Average Propensity To Consume
Average propensity to consume (as well as the marginal propensity to consume) is a concept developed by John Maynard Keynes to analyze the consumption function, which is a formula where total consumption expenditures (C) of a household consist of autonomous consumption (Ca) and income (Y) (or disposable income (YD)) multiplied by marginal propensity to consume (c or MPC). According to Keynes, the individual´s real income determines saving and consumption decisions. Consumption function: C=+cY The average propensity to consume is referred to as the percentage of income spent on goods and services. It is the proportion of income that is consumed and it is calculated by dividing total consumption expenditure (C) by total income (Y): APC=\frac=\frac+c It can be also explained as spending on every monetary unit of income. Moreover Keynes´s theory claims that wealthier people spend less of their income on consumption than less wealthy people. This is caused by autonomous consumptio ...

Marginal Propensity To Consume
In economics, the marginal propensity to consume (MPC) is a metric that quantifies induced consumption, the concept that the increase in personal consumer spending (consumption) occurs with an increase in disposable income (income after taxes and transfers). The proportion of disposable income which individuals spend on consumption is known as propensity to consume. MPC is the proportion of additional income that an individual consumes. For example, if a household earns one extra dollar of disposable income, and the marginal propensity to consume is 0.65, then of that dollar, the household will spend 65 cents and save 35 cents. Obviously, the household cannot spend ''more'' than the extra dollar (without borrowing or using savings). If the extra money accessed by the individual gives more economic confidence, then the MPC of the individual may well exceed 1, as they may borrow or utilise savings. The MPC is higher in the case of poorer people than in rich. According to John Mayna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Average Propensity To Save
In Keynesian economics, the average propensity to save (APS), also known as the savings ratio, is the proportion of income which is saved, usually expressed for household savings as a fraction of total household disposable income (taxed income). APS=\frac The ratio differs considerably over time and between countries. The savings ratio for an entire economy can be affected by (for example) the proportion of older people (as they have less motivation and capability to save), and the rate of inflation (as expectations of rising prices can encourage people to spend now rather than later) or current interest rates. APS can express the social preference for investing in the future over consuming in the present. The complement (1 minus the APS) is the average propensity to consume (APC). Low average propensity to save might be the indicator of a large percentage of old people or high percentage of irresponsible young people in the population. With income level changes, APS becomes an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marginal Propensity To Save
The marginal propensity to save (MPS) is the fraction of an increase in income that is not spent and instead used for saving. It is the slope of the line plotting saving against income. For example, if a household earns one extra dollar, and the marginal propensity to save is 0.35, then of that dollar, the household will spend 65 cents and save 35 cents. Likewise, it is the fractional decrease in saving that results from a decrease in income. The MPS plays a central role in Keynesian economics as it quantifies the saving-income relation, which is the flip side of the consumption-income relation, and according to Keynes it reflects the fundamental psychological law. The marginal propensity to save is also a key variable in determining the value of the multiplier. Calculation MPS can be calculated as the change in savings divided by the change in income. :MPS=\frac Or mathematically, the marginal propensity to save (MPS) function is expressed as the derivative of the savings ( ...

Milton Friedman
Milton Friedman (; July 31, 1912 – November 16, 2006) was an American economist and statistician who received the 1976 Nobel Memorial Prize in Economic Sciences for his research on consumption analysis, monetary history and theory and the complexity of stabilization policy. With George Stigler and others, Friedman was among the intellectual leaders of the Chicago school of economics, a neoclassical school of economic thought associated with the work of the faculty at the University of Chicago that rejected Keynesianism in favor of monetarism until the mid-1970s, when it turned to new classical macroeconomics heavily based on the concept of rational expectations. Several students, young professors and academics who were recruited or mentored by Friedman at Chicago went on to become leading economists, including Gary Becker, Robert Fogel, Thomas Sowell and Robert Lucas Jr. Friedman's challenges to what he called "naive Keynesian theory" began with his interpretation ...

Permanent Income Hypothesis
The permanent income hypothesis (PIH) is a model in the field of economics to explain the formation of consumption patterns. It suggests consumption patterns are formed from future expectations and consumption smoothing. The theory was developed by Milton Friedman and published in his ''A Theory of Consumption Function'', published in 1957 and subsequently formalized by Robert Hall in a rational expectations model. Originally applied to consumption and income, the process of future expectations is thought to influence other phenomena. In its simplest form, the hypothesis states changes in permanent income (human capital, property, assets), rather than changes in temporary income (unexpected income), are what drive changes in consumption. The formation of consumption patterns opposite to predictions was an outstanding problem faced by the Keynesian orthodoxy. Friedman's predictions of consumption smoothing, where people spread out transitory changes in income over time, departe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Life Cycle Hypothesis
In economics, the life-cycle hypothesis (LCH) is a model that strives to explain the consumption patterns of individuals. Background The hypothesis Implications Saving and wealth when income and population are stable The effect of population growth The effect of productivity growth Theory and evidence Elderly dissaving is also influenced by the present factors that materially prevent them form the possibility of spending their previous savings. One of them is the loss of the driving license. An extended survey held in 1998, 2000, and 2002 among the U.S. retired citizens highlighted that "about 90% of the trips among people older than age 65 are in a private vehicle" and that driving cessation was highly correlated (46% to 63%, Tobit regression) to a reduction in spending on non basic needs such as trips, tickets, and dinings out. It is also relevant to distinguish elderly poor people in two basic tipologies: people who are poor on income, or those who are poor in terms of b ...

Intertemporal Choice
Intertemporal choice is the process by which people make decisions about what and how much to do at various points in time, when choices at one time influence the possibilities available at other points in time. These choices are influenced by the relative value people assign to two or more payoffs at different points in time. Most choices require decision-makers to trade off costs and benefits at different points in time. These decisions may be about saving, work effort, education, nutrition, exercise, health care and so forth. Greater preference for immediate smaller rewards has been associated with many negative outcomes ranging from lower salary to drug addiction. Since early in the twentieth century, economists have analyzed intertemporal decisions using the discounted utility model, which assumes that people evaluate the pleasures and pains resulting from a decision in much the same way that financial markets evaluate losses and gains, exponentially 'discounting' the value of ...

Irving Fisher
Irving Fisher (February 27, 1867 – April 29, 1947) was an American economist, statistician, inventor, eugenicist and progressive social campaigner. He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the post-Keynesian school. Joseph Schumpeter described him as "the greatest economist the United States has ever produced", an assessment later repeated by James Tobin and Milton Friedman.Milton Friedman, ''Money Mischief: Episodes in Monetary History'', Houghton Mifflin Harcourt (1994) p. 37. Fisher made important contributions to utility theory and general equilibrium. He was also a pioneer in the rigorous study of intertemporal choice in markets, which led him to develop a theory of capital and interest rates. His research on the quantity theory of money inaugurated the school of macroeconomic thought known as "monetarism". Fisher was also a pioneer of econometrics, including the development of index nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Maynard Keynes
John Maynard Keynes, 1st Baron Keynes, ( ; 5 June 1883 – 21 April 1946), was an English economist whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. Originally trained in mathematics, he built on and greatly refined earlier work on the causes of business cycles. One of the most influential economists of the 20th century, he produced writings that are the basis for the school of thought known as Keynesian economics, and its various offshoots. His ideas, reformulated as New Keynesianism, are fundamental to mainstream macroeconomics. Keynes's intellect was evident early in life; in 1902, he gained admittance to the competitive mathematics program at King's College at the University of Cambridge. During the Great Depression of the 1930s, Keynes spearheaded a revolution in economic thinking, challenging the ideas of neoclassical economics that held that free markets would, in the short to medium term, a ...
