First week of teaching in Paris Sorbonne. Of course, my first lecture is postponed because today is strike day and getting to the Uni might be nearly impossible for staff & students. The experience wouldn't be french otherwise. 😅

I am very happy to share that I am joining the Sorbonne University as an Econ Prof.

I am extremely grateful to everyone that made this possible, above all my parents.

💡These findings cast a new light on the seemingly puzzling result that, in the aggregate, large changes in beliefs about inequality often do not translate into changes in demand for redistribution.

🤔 How do beliefs and prefs affect support for the 99% initiative?

1.Those with social prefs are more supportive of the 99%
2.The shock in beliefs does not affect avg support for the 99%.
3.Heterogeneity 🚨! The shock has a large effect on the support of the (richer) inequality averse.

Julien Senn @sennjulien.bsky.social · May 23

Can these misperceptions be corrected? Yes 😃
Does updating depend on preferences? No 😮

Using an information intervention (a downward shock in beliefs for almost everyone), we show that most subjects update their beliefs downwards, independent of preference types.

Julien Senn @sennjulien.bsky.social · May 23

🤔How do these subjects perceive inequality, and do these perceptions depend on preferences?

We contacted them months later and find that
i) most vastly overestimate inequality
ii) these misperceptions are largely independent of preferences.

Julien Senn @sennjulien.bsky.social · May 23

We first elicit the distributional preferences of a sample broadly representative of the Swiss voting population.

Three distinct behavioral types coexist: inequality averse, altruistic, and selfish subjects.

This is consistent with our previous work (tinyurl.com/44p7ujjn)

Julien Senn @sennjulien.bsky.social · May 23

Using a staggered experiment, we explore the joint role of distributive preferences and beliefs about inequality for support for the 99% initiative—a highly redistributive policy proposal on which Swiss citizens voted in 2021.

I noticed this too that universities and PIs are increasingly trying to exploit their market power, and no one seems to stop them. In other countries non-fulltime PhD and postdoctoral positions are very uncommon, as far as I know.

Caleb Ward @calebw.bsky.social · May 12

Keeping one eye on academic jobs in Germany, I'm seeing more 50–75% positions, where salary & work hrs are both reduced. I'm even seeing 50%-time, 3-year doctoral jobs, where you're expected to write a dissertation in <20hrs/week in 3 years (while supporting a research team). 👎

I don't think this is only a german problem. The fact that juniors have to so extremely rely on advisor(s) for all the important steps in their career is in my view one of the biggest issues in academia.

“There is far too much power in the hands of professors in the German system,” says @leising.bsky.social.

My latest @nature.com story digs into efforts to tackle the entrenched structural heirarchy that enables academic bullies.

Can Germany rein in its academic bullying problem?

Researchers and administrators are exploring ways to restructure a rigid hierarchy that can breed power abuses.

I don't think this is necessarily a german problem and I have always seen this as the biggest issue in academia. Juniors are way too reliant on advisor(s), at all levels.

The fear among academics and lawyers now talking on the record on just about any topic that involves the federal government or the White House is really extraordinary and worrisome, and getting worse, it seems to me, every week. Dissent by an establishment figures becoming verboten in the US

Monstrously destructive, incoherent, ill-informed tariffs based on fabrications, imagined wrongs, discredited theories and ignorance of decades of evidence. And the real tragedy is that they will hurt working Americans more than anyone else.
