The Lausanne School of economics, sometimes referred to as the Mathematical School, refers to the neoclassical economics school of thought surrounding Léon Walras and Vilfredo Pareto. It is named after the University of Lausanne, at which both Walras and Pareto held professorships. Polish economist Leon Winiarski is also said to have been a member of the Lausanne School.
The term Lausanne School was first coined by the mathematician Hermann Laurent in his article Petit traite d'economie politique mathematique (Small Treatise on Mathematical Political Economy).The central feature of the Lausanne School was its development of general equilibrium theory. Laurent's article presented a simplified version of this theory.
Lausanne School is also associated with the Italian School and the Paretian School, which were based on the works of Pareto.Italian economic historians have adopted Luigi Einaudi's description that the age of the Laussane School in Italy should be called "Italian school". The school is distinguished from the work of Alfred Marshall by the way it maintains the necessity of considering the interaction of all parts of the economy simultaneously so that the behavior that occurs within any part of it can be understood. Marshall, on the other hand, preferred to solve economic problems using mathematics as the instrument, with the theorist drawing out conclusions instead of coming up with solutions through the process of verbal reasoning.
The Laussane School attempted to answer the question of whether the welfare of an economy can be measured.Its theorists such as Walras proposed that it can be done through a notion of justice in exchange called "commutative justice", which required all traders to face the same price, which did not change, for a given product. This free competition is said to produce "maximum welfare", allowing for an effective evaluation of questions of welfare. Hans Mayer argued against Laussane School, citing that its assumptions are unrealistic and that the utility of a good cannot be measured, infinitely divided, nor indefinitely substituted.
Members of the Laussane School include Basile Samsonoff, Marie Kolabinska, and Pierre Boven, who were all students of Pareto.
Neoclassical economics is an approach to economics focusing on the determination of goods, outputs, and income distributions in markets through supply and demand. This determination is often mediated through a hypothesized maximization of utility by income-constrained individuals and of profits by firms facing production costs and employing available information and factors of production, in accordance with rational choice theory, a theory that has come under considerable question in recent years.
Vilfredo Federico Damaso Pareto was an Italian civil engineer, sociologist, economist, political scientist, and philosopher. He made several important contributions to economics, particularly in the study of income distribution and in the analysis of individuals' choices. He was also responsible for popularising the use of the term "elite" in social analysis.
Pareto efficiency or Pareto optimality is a situation where no individual or preference criterion can be better off without making at least one individual or preference criterion worse off or without any loss thereof. The concept is named after Vilfredo Pareto (1848–1923), Italian civil engineer and economist, who used the concept in his studies of economic efficiency and income distribution. The following three concepts are closely related:
In economics, general equilibrium theory attempts to explain the behavior of supply, demand, and prices in a whole economy with several or many interacting markets, by seeking to prove that the interaction of demand and supply will result in an overall general equilibrium. General equilibrium theory contrasts to the theory of partial equilibrium, which only analyzes single markets. In general equilibrium, constant influences are considered to be noneconomic, therefore, resulting beyond the natural scope of economic analysis.
Marie-Esprit-Léon Walras was a French mathematical economist and Georgist. He formulated the marginal theory of value and pioneered the development of general equilibrium theory. Walras is best known for his book "Éléments d'économie politique pure.", a work that has contributed greatly to the mathematization of economics through the concept of general equilibrium. The definition of the role of the entrepreneur found in it was also taken up and amplified by Schumpeter.
Welfare economics is a branch of economics that uses microeconomic techniques to evaluate well-being (welfare) at the aggregate (economy-wide) level.
Gérard Debreu was a French-born economist and mathematician. Best known as a professor of economics at the University of California, Berkeley, where he began work in 1962, he won the 1983 Nobel Memorial Prize in Economic Sciences.
Francis Ysidro Edgeworth was an Anglo-Irish philosopher and political economist who made significant contributions to the methods of statistics during the 1880s. From 1891 onward, he was appointed the founding editor of The Economic Journal.
Antoine Augustin Cournot was a French philosopher and mathematician who also contributed to the development of economics.
Michio Morishima was a Japanese heterodox economist and public intellectual who was the Sir John Hicks Professor of Economics at the London School of Economics from 1970–88. He was also professor at Osaka University and member of the British Academy. In 1976 he won the Order of Culture.
Geoffrey Martin Hodgson is a Professor in Management at the London campus of Loughborough University, and also the editor-in-chief of the Journal of Institutional Economics.
Applied economics is the application of economic theory and econometrics in specific settings. As one of the two sets of fields of economics, it is typically characterized by the application of the core, i.e. economic theory and econometrics to address practical issues in a range of fields including demographic economics, labour economics, business economics, industrial organization, agricultural economics, development economics, education economics, engineering economics, financial economics, health economics, monetary economics, public economics, and economic history. From the perspective of economic development, the purpose of applied economics is to enhance the quality of business practices and national policy making.
Enrico Barone was a soldier, military historian, and an economist.
The European Association for Evolutionary Political Economy (EAEPE) is a pluralist forum of social scientists that brings together institutional and evolutionary economists broadly defined. EAEPE members are scholars working on realistic approaches to economic theory and economic policy. With a membership of about 500, EAEPE is now the foremost European association for heterodox economists and the second-largest association for economists in Europe.
Zoltan J. Acs is an American economist. He is Professor of Management at The London School of Economics (LSE), and a professor at George Mason University, where he teaches in the Schar School of Policy and Government and is the Director of the Center for Entrepreneurship and Public Policy. He is also a visiting professor at Imperial College Business School in London and affiliated with the University of Pecs in Hungary. He is co-editor and founder of Small Business Economics, a leading academic journal.
Involuntary unemployment occurs when a person is willing to work at the prevailing wage yet is unemployed. Involuntary unemployment is distinguished from voluntary unemployment, where workers choose not to work because their reservation wage is higher than the prevailing wage. In an economy with involuntary unemployment there is a surplus of labor at the current real wage. This occurs when there is some force that prevents the real wage rate from decreasing to the real wage rate that would equilibrate supply and demand. Structural unemployment is also involuntary.
Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics. By convention, these applied methods are beyond simple geometry, such as differential and integral calculus, difference and differential equations, matrix algebra, mathematical programming, and other computational methods. Proponents of this approach claim that it allows the formulation of theoretical relationships with rigor, generality, and simplicity.
David Michael Garrood Newbery, CBE, FBA, is a Professor of Applied Economics at the University of Cambridge. He got this position in 1988. He specializes in the field of energy economics, and he writes on the regulation of electricity markets. His interests also include climate change mitigation and environmental policy, privatisation, and risk.
Thomas MacGillivray Humphrey is an American economist. Until 2005 he was a research advisor and senior economist in the research department of the Federal Reserve Bank of Richmond and editor of the Bank's flagship publication, the Economic Quarterly. His publications cover macroeconomics, monetary economics, and the history of economic thought. Mark Blaug called him the "undisputed master" of British classical monetary thought.
Ruth Towse FRSA is a British economist and Professor of Economics of Creative Industries at Bournemouth University and Professor Emerita at Erasmus University, Rotterdam.
