1.Rational choice theory
Rational choice theory, also known as choice theory or rational action theory, is a framework for understanding and often formally modeling social and economic behavior. Rationality, interpreted as "wanting more rather than less of a good", is widely used as an assumption of the behavior of individuals in microeconomic models and analysis and appears in almost all economics textbook treatments of human decision-making. It is also central to some of modern political science, sociology, and philosophy. It attaches "wanting more" to instrumental rationality, which involves seeking the most cost-effective means to achieve a specific goal without reflecting on the worthiness of that goal. Gary Becker was an early proponent of applying rational actor models more widely. He won the 1992 Nobel Memorial Prize in Economic Sciences for his studies of discrimination, crime, and human capital.
Classical liberalism is a political philosophy and ideology belonging to liberalism in which primary emphasis is placed on securing the freedom of the individual by limiting the power of the government. The philosophy emerged as a response to the Industrial Revolution and urbanization in the 19th century in Europe and the United States. It advocates civil liberties with a limited government under the rule of law, private property rights, and belief in laissez-faire economic liberalism. Classical liberalism is built on ideas that had already arisen by the end of the 18th century, including ideas of Adam Smith, John Locke, Jean-Baptiste Say, Thomas Malthus, and David Ricardo. Its greatest expression as a political (as well as economic) philosophy in the 19th century was in the works of John Stuart Mill. It drew on a psychological understanding of individual liberty, natural law, utilitarianism, and a belief in progress.
Decentralization (or decentralisation) is the process of redistributing or dispersing functions, powers, people or things away from a central location or authority. While centralization, especially in the governmental sphere, is widely studied and practiced, there is no common definition or understanding of decentralization. The meaning of decentralization may vary in part because of the different ways it is applied. Concepts of decentralization have been applied to group dynamics and management science in private businesses and organizations, political science, law and public administration, economics and technology.
