Public Policy Theory examines how policies are created, implemented, and evaluated within a society. It focuses on understanding the processes that influence decision-making and the factors that shape public policies, including political, economic, and social contexts. The theory helps identify the roles of various stakeholders, such as government agencies, interest groups, and citizens, in shaping policy outcomes. Additionally, Public Policy Theory explores different models and frameworks, such as the rational model and incrementalism, to analyze how policies evolve over time. By studying these theories, policymakers can better understand the complexities of governance and improve the effectiveness of public policies in addressing societal issues.
