Public choice theory is a branch of economics that studies the behavior of individuals and groups in the political decision-making process. It examines how politicians and bureaucrats interact with citizens and interest groups to make public policy decisions. Synonyms for public choice theory include collective choice theory, political economy, and social choice theory. These terms all refer to the study of decision-making in political systems and the impact it has on society as a whole. Whether examining economic policies, social programs, or environmental regulations, understanding public choice theory is crucial for policymakers, academics, and citizens alike. As our world becomes increasingly complex, the need to understand the dynamics of public choice theory only grows more important.
