This article explores the determinants of actual job sector decisions of highly skilled professionals across four different sectors in a developing country, with a particular interest in the relationship with public service motivation (PSM). Unlike most previous cross-sectional studies, it uses a pooled time series of individual antecedents and job characteristics, both before and after the individuals leave the job market to pursue graduate education abroad. The results indicate that there are key differences in terms of the determinants of job sector choices across the four sectors, and that PSM appears to have a differential role on the attraction of individuals to each of those sectors.
