Political economy is the study of how economic systems and political systems are linked. 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.
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.
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.
Experimental economics is the application of experimental methods to study economic questions. Data collected in experiments are used to estimate effect size, test the validity of economic theories, and illuminate market mechanisms. Economic experiments usually use cash to motivate subjects, in order to mimic real-world incentives. Experiments are used to help understand how and why markets and other exchange systems function as they do. Experimental economics have also expanded to understand institutions and the law.
Computational Economics is an interdisciplinary research discipline that involves computer science, economics, and management science. This subject encompasses computational modeling of economic systems. Some of these areas are unique, while others established areas of economics by allowing robust data analytics and solutions of problems that would be arduous to research without computers and associated numerical methods.
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.
Eliot Roy Weintraub is an American mathematician, economist, and, since 1976, professor of economics at Duke University. He was born in 1943 in New York City.
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.
Economics imperialism is the economic analysis of non-economic aspects of life, such as crime, law, the family, prejudice, tastes, irrational behavior, politics, sociology, culture, religion, war, science, and research. Related usage of the term goes back as far as the 1930s.
Justice in economics is a subcategory of welfare economics. It is a "set of moral and ethical principles for building economic institutions". Economic justice aims to create opportunities for every person to have a dignified, productive and creative life that extends beyond simple economics.
Agent-based computational economics (ACE) is the area of computational economics that studies economic processes, including whole economies, as dynamic systems of interacting agents. As such, it falls in the paradigm of complex adaptive systems. In corresponding agent-based models, the "agents" are "computational objects modeled as interacting according to rules" over space and time, not real people. The rules are formulated to model behavior and social interactions based on incentives and information. Such rules could also be the result of optimization, realized through use of AI methods.
Leigh Tesfatsion is a computational economist who taught at Iowa State University. She received her doctorate at the University of Minnesota, and taught at the University of Southern California before moving to Iowa State. She is known for promoting agent-based models as an alternative to rational expectations general equilibrium models for studying markets, finance, and macroeconomic phenomena. Her works are widely cited in the literature on the subject.
John Duffy is an American economist. He is a professor of economics at the University of California, Irvine.
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.
Robert Wayne Clower was an American economist. He is credited with having largely created the field of stock-flow analysis in economics and with seminal works on the micro-foundations of monetary theory and macroeconomics.
The methodology of econometrics is the study of the range of differing approaches to undertaking econometric analysis.
Daniel M. Hausman is an American philosopher. His research has focussed primarily on methodological, metaphysical, and ethical issues at the boundaries between economics and philosophy. He is currently Herbert A. Simon Professor Emeritus in the Department of Philosophy at the University of Wisconsin–Madison.
Edward Emory Leamer is a professor of economics and statistics at UCLA. He is Chauncey J. Medberry Professor of Management and director of the UCLA Anderson Forecast.
