Post-autistic economicsThe post-autistic economics movement (autisme-économie), or movement of students for the reform of economics teaching (mouvement des étudiants pour une réforme de l'enseignement de l'économie), is a political movement that criticises neoclassical economics and advocates for pluralism in economics. The movement gained attention after an open letter signed by almost a thousand economics students at French universities and grandes ecoles was published in Le Monde in 2000.
Structuralist economicsStructuralist economics is an approach to economics that emphasizes the importance of taking into account structural features (typically) when undertaking economic analysis. The approach originated with the work of the Economic Commission for Latin America (ECLA or CEPAL) and is primarily associated with its director Raúl Prebisch and Brazilian economist Celso Furtado. Prebisch began with arguments that economic inequality and distorted development was an inherent structural feature of the global system exchange.
Marginal rate of substitutionIn economics, the marginal rate of substitution (MRS) is the rate at which a consumer can give up some amount of one good in exchange for another good while maintaining the same level of utility. At equilibrium consumption levels (assuming no externalities), marginal rates of substitution are identical. The marginal rate of substitution is one of the three factors from marginal productivity, the others being marginal rates of transformation and marginal productivity of a factor.
Foundations of Economic AnalysisFoundations of Economic Analysis is a book by Paul A. Samuelson published in 1947 (Enlarged ed., 1983) by Harvard University Press. It is based on Samuelson's 1941 doctoral dissertation at Harvard University. The book sought to demonstrate a common mathematical structure underlying multiple branches of economics from two basic principles: maximizing behavior of agents (such as of utility by consumers and profits by firms) and stability of equilibrium as to economic systems (such as markets or economies).
Marginal revenueMarginal revenue (or marginal benefit) is a central concept in microeconomics that describes the additional total revenue generated by increasing product sales by 1 unit. Marginal revenue is the increase in revenue from the sale of one additional unit of product, i.e., the revenue from the sale of the last unit of product. It can be positive or negative. Marginal revenue is an important concept in vendor analysis.
Social costSocial cost in neoclassical economics is the sum of the private costs resulting from a transaction and the costs imposed on the consumers as a consequence of being exposed to the transaction for which they are not compensated or charged. In other words, it is the sum of private and external costs. This might be applied to any number of economic problems: for example, social cost of carbon has been explored to better understand the costs of carbon emissions for proposed economic solutions such as a carbon tax.
Rational agentA rational agent or rational being is a person or entity that always aims to perform optimal actions based on given premises and information. A rational agent can be anything that makes decisions, typically a person, firm, machine, or software. The concept of rational agents can be found in various disciplines such as artificial intelligence, cognitive science, decision theory, economics, ethics, game theory, and the study of practical reason. In reference to economics, rational agent refers to hypothetical consumers and how they make decisions in a free market.
Welfare definition of economicsThe welfare definition of economics is an attempt by Alfred Marshall , a pioneer of neoclassical economics, to redefine his field of study. This definition expands the field of economic science to a larger study of humanity. Specifically, Marshall's view is that economics studies all the actions that people take in order to achieve economic welfare. In the words of Marshall, "man earns money to get material welfare." Others since Marshall have described his remark as the "welfare definition" of economics.
Price signalA price signal is information conveyed to consumers and producers, via the prices offered or requested for, and the amount requested or offered of a product or service, which provides a signal to increase or decrease quantity supplied or quantity demanded. It also provides potential business opportunities. When a certain kind of product is in shortage supply and the price rises, people will pay more attention to and produce this kind of product.
Endowment effectIn psychology and behavioral economics, the endowment effect (also known as divestiture aversion and related to the mere ownership effect in social psychology) is the finding that people are more likely to retain an object they own than acquire that same object when they do not own it. The endowment theory can be defined as "an application of prospect theory positing that loss aversion associated with ownership explains observed exchange asymmetries." This is typically illustrated in two ways.
