Deadweight Loss
In economics, deadweight loss is the loss of societal economic welfare due to production/consumption of a good at a quantity where marginal benefit (to society) does not equal marginal cost (to society). In other words, there are either goods being produced despite the cost of doing so being larger than the benefit, or additional goods are not being produced despite the fact that the benefits of their production would be larger than the costs. The deadweight loss is the net benefit that is missed out on. While losses to one entity often lead to gains for another, deadweight loss represents the loss that is not regained by anyone else. This loss is therefore attributed to both producers and consumers. Deadweight loss can also be a measure of lost economic efficiency when the socially optimal quantity of a good or a service is not produced. Non-optimal production can be caused by monopoly pricing in the case of artificial scarcity, a positive or negative externality, a tax or s ...

Sin Tax
A sin tax (also known as a sumptuary tax, or vice tax) is an excise tax specifically levied on certain goods deemed harmful to society and individuals, such as Alcohol tax, alcohol, tobacco tax, tobacco, drugs, candy, soft drinks, fast foods, coffee, sugar, gambling, vaping, cannabis (wherever legal for recreational use) and pornography. In contrast to Pigovian taxes, which are to pay for the damage to society caused by these goods, sin taxes increase the price in an effort to decrease the use of these goods. Increasing a sin tax is often more popular than increasing other taxes. However, these taxes have often been criticized for regressive tax, burdening the poor and disproportionately taxing the physically and mentally dependent. Summary The enactment of sin taxes on harmful activities varies by jurisdiction. In many cases, sumptuary taxes are implemented to mitigate use of alcohol and tobacco, gambling, and vehicles emitting excessive pollutants. Sumptuary tax on sugar and s ...

Elasticity (economics)
In economics, elasticity measures the responsiveness of one economic variable to a change in another. For example, if the price elasticity of the demand of a good is −2, then a 10% increase in price will cause the quantity demanded to fall by 20%. Elasticity in economics provides an understanding of changes in the behavior of the buyers and sellers with price changes. There are two types of elasticity for demand and supply, one is inelastic demand and supply and the other one is elastic demand and supply. Introduction The concept of price elasticity was first cited in an informal form in the book ''Principles of Economics (Marshall book), Principles of Economics'' published by the author Alfred Marshall in 1890. Subsequently, a major study of the price elasticity of supply and the price elasticity of demand for US products was undertaken by Joshua Levy and Trevor Pollock in the late 1960s. Elasticity is an important concept in neoclassical economic theory, and enables in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consumer Surplus
In mainstream economics, economic surplus, also known as total welfare or total social welfare or Marshallian surplus (after Alfred Marshall), is either of two related quantities: * Consumer surplus, or consumers' surplus, is the monetary gain obtained by consumers because they are able to purchase a product for a price that is less than the highest price that they would be willing to pay. * Producer surplus, or producers' surplus, is the amount that producers benefit by selling at a market price that is higher than the least that they would be willing to sell for; this is roughly equal to profit (since producers are not normally willing to sell at a loss and are normally indifferent to selling at a break-even price). The sum of consumer and producer surplus is sometimes known as social surplus or total surplus; a decrease in that total from inefficiencies is called deadweight loss.

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 ...

Marshallian Demand Function
In microeconomics, a consumer's Marshallian demand function (named after Alfred Marshall) is the quantity they demand of a particular good as a function of its price, their income, and the prices of other goods, a more technical exposition of the standard demand function. It is a solution to the utility maximization problem of how the consumer can maximize their utility for given income and prices. A synonymous term is uncompensated demand function, because when the price rises the consumer is not compensated with higher nominal income for the fall in their real income, unlike in the Hicksian demand function. Thus the change in quantity demanded is a combination of a substitution effect and a wealth effect. Although Marshallian demand is in the context of partial equilibrium theory, it is sometimes called Walrasian demand as used in general equilibrium theory (named after Léon Walras). According to the utility maximization problem, there are L commodities with price vector p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Hicks
Sir John Richard Hicks (8 April 1904 – 20 May 1989) was a British economist. He is considered one of the most important and influential economists of the twentieth century. The most familiar of his many contributions in the field of economics were his statement of consumer demand theory in microeconomics, and the IS–LM model (1937), which summarised a Keynesian view of macroeconomics. His book '' Value and Capital'' (1939) significantly extended general-equilibrium and value theory. The compensated demand function is named the Hicksian demand function in memory of him. In 1972 he received the Nobel Memorial Prize in Economic Sciences (jointly) for his pioneering contributions to general equilibrium theory and welfare theory. Early life Hicks was born in 1904 in Warwick, England, and was the son of Edward Hicks, editor and part proprietor of the Warwick and Leamington Spa Courier newspaper, and Dorothy Catherine, née Stephens, daughter of a non-conformist minister ...

Hicksian Demand Function
In microeconomics, a consumer's Hicksian demand function (or compensated demand function) represents the quantity of a good demanded when the consumer minimizes expenditure while maintaining a fixed level of utility. The Hicksian demand function illustrates how a consumer would adjust their demand for a good in response to a price change, assuming their income is adjusted (or compensated) to keep them on the same indifference curve—ensuring their utility remains unchanged. Mathematically, :h(p, \bar) = \arg \min_x \sum_i p_i x_i : \ \ u(x) \geq \bar . where h(p,u) is the Hicksian demand function or commodity bundle demanded, at price vector p and utility level \bar. Here p is a vector of prices, and x is a vector of quantities demanded, so the sum of all p_ix_i is the total expenditure on all goods. The Hicksian demand function isolates the effect of relative prices on demand, assuming utility remains constant. It contrasts with the Marshallian demand function, which acco ...

James Tobin
James Tobin (March 5, 1918 – March 11, 2002) was an American economist who served on the Council of Economic Advisers and consulted with the Board of Governors of the Federal Reserve System, and taught at Harvard University, Harvard and Yale University, Yale Universities. He contributed to the development of key ideas in the Keynesian economics of his generation and advocated government intervention in particular to stabilize output and avoid recessions. His academic work included pioneering contributions to the study of investment (macroeconomics), investment, monetary and fiscal policy and financial markets. He also proposed an econometric model for Censoring (statistics), censored dependent variables, the well-known tobit model. Along with fellow Neo-Keynesian economics, neo-Keynesian economist James Meade in 1977, Tobin proposed Nominal income target, nominal GDP targeting as a Discretionary policy, monetary policy rule in 1980. Tobin received the Nobel Memorial Prize in Econ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Indicator
An economic indicator is a statistic about an Economics, economic activity. Economic indicators allow analysis of economic performance and predictions of future performance. One application of economic indicators is the study of business cycles. Economic indicators include various indices, earnings reports, and economic summaries: for example, the unemployment rate, quits rate (quit rate in American English), housing starts, consumer price index (a measure for inflation (economics), inflation), inverted yield curve, consumer leverage ratio, industrial production, bankruptcies, gross domestic product, broadband internet access, broadband internet penetration, retail sales, price index, and changes in credit conditions. The leading business cycle dating committee in the United States, United States of America is the private National Bureau of Economic Research. The Bureau of Labor Statistics is the principal fact-finding agency for the U.S. government in the field of labor economics ...

Martin Feldstein
Martin Stuart Feldstein ( ; November 25, 1939 – June 11, 2019) was an American economist. He was the George F. Baker Professor of Economics at Harvard University and the president emeritus of the National Bureau of Economic Research. He served as president and chief executive officer of the bureau from 1978 to 2008 (with the exception of 1982 to 1984). From 1982 to 1984, Feldstein served as chairman of the Council of Economic Advisers and as chief economic advisor to President Ronald Reagan (where his deficit hawk views clashed with the Reagan administration's large military expenditure policies). Feldstein was also a member of the Washington-based financial advisory body the Group of Thirty from 2003. Early life and education Feldstein was born in New York City to a Jewish family and graduated from South Side High School in Rockville Centre, New York. He completed his undergraduate education at Harvard University ( BA, ''summa cum laude'', 1961), where he was affiliate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tax Wedge
The tax wedge is the deviation from the equilibrium price and quantity (P^* and Q^*, respectively) as a result of the taxation of a good. Because of the tax, consumers pay more for the good (P_c) than they did before the tax, and suppliers receive less for the good (P_s) than they did before the tax . Put differently, the tax wedge is the difference between the price consumers pay and the value producers receive (net of tax) from a transaction. The tax effectively drives a "wedge" between the price consumers pay and the price producers receive for a product. Following the Law of Supply and Demand, as the price to consumers increases, and the price received by suppliers decreases, the quantity that each wishes to trade will decrease. After a tax is introduced, a new equilibrium is reached, where consumers pay more (P^* \rightarrow P_c), suppliers receive less (P^* \rightarrow P_s), and the quantity exchanged falls (Q^* \rightarrow Q_t). The difference between P_c and P_s will be e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
