Subnational governments' capacity to effectively fund and deliver public services are crucial for the realisation of the benefits of decentralisation. However, subnational capacities often suffer from significant weaknesses, ranging from inadequate assignments of own-revenues, through to flaws in tax administration, the design of intergovernmental transfers, spending assignments and various aspects of public financial management. The volume discusses how better diagnostics and more strategic reforms can contribute to easing the resource constraints on subnational governments, as well as creating appropriate incentives for these governments to improve performance. The volume includes studies of the enabling conditions for subnational capacity building in Asia, as well as focused studies of China and India's fiscal relations challenges.
