Résumé / Abstract Nous estimons un modèle de programmation dynamique des choix d'éducation dans lequel le degré d'aversion au risque peut être estimé à partir des choix de scolarisation. Dans notre modèle, les individus sont hétérogènes quant à leurs capacités scolaires et aptitudes sur le marché de l'emploi, mais homogènes en ce qui concerne le degré d'aversion au risque. Nous laissons les niveaux scolaires endogènes influencer le niveau de risque concernant les revenus d'emploi, et ce, à travers la dispersion des salaires et la dispersion du taux d'emploi. Nous trouvons un faible degré d'aversion relative au risque (0,9282) et nos résultats indiquent que les taux de dispersion, aussi bien pour le salaire que pour le taux d'emploi, diminuent de façon significative avec le niveau de scolarisation. Nous trouvons qu'une augmentation contrefactuelle de l'aversion au risque va faire augmenter le niveau de scolarité atteint. Finalement, un niveau faible d'aversion au risque implique qu'une augmentation de la dispersion des revenus aurait peu d'impact sur le niveau de scolarisation. We estimate a dynamic programming model of schooling decisions in which the degree of risk aversion can be inferred from schooling decisions. In our model, individuals are heterogeneous with respect to school and market abilities but homogeneous with respect to the degree of risk aversion. We allow endogenous schooling attainments to affect the level of risk experienced in labor market earnings through wage dispersion and employment rate dispersion. We find a low degree of relative risk aversion (0.9282) and the estimates indicate that both wage and employment rate dispersions decrease significantly with schooling attainments. We find that a counterfactual increase in risk aversion will increase schooling …

Absolute risk aversion and the returns to education
Absolute Risk Aversion and the Returns to Education Individual absolute risk aversion is measured for a sample of 1373 male household heads, using the 1995 wave of the Survey on the Income and Wealth of Italian households. This measure, conditional on financial and real wealth and household income, is used as an instrument for attained education in a standard log earnings equation. I find that,...
متن کاملOn Compensation for Risk Aversion and Skewness Affection in Wages
This paper presents extensive empirical testing of the hypothesis that greater post-schooling earnings risk requires higher expected returns. Expanding on this notion, on the basis of utility theory, we predict that workers not only care about risk but also about the skewness in the distribution of the compensation paid: workers exhibit risk aversion and skewness affection. To test these hypoth...
متن کاملIs There a Risk-return Trade-off in Educational Choices? Evidence from Spain
We use data from Spain to test for an e ect of earnings variance and skewness on individual wages. We carry out separate estimations for men and women. In accordance with the scant previous evidence mainly focused on the US, we report the existence of a risk-return trade-o across educational choices in the Spanish labor market. These results are in conformity with preferences of risk-averse ind...
