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!

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.
