Marginalism
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. Although the central concept of marginalism is that of marginal utility, marginalists, following the lead of Alfred Marshall, drew upon the idea of Marginal product, marginal physical productivity in explanation of cost. The Neoclassical economics, neoclassical tradition that emerged from United Kingdom of Great Britain and Ireland, British marginalism abandoned the concept of utility and gave Marginal rate of substitution, marginal rates of substitution a more fundamental role in analysis. Marginalism is an integral part of mainstream economics, mainstream ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marginal Utility
Marginal utility, in mainstream economics, describes the change in ''utility'' (pleasure or satisfaction resulting from the consumption) of one unit of a good or service. Marginal utility can be positive, negative, or zero. Negative marginal utility implies that every consumed additional unit of a commodity causes more harm than good, leading to a decrease in overall utility. In contrast, positive marginal utility indicates that every additional unit consumed increases overall utility. In the context of cardinal utility, liberal economists postulate a law of diminishing marginal utility. This law states that the first unit of consumption of a good or service yields more satisfaction or utility than the subsequent units, and there is a continuing reduction in satisfaction or utility for greater amounts. As consumption increases, the additional satisfaction or utility gained from each additional unit consumed falls, a concept known as ''diminishing marginal utility.'' This idea is us ...

Neoclassical Economics
Neoclassical economics is an approach to economics in which the production, consumption, and valuation (pricing) of goods and services are observed as driven by the supply and demand model. According to this line of thought, the value of a good or service is determined through a hypothetical maximization of utility by income-constrained individuals and of profits by firms facing production costs and employing available information and factors of production. This approach has often been justified by appealing to rational choice theory. Neoclassical economics is the dominant approach to microeconomics and, together with Keynesian economics, formed the neoclassical synthesis which dominated mainstream economics as "neo-Keynesian economics" from the 1950s onward. Classification The term was originally introduced by Thorstein Veblen in his 1900 article "Preconceptions of Economic Science", in which he related marginalists in the tradition of Alfred Marshall ''et al.'' to ...

Alfred Marshall
Alfred Marshall (26 July 1842 – 13 July 1924) was an English economist and one of the most influential economists of his time. His book ''Principles of Economics (Marshall), Principles of Economics'' (1890) was the dominant economic textbook in England for many years, and brought the ideas of supply and demand, marginal utility, and costs of production into a coherent whole, popularizing the modern Neoclassical economics, neoclassical approach which dominates microeconomics to this day. As a result, he is known as the father of scientific economics. Life and career Marshall was born at Bermondsey in London, the second son of William Marshall (1812–1901), a clerk and cashier at the Bank of England, and Rebecca (1817–1878), daughter of butcher Thomas Oliver, from whom, on her mother's death, she inherited property. Marshall had two brothers and two sisters; a cousin was the economist Ralph George Hawtrey, Ralph Hawtrey. The Marshalls were a West Country clergy, clerical f ...

Marginal Use
As defined by the Austrian School of economics the marginal use of a good or service is the specific use to which an agent would put a given increase, or the specific use of the good or service that would be abandoned in response to a given decrease.von Wieser, Friedrich; ''Über den Ursprung und die Hauptgesetze des wirtschaftlichen Wertes'' ''The Nature and Essence of Theoretical Economics''">/nowiki>''The Nature and Essence of Theoretical Economics''/nowiki> (1884), p. 128. The useful''ness'' of the marginal use thus corresponds to the marginal utility of the good or service.Mc Culloch, James Huston“The Austrian Theory of the Marginal Use and of Ordinal Marginal Utility” ''Zeitschrift für Nationalökonomie'' 37 (1977) #3&4 (September). On the assumption that an agent is economically rational, each increase would be put to the specific, feasible, previously unrealized use of greatest priority, and each decrease would result in abandonment of the use of lowest priority ...

Hermann Heinrich Gossen
Hermann Heinrich Gossen (7 September 1810 – 13 February 1858) was a German economist who is often regarded as the first to elaborate, in detail, a general theory of marginal utility. Prior to Gossen, a number of economic theorists, including Gabriel Cramer, Daniel Bernoulli, William Forster Lloyd, Nassau William Senior, and Jules Dupuit had employed or asserted the significance of some notion of marginal utility. But Cramer, Bernoulli, and Dupuit had focussed upon specific problems, Lloyd had not presented any applications of theory, and if Senior provided a detailed elaboration of the general theory he had developed, he had done so in language that caused his applications of theory to be missed by most readers. Life and family background Hermann Heinrich Gossen was born in Düren, Roer (department) (Roerdépartement, or Département de la Roer), First French Empire. Today that area is known as North Rhine-Westphalia, Germany. Hermann died in Cologne (Köln), North Rhine-W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journal Of Political Economy
The ''Journal of Political Economy'' is a monthly peer-reviewed academic journal published by the University of Chicago Press. Established by James Laurence Laughlin in 1892, it covers both theoretical and empirical economics. In the past, the journal published quarterly from its introduction through 1905, ten issues per volume from 1906 through 1921, and bimonthly from 1922 through 2019. The editor-in-chief is Esteban Rossi-Hansberg (University of Chicago). It is considered one of the top five journals in economics. JPE Micro and JPE Macro In 2023, University of Chicago Press announced the establishment of Journal of Political Economy Microeconomics (JPE Micro) and Journal of Political Economy Macroeconomics (JPE Macro), two new journals that are vertically integrated with the Journal of Political Economy.

Measure (mathematics)
In mathematics, the concept of a measure is a generalization and formalization of geometrical measures (length, area, volume) and other common notions, such as magnitude, mass, and probability of events. These seemingly distinct concepts have many similarities and can often be treated together in a single mathematical context. Measures are foundational in probability theory, integration theory, and can be generalized to assume negative values, as with electrical charge. Far-reaching generalizations (such as spectral measures and projection-valued measures) of measure are widely used in quantum physics and physics in general. The intuition behind this concept dates back to Ancient Greece, when Archimedes tried to calculate the area of a circle. But it was not until the late 19th and early 20th centuries that measure theory became a branch of mathematics. The foundations of modern measure theory were laid in the works of Émile Borel, Henri Lebesgue, Nikolai Luzin, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeitschrift Für Nationalökonomie
''Journal of Economics'', founded as ''Zeitschrift für Nationalökonomie'', is an academic journal of economics with an emphasis on Mathematical economics, mathematical Microeconomics, microeconomic theory, although it publishes occasional articles on macroeconomics. ''Zeitschrift für Nationalökonomie'' was first published in 1930, as a revival of an earlier ''Zeitschrift für Volkswirtschaft, Sozialpolitik und Verwaltung'' which was published from 1892 into 1927 (from 1921 under the name ''Zeitschrift für Volkswirtschaft und Socialpolitik''). The initial editor of ''Zeitschrift für Nationalökonomie'' was Hans Mayer, a third-generation member of the Austrian School. Mayer avowedly welcomed contributions from all schools of thought, so long as the work were scientifically rigorous and not List of political ideologies, politically ideological in nature.Hans Mayer: ''Zur Einführung''.

George Stigler
George Joseph Stigler (; January 17, 1911 – December 1, 1991) was an American economist. He was the 1982 laureate in Nobel Memorial Prize in Economic Sciences and is considered a key leader of the Chicago school of economics. Early life and education Stigler was born in Seattle, Washington, the son of Hungarian Elsie Elizabeth (Erzsébet Hungler, born in Bakonypéterd, Veszprém county, Kingdom of Hungary) and Bavarian Joseph Stigler. He was of German and Hungarian descent and spoke German in his childhood. He graduated from the University of Washington in 1931 with a B.A. and then spent a year at Northwestern University, from which he obtained his MBA in 1932. It was during his studies at Northwestern that Stigler developed an interest in economics and decided on an academic career. After he received a tuition scholarship from the University of Chicago, Stigler enrolled there in 1933 to study economics and went on to earn his PhD in economics in 1938. Career Stigler t ...

Economics
Economics () is a behavioral science that studies the Production (economics), production, distribution (economics), distribution, and Consumption (economics), consumption of goods and services. Economics focuses on the behaviour and interactions of Agent (economics), economic agents and how economy, economies work. Microeconomics analyses what is viewed as basic elements within economy, economies, including individual agents and market (economics), markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyses economies as systems where production, distribution, consumption, savings, and Expenditure, investment expenditure interact; and the factors of production affecting them, such as: Labour (human activity), labour, Capital (economics), capital, Land (economics), land, and Entrepreneurship, enterprise, inflation, economic growth, and public policies that impact gloss ...

Special Case
In logic, especially as applied in mathematics, concept is a special case or specialization of concept precisely if every instance of is also an instance of but not vice versa, or equivalently, if is a generalization of .Brown, James Robert. Philosophy of Mathematics: An Introduction to a World of Proofs and Pictures'. United Kingdom, Taylor & Francis, 2005. 27. A limiting case is a type of special case which is arrived at by taking some aspect of the concept to the extreme of what is permitted in the general case. If is true, one can immediately deduce that is true as well, and if is false, can also be immediately deduced to be false. A degenerate case is a special case which is in some way qualitatively different from almost all of the cases allowed. Examples Special case examples include the following: * All squares are rectangles (but not all rectangles are squares); therefore the square is a special case of the rectangle. It is also a special case of the rhombus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceteris Paribus
' (also spelled ') (Classical ) is a Latin phrase, meaning "other things equal"; some other English translations of the phrase are "all other things being equal", "other things held constant", "all else unchanged", and "all else being equal". A statement about a causal, empirical, moral, or logical relation between two states of affairs is ''ceteris paribus'' if it is acknowledged that the statement, although usually accurate in expected conditions, can fail because of, or the relation can be abolished by, intervening factors. chapter 2 A ''ceteris paribus'' assumption is often key to scientific inquiry, because scientists seek to eliminate factors that perturb a relation of interest. Thus epidemiologists, for example, may seek to control independent variables as factors that may influence dependent variables—the outcomes of interest. Likewise, in scientific modeling, simplifying assumptions permit illustration of concepts considered relevant to the inquiry. An example ...
