Lucas Aggregate Supply Function
The Lucas aggregate supply function or Lucas "surprise" supply function, based on the Lucas imperfect information model, is a representation of aggregate supply based on the work of New classical macroeconomics, new classical economist Robert Lucas, Jr., Robert Lucas. The model states that economic output is a function of money or price "surprise". The model accounts for the empirically based trade off between output and prices represented by the Phillips curve, but the function breaks from the Phillips curve since only unanticipated price level changes lead to changes in output. The model accounts for empirically observed short-run correlations between output and prices, but maintains the neutrality of money (the absence of a price or money supply relationship with output and employment) in the long-run. The Policy Ineffectiveness Proposition, policy ineffectiveness proposition extends the model by arguing that, since people with rational expectations cannot be systematically sur ...

Aggregate Supply
In economics, aggregate supply (AS) or domestic final supply (DFS) is the total supply of goods and services that firms in a national economy plan on selling during a specific time period. It is the total amount of goods and services that firms are willing and able to sell at a given price level in an economy. Analysis There are two main reasons why the amount of aggregate output supplied might rise as price level ''P'' rises, i.e., why the ''AS'' curve is upward sloping: * The short-run ''AS'' curve is drawn given some nominal variables such as the nominal wage rate, which is assumed fixed in the ''short run''. Thus, a higher price level ''P'' implies a lower real wage rate and thus an incentive to produce more output. In the neoclassical ''long run'', on the other hand, the nominal wage rate varies with economic conditions. (High unemployment leads to falling nominal wages which restore full employment.) Hence, in the long run, the aggregate supply curve is vertical. * An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Sargent
Thomas John Sargent (born July 19, 1943) is an American economist and the W.R. Berkley Professor of Economics and Business at New York University.

Okun's Law
In economics, Okun's law is an empirically observed relationship between unemployment and losses in a country's production. It is named after Arthur Melvin Okun, who first proposed the relationship in 1962. The "gap version" states that for every 1% increase in the unemployment rate, a country's GDP will be roughly an additional 2% lower than its potential GDP. The "difference version" describes the relationship between quarterly changes in unemployment and quarterly changes in real GDP. The stability and usefulness of the law has been disputed. Imperfect relationship Okun's law may more accurately be called "Okun's rule of thumb" because it is an approximation based on empirical observation rather than a result derived from theory. Okun's law is approximate because factors other than employment, such as productivity, affect output. In Okun's original statement of his law, a 2% increase in output corresponds to a 1% decline in the rate of cyclical unemployment; a 0.5% increase ...

Potential Output
In economics, potential output (also referred to as "natural gross domestic product") refers to the highest level of real gross domestic product (potential output) that can be sustained over the long term. Actual output happens in real life while potential output shows the level that could be achieved. Limits to output Natural (physical, etc) and institutional constraints impose limits to growth. If actual GDP rises and stays above potential output, then, in a free market economy (i.e. in the absence of wage and price controls), inflation tends to increase as demand for factors of production exceeds supply. This is because of the finite supply of workers and their time, of capital equipment, and of natural resources, along with the limits of our technology and our management skills. Graphically, the expansion of output beyond the natural limit can be seen as a shift of production volume above the optimum quantity on the average cost curve. Likewise, if GDP persists below natural G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relative Price
A relative price is the price of a commodity such as a good or service in terms of another; i.e., the ratio of two prices. A relative price may be expressed in terms of a ratio between the prices of any two goods or the ratio between the price of one good and the price of a market basket of goods (a weighted average of the prices of all other goods available in the market). Microeconomics can be seen as the study of how economic agents react to changes in relative prices, and of how relative prices are affected by the behavior of those agents. The difference and change of relative prices can also reflect the development of productivity. In a demand equation In the demand equation Q=f(P) (in which Q is the number of units of a good or service demanded), P is the relative price of the good or service rather than the nominal price. It is the change in a relative price that prompts a change in the quantity demanded. For example, if all prices rise by 10% there is no change in any r ...

Shock (economics)
In economics, a shock is an unexpected or unpredictable event that affects an economy, either positively or negatively. Technically, it is an unpredictable change in exogenous factors—that is, factors unexplained by an economic model—which may influence endogenous economic variables. The response of economic variables, such as GDP and employment, at the time of the shock and at subsequent times, is measured by an impulse response function. Types of shocks A technology shock is the kind resulting from a technological development that affects productivity. If the shock is due to constrained supply, it is termed a supply shock and usually results in price increases for a particular product. Supply shocks can be produced when accidents or disasters occur. The 2008 Western Australian gas crisis resulting from a pipeline explosion at Varanus Island is one example. A demand shock is a sudden change of the pattern of private expenditure, especially of consumption spending by cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward C
Edward is an English given name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy and Ned. ...

Real Business Cycle Theory
Real business-cycle theory (RBC theory) is a class of new classical macroeconomics models in which business-cycle fluctuations are accounted for by real (in contrast to nominal) shocks. Unlike other leading theories of the business cycle, RBC theory sees business cycle fluctuations as the efficient response to exogenous changes in the real economic environment. That is, the level of national output necessarily maximizes ''expected'' utility, and governments should therefore concentrate on long-run structural policy changes and not intervene through discretionary fiscal or monetary policy designed to actively smooth out economic short-term fluctuations. According to RBC theory, business cycles are therefore "real" in that they do not represent a failure of markets to clear but rather reflect the most efficient possible operation of the economy, given the structure of the economy. RBC theory is associated with freshwater economics (the Chicago School of Economics in the neoclas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neil Wallace
Neil Wallace (born 1939) is an American economist and professor of economics at Penn State University. He is considered one of the main proponents of new classical macroeconomics in the field of economics. Education Wallace earned his BA in economics from Columbia University in 1960 and his Ph.D in economics from the University of Chicago in 1964, where he studied under Nobel Prize-winning economist Milton Friedman. Career In 1969, Wallace was hired as a consultant to the Federal Reserve Bank of Minneapolis.

Natural Rate Hypothesis
The natural rate of unemployment is the name that was given to a key concept in the study of economic activity. Milton Friedman and Edmund Phelps, tackling this 'human' problem in the 1960s, both received the Nobel Memorial Prize in Economic Sciences for their work, and the development of the concept is cited as a main motivation behind the prize. A simplistic summary of the concept is: 'The natural rate of unemployment, when an economy is in a steady state of "full employment", is the proportion of the workforce who are unemployed'. Put another way, this concept clarifies that the economic term "full employment" does not mean "zero unemployment". It represents the hypothetical unemployment rate consistent with aggregate production being at the "long-run" level. This level is consistent with aggregate production in the absence of various temporary frictions such as incomplete price adjustment in labor and goods markets. The natural rate of unemployment therefore corresponds to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Classical Macroeconomics
New classical macroeconomics, sometimes simply called new classical economics, is a school of thought in macroeconomics that builds its analysis entirely on a neoclassical economics, neoclassical framework. Specifically, it emphasizes the importance of rigorous foundations based on microeconomics, especially rational expectations. New classical macroeconomics strives to provide neoclassical microeconomic foundations for macroeconomic analysis. This is in contrast with its rival New Keynesian economics, new Keynesian school that uses microfoundations such as Sticky (economics), price stickiness and imperfect competition to generate macroeconomic models similar to earlier, Keynesian ones. History Classical economics is the term used for the first modern school of economics. The publication of Adam Smith's ''The Wealth of Nations'' in 1776 is considered to be the birth of the school. Perhaps the central idea behind it is on the ability of the market to be self-correcting as well a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
