This article aims to study and estimate the evolution of the profitability of educational and professional investments, thus offering an analysis of the dynamic links “profitability” - “investment”. The general framework is inspired by the theory of human capital and by analyzing three surveys provided by the National Institute of Statistics which focus on salaried 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. The results provide insight into the dynamics of individual investment choices. Where estimates show declining profitability and increasing catch-up time (Overtaking) The study also helps to understand the evolution of returns on educational and professional investments. As well as identifying points of failure and imbalance in the education system and its relation to the labor market and serving as a guide for government policy regarding long-term educational programs.
