Wealth Effect
The wealth effect is the change in spending that accompanies a change in perceived wealth. Usually the wealth effect is positive: spending changes in the same direction as perceived wealth. Effect on individuals Changes in a consumer's wealth cause changes in the amounts and distribution of his or her consumption. People typically spend more overall when one of two things is true: when people ''actually are'' richer, objectively, or when people ''perceive themselves'' to be richer—for example, the assessed value of their home increases, or a stock they own goes up in price. Demand for some goods (called inferior goods) decreases with increasing wealth. For example, consider consumption of cheap fast food versus steak. As someone becomes wealthier, their demand for cheap fast food is likely to decrease, and their demand for more expensive steak may increase. Consumption may be tied to relative wealth. Particularly when supply is highly inelastic, or when the seller is a monopo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wealth
Wealth is the abundance of Value (economics), valuable financial assets or property, physical possessions which can be converted into a form that can be used for financial transaction, transactions. This includes the core meaning as held in the originating Old English word , which is from an Indo-European languages, Indo-European word stem. The modern concept of wealth is of significance in all areas of economics, and clearly so for economic growth, growth economics and development economics, yet the meaning of wealth is context-dependent. An individual possessing a substantial net worth is known as ''wealthy''. Net worth is defined as the current value of one's assets less liabilities (excluding the principal in trust accounts). At the most general level, economists may define wealth as "the total of anything of value" that captures both the subjective nature of the idea and the idea that it is not a fixed or static concept. Various definitions and concepts of wealth have been a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dean Baker
Dean Baker (born July 13, 1958) is an American macroeconomist who co-founded the Center for Economic and Policy Research (CEPR) with Mark Weisbrot. Baker has been credited as one of the first economists to have identified the 2007–08 United States housing bubble. Early life and education Baker grew up in the Lake View neighborhood of Chicago. In 1981, Baker graduated from Swarthmore College with a bachelor's degree in history with minors in economics and philosophy. In 1983, he received a master's degree in economics from the University of Denver. In 1988, he received a PhD from the University of Michigan in economics. Career Baker was a lecturer at the University of Michigan from 1988 to 1989 and an assistant professor of economics at Bucknell University from 1989 to 1992. From 1992 to 1998, he was an economist at the Economic Policy Institute. During this time, he published a paper with Mark Weisbrot in a journal of evolutionary economics. In 1999, Baker and Weisbrot co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wealth Elasticity Of Demand
{{Original research, date=January 2013 The wealth elasticity of demand, in microeconomics and macroeconomics, is the proportional change in the consumption of a good (economics), good relative to a change in consumers' Wealth (economics), wealth (as distinct from changes in personal income#Meaning in economics and use in economic theory, income). Measuring and accounting for the variability in this Elasticity (economics), elasticity is a continuing problem in behavioral finance and consumer theory. Definition The wealth Elasticity (economics), elasticity of consumption quantity for some good will determine the size of the expenditure shift due to ''unexpected'' changes in net personal wealth, ''ceteris paribus'' (i.e. the size of the so-called "wealth effect" for a given good). It is calculated as ''the ratio of the percent change in consumption to the percent change in wealth that caused it.'' This is analogous to the definition of the income effect from the income elasticity of d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ricardian Equivalence
The Ricardian equivalence proposition (also known as the Ricardo–de Viti–Barro equivalence theorem) is an economic hypothesis holding that consumers are forward-looking and so internalize the government's budget constraint when making their consumption decisions. This leads to the result that, for a given pattern of government spending, the method of financing such spending does not affect agents' consumption decisions, and thus, it does not change aggregate demand. Introduction Governments can finance their expenditures by creating new money, by levying taxes, or by issuing bonds. Since bonds are loans, they must eventually be repaid—presumably by raising taxes in the future. The choice is therefore "tax now or tax later." Suppose that the government finances some extra spending through deficits; i.e. it chooses to tax later. According to the hypothesis, taxpayers will anticipate that they will have to pay higher taxes in future. As a result, they will save, rather than spe ...

Money Illusion
In economics, money illusion, or price illusion, is a cognitive bias where money is thought of in nominal, rather than real terms. In other words, the face value (nominal value) of money is mistaken for its purchasing power (real value) at a previous point in time. Viewing purchasing power as measured by the nominal value is false, as modern fiat currencies have no intrinsic value and their real value depends purely on the price level. The term was coined by Irving Fisher in ''Stabilizing the Dollar''. It was popularized by John Maynard Keynes in the early twentieth century, and Irving Fisher wrote an important book on the subject, ''The Money Illusion'', in 1928. The existence of money illusion is disputed by monetary economists who contend that people act rationally (i.e. think in real prices) with regard to their wealth. Eldar Shafir, Peter A. Diamond, and Amos Tversky (1997) have provided empirical evidence for the existence of the effect and it has been shown to affect beha ...

Income Elasticity Of Demand
In economics, the income elasticity of demand is the responsivenesses of the quantity demanded for a good to a change in consumer income. It is measured as the ratio of the percentage change in quantity demanded to the percentage change in income. If a 10% increase in Mr. Ruskin Smith's income causes him to buy 20% more bacon, Smith's income elasticity of demand for bacon is 20%/10% = 2. * Mathematical definition :\epsilon_d = \frac The point elasticity version, which defines it as an instantaneous rate of change of quantity demanded as income changes, is as follows. For a given Marshallian demand function Q(I,\vec) , with arguments income and a vector of prices of all goods, :\epsilon_d = \frac\frac This can be rewritten in the form :\epsilon_d = \frac For discrete changes the elasticity is (using the arc elasticity) :\epsilon_d= \times =\times , where subscripts 1 and 2 refer to values before and after the change. Interpretation The most commonly used elastic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Income Effect
The theory of consumer choice is the branch of microeconomics that relates preferences to consumption expenditures and to consumer demand curves. It analyzes how consumers maximize the desirability of their consumption as measured by their preferences subject to limitations on their expenditures, by maximizing utility subject to a consumer budget constraint. Factors influencing consumers' evaluation of the utility of goods: income level, cultural factors, product information and physio-psychological factors. Consumption is separated from production, logically, because two different economic agents are involved. In the first case consumption is by the primary individual, individual tastes or preferences determine the amount of pleasure people derive from the goods and services they consume.; in the second case, a producer might make something that he would not consume himself. Therefore, different motivations and abilities are involved. The models that make up consumer theory are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aggregate Demand
In macroeconomics, aggregate demand (AD) or domestic final demand (DFD) is the total demand for final goods and services in an economy at a given time. It is often called effective demand, though at other times this term is distinguished. This is the demand for the gross domestic product of a country. It specifies the amount of goods and services that will be purchased at all possible price levels. Consumer spending, investment, corporate and government expenditure, and net exports make up the aggregate demand. The aggregate demand curve is plotted with real output on the horizontal axis and the price level on the vertical axis. While it is theorized to be downward sloping, the Sonnenschein–Mantel–Debreu results show that the slope of the curve cannot be mathematically derived from assumptions about individual rational behavior. Instead, the downward sloping aggregate demand curve is derived with the help of three macroeconomic assumptions about the functioning of markets: ...

Real And Nominal Variables
In economics, nominal value is measured in terms of money, whereas real value is measured against goods or services. A real value is one which has been adjusted for inflation, enabling comparison of quantities as if the prices of goods had not changed on average; therefore, changes in real value exclude the effect of inflation. In contrast, a nominal value has not been adjusted for inflation, and so changes in nominal value reflect at least in part the effect of inflation but will not hold the same purchasing power. Commodity bundles, price indices and inflation A commodity bundle is a sample of goods, which is used to represent the sum total of goods across the economy to which the goods belong, for the purpose of comparison across different times (or locations). At a single point of time, a commodity bundle consists of a list of goods, and each good in the list has a market price and a quantity. The market value of the good is the market price times the quantity at that poin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macroeconomics
Macroeconomics (from the Greek prefix ''makro-'' meaning "large" + ''economics'') is a branch of economics dealing with performance, structure, behavior, and decision-making of an economy as a whole. For example, using interest rates, taxes, and government spending to regulate an economy's growth and stability. This includes regional, national, and global economies. According to a 2018 assessment by economists Emi Nakamura and Jón Steinsson, economic "evidence regarding the consequences of different macroeconomic policies is still highly imperfect and open to serious criticism." Macroeconomists study topics such as Gross domestic product, GDP (Gross Domestic Product), unemployment (including Unemployment#Measurement, unemployment rates), national income, price index, price indices, output (economics), output, Consumption (economics), consumption, inflation, saving, investment (macroeconomics), investment, Energy economics, energy, international trade, and international finance. ...
