No our department is healthy and actually makes money for the UU. Because of the internationalization in balance act.

Dutch track only which means some 25 to 35% less students, which probably means some 25 t 35% fewer FTEs

@utrechtuniversity.bsky.social just decided to shut down the English-taught BSc in Economics from 2029. The executive board did this entirely in secret, no faculty consultation. We found out after the deal was done. This will have massive consequences for jobs at the dept.

My department (Utrecht School of Economics in NL πŸ‡³πŸ‡±) is hiring 2 full professors. One in Macro and one in Applied Microeconometrics (don't let the fancy title in the opening fool you).
I'm not on either committee, but happy to answer questions.

Next week the Dutch parliament will vote to cut 2 billions on education and research.
Some Dutch economists write here that the economic case for these cuts is incomprehensible.
Of course they are right. These cuts are only understandable in the context of a vendetta.

Robust Estimation of Private Business Wealth*
Job Market Paper
Simon J. Toussaint†
November 14, 2024
[Most recent version here]
Abstract
Estimating the market value of private businesses is essential for understanding both aggregate firm dynamics and top wealth
inequality, yet these values are inherently unobservable. This paper introduces an econometric approach that treats the gap
between true market values and initial estimates as measurement error. I employ time-series restrictions on these errors as
moment conditions within a GMM framework, and use the fitted values from these estimations as error-free estimates of
private business wealth and capital stocks. Applying this method to Dutch administrative data linking the universe of firms
to their owners, I find that aggregate private business wealth increases by 30% of GDP initially, and is more stable than the
unadjusted series. Top 1% and 0.1% wealth shares increase by 3–5 percentage points, peaking at 38% and 20%, respectively.
Adjusted returns to firm wealth exhibit a steeper gradient across the wealth distribution than unadjusted returns, consistent
with models of return heterogeneity.

πŸ“― Job Market Paper Alert πŸ“―

Private businesses make up 50% of sales & profits and are the main wealth component of the wealthiest households. So, what is their value? Well, that's difficult, since they're not listed: their value is unobservable by definition!

(First) afterthought on the cancelling of our protest #WOinActie.

The reason the protest got cancelled was because of alleged threats by a pro-palestinian group that wanted to "hijack" the demonstration and was ready to use violence. >

#econsky, a methodological question: I need to create an indicator about workers' mental health, based on register data covering prescriptions, diagnoses and doctor contacts. Most of these items are right skewed, with excess zeros. What is a common/best way to do this?
