I think the effects are strongest on knowledge qs. I thought of the idea that (through earlier participation) christallized attitudes have lower variance.

So I discovered a whole field on panel conditioning. Thought about something in relation to the LISS panel, but there is so much on it already. I love (too much?) to dig into something new.

I would have to take a closer look with this in mind

Looking forward to presenting our @equalstrength.bsky.social project in Oxford tomorrow, a cross-national and cross-domain field experiment on ethnic discrimination in 9 European countries. This was truly a collective effort, and we're proud to present findings, after so many months in the field!

Wage returns to human capital resulting from an extra year of primary school: Evidence from Egypt In this paper, we examine the wage returns to an extra year of primary school using a policy reform in Egypt, which reduced compulsory primary schooli…

Policy reforms to *reduce* educational attainment were detrimental for disadvantaged boys, in Egypt. www.sciencedirect.com/science/arti...

Although the 1 million mentioned on Wikipedia may be a bit much. Hundreds of thousands at least. Talking about information silos.

In foggy Nürnberg, I’m visiting the place of the “Reichsparteilage” of Nazi Germany. Where, in the 1930s, an authoritarian leader spoke for close to a million people (Nuremberg Rallies). Authoritarianism is not the solution.

I also like the plea for looking more into the great equalizer hypothesis in comparative research. Luckily we’ve some of that with @aforster.bsky.social 😉. We showed that the heterogeneity in college effects is rather small, and we differentiated between fair and unfair sources of college education

"We conclude that for higher education to serve as a true equalizer, it must become both less selective and more accessible to students from disadvantaged backgrounds."

My simulations got a bit snowed under because of reviewer and editorial requests - it’s an appendix now - I thought this may have been the most important finding of my paper (that it’s about changing associations that educational expansion causes rather than compositional change).

Although an important difference is that I don’t have a causal effect of schooling in my macro comparisons. @kbkarlson.bsky.social. Great paper!

I think the results fit with my findings in my ASR paper; the simple interaction doesn’t explain why educational expansion is associated with declining OD associations. In my words: with societal change (e.g. expansion) the *parameters* change, not simply the group sizes that have different OD links

This paper shows that the interaction between social origin (parental income eg) and education predicting destination (child’s income) is no longer negative once one holds constant for unobservables (using IV methods using local presence of colleges a.o.). >

Three guys in the woods from the back

My dad, my brother and me. My daughter, who took the pic, says we have the same skeleton.

Link is dead?

Ja got it. Een kleine vergissing en een extra tijd van de lengte Groningen Rotterdam ofzo

Ha nee! Gelukkig had ik de rechtbank al een keer bekeken - ik kom er elk jaar. Maar nu nog het grote plein voor de massabijeenkomsten en het bijbehorende documentatiecentrum.

2.5 uur extra in de trein pff

I was going to Nürnberg @nsinternational.com

The 13:22 train from Düsseldorf platform 16 did not go the same route as my ticket says. What’s this. Now I’m in Stuttgart.

Hopping on the train to Nürnberg from beautiful Amsterdam ❤️
