Why is southern Italy poorer than northern Italy?

3 hours ago

Northern Italy's historical traditions of self-government and civic participation fostered higher social capital, lower corruption, and greater trust.
Southern Italy was shaped by hierarchical authority, landlord domination, and weaker collective action, leading to lower trust and more patronage.
Malaria historically influenced Southern Italy's development by promoting large estates and absentee landlordism, which hindered education and industrialization.
Medieval self-government in Northern Italy left durable effects on modern social capital, accounting for at least half of the North-South gap.
The rise of the Sicilian Mafia in the late 19th century, linked to peasant mobilization and weak state capacity, reduced literacy and public goods.
Recent studies show that breaking Mafia infiltration in local governments can increase employment and economic activity in affected sectors.
Land concentration, driven by malaria exposure, adversely affected literacy and educational outcomes in Southern Italy from 1871 to 1921.
Social capital is a proximate cause of the divergence, while malaria, medieval institutions, and organized crime are among the ultimate causes.
The literature provides a coherent understanding of Italy's North-South developmental gap, combining proximate and ultimate factors.
