This paper extends previous work that derived a matricial approach to the definition of the Bonferroni index. The present study is devoted to the decomposition of a change over time in the Bonferroni index into two components, one measuring re-ranking and the other the progressivity of income change. An extension is then proposed, based on a generalization of the Bonferroni index. The paper ends with an empirical illustration, based on the EU-SILC database, which analyzes the change in income inequality that was observed in 23 European countries between 2007 and 2010.
