What is behind University Dropout Decision in Brazil? A Bivariate Probability Model

In this paper we analyze the major determinants of university enrollment and dropout in Brazil. The econometric model consists of two simultaneous equations. The first equation determines whether the student was accepted at the university or not; the second determines students decision to dropout or not from higher education, given they were accepted at the university. Gender, age and marriage influence not only acceptance but also the decision to dropout. As usual family background is also an important determinant of both, and in that matter, family income plays a major role on student's performance and their decision to dropout.
