FAZ and the council are traditionally the home of German ordoliberal orthodoxy. So far, so expected on c).

But that she is from the US and offers an international perspective was *the point*, and is still needed. Germany's economic weakness in part comes from its insular economic debates.

New WP: β€œUniversity as a Melting Pot: Long-term Effects of Internationalization”

Debates on international students often focus on capacity constraints, funding, or competition.

In the paper, I show that the main effects of internationalization on natives are not academic or economic, but social.

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.

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".

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)

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

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!
