Marginal Product Of Labour
In economics, the marginal product of labor (MPL) is the change in output that results from employing an added unit of labor. It is a feature of the production function, and depends on the amounts of physical capital and labor already in use. Definition The marginal product of a factor of production is generally defined as the change in output resulting from a unit or infinitesimal change in the quantity of that factor used, holding all other input usages in the production process constant. The marginal product of labor is then the change in output (''Y'') per unit change in labor (''L''). In discrete terms the marginal product of labor is: : \frac . In continuous terms, the ''MPL'' is the first derivative of the production function: : \frac .Perloff, J., ''Microeconomics Theory and Applications with Calculus'', Pearson 2008. p. 173. Graphically, the ''MPL'' is the slope of the production function. Examples There is a factory which produces toys. When there are no workers ...

Output (economics)
Output in economics is the "quantity of goods or Service (economics), services Production (economics), produced in a given time period, by a firm, industry, or country", whether consumed or used for further production. The concept of national output is essential in the field of macroeconomics. It is national output that makes a country rich, not large amounts of money. Definition Output is the result of an economic process that has used input (economics), inputs to produce a product or service that is available for sale or use somewhere else. ''Net output'', sometimes called ''netput'' is a quantity, in the context of production, that is positive if the quantity is output by the production process and negative if it is an input to the production process. Microeconomics Output condition The profit-maximizing output condition for producers equates the relative marginal cost of any two goods to the relative selling price of those goods; i.e. \frac = \frac One may als ...

Marginal Product Of Capital
In economics, the marginal product of capital (MPK) is the additional production that a firm experiences when it adds an extra unit of capital. It is a feature of the production function, alongside the labour input. Definition The marginal product of capital (MPK) is the additional output resulting, ceteris paribus ("all things being equal"), from the use of an additional unit of physical capital, such as machines or buildings used by businesses. The marginal product of capital (MPK) is the amount of extra output the firm gets from an extra unit of capital, holding the amount of labor constant: : MP_K = F(K + 1, L) - F(K, L) Thus, the marginal product of capital is the difference between the amount of output produced with K + 1 units of capital and that produced with only K units of capital.N. Gregory Mankiw. (2010). Macroeconomics. United States: Worth Publishers Determining marginal product of capital is essential when a firm is debating on whether or not to invest on the ad ...

Karl Marx
Karl Heinrich Marx (; 5 May 1818 – 14 March 1883) was a German philosopher, economist, historian, sociologist, political theorist, journalist, critic of political economy, and socialist revolutionary. His best-known titles are the 1848 pamphlet ''The Communist Manifesto'' and the four-volume (1867–1883). Marx's political and philosophical thought had enormous influence on subsequent intellectual, economic, and political history. His name has been used as an adjective, a noun, and a school of social theory. Born in Trier, Germany, Marx studied law and philosophy at the universities of Bonn and Berlin. He married German theatre critic and political activist Jenny von Westphalen in 1843. Due to his political publications, Marx became stateless and lived in exile with his wife and children in London for decades, where he continued to develop his thought in collaboration with German philosopher Friedrich Engels and publish his writings, researching in the British Mus ...

Labor Theory Of Value
The labor theory of value (LTV) is a theory of value that argues that the economic value of a good or service is determined by the total amount of " socially necessary labor" required to produce it. The LTV is usually associated with Marxian economics, although it originally appeared in the theories of earlier classical economists such as Adam Smith and David Ricardo, and later in anarchist economics. Smith saw the price of a commodity in terms of the labor that the purchaser must expend to buy it, which embodies the concept of how much labor a commodity, a tool for example, can save the purchaser. The LTV is central to Marxist theory, which holds that the working class is exploited under capitalism, and dissociates price and value. However, Marx did not refer to his own theory of value as a "labour theory of value". Orthodox neoclassical economics rejects the LTV, using a theory of value based on subjective preferences. The revival in interpretation of Marx known as the also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Elsie Elizabeth (Hungler) and Joseph Stigler. He was of German descent and spoke German in his childhood. He graduated from the University of Washington in 1931 with a BA 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. 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 there in 1938. He taught at Iowa State College from 1936 to 1938. He spent much of World War II at Columbia University, performi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Austrian School
The Austrian School is a heterodox school of economic thought that advocates strict adherence to methodological individualism, the concept that social phenomena result exclusively from the motivations and actions of individuals. Austrian school theorists hold that economic theory should be exclusively derived from basic principles of human action.Ludwig von Mises. Human Action, p. 11, "Purposeful Action and Animal Reaction". Referenced 2011-11-23. The Austrian School originated in late-19th- and early-20th-century Vienna with the work of Carl Menger, Eugen von Böhm-Bawerk, Friedrich von Wieser, and others. It was methodologically opposed to the Historical School (based in Germany), in a dispute known as ''Methodenstreit'', or methodology struggle. Current-day economists working in this tradition are located in many different countries, but their work is still referred to as Austrian economics. Among the theoretical contributions of the early years of the Austrian School are the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
