Growing wealth disparities can have corrosive effects on equality of opportunity when they crystallise over time and turn into persistent disparities across generations. This column uses newly assembled data from Italian inheritance tax records to show that the wealth share of the top 1% (half a million individuals) increased from 16% in 1995 to 22% in 2016, and the share accruing to the top 0.01% (the richest 5,000 adults) almost tripled from 1.8% to 5%.  In contrast, the poorest 50% saw an 80% drop in their average net wealth over the same period. The data also reveal the growing role of inheritance and gifts inter vivos as a share of national income, as well as their increasing concentration at the top.

A growing literature conjectures that wealthy households earn higher average returns, which can further exacerbate wealth inequality. Using Swedish administrative data, this column shows that the wealthy indeed earn higher returns on their asset portfolios. These high returns are primarily due to high levels of compensated risk. Households at the top of the wealth distribution further exhibit highly heterogeneous investment performance due to high levels of idiosyncratic risk.
