A central conclusion of Keynesian economics is that there is no strong automatic tendency for output and employment to move toward In economics, full employment has more than one meaning.

Historical background

John Maynard Keynes was one of a wave of thinkers who perceived increasing cracks in the assumptions and theories which held sway at that time. As physics questioned the necessity of absolute time, writers the structured narrative, and composers the need for tonal harmony -- Keynes questioned two of the pillars of economic theory dominant: the need for a solid basis for money, generally a This article is on the monetary principle.

However, he neither had proof, nor a formalism to express these ideas.

Into this void stepped Keynes, promising not to institute revolution but to save capitalism. He circulated a simple thesis: there were more factories and transportation networks than could be used at the current ability of individuals to pay and that the problem was on the demand side.

But many economists still insisted that business confidence, not lack of demand, was the root of the problem, and that the correct course was to slash government expenditures and to cut wages to raise business confidence and willingness to hire unemployed workers. Yet others simply argued that "nature would take its course," solving the Depression automatically by "shaking out" unneeded productive capacity.

Keynes and the Classics

Keynes explained the level of output and employment in the economy as being determined by aggregate demand or Effective demand (in macroeconomics often seen as synonymous with aggregate demand), refers to the very simple economic idea that says that its not enough to want something such as food or luxuries. One must also have money or other assets (purchasing power) or some product to sell in order... effective demand. In a reversal of Say's Law, Keynes in essence argued that "demand creates its own supply," up to the limit set by In economics, full employment has more than one meaning. To many laypeople, it means zero unemployment or underemployment. To economists, it means the lowest level of unemployment that can be sustained given the structure of the economy. In standard macroeconomics, when unemployment equals the NAIRU the real gross domestic product... full employment.

In "classical" economic theory -- Keynes's term for the economics prior to General Theory (and specifically that of Arthur Cecil Pigou (November 18, 1877 _ March 7, 1959) was an English economist, known for his work in many fields and particularly in welfare economics. He was a graduate of Kings College, Cambridge, where he studied under Alfred Marshall. He later succeeded Marshall as professor of political economy... Arthur Pigou) -- adjustments in prices would automatically make demand tend to the In economics, full employment has more than one meaning. To many laypeople, it means zero unemployment or underemployment. To economists, it means the lowest level of unemployment that can be sustained given the structure of the economy. In standard macroeconomics, when unemployment equals the NAIRU the real gross domestic product... full employment level. Keynes, pointing to the sharp fall in employment and output in the early 1930s, argued that whatever the theory, this self-correcting process had not happened.

In the neo-classical theory, the two main costs are those of labor and money. If there was more labor than demand for it, wages would fall until hiring began again. If there was too much saving, and not enough consumption, then interest rates would fall until either people cut saving or started borrowing. These two price adjustments would always enforce Say's Law, and therefore the economy would be at the optimal level of output.

Wages and spending

Even in the worst years of the Depression, the classical theory defined economic collapse as simply a lost incentive to produce. Mass Unemployment rates in the United States. In economics, a person who is able and willing to work yet is unable to find a paying job is considered unemployed. The unemployment rate is the number of unemployed workers divided by the total civilian labor force, which includes both the unemployed and... unemployment was caused only by high and rigid real wages. The proper solution was to cut wages.

To Keynes, the determination of wages is more complicated. First, he argued that it is not In economics, the distinction between nominal and real numbers is often made. It corresponds to the distinction between money and inflation-corrected numbers. Nominal numbers - such as nominal wages, interest rates and gross domestic product (GDP) - refer to amounts that are paid or earned in money terms. A paycheck shows... real but nominal wages that are set in negotiations between employers and workers. It's not a Barter is a simple form of trade where goods or services are exchanged for a certain amount of other goods or services, i.e. there is no money involved in the transaction. Barter trade was common in societies where no monetary system existed or in economies suffering from a very... barter relationship. First, nominal wage cuts would be difficult to put into effect because of laws and wage contracts. Even classical economists admitted that these exist; unlike Keynes, they advocated abolishing minimum wages, unions, and long-term contracts, increasing labor-market flexibility. However, to Keynes, people will resist nominal wage reductions, even without unions, until they see other wages falling and a general fall of prices.

He also argued that to boost employment, real wages had to go down: nominal wages would have to fall more than prices. However, doing so would reduce In Keynesian economics consumption refers to personal consumption expenditure, i.e., the purchase of currently produced goods and services out of income, out of savings (net worth), or from borrowed funds. It refers to that part of disposable income (income after taxes paid and transfer payments received) that does not... consumer demand, so that the In economics, aggregate demand is the total demand for goods and services in the economy (Y) during a specific time period. It is often called effective demand. Put another way, it is the demand for the gross domestic product of a country (the total new production sold through the market... aggregate demand for goods would drop. This would in turn reduce business sales revenues and expected profits. Investment in new plant and equipment -- perhaps already discouraged by previous excesses -- would then become more risky, less likely. Instead of raising business expectations, wages cuts could make matters much worse.

Further, if wages and prices were falling, people would start to expect them to fall. This could make the economy spiral downward as those who had money would simply wait as falling prices made it more valuable -- rather than spending. As Irving Fisher (February 27, 1867 Saugerties, New York — April 29, 1947, New York) was one of the earliest American Neoclassical economists. He is one of the early propents of price indexes, and is credited with proposing the Phillips curve, the indifference curve, International Fisher Effect and the Fisher separation... Irving Fisher argued in 1933, in his Debt-Deflation Theory of Great Depressions, ( In economics, deflation is a decrease in the general price level, or a rise in the purchasing power of money with respect to a large class of goods or services. Inflation is the opposite of deflation. Deflation should not be confused with disinflation which is a slowing in the rate... falling prices) can make a depression deeper as falling prices and wages made pre-existing nominal debts more valuable in real terms.

To Keynes, excessive saving, i.e. saving beyond planned investment, was a serious problem encouraging A recession is usually defined in macroeconomics as a fall of a countrys Gross National Product in two successive quarters.

Excessive saving results if investment falls, perhaps due to falling consumer demand, over-investment in earlier years, or pessimistic business expectations, and if saving does not immediately fall in step.

The Economics is the social science studying production and consumption through measurable variables. It involves analysing the production, distribution, trade and consumption of goods and services. Economics is said to be positive when it attempts to explain the consequences of different choices given a set of assumptions and normative when it... classical economists argued that interest rates would fall due to the excess supply of "loanable funds." The first diagram, adapted from the only graph in The General Theory, shows this process. (For simplicity, other sources of the demand for or supply of funds are ignored here.) Assume that fixed investment in plant and equipment falls from "old I" to "new I" (step a). Second (step b), the resulting excess of saving causes interest-rate cuts, abolishing the excess supply: so again we have saving (S) equal to investment. The interest-rate fall prevents that of production and employment.

Keynes had a complex argument against this Laissez-faire is short for laissez faire, laissez passer, a French phrase meaning to let things alone, let them pass. First used by the eighteenth century Physiocrats as an injunction against government interference with trade, it is now used as a synonym for strict free market economics. Laissez-faire economic... laissez-faire response. The graph below summarizes his argument, assuming again that fixed investment falls (step A). First, saving does not fall much as interest rates fall, since the Consumer theory relates preferences, indifference curves and budget constraints to consumer demand curves.

Second, since planned Fixed investment in economics refers to an increase in the amounts of real capital goods (real means of production) used in production or to the replacement of depreciated capital goods. Thus, fixed investment would increase the amount of factories, machines, tools, housing, office buildings, and other structures available -- or deal... fixed investment in plant and equipment is mostly based on long-term expectations of future profitability, that spending does not rise much as interest rates fall. So S and I are drawn as steep (inelastic) in the graph. Given the In economics, elasticity is the ratio of the incremental percentage change in one variable with respect to an incremental percentage change in another variable. Elasticity is usually expressed as a (positive) absolute value when the sign is already clear from context. Contents // 1 Generalised cases 2 Mathematical definition 3 Importance... inelasticity of both demand and supply, a large interest-rate fall is needed to close the saving/investment gap. As drawn, this requires a negative interest rate at equilibrium (where the new I line would intersect the old S line). However, this negative interest rate is not necessary to Keynes's argument.

Third, Keynes argued that saving and investment are not the main determinants of interest rates, especially in the short run. Instead, the supply of and the demand for the stock of Moneys is an agreement within a community, to use something as a medium of exchange, which acts as an intermediary market good. It can be traded and exchanged for other goods. The agreement can either be explicit or implicit, freely chosen, or coerced. Money is an abstract form of power... money determine interest rates in the short run. (This is not drawn in the graph.) Neither change quickly in response to excessive saving to allow fast interest-rate adjustment.

Finally, because of fear of capital losses on assets besides money, Keynes suggested that there may be a " In economics, a liquidity trap is a situation when the economy is stagnant and the interest rate is equal to, or slightly above, 0 percent. In this kind of situation, people do not expect high returns on their financial or real investments and so keep their money on their bank... liquidity trap" setting a floor under which interest rates cannot fall. (In this trap, bond-holders, fearing rises in interest rates (because rates are so low), fear capital losses on their bonds and thus try to sell them to attain money (liquidity).) Even economists who reject this liquidity trap now realize that In economics, the distinction between nominal and real numbers is often made. It corresponds to the distinction between money and inflation-corrected numbers. Nominal numbers - such as nominal wages, interest rates and gross domestic product (GDP) - refer to amounts that are paid or earned in money terms. A paycheck shows... nominal interest rates cannot fall below zero (or slightly higher). In the diagram, the equilibrium suggested by the new I line and the old S line cannot be reached, so that excess saving persists. Some (such as The zero interest rate policy (ZIRP) is a macroeconomics scheme devised by economist Paul Krugman for economies exhibiting slow growth with a very low interest rate, such as contemporary Japan.

Japan in the 1990s.

Even if this "trap" does not exist, there is a fourth element to Keynes's critique (perhaps the most important part). Saving involves not spending all of one's income. It thus means insufficient demand for business output, unless it is balanced by other sources of demand, such as fixed investment. Thus, excessive saving corresponds to an unwanted accumulation of inventories, or what classical economists called a "general glut (http://cepa.newschool.edu/het/essays/classic/glut.htm)". This pile-up of unsold goods and materials encourages businesses to decrease both production and employment. This in turn lowers people's incomes -- and saving, causing a leftward shift in the S line in the diagram (step B). For Keynes, the fall in income did most of the job ending excessive saving and allowing the loanable funds market to attain equilibrium. Instead of interest-rate adjustment solving the problem, a A recession is usually defined in macroeconomics as a fall of a countrys Gross National Product in two successive quarters. (This is a simplified version of that of the business-cycle dating committee of the National Bureau for Economic Research, a U.S.-based think tank.) Combined with inflation... recession does so. Thus in the diagram, the interest-rate change is small.

Whereas the classical economists assumed that the level of output and income was constant and given at any one time (except for short-lived deviations), Keynes saw this as the key variable that adjusted to equate saving and investment.

Finally, a recession undermines the business incentive to engage in Fixed investment in economics refers to an increase in the amounts of real capital goods (real means of production) used in production or to the replacement of depreciated capital goods. Thus, fixed investment would increase the amount of factories, machines, tools, housing, office buildings, and other structures available -- or deal... fixed investment. With falling incomes and demand for products, the desired demand for factories and equipment (not to mention housing) will fall.

This recreates the problem of excessive saving and encourages the recession to continue.

In sum, to Keynes there is interaction between excess supplies in different markets, as Unemployment rates in the United States. In economics, a person who is able and willing to work yet is unable to find a paying job is considered unemployed. The unemployment rate is the number of unemployed workers divided by the total civilian labor force, which includes both the unemployed and... unemployment in labor markets encourages excessive saving -- and vice-versa. Rather than prices adjusting to attain equilibrium, the main story is one of In economics, the concept of quantity adjustment refers to one possible result of supply and demand disequilibrium in a market, either due to or in the absence of external constraints on the market.

Active fiscal policy

As noted, the classicals wanted to balance the government budget, through slashing expenditures or (more rarely) raising taxes. To Keynes, this would exacerbate the underlying problem: following either policy would raise saving (broadly defined) and thus lower the demand for both products and labor. For example, Keynesians see Herbert Hoover Order: 31st President Term of Office: March 4, 1929 - March 4, 1933 Predecessor: Calvin Coolidge Successor: Franklin Delano Roosevelt Date of Birth Monday, August 10, 1874 Place of Birth: West Branch, Iowa Date of Death: Tuesday, October 20, 1964 Place of Death: New York City.

Thus, efforts to stimulate the economy would be self-defeating. Worse, it would be shifting resources away from productive use by the private sector to wasteful use by the government.

The Keynesian response is that such fiscal policy is only appropriate when unemployment is persistently high, above what is now termed the " The term NAIRU is an acronym for Non-Accelerating Inflation Rate of Unemployment.

Rather, it is the proposition that sometimes the economy needs active fiscal policy. Further, Keynesianism recommends counter-cyclical policies, for example raising taxes when there is abundant demand-side growth to cool the economy and to prevent inflation, even if there is a budget surplus. Classical economics, on the other hand, argues that one should cut taxes when there are budget surpluses, to return money to private hands. Because deficits grow during recessions, classicals call for cuts in outlays -- or, less likely, tax hikes. On the other hand, Keynesianism encourages increased deficits during downturns. In the Keynesian view, the classical policy exacerbates the An abstract business cycle The business cycle or economic cycle refers to the ups and downs seen somewhat simultaneously in most parts of an economy.

The " In economics, a multiplier effect occurs when a change in spending causes a disproportionate change in aggregate demand.

Two aspects of Keynes's model had implications for policy:

First, there is the "Keynesian multiplier", first developed by Richard F. Kahn in 1931. The effect on demand of any This article or section should include material from Exogenous factor Exogenous (or exogeneous) (from the Greek words exo and gen, meaning outside and production) refers to an action or object coming from outside a system. It is the opposite of endogenous, something generated from within the system. In an economic... exogenous increase in spending, such as an increase in government outlays is a multiple of that increase -- until potential is reached. Thus, a government could stimulate a great deal of new production with a modest outlay: if the government spends, the people who receive this money then spend most on consumption goods and save the rest. This extra spending allows businesses to hire more people and pay them, which in turn allows a further increase consumer spending. This process continues. At each step, the increase in spending is smaller than in the previous step, so that the multiplier process tapers off and allows the attainment of an equilibrium. This story is modified and moderated if we move beyond a "closed economy" and bring in the role of taxation: the rise in imports and tax payments at each step reduces the amount of induced consumer spending and the size of the multiplier effect.

Second, Keynes re-analyzed the effect of the interest rate on investment. In the classical model, the supply of funds (saving) determined the amount of fixed business investment. To Keynes, the amount of investment was determined independently by long-term profit expectations and, to a lesser extent, the interest rate. The latter opens the possibility of regulating the economy through Money supply (monetary aggregates, money stock), a macroeconomic concept, is the quantity of money available within the economy to purchase goods, services, and securities.

Great Depression, Keynes argued that this approach would be relatively ineffective compared to fiscal policy. But during more "normal" times, monetary expansion can stimulate the economy, mostly by encouraging construction of new housing.

Subsequent developments in Keynesian thought

After Keynes, Keynesian analysis was combined with classical economics to produce what is generally termed "the neoclassical synthesis" which dominates mainstream macroeconomic thought. Though it was widely held that there was no strong automatic tendency to full employment, many believed that if government policy were used to ensure it, the economy would behave as classical or neoclassical theory predicted.

Thus, the economist could use the IS-LM model to predict, for example, that an increase in the money supply would raise output and employment -- and then use the Phillips curve to predict an increase in inflation.

The strength of Keynesianism's influence can be seen by the wave of conservative economists which began in the late 1940s with Milton Friedman Milton Friedman (born July 31, 1912) is a U.S. economist, known primarily for his work on macroeconomics and for his advocacy of laissez-faire capitalism.

Instead of rejecting macro-measurements and macro-models of the economy, they embraced the techniques of treating the entire economy as having a supply and demand equilibrium.

Instead, the focus should be on monetary policy, which was largely ignored by early Keynesians.

It focuses on the supply and demand for money as the primary means by which economic activity is regulated. Monetary theory focuses on money supply and on inflation as an effect of the supply of... monetarism had both an ideological appeal -- since monetary policy does not, at least on the surface, imply as much government intervention the economy. The monetarist critique pushed Keynesians toward a more balanced view of monetary policy, and inspired a wave of revisions to Keynesian theory.

Through the 1950s, moderate degrees of government demand leading industrial development, and use of fiscal and monetary counter-cyclical policies continued, and reached a peak in the "go go" 1960s, where it seemed to many Keynesians that prosperity was now permanent. However, with the oil shock of 1973, and the economic problems of the Millennia: 1st millennium - 2nd millennium - 3rd millennium Centuries: 19th century - 20th century - 21st century Decades: 1940s 1950s 1960s - 1970s - 1980s 1990s 2000s Years: 1970 1971 1972 1973 1974 1975 1976 1977 1978 1979 Contents // 1 Events and trends 1.1 Technology 1.2 Science 1.3 War, peace and politics... 1970s, modern liberal economics began to fall out of favor. During this time, many economies experienced high and rising unemployment, coupled with high and rising inflation, contradicting the Phillips curve's prediction. This Stagflation is a term in macroeconomics used to describe a period of characteristic high inflation combined with economic stagnation, unemployment, or economic recession. Stagflation is thought to occur when there is an adverse shock (a sudden increase, say in the price of oil) in a countrys aggregate supply curve... stagflation meant that both expansionary (anti-recession) and contractionary (anti-inflation) policies had to be applied simultaneously, a clear impossibility.

This produced a "policy bind" and the collapse of the Keynesian consensus on the economy.

In the 1990s the "uncoupling" of money supply and inflation caused an increasing questioning of the original form of monetarism. The repeated failures of projections for economic recovery in Japan and the United States based on neo-classical synthesis models, as well as the failure of "big bang" marketization in the former Soviet Bloc, have encouraged the recent revival in Keynesian ideas, with particular emphasis on giving the Keynesian macroeconomic analysis theoretically sound foundations in microeconomics. These theories have been called New Keynesian economics developed partly in response to new classical economics. It strives to provide microeconomic foundations to Keynesian economics by showing how imperfect markets can justify demand management by the government or its central bank. The main assumption of New Keynesian economics that distinguishes it from the new classical... new Keynesian economics.

Price stickiness means that there are a variety of possible equilibria in the short run, so that rational expectations models do not produce any simple result.

While the Keynesian triumphalism of the 1960s is certainly not due for a revival, Keynesian ideas persist, often used to attain very conservative goals. Many observers find it hard to distinguish the new Keynesianism from old monetarism, except that the latter's emphasis on the money supply has been dropped or downgraded.
