Summary This paper investigates the impact of regional political instability on the political instability of a country. Our identification strategy relies on the spatial nature of international relations. We use the characteristics of the neighbors’ neighbors as the instruments for the neighbors’ political instability and regional dummies to control for common regional shocks. We show that political instability in neighboring countries has a strong positive impact on a given country's political instability. The average of neighbors’ population size appears to be a significant mediating factor behind this relationship.
