Educational Homogamy and Inter-Couple Income Inequality: Linking Demographic and Socio-Economic Consequences of Educational Expansion in Germany and Switzerland

How is educational expansion associated with increased educational homogamy and income inequality?

Educational homogamy thereby has had only a marginal impact on earnings-based income inequality between couples, which is largely due to the endogenous decision-making of couples concerning working time.
