Yes, political dynasty is a factor in worsening the crises and conflicts of a country. Political dynasties are
common in most countries around the world, but we know little about how dynastic rule affects
economic development. Close family members are the worst-performing dynasties, suggesting that
easier access to party tickets may explain underperformance. Dynasties appear to have weaker
performance incentives than non-dynasties, as their vote shares in subsequent elections are less
correlated with in-office performance today. In this way, inheriting political capital may mute the
performance incentives of dynastic politicians. But there are several evidence that politicians with sons
perform better in office, suggesting that incentives to establish a dynasty can motivate better
performance. In countries across the world where broad political institutions are weak and local familial
and kin networks are strong, politics is necessarily shaped by the logic and loyalties of kinship. And when
dynasties grow powerful enough to dominate political contestation, this in turn means that the
vendettas to which kinship networks are prone can grow strong enough to drag weaker states and their
populations into warfare and widespread conflict.
