Nontechnical SummaryImproving the education of youth is one of the most prominent policy goals in Europe. While most economists would agree with the aim, the optimal timing and the optimal quantity of educational investments are in question.This paper analyses alternative investment policies and their consequences for the evolution of human capital in Europe based on a model of age dependent skill formation where the life span depends on investments during childhood. A model is calibrated for a population living in 29 European countries in the year 2006. In the study Europe is either the sum of these individual countries or it is a hypothetical entity constructed from the 29 European countries.What makes the approach special is the analysis of the returns to education of alternative educational policies targeted at certain countries, ages or productivity levels for two counterfactual policy regimes, one regime assuming a single labour market and the other presupposing the actual state of diversity. In the model, investments for young individuals under the age of eighteen years are traced back to the family and teaching environment. In adulthood individuals optimize the amount of educational investments, given the overall amount of investments in the society. We analyse the consequences of each investment policy for human capital formation over the whole life cycle and do not focus on specific developmental stages like preschool or tertiary education.The results demonstrate that optimal investment strategies, whether they are oriented towards age, regions or skill levels, crucially depend on the weights a society puts on equality. If equality is important enough more investment in Europe are needed for disadvantaged children during childhood. If the aim of equality is less important, additional investments need to be directed more generally to people of younger ages. Furthermore, it turns out that high levels of income inequality and a high skill level increases the optimal amount of investments, especially during younger adulthood.In the case where educational costs and skill premia are modelled as homogeneous in Europa the effectiveness of policies to reduce inequality would be higher.The findings result from the idea of age depended skill formation with decreasing learning multiplier over time and decreasing marginal returns to investment in ...
