He saw the economy as unable to maintain itself at full employment automatically, and believed that it was necessary for the government to step in and put purchasing power into the hands of the working population through government spending. His whole theory is centered around boosting aggregate demand so that capitalists will maximize investment. Cross-examining Sir Richard Hopkins, a Second Secretary in the Treasury, before the Macmillan Committee on Finance and Industry in 1930 he referred to the "first proposition" that "schemes of capital development are of no use for reducing unemployment" and asked whether "it would be a misunderstanding of the Treasury view to say that they hold to the first proposition". In particular, fiscal policy actions (taken by the government) and monetary policy actions (taken by the central bank), can help stabilize economic output over the business cycle. According to the theory, government spending can be used to increase aggregate demand, thus increasing economic activity, reducing unemployment and deflation. If we follow Keynes's initial account under which liquidity preference depends only on the interest rate r, then the LM curve is horizontal. Paul Krugman wrote "I don’t think we need to take that as an immutable fact of life; but still, what are the alternatives? The classical tradition of partial equilibrium theory had been to split the economy into separate markets, each of whose equilibrium conditions could be stated as a single equation determining a single variable.  New classical theorists demanded that macroeconomics be grounded on the same foundations as microeconomic theory, profit-maximizing firms and rational, utility-maximizing consumers. Kahn's multiplier gives the title ("The multiplier model") to the account of Keynesian theory in Samuelson's Economics and is almost as prominent in Alvin Hansen's Guide to Keynes and in Joan Robinson's Introduction to the Theory of Employment. , The paradox of thrift was stated in 1892 by John M. Robertson in his The Fallacy of Saving, in earlier forms by mercantilist economists since the 16th century, and similar sentiments date to antiquity. A good capitalist wants to own all of the means of production so they can maximize profits. Less classically he extends this generalization to the schedule of the marginal efficiency of capital. - Back to Basics - Finance & Development, September 2014", "Convergence in Macroeconomics: Elements of the New Synthesis", "Current Global Imbalances and the Keynes Plan", "601 David Singh Grewal, What Keynes warned about globalization", "Nixon's Economic Policies Return to Haunt the G.O.P.  In 1933 he gave wider publicity to his support for Kahn's multiplier in a series of articles titled "The road to prosperity" in The Times newspaper. Many honest conservatives like Peter Drucker and Bruce Bartlett have pronounced Keynes to be a conservative and even a neoconservative. Keynesians emphasized the dependence of consumption on disposable income and, also, of investment on current profits and current cash flow. Interpreting Keynes's work is a contentious topic, and several schools of economic thought claim his legacy. Nor were his practical recommendations very different: "on many occasions in the thirties" Pigou "gave public support ... to State action designed to stimulate employment. The value Keynes assigns to his multiplier is the reciprocal of the marginal propensity to save: k = 1 / S '(Y ). For example, if a government ran a deficit of 10% both last year and this year, this would represent neutral fiscal policy. These models have been developed into the real business-cycle theory, which argues that business cycle fluctuations can to a large extent be accounted for by real (in contrast to nominal) shocks. , James M. Buchanan criticized Keynesian economics on the grounds that governments would in practice be unlikely to implement theoretically optimal policies. In a capitalist system, people earn money from their work. This post-war domination by neo-Keynesian economics was broken during the stagflation of the 1970s. The IS-LM model uses two equations to express Keynes' model. The designation of the initial spending as "investment" and the employment-creating respending as "consumption" echoes Kahn faithfully, though he gives no reason why initial consumption or subsequent investment respending shouldn't have exactly the same effects. " Keynes considers his second objection the more fundamental, but most commentators concentrate on his first one: it has been argued that the quantity theory of money protects the classical school from the conclusion Keynes expected from it.. The existence of net hoarding, or of a demand to hoard, is not admitted by the simplified liquidity preference model of the General Theory. We may construct a graph on (Y, r ) coordinates and draw a line connecting those points satisfying the equation: this is the IS curve. But only Marxism offers a solution. Macroeconomics is the study of the factors applying to an economy as a whole. Keynes was the real father of neoconservatism, far more than [economist F.A.] It was written during the Great Depression, when unemployment rose to 25% in the United States and as high as 33% in some countries. At the time that Keynes's wrote the General Theory, it had been a tenet of mainstream economic thought that the economy would automatically revert to a state of general equilibrium: it had been assumed that, because the needs of consumers are always greater than the capacity of the producers to satisfy those needs, everything that is produced would eventually be consumed once the appropriate price was found for it. John M. Keynes (Source: Biography Online) Second, he thought Keynes's economic theories appealed to a group far broader than economists primarily because of their link to his political approach. But Keynesian economics persists today, partly because it satisfies unwarranted suspicions that capitalism is inherently unstable or unsustainable, and partly because it rationalizes government policy intervention and activism. Keynes's ideas influenced Franklin D. Roosevelt's view that insufficient buying-power caused the Depression. The whole basis of the General Theory was around entrepreneurs and investment: “The outline of our theory can be expressed as follows. Prior to Keynes, a situation in which aggregate demand for goods and services did not meet supply was referred to by classical economists as a general glut, although there was disagreement among them as to whether a general glut was possible. He was the leader of the British delegation to the United Nations Monetary and Financial Conference in 1944 that established the Bretton Woods system of international currency management. The term "liquidity trap" was coined by Dennis Robertson in his comments on the General Theory, but it was John Hicks in "Mr. Keynes and the Classics" who recognised the significance of a slightly different concept. The Keynesian utopia will have the good parts of capitalism — the “efficiency of the decentralization of decisions and of individual responsibility” — without the bad, “its failure to provide for full employment and its arbitrary and inequitable distribution of wealth and incomes.” The Liberal Party fought the 1929 General Election on a promise to "reduce levels of unemployment to normal within one year by utilising the stagnant labour force in vast schemes of national development". That Keynesianism is a political philosophy that is relatively unconcerned with capitalism for capitalism’s sake as much of bourgeois economics is. , A. C. Pigou was at the time the sole economics professor at Cambridge. In the postwar era, Keynesian analysis was combined with neoclassical economics to produce what is generally termed the "neoclassical synthesis", yielding neo-Keynesian economics, which dominated mainstream macroeconomic thought. Paul Krugman has worked extensively on the liquidity trap, claiming that it was the problem confronting the Japanese economy around the turn of the millennium. Keynesian Economics is an economic theory of total spending in the economy and its effects on output and inflation developed by John Maynard Keynes. This argument rests upon the assumption that if a surplus of goods or services exists, they would naturally drop in price to the point where they would be consumed. " Two months later Keynes, then nearing completion of his Treatise on money, and Hubert Henderson collaborated on a political pamphlet seeking to "provide academically respectable economic arguments" for Lloyd George's policies. In the article Kalecki predicted that the full employment delivered by Keynesian policy would eventually lead to a more assertive working class and weakening of the social position of business leaders, causing the elite to use their political power to force the displacement of the Keynesian policy even though profits would be higher than under a laissez faire system: The erosion of social prestige and political power would be unacceptable to the elites despite higher profits. Aggregate demand must equal total income, so equilibrium income must be determined by the point where the aggregate demand curve crosses the 45° line.  Keynesian economics was later redeveloped as New Keynesian economics, becoming part of the contemporary new neoclassical synthesis. As an example, he suggests that the money may be raised by borrowing from banks, since ... ... it is always within the power of the banking system to advance to the Government the cost of the roads without in any way affecting the flow of investment along the normal channels. As Drucker noted: “[Keynes] had two basic motivations…one was to destroy the labor unions and the other was to maintain the free market. In the early era of social liberalism and social democracy, most western capitalist countries enjoyed low, stable unemployment and modest inflation, an era called the Golden Age of Capitalism. For example, during economic … Nations with a surplus would have a powerful incentive to get rid of it, which would automatically clear other nations' deficits. His whole idea was to have an impotent government that would do nothing but, through tax and spending policies, maintain the equilibrium of the free market. The second is that classical theory assumes that, "The real wages of labour depend on the wage bargains which labour makes with the entrepreneurs," whereas, "If money wages change, one would have expected the classical school to argue that prices would change in almost the same proportion, leaving the real wage and the level of unemployment practically the same as before. I am politically centrist and I am not sure I’d call myself a “Keynesian”, but I appreciate the nuances in his work and I think his view of the world was balanced in a manner that made a good deal of sense.

For another, Keynesian economics is a theory of the capitalist system. 5. His whole theory is centered around boosting aggregate demand so that capitalists will maximize investment. But just as pre-Keynesian classical economics was unsustainable in the 1920s and 30s and offered no solutions to the problems of the Great Depression or reconstruction after 1945, so modern neoliberalism has both contributed to the problems which beset modern capitalism and offers no guidance about what to do to resolve those problems. He thought that if it is generally accepted that democratic politics is nothing more than a battleground for competing interest groups, then reality will come to resemble the model. Keynes argued that the solution to the Great Depression was to stimulate the country ("incentive to invest") through some combination of two approaches: If the interest rate at which businesses and consumers can borrow decreases, investments that were previously uneconomic become profitable, and large consumer sales normally financed through debt (such as houses, automobiles, and, historically, even appliances like refrigerators) become more affordable. In sharp contrast to the traditional interpretation, Rod O’Donnell argues Keynes was a socialist. The crux of Keynesian economics is to maximize business investment so that capitalists will hire workers which will increase output. Thus, to justify any given amount of employment there must be an amount of current investment sufficient to absorb the excess of total output over what the community chooses to consume when employment is at the given level. An intellectual precursor of Keynesian economics was underconsumption theories associated with John Law, Thomas Malthus, the Birmingham School of Thomas Attwood, and the American economists William Trufant Foster and Waddill Catchings, who were influential in the 1920s and 1930s. If the economy is in a position such that the liquidity preference curve is almost vertical, as must happen as the lower limit on r is approached, then a change in the money supply M̂ makes almost no difference to the equilibrium rate of interest r̂ or, unless there is compensating steepness in the other curves, to the resulting income Ŷ. Keynes argued that inadequate overall demand could lead to prolonged periods of high unemployment. The theoretical apparatus of supply and demand curves developed by Fleeming Jenkin and Alfred Marshall provided a unified mathematical basis for this approach, which the Lausanne School generalized to general equilibrium theory. For it will be demonstrated later on that, pari passu with the building of roads, funds are released from various sources at precisely the rate that is required to pay the cost of the roads. The psychology of the community is such that when aggregate real income is increased aggregate consumption is increased, but not by so much as income. Not only do the authors of the "new economics" largely ignore the evils which some of us believe flow from government intervention; not only do they attribute the imperfections of the mixed economy to capitalism rather than to governmentalism; but one looks in vain for any principle by which to distinguish between individual right and government authority. The book was published in 1936. For example, both Presidents Ronald Reagan (1981-89) and George W. Bush (2001-09) supported policies that were, in fact, Keynesian, even though both men were conservative leaders. Others recognize that Keynesian policies leave capitalism intact, but see such policies as a means of gradually achieving socialism through peaceful means.  An example of a counter-cyclical policy is raising taxes to cool the economy and to prevent inflation when there is abundant demand-side growth, and engaging in deficit spending on labour-intensive infrastructure projects to stimulate employment and stabilize wages during economic downturns. As the 1929 election approached "Keynes was becoming a strong public advocate of capital development" as a public measure to alleviate unemployment.  The horizontal axis denotes total income and the purple curve shows C (Y ), the propensity to consume, whose complement S (Y ) is the propensity to save: the sum of these two functions is equal to total income, which is shown by the broken line at 45°. This laissez-fair, or hands off, approach had endeavored to … Saving is that part of income not devoted to consumption, and consumption is that part of expenditure not allocated to investment, i.e., to durable goods. Keynes, also called "1st Baron Keynes," was a British Economist who lived from 1883 to 1946. He mentions "increased public works" as an example of something that brings employment through the multiplier, but this is before he develops the relevant theory, and he does not follow up when he gets to the theory. Keynesian ideas became almost official in social-democratic Europe after the war and in the U.S. in the 1960s.  He also argued that empirical evidence makes it pretty clear that Buchanan was wrong. John Maynard Keynes is widely regarded as one of the twentieth century’s outstanding liberals. Hopkins responded that "The first proposition goes much too far. Investment and consumption by government raises demand for businesses' products and for employment, reversing the effects of the aforementioned imbalance. The Keynesian model adopted in the U.S., combined with the production boom created by World War II, fostered a period of economic growth and accumulation for U.S. corporations that set the U.S. on course to be the global economic power during this epoch of capitalism.  This became the mechanism of the "ratio" published by Richard Kahn in his 1931 paper "The relation of home investment to unemployment", described by Alvin Hansen as "one of the great landmarks of economic analysis". First, he thought whatever the economic analysis, benevolent dictatorship is likely sooner or later to lead to a totalitarian society. Start studying Keynesian vs. Laissez-faire Economics. This perception is reflected in Say's law and in the writing of David Ricardo, which states that individuals produce so that they can either consume what they have manufactured or sell their output so that they can buy someone else's output. Keynes sought to supplant all three aspects of the classical theory. Keynes viewed the money supply as one of the main determinants of the state of the real economy. Keynes's ideas became widely accepted after World War II, and until the early 1970s, Keynesian economics provided the main inspiration for economic policy makers in Western industrialized countries. Attempts by the Bank of Japan to increase the money supply simply added to already ample bank reserves and public holdings of cash.... The liquidity trap is a phenomenon that may impede the effectiveness of monetary policies in reducing unemployment. Some, like Bernie Sanders, see Keynesian policies as examples of “democratic socialism” pointing to Scandinavian welfare states which have also been eroded by neoliberalism.
