Governmental structure plays a pivotal role in determining policy outcomes as it establishes the distribution of power and responsibilities. Different structures, such as federal, unitary, or confederal systems, influence how policies are formulated and implemented. In federal systems, for example, power-sharing between national and state governments can lead to varied approaches to similar issues, while unitary systems centralize authority, resulting in more uniform policies. Additionally, the structure shapes the nature of political representation and public participation, ultimately affecting how policies respond to the needs and concerns of citizens.
