Read my comments presented to the Public Economics Forum on “Intergenerationally Disadvantaged: Newest Evidence and What it Means for Policy,” organized by the Melbourne Institute for Applied Economic and Social Research, on November 26th, 2019 in Canberra, Australia.
Social mobility varies across countries, but it varies in a particular way, a way that I argue is relevant for the conduct of public policy.
Inequality begets inequality. Up to 50% of income inequality is passed on to the next generation in countries like the United Kingdom, Italy, and the United States, but only 20% or even less in countries like Norway, Denmark and Finland, where there is a much smaller gap between parent incomes.
But different kinds of inequality matter in different ways for social mobility.
Research using the variation of social mobility within countries like the United States and Canada shows that intergenerational cycles of low income are more likely in communities that have more bottom half inequality, the correlation with overall inequality and with top end inequality being much weaker. Upward mobility is easier when the poorest incomes are not that far off from middle incomes.
The bottom line for public policy is don’t let inequality increase in the bottom half of the income distribution, indeed strive to reduce it in a way that encourages labour market and social engagement.
