Has anyone ever done a global or regional time series of the Gini coefficient* mapped against the current ideological faction** in power?
The more countries in the time series, the more informative the time series could be (by virtue of a larger sample size).
I'd love to know how strong the (presumably time delayed) correlation is.
* Or the rate of change of the coefficient.
** Along a classical left-right spectrum for simplicity and the existing over-abundance of dichotomic literature.
