Policies, parties, and protests: explaining student protest events in Latin America

What explains variation in the emergence of college student protests in Latin America? This study uses an original dataset of 4,700 college student protests to carry out a systematic analysis of student mobilization in the region. This article tests three hypotheses based on two distinct but complementary explanations. The political explanation argues that stronger organizational linkages with ruling parties have a demobilizing effect, while the explanation based on grievances claims that increases in enrollments and private expenditures promote mobilization. Regression analyses are used to tests these claims. Increased private spending does not affect mobilization, while expanded access to college does increase the frequency of protests. To gauge the effect of party linkages, two student-party linkages scores, based on an expert survey, are used. The findings show that stronger linkages with ruling parties lower protest frequency whereas linkages with the opposition do not have a significant effect.
