Why don't firms publish pay in their job adverts?

We present the first experimental evidence on how (not) posting wages changes the applicant pool, and whether that gives firms a reason to hide wage info.

Great short thread by my co-author Lukas + link to the full paper👇

Wouldn't even call them side alleys anymore, it's so blatantly obvious when looking at it from a certain distance

But the article says that these buildings do have air conditioning:

"[...] they rely on energy-intensive air conditioning and heating systems to maintain a liveable internal temperature. [...] 'it is very quickly dramatic' if for any reason the air conditioning switches off".

Climate models since the 1970s nailed it—most predicted global warming almost exactly as it happened.

This is surprising to hear -- I wonder if it varies so much on a local level? Here in Rotterdam, everything is communicated very clearly, well in advance, and documented both digitally and on paper. And it works very well in English (I don't speak Dutch either)

For vaccination to be effective, over 90% of kids need to be vaccinated (so diseases can’t spread). The Netherlands doesn’t hit this level for *any* childhood vaccine - and uptake is falling year on year.
In my experience the program is laughably bad. Next government should fix it!

Iets minder jonge kinderen gevaccineerd

Het RIVM meldt in zijn jaarrapportage dat de vaccinatiegraad onder kinderen tot 5 jaar licht lijkt te zijn afgenomen.

Peak Dutch politics:
After three parties (BBB, NSC, VVD) couldn’t agree on who should be immigration minister, they’ve reached a compromise:
there will be three immigration ministers; one from each party

The thing about Europe: it's the actual land of the free now.

Whatever problems Europe has - and it has plenty - it is looking pretty damn good by comparison these days.
