Monetarism is a school of thought in monetary economics that emphasizes the role of policy-makers in controlling the amount of money in circulation. It gained prominence in the 1970s, but was mostly abandoned as a practical guidance to monetary policy during the following decade because the strategy was found to not work very well in practice.
Political economy is a branch of political science and economics studying economic systems and their governance by political systems. Widely studied phenomena within the discipline are systems such as labour markets and financial markets, as well as phenomena such as growth, distribution, inequality, and trade, and how these are shaped by institutions, laws, and government policy. Originating in the 16th century, it is the precursor to the modern discipline of economics. Political economy in its modern form is considered an interdisciplinary field, drawing on theory from both political science and modern economics.
Kenneth Joseph Arrow was an American economist, mathematician, writer, and political theorist. Along with John Hicks, he won the Nobel Memorial Prize in Economic Sciences in 1972.
In economics, industrial organization is a field that builds on the theory of the firm by examining the structure of firms and markets. Industrial organization adds real-world complications to the perfectly competitive model, complications such as transaction costs, limited information, and barriers to entry of new firms that may be associated with imperfect competition. It analyzes determinants of firm and market organization and behavior on a continuum between competition and monopoly, including from government actions.
Public choice, or public choice theory, is "the use of economic tools to deal with traditional problems of political science". Its content includes the study of political behavior. In political science, it is the subset of positive political theory that studies self-interested agents and their interactions, which can be represented in a number of ways – using standard constrained utility maximization, game theory, or decision theory. It is the origin and intellectual foundation of contemporary work in political economy.
Sir John Richard Hicks was a British economist. He is considered one of the most important and influential economists of the twentieth century. The most familiar of his many contributions in the field of economics were his statement of consumer demand theory in microeconomics, and the IS–LM model (1937), which summarised a Keynesian view of macroeconomics. His book Value and Capital (1939) significantly extended general-equilibrium and value theory. The compensated demand function is named the Hicksian demand function in memory of him.
Monetary economics is the branch of economics that studies the different theories of money: it provides a framework for analyzing money and considers its functions, and it considers how money can gain acceptance purely because of its convenience as a public good. The discipline has historically prefigured, and remains integrally linked to, macroeconomics. This branch also examines the effects of monetary systems, including regulation of money and associated financial institutions and international aspects.
Socioeconomics is the social science that studies how economic activity affects and is shaped by social processes. In general it analyzes how modern societies progress, stagnate, or regress because of their local or regional economy, or the global economy.
Information economics or the economics of information is the branch of microeconomics that studies how information and information systems affect an economy and economic decisions.
Philosophy and economics studies topics such as public economics, behavioural economics, rationality, justice, history of economic thought, rational choice, the appraisal of economic outcomes, institutions and processes, the status of highly idealized economic models, the ontology of economic phenomena and the possibilities of acquiring knowledge of them.
Social choice theory or social choice is a theoretical framework for analysis of combining individual opinions, preferences, interests, or welfares to reach a collective decision or social welfare in some sense. Whereas choice theory is concerned with individuals making choices based on their preferences, social choice theory is concerned with how to translate the preferences of individuals into the preferences of a group. A non-theoretical example of a collective decision is enacting a law or set of laws under a constitution. Another example is voting, where individual preferences over candidates are collected to elect a person that best represents the group's preferences.
Economic methodology is the study of methods, especially the scientific method, in relation to economics, including principles underlying economic reasoning. In contemporary English, 'methodology' may reference theoretical or systematic aspects of a method. Philosophy and economics also takes up methodology at the intersection of the two subjects.
Economic justice intersects with economic prosperity as if all members of society can earn wages then they are contributing to the economic growth. These wages are then turned into the buying of goods which works to drive the economy, but it only works if everyone can "provide for themselves and maintain discretionary income."
Public economics(or economics of the public sector) is the study of government policy through the lens of economic efficiency and equity. Public economics builds on the theory of welfare economics and is ultimately used as a tool to improve social welfare. Welfare can be defined in terms of well-being, prosperity, and overall state of being.
Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics. Often, these applied methods are beyond simple geometry, and may include differential and integral calculus, difference and differential equations, matrix algebra, mathematical programming, or other computational methods. Proponents of this approach claim that it allows the formulation of theoretical relationships with rigor, generality, and simplicity.
Demographic economics or population economics is the application of economic analysis to demography, the study of human populations, including size, growth, density, distribution, and vital statistics.
In economics, non-convexity refers to violations of the convexity assumptions of elementary economics. Basic economics textbooks concentrate on consumers with convex preferences and convex budget sets and on producers with convex production sets; for convex models, the predicted economic behavior is well understood. When convexity assumptions are violated, then many of the good properties of competitive markets need not hold: Thus, non-convexity is associated with market failures, where supply and demand differ or where market equilibria can be inefficient. Non-convex economies are studied with nonsmooth analysis, which is a generalization of convex analysis.
Convexity is an important topic in economics. In the Arrow–Debreu model of general economic equilibrium, agents have convex budget sets and convex preferences: At equilibrium prices, the budget hyperplane supports the best attainable indifference curve. The profit function is the convex conjugate of the cost function. Convex analysis is the standard tool for analyzing textbook economics. Non‑convex phenomena in economics have been studied with nonsmooth analysis, which generalizes convex analysis.
Peace economics is a branch of conflict economics and focuses on the design of the sociosphere's political, economic, and cultural institutions and their interacting policies and actions with the goal of preventing, mitigating, or resolving violent conflict within and between societies. This violent conflict could be of any type and could involve either latent or actual violence. Recognizing the cost of violence, peace economics focuses on the benefits of (re)constructing societies with a view toward achieving irreversible, stable peace. Along with approaches drawn from other areas of scholarship, peace economics forms part of peace science, an evolving part of peace and conflict studies.
Michael D. Intriligator was an American economist at the University of California, Los Angeles, where he was Professor of Economics, Political Science, and Policy Studies, and Co-Director of the Jacob Marschak Interdisciplinary Colloquium on Mathematics in the Behavioral Sciences. In addition, he was a Senior Fellow at the Milken Institute in Santa Monica, a Senior Fellow of the Gorbachev Foundation of North America in Boston, a Foreign Member of the Russian Academy of Science, and a Fellow of the American Association for the Advancement of Science. He received his Ph.D. in Economics at MIT in 1963 and the same year joined the UCLA Department of Economics. He taught courses in economic theory, econometrics, mathematical economics, international relations, and health economics, and received several distinguished teaching awards.
