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, ...).

We present a practical guide to these methods for empirical researchers, along with an easy-to-use Stata package that implements them:

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.

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 😂

Free research idea: The borders of the Holy Roman Empire around 1200 and university choice in the 21st century.

(Insert hand-waving about network effects.)

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?

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?

Second reason I could think of is that some fields (definitely teaching, maybe law) are still state-specific. E.g., with a teaching degree from Niedersachsen it is harder to become a teacher in Sachsen, etc. If people want to move back closer to home, this may lead to home-state bias.

Could it be partly that students often get heavily subsidised regional travel tickets from their universities, which only work within the respective state, and that students use these to visit home on weekends etc? May not be so relevant anymore with the 49-Euro ticket, but maybe in the past...

One of my favourite examples was when he bundled together the German Greens and the AfD as "those types of parties", in the context of support for Ukraine.

That looks great, thank you!

I agree! I was just describing an example of the type of problem that normal people without much programming experience outside Matlab and Stata run into.

Specifically, one thing I struggled to find good info on was how to organise code across files. In Matlab, you have a main script that calls a bunch of functions that are defined in separate files. I couldn't find much about how best to do this in Julia, maybe because it's obvious to programmers.

Much of the material online, even the Econ focussed stuff, spends a lot of time on "computer science", which I think scares many people. I think more people would be persuaded by simple side-by-side code examples, similar to stata2r.github.io

I haven't used it in a while, but I think the "software engineering" overheads are still the main factor stopping people from switching. I enjoy tinkering with software, but most people just want to be able to open a program, type stuff in, and get stuff out. Maybe more templates would help.

Great idea! Would love to be added.

I see this has already been answered, but more generally this page allows you to search for starter packs.

Oh! I didn't realise that it's completely open. Well in that case, we can all look forward to reading the first Econ WPs about this very soon.

The poor data science people at Bluesky will be absolutely swamped by emails from Network Economists asking for data for years to come.

Okay, not just me then. That's annoying.
