This paper provides evidence of the intergenerational mobility of economic wellbeing for the countries of the EU-15. We deal with the potential endogeneity of the transmission parameter by exploiting the presence of heteroskedasticity in a cross-sectional setting, using rank-order IV and conditional second moments estimation. OLS and panel (Fixed Effects and First Differences) models are also estimated, providing the upper and lower bounds for the true causal effect, not only for fathers and sons, but also for fathers and daughters, mothers and sons and mothers and daughters, in each of the sample countries. Our findings suggest that income well-being is much more persistent across generations in Southern European countries than in Finland, Denmark, the Netherlands and the UK.
