This paper looks at how much power should be given to different levels of government to make sure they work in the best interests of the people. Centralizing power can help coordinate policies, but it can also reduce accountability. Accountability means that people in a region can influence whether the government gets re-elected. The paper also considers conflicts of interest within regions, and how central and local governments affect each other in a federation. It also talks about how money should be shared between different areas, and when governments might use resources for their own benefit.
