Non-linearities in returns to education in Libya [Ressource électronique]

This paper presents evidence that returns to schooling in Libya are nonlinear. However, this evidence should not be taken as supporting the sheepskin effect. Although high-school graduation is associated with higher earnings over and above what is predicted by the linear model, other diploma years do not possess the same advantage when a spline function is used.When a step function is used, various years, some of which do not lead to a diploma, show high marginal returns.
