Various definitions of economics have been proposed, including attempts to define precisely "what economists do". [1]
The term economics was originally known as "political economy". This term evolved from the French Mercantilist usage of économie politique, which expanded the notion of economy from the ancient Greek concept of household management to the national level, as the public administration of state affairs.
James Stuart (1767) authored the first book in English with 'political economy' in its title, explaining it just as:
The title page listed subjects including "population, agriculture, trade, industry, money, coins, interest, circulation, banks, exchange, public credit, and taxes".
In 1803, J.B. Say distinguished the subject from its public-policy uses, defining it as the science of the production, distribution, and consumption of wealth. [2] On the satirical side, Thomas Carlyle (1849) coined 'the dismal science' as an epithet for classical economics, a term often linked to the pessimistic analysis of Malthus (1798). [3] John Stuart Mill (1844) defined the subject in a social context as:
The shift from the social to the individual level appears within the main works of the Marginal Revolution. Carl Menger's definition reflects the focus on the economizing man:
William Stanley Jevons, another very influential author of the Marginal Revolution defines economics as highlighting the hedonic and quantitative aspects of the science:
Alfred Marshall provides a still widely cited definition in his textbook Principles of Economics (1890) that extends analysis beyond wealth and from the societal to the microeconomic level, creating a certain synthesis of the views of those still more sympathetic with the classical political economy (with social wealth focus) and those early adopters of the views expressed in the Marginal Revolution (with individual needs focus). His inclusion of the expression wellbeing was also very significant to the discussion on the nature of economics:
Lionel Robbins (1932) developed implications of what has been termed "perhaps the most commonly accepted current definition of the subject": [8]
Robbins describes the definition as not classificatory in "pick[ing] out certain kinds of behaviour" but rather analytical in "focus[ing] attention on a particular aspect of behaviour, the form imposed by the influence of scarcity". [10]
Some subsequent comments criticized the definition as overly broad in failing to limit its subject matter to analysis of markets. From the 1960s, however, such comments abated as the economic theory of maximizing behaviour and rational-choice modelling expanded the domain of the subject to areas previously treated in other fields. [11] There are other criticisms as well, such as in scarcity not accounting for the macroeconomics of high unemployment. [12]
Gary Becker, a contributor to the expansion of economics into new areas, describes the approach he favours as "combining the assumptions of maximizing behaviour, stable preferences, and market equilibrium, used relentlessly and unflinchingly". [13] One commentary characterizes the remark as making economics an approach rather than a subject matter but with great specificity as to the "choice process and the type of social interaction that such analysis involves". [14]
John Neville Keynes regarded the discussion leading up to the definition of economics more important than the definition itself. [15] It would be a way to reveal the scope, direction and troubles the science faces.
A recent review of economics definitions includes a range of those in principles textbooks, such as descriptions of the subject as the study of:
It concludes that the lack of agreement need not affect the subject-matter that the texts treat. Among economists more generally, it argues that a particular definition presented may reflect the direction toward which the author believes economics is evolving, or should evolve. [16]
The Austrian school is a heterodox school of economic thought that advocates strict adherence to methodological individualism, the concept that social phenomena result primarily from the motivations and actions of individuals along with their self interest. Austrian-school theorists hold that economic theory should be exclusively derived from basic principles of human action.
Economics is a social science that studies the production, distribution, and consumption of goods and services.
Thomas Robert Malthus was an English economist, cleric, and scholar influential in the fields of political economy and demography.
The term Homo economicus, or economic man, is the portrayal of humans as agents who are consistently rational and narrowly self-interested, and who pursue their subjectively defined ends optimally. It is a wordplay on Homo sapiens, used in some economic theories and in pedagogy.
Marginalism is a theory of economics that attempts to explain the discrepancy in the value of goods and services by reference to their secondary, or marginal, utility. It states that the reason why the price of diamonds is higher than that of water, for example, owes to the greater additional satisfaction of the diamonds over the water. Thus, while the water has greater total utility, the diamond has greater marginal utility.
The subjective theory of value (STV) is an economic theory for explaining how the value of goods and services are not only set but also how they can fluctuate over time. The contrasting system is typically known as the labor theory of value.
The dismal science is a derogatory term for the discipline of economics. Thomas Carlyle used the phrase in his 1849 essay "Occasional Discourse on the Negro Question" in contrast with the then-familiar phrase "gay science" used to refer to the art of troubadours.
Lionel Charles Robbins, Baron Robbins, was a British economist, and prominent member of the economics department at the London School of Economics (LSE). He is known for his leadership at LSE, his proposed definition of economics, and for his instrumental efforts in shifting Anglo-Saxon economics from its Marshallian direction. He is famous for the quote, "Humans want what they can't have."
John Ramsay McCulloch was a Scottish economist, author and editor, widely regarded as the leader of the Ricardian school of economists after the death of David Ricardo in 1823. He was appointed the first professor of political economy at University College London in 1828. He wrote extensively on economic policy, and was a pioneer in the collection, statistical analysis and publication of economic data.
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.
The 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. This definition enlarged the scope of economic science by emphasizing the study of wealth and humanity together, rather than wealth alone. In his widely read textbook, Principles of Economics, published in 1890, Marshall defines economics as follows:
Political Economy or Economics is a study of mankind in the ordinary business of life; it examines that part of individual and social action which is most closely connected with the attainment and with the use of material requisites of well-being.
The book An Essay on the Principle of Population was first published anonymously in 1798, but the author was soon identified as Thomas Robert Malthus. The book warned of future difficulties, on an interpretation of the population increasing in geometric progression while food production increased in an arithmetic progression, which would leave a difference resulting in the want of food and famine, unless birth rates decreased.
Regional economics is a sub-discipline of economics and is often regarded as one of the fields of the social sciences. It addresses the economic aspect of the regional problems that are spatially analyzable so that theoretical or policy implications can be the derived with respect to regions whose geographical scope ranges from local to global areas.
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.
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.
Lionel Robbins' Essay sought to define more precisely economics as a science and to derive substantive implications. Analysis is relative to "accepted solutions of particular problems" based on best modern practice as referenced, especially including the works of Philip Wicksteed, Ludwig von Mises, and other Continental European economists. Robbins disclaims originality but expresses hope to have given expository force on a very few points to some principles "not always clearly stated"
In the history of economic thought, a school of economic thought is a group of economic thinkers who share or shared a mutual perspective on the way economies function. While economists do not always fit within particular schools, particularly in the modern era, classifying economists into schools of thought is common. Economic thought may be roughly divided into three phases: premodern, early modern and modern. Systematic economic theory has been developed primarily since the beginning of what is termed the modern era.
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.
In economics, scarcity "refers to the basic fact of life that there exists only a finite amount of human and nonhuman resources which the best technical knowledge is capable of using to produce only limited maximum amounts of each economic good." If the conditions of scarcity did not exist and an "infinite amount of every good could be produced or human wants fully satisfied ... there would be no economic goods, i.e. goods that are relatively scarce..." Scarcity is the limited availability of a commodity, which may be in demand in the market or by the commons. Scarcity also includes an individual's lack of resources to buy commodities. The opposite of scarcity is abundance. Scarcity plays a key role in economic theory, and it is essential for a "proper definition of economics itself".
"The best example is perhaps Walras' definition of social wealth, i.e., economic goods. 'By social wealth', says Walras, 'I mean all things, material or immaterial, that are scarce, that is to say, on the one hand, useful to us and, on the other hand, only available to us in limited quantity'."
