When explaining the determinants of salary (or employment) of individuals, tradicional Mincer's models include "age", "number of years of formal education" and "experience in labor market" as the most relevant explanatory variables of income or success in the labour market.
But this leaves aside the health variables as part of human capital concept. In addition, they leave aside some mental health variables (or characters) without which the academic or "labor market" outcomes could never be achieved.
So, is mental health feasable to incorporate as an additional explanatory variable in an econometric model of salary (or employment level)?
