Good News! @nytimes says we are making progress on housing supply! (Just don’t account for… the passage of time.)

I recall someone saying on the old site that most Chromebooks provided to school children have as a default setting something that does not allow them to create folders even if they wanted to. But I could not find info about this in a quick Google search.

Meant to say "add what @kaseybuckles.bsky.social said."

Thomas Fujiwara @thomasfujiwara.bsky.social · Nov 27

I think there's a general generational divide in caring about the "keep the files organized" part. Probably not true for work colleagues/researchers, but young people don't even use folders: it's "leave it all in Google Drive" and use the search function to find things.

Acho que tem um “atalho” (acho q virando a esquerda logo quando vc entra no duty free, e passando pelos caixas). Voce nao evita o duty free como um todo, mas pelo menos nao precisa atravessar ele inteiro como o aeroporto quer que voce faca.

Actually, the share for 2026 is 12.16%. The graph says econ was the most declared major but there’s 2 computer science majors (BSE and AB), which combined would be larger than econ.

184 members of the Class of 2026 declared Economics. We broke down Declaration Day.

Ahead of Declaration Day for the Class of 2026, the ‘Prince’ broke down the most popular majors. For the first time since at least 2017, Economics is the most popular major, declared by 12.16 percent ...

My contribution to this exciting initiative was an "almost entirely successful" robustness replication of López-Moctezuma, Wantchekon, Rubenson, @thomasfujiwara.bsky.social, and Pe Lero (AJPS 2022).

Thanks to @i4replication.bsky.social for their incredible efforts!

JPAL has a page (with links to official documents) on "intake and consent." Perhaps it's not exactly the same issue but it's related since they go over under what circumstances IRBs should waive informed consent.

I think Neil and Arthur are not on BlueSky, BTW.

I know there was this older literature and the puzzling result in this paper , but I don’t much about more recent work.

Thanks!

Thanks! A quick question: did the older version from years ago also give you the economist you disagreed with the most too? I remember that but it was so many years ago...
