概要	Fiscal decentralization analysis examines how taxing, spending and borrowing powers are divided among levels of government — central, regional and local — and what that division means for efficiency, equity and accountability. Its theoretical foundation is the fiscal federalism tradition pioneered by Wallace Oates, whose 1972 book Fiscal Federalism and 1999 essay set out when decentralized provision improves welfare and how intergovernmental transfers should be designed. The method maps the assignment of revenues and expenditures across tiers, measures the degree of decentralization and the gap between subnational spending and own revenue, and assesses how these arrangements affect service delivery, redistribution and the accountability of governments to citizens.	Policy feedback analysis examines how policies, once enacted, reshape the politics that follow — turning yesterday's policy effects into today's political causes. Drawing on Paul Pierson's foundational 1993 article 'When Effect Becomes Cause,' it holds that policies are not just outputs of politics but powerful forces that create resources and incentives for groups, build administrative capacities, and shape how citizens understand their interests and their government. By tracing these resource and interpretive feedback effects over time, the method explains why some policies become self-reinforcing and politically durable, why others undermine their own support, and why policy change is often path-dependent and hard to reverse.
