We study the relationship between per-capita income and income inequality with a heterogeneous panel co-integration approach. We extend previous studies in two respects: first, we compile a more extensive data set for 87 countries over 26-58 years and consider measures for both pre-tax and post-tax income inequality; second, we take into account country heterogeneity rather than focussing on average panel estimates alone.
We find a statistically significant positive group-mean based relationship using pre-tax income inequality, but no such relationship for post-tax income inequality. However, we find estimates on the country level to be very heterogeneous in both cases. Both empirical findings invite further research: by laying out relevant empirical patterns using a robust methodology, our contribution is meant as a vantage point for further theoretical work geared towards understanding the mechanisms underlying these findings.
