Domain: Taxation and Fiscal Policy
How tax structure, revenue mobilization, and fiscal policy affect economic growth, inequality, and public goods provision
Temporal scope: 1990-present | Population: Countries worldwide
Key Findings
- Tax revenue mobilization is positively associated with public goods quality and state capacity, with countries collecting more tax revenue providing better infrastructure, education, and health services (positive, strong)
- Progressive taxation reduces income inequality with moderate efficiency costs, though the optimal top marginal rate depends on behavioral elasticities that vary across contexts (conditional, moderate)
- Tax cuts have asymmetric effects across the income distribution, with cuts for lower-income households generating higher fiscal multipliers than cuts for higher-income households (conditional, moderate)
