The three dimensions of power that shape the influence of political executives are the formal, informal, and external dimensions

In a presidential system, the president is both head of state and head of government, usually directly elected by the people
Functions of the legislature
Legislation

Federalism

Features of a federal government
Two relatively autonomous levels of government
Written constitution
Constitutional arbiter (the judiciary)
Representatives like the legislature
Federal systems are favored because they give regional and local interests a constitutionally guaranteed political voice, diffuse government power to create checks and balances, and provide an institutional mechanism for fractured societies to maintain unity and coherence
The vast majority of contemporary states have unitary systems of government
Countries with unitary government
United Kingdom
France
Japan
Philippines
In unitary states, there are two distinct institutional forms of peripheral authority: local governments and local legislatures
Local government
Governing body in a specific locality
Devolution
Decentralized unitary form of government transitioning to federalism
Local governments have democratic legitimacy that enables them to extend their formal powers and responsibilities, through a process of bargaining and negotiation with central authority
Devolution in the Philippines establishes the greatest possible measure of decentralization in a unitary system of government, short of transforming it into a federal system
