Shifting tax burden to top income earners: what is the best way to reduce inequality?

open access: yesEconomics: Journal Articles, 2019
The authors analyze to what extent and how the tax burden should be shifted towards top income earners in order to reduce income inequality. Starting from Lambert and Aronson (Inequality decomposition analysis and the Gini coefficient revisited 1993) and
