The article examines income inequality in Italy from 1989 to 2016 by looking at how different sources of income are distributed among the population. The researchers found that the connection between how income is earned (like from work or investments) and how it is distributed among people has been getting weaker over time in Italy. This means that changes in how much money comes from different sources are having less of an impact on income inequality. Italy is also becoming a society where people have income from multiple sources. The researchers suggest that a simple way for policymakers to reduce income inequality in the long term is to consider how different sources of income are distributed.
