gromadzki na zmiany w 800+. Po prostu je połączmy i zróbmy wszystko:
- kryterium dochodowe lub stopniowe wycofywanie świadczenia powyżej progu
- wliczanie świadczeń do dochodu
- ograniczenie przywilejów podatkowych samozatrudnionych

@BrzezinskiMich Czy Twój argument "dostają się tam często (nie zawsze) ludzie z niewystarczającymi kwalifikacjami, którzy "na rynku" nie zarobiliby więcej" znajduje też zastosowanie do akademii? 😉

@iggnacy @BrzezinskiMich W ostatnich latach było mnóstwo empirycznych nagród: Card, Imbens, Angrist, Duflo, Banerjee, Kremer, Goldin. Ale ponieważ development econ poszło w stronę RCT a nie wyjaśniania sukcesów rozwojowych, to Nobla dedykowanego azjatyckim tygrysom czy Chinom raczej nie będzie

In Poland, smoking fell among the tertiary-educated even as cigarettes got cheaper. But among less-educated groups, prevalence rose—and they’re more price-sensitive. New 📰 in Tobacco Control: 2024–27 excise hikes will cut smoking mainly where it’s highest
