Related to 3.: Further improvements in e-learning technology, increasing scalability for the "best" educators and displacing the others?

It says "one of the closest", to be precise.

I don't claim that GDP is a perfect measure of human welfare, but this is incorrect. Curing diabetes would free up resources, both of diabetes patients and the health care system, which would be put to other uses (see broken window fallacy). Otherwise we could increase GDP by giving people diabetes?

Would be interesting to know how much of this was the initial "shock" of the spread of protestantism vs the feedback generated from educated mothers educating their daughters and so on.

I don't think "professionals" is the correct translation of "Beamte" in this case. "Beamte" means civil servants, which in Germany comprises many employees of public institutions (teachers, professors, police officers, administrative officials, ...).

🚨 New Working Paper 🚨

w/ @pdavidboll.bsky.social and @jvoth.bsky.social

Do you run regressions on spatial data? Then keep reading!

We present a guide and Stata package for methods by Müller and Watson (2024 ECTA) to deal with Spatial Unit Roots in Regressions.

Müller and Watson (2024) show that strong spatial dependence ("spatial unit roots") can lead to spurious regression results even with HAC corrections, in a parallel to well-known results from time series. They develop diagnostic tests and a method to remove unit roots. (3/n)

It is well-known that spatial dependence is a problem for inference in regressions that use spatial data. However, standard HAC correction methods are only enough when dependence is not too strong. (2/n)

The hope is for future high speed rail projects to continue in a clockwise fashion back to Old Oak Common, at which point the lines will form a ring, referred to informally in policy circles as the HS25.

P David Boll @pdavidboll.bsky.social · Dec 18

The year is 2047, plans for the new HS6 line from Old Oak Common to Walthamstow have been approved. In Walthamstow, passengers will be able to change to the recently opened HS5 line, which will take them speedily on to Woolwich and Bromley.

Oh for sure, but does that explain the discontinuities at the borders? (Which aren't all that apparent for Bonn)

Yes that kind of thing is what I had in mind. Hadn't appreciated the full scale of the horror of those ads though 😂

P David Boll @pdavidboll.bsky.social · Dec 11

Good point. Last attempt: maybe because the education system is so heavily federalised, universities advertise more intensely to secondary schools in the same state? Or the respective state ministry for education predominantly advertises degrees at unis in their state?

P David Boll @pdavidboll.bsky.social · Dec 11

Oh okay, I didn't know that. So BW and BV unis didn't/don't give students any kind of transport discounts, or only within-city?
