If the “assortative matching hypothesis” (according to which people marry a spouse with broadly the same level of education) is verified, the impact on the distribution of household income per capita is un-equalizing if the first women who enter the labour market are well educated, and equalizing if they belong to low-income strata. The relationship between the average years of education of the LF and wage and income inequality is concave. In addition, if the supply of skilled workers grows less rapidly than its demand, scarcity rents and income inequality rise. As the relative abundance of skilled workers grows, scarcity rents and the wage rate of skilled workers stabilize and then decline, and the “wage premium” (sw/ uw) and earnings inequality drop.
