We investigate the nature of protests by students (age 18 and older) in Algeria, Jordan, Morocco, and Yemen by using subsamples of students from nationally representative and acclaimed public opinion data (the 2006-07 "Arab Barometer"). We find between 22.1% (Jordan) and 54.7% (Yemen) participated in either the signing of petitions, or marching in street protests, or both between the years 2003-07. To explain student protest participation, we draw from the political economy literature to test four grievance-based hypotheses that link protest to student perceptions on the performance of the economy, personal family socioeconomic status, political exclusion, and preference for democracy. Ordered probit regression analyses indicate that students protest for different reasons in the four countries. We find statistical evidence that student protests are associated with grievances about the economy (Algeria and Morocco) and lack of democracy (Algeria only). Joint hypothesis tests reveal that the four grievances jointly matter in Algeria, Morocco, and Yemen but not Jordan.
