Admin data tends to be good/more accurate for some things, but not uniformly. Its clearly wrong that admin data is always better for everything. It also doesn’t have to be fraud - there’s fairly well documented errors in education variables in German social security records, for example.

I agree re the opportunity - we are lucky and have three replacements posts that we’re currently recruiting for - interestingly we were also lucky in 2020, when we had more. It makes a big difference.

Not sure about the “missing” bit - UK institutions have financial issues, Netherlands have government cuts etc. I’d say we’re well aware that it’s a buyers market at the moment, but lots of places have no headroom to hire.

We have a bit on that in section 4.2, we look at spillovers to other supermarkets nearby and other crimes - there’s not a lot of evidence on spillovers. The other bit to keep in mind - shoplifting increases everywhere over the time period - just a lot less strongly at Tesco than elsewhere.

This started out as Wednesday's undergrad dissertation. Supervising undergrad dissertations has always been one of the aspects of the job I like the most, so it’s particularly nice to see outcomes such as this! Very fun project to do as well!

Hatten wir auch mal - 17-18 damit die Leute hinterher in den pub konnten. Dann hatten ein paar von uns Kinder. Seitdem ist es 13:30-14:30 (UK hat allerdings bessere Kinderbetreuungszeiten, wenn auch sauteuer, speziell für <4-Jährige)

I wouldn't count on that given that numbers are already contracting across many subjects. My own and neighbouring disciplines are probably fine, but that's far from uniform...

If the school FE captures things like peers, I would expect both to be “big”. My prior would be that the family FE is slightly bigger, but I’d be very surprised if the school FE wasn’t sizeable.

Not a specialist on automotive industries - but I’ve got a feeling that sick leave rules might not be the main reason for their current crisis…

Yeah, we switched all econometrics etc. teaching to R now (except for one module teaching python). ChatGPT is also very good at coding in R so switching individually has much lower setup costs now relative to when you switched.

Usually the turnout is decisive - over the last years there were very few ballots where the yes vote was below 50% and the turnout was over 50% - see eg figure 3 in here arxiv.org/pdf/2401.05183

I suppose every bread that isn't rock-hard and stale is somewhat moist... Potentially she misspoke and meant "soggy"...

Nils Braakmann @nilsbraakmann.bsky.social · 12/12/2024

Quesadillas tend to be toasted on the outside though? I guess the inside is moist with the melted cheese, but if the outside is moist you have too much guac and salsa on top for too long.

Nils Braakmann @nilsbraakmann.bsky.social · 12/12/2024

That qualifies as a sandwich though, no? It’s basically cheese in between “bread”.

Nils Braakmann @nilsbraakmann.bsky.social · 06/12/2024

that some of the members who voted for industrial action actually won't be employed at a university anymore by the time a strike comes around (e.g., PGRs, casual staff). I mean you CAN call a strike under these circumstances but I doubt that it would have a big impact... 2/2

020

Nils Braakmann @nilsbraakmann.bsky.social · 06/12/2024

I mean given the numbers they can be reasonably sure that 14% of their members are prepared to take industrial action (assuming that not returning ballots isn't exactly a sign of high mobilisation). There might be a few more who voted against and are willing to strike, but there's also a chance 1/2

110

Nils Braakmann @nilsbraakmann.bsky.social · 05/12/2024

With my labour economist hat on - I think it would be brave for any union to actually call for strikes given that majority and that turnout…

Nils Braakmann @nilsbraakmann.bsky.social · 02/12/2024

Plus, I don't think anyone stops anyone from saying "look, I'm only going to coauthor with you if you pay me amount X". I mean it's not going to work, but if they hate unpaid projects anyway, it's not as if they're going to lose out on anything they value...
