Political scientists from the Southern Cone have enriched the discipline with pioneering work. Many of them went into exile for political reasons, and thus produced part of their work abroad. Although Latin American political science has professionalized since the 1980s, many scholars still emigrate for study and employment. Argentines most numerously seek academic careers abroad, while Brazil has many more domestic doctorates and returns home after doctoral studies abroad. Uruguayans emigrate in proportionally high numbers and tend to settle in Latin American countries, while the number of Chileans and Paraguayans abroad is minimal. These contrasting patterns are explained by reference to factors such as the availability of high-quality doctoral courses, financing for postgraduate studies, and the absorptive capacity of national academic markets. Paradoxically, the size and performance of the diasporas may increase rather than reduce the visibility and impact of national political science communities.
