The recovery after the COVID-19 crisis requires policies and reforms that tackle inequalities and promote equal opportunities. However, the implementation of such reforms requires widespread support from the public. To better understand what factors drive public support, this report provides a detailed cross-country analysis of people’s perceptions of and concern over inequality.

Abstract: We explore the effect of income mobility and the persistence of redistributive tax policy on the level of redistribution in democratic societies. An infinite-horizon theoretical model is developed, and the properties of the equilibrium tax rate and the degree of after-tax inequality are characterized. Mobility and stickiness of tax policy are both negatively related to the equilibrium tax rate. However, neither is sufficient by itself. Social mobility has no effect on equilibrium taxes if tax policy is voted on in every period, and tax persistence has no effect in the absence of social mobility. The two forces are complementary. Tax persistence leads to higher levels of post-tax inequality, for any amount of mobility. The effect of mobility on inequality is less clear-cut and depends on the degree of tax persistence. A laboratory experiment is conducted to test the main comparative static predictions of the theory, and the results are generally supportive

Eight papers, both theoretical and applied, on the concept of equality of opportunity which says that a society should guarantee its members equal access to advantage regardless of their circumstances, while holding them responsible for turning that access into actual advantage by the application of effort.

We posit that the relationship between income inequality and economic growth is mediated by the level of equality of opportunity, which we identify with intergenerational mobility. In economies characterized by intergenerational rigidities, an increase in income inequality has persistent effects—for example by hindering human capital accumulation— thereby retarding future growth disproportionately. We use several recently developed internationally comparable measures of intergenerational mobility to confirm that the negative impact of income inequality on growth is higher the lower is intergenerational mobility. Our results suggest that omitting intergenerational mobility leads to misspecification, shedding light on why the empirical literature on income inequality and growth has been so inconclusive.

Mareike Schad examines how redistributive policy measures influence intergenerational income mobility, taking into account various facets of the parent-child connection. In the first part, the author investigates the impact of education and education policy on income mobility both theoretically and empirically. The second part addresses individual beliefs regarding the determinants of personal economic success and their effect on income mobility within a society.
