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.

Tesla's fourth "Master Plan" tells us nothing about the company's future. But it says plenty about the present.

It has only been two years since Master Plan III. If Tesla’s underlying business was going well, Musk wouldn’t need to ring this bell so often.
