These paper aims are to study and estimate the evolution of the inequalities to the return on educational and professional investment, thus offering vast opportunities for analysis, in particular the dynamic links "profitability" - "investment".
The general view is titled in the research field of human capital theory by analyzing three surveys provided by the National Statistical Institute that focus on wage-employment.
We initially use a corrected Mincer model where we specify two types of regression then we will integrate the indicator of depreciation of human capital. Thus giving results that are used to understand the dynamics of individual investment choices. The results show a decrease in profitability and an increase in catch-up time (Overtaking).
The study also makes it possible to understand the evolution of returns on educational and professional investments. To look for points of failure and imbalances in the education system and its relation to the labor market and to serve as a guide to government policy as it relates to long-term educational programs.
