Social Mobility and Political Instability

Does social mobility foster political stability? While there is a vibrant literature on the effect of economic inequality on political unrest, the recent literature has remained silent about the effect of social mobility on instability. Yet, inequality and social mobility, although related, are fundamentally distinct, and immobility is likely to be perceived as even more unfair than inequality, meaning that it may generate at least as much grievances. In this article, I argue that social immobility fuels political instability. To test this hypothesis, I develop an indicator of social mobility covering more than 100 countries worldwide. I then conduct the first large- N cross-national test of the effect of social mobility on political instability to date. Consistent with my argument, I find that countries with low social mobility levels are more likely to experience riots, general strikes, antigovernment demonstrations, political assassinations, guerillas, revolutions, and civil wars.
