This work looks at the various principles of revenue allocation, on how to share revenue among the tiers of government and how to allocate revenue among the components of a particular tier. It equally examines the concept, pillars, and reasons for fiscal decentralization. The research also looks at the advantages and disadvantages of decentralization, making an overview of revenue allocation in Cameroon and putting forward recommendations.
