Id like to run a special issue of a social science journal on "Calling Bullshit" where people can just go on a full on rant (anonymously if they like) and rip well established ideas to shreds. Zero requirements to be balanced or polite or have any respect for pompous senior professors.

Could be a useful way to publish on topics that you suspect might get unflattering results!

New submission format at SBE:
“Replications as Registered Reports”

You can get "in-principle acceptance" before data collection even begins; final paper gets published regardless the results, if the study is conducted rigorously.

I'm a few minutes behind the live call, but here's my Q4 Tesla earnings call "live thread"!

We start out with Elon announcing that Tesla's mission has changed to "Amazing Abundance," which represents a pivot from the "Sustainable Abundance" tagline he announced last year.

The reality is that 2024 was a fundamental test of the moral character of the nation and we failed spectacularly. We’re living with the consequences now. Maybe we improve. I hope so.

The one thing that is growing extremely fast is the wealth of the top billionaires:

The top 0.00001% used to own the equivalent of 3% of national income in wealth in 2010

Now they own the equivalent of 12% of national income!

I'm extending research we have been doing on marginal undersized poor performance firms, looking at their labour productivity.

The length of the long tail of poor performance firms in the UK is well known but still striking.

But the depth of that tail is a real shocker. Their labour ....

From buying glass breakers to opting for new cars, Tesla owners are having to go to great lengths to deal with a problem most had never imagined: being unable to open malfunctioning doors in the electric vehicle.

Tesla drivers buying escape tools and new cars to avoid getting trapped inside

Addressing Tesla's malfunctioning doors has gained urgency in the U.S. after numerous incidents in which people were severely injured or died after being unable to escape vehicles.

This is reminiscent of previous findings of a negative relationship between Self-Employment and GDP per capita:

Henrekson & Sanandaji:
doi.org/10.1073/pnas...

Percent self-employed on the vertical axis, log of per capita income on the horizontal axis. There is clearly a negative relationship.

The share of female entrepreneurs first rises, then falls with national income

In higher-income countries, female entrepreneurs tend to have smaller firms in low-complexity sectors (e.g. due to discrimination), weakening the gains from female entrepreneurship

These two time series do NOT have the same degree of persistence!

#EconSky
#EntrepreneurialEcosystems

Fig. 3. van Dijk et al. (2025)’s indicator of persistence is unable to distinguish between extreme positive persistence (left) and extreme negative persistence (right).
Notes: Measuring persistence using a first-order autoregressive model (like our eq. (4), but with only one first-order lag), we get
ρ
persistence on the left, and
ρ
= 0.8 for the case of positive
= 1.00 for the case of negative persistence on the right. Van Dijk et al. (2025)’s indicator of “persistence” calculates the same score of -
0.3513642 for both the left and the right. R code is in the Online Supplementary Materials.
