Keynes's assumption about wage behaviour has been the subject of much criticism. According to the classical theory of income and employment. The theories of employment are broadly classified into two: (a) Classical theory of employment (b) Keynesian theory of employment. According to this theory, in an economy income and employment are in equilibrium at the level at which Aggregate Demand (AD) = Aggregate Supply (AS). Income fluctuates cyclically in Keynes's theory, with the effect being borne by prices if income increases during a period of full employment, and by employment in other circumstances. Building on his theory, Keynesians have stressed the relationship between income, output, and expenditure. Keynesian Theory of Income Determination . Thus investment decisions are governed by whether the expected rate of return on the machine is greater than the cost of borrowing the necessary funds, or, if the funds are already available, the cost of the earnings lost by purchasing the machine rather than by lending out of funds.

It needs to be noted that Keynesian theory is supposed to apply under short run and perfect competition. Even, in Keynesian theory, there lies the assumption of the constant level of income in the disguised form. But, there is no guarantee that the saved part of income will be spent on investment goods. The Neo-Keynesian theory was articulated and developed mainly in the U.S. during the post-war period. The Keynesian theory of the determination of equilibrium output and prices makes use of both the income‐expenditure model and the aggregate demand‐aggregate supply model, as shown in Figure . They regarded unemployment as a temporary phenomenon and assumed that there is always a tendency towards full employment. In other words, Keynes paid emphasis on the aggregate demand function.

John Maynard Keynes offered new thinking on income and employment theory with the publication of General Theory of Employment, Interest and Money (1936). In 1936, he published his epoch-making book General Theory of Employment, Interest and Money and set out his new theory in it. The theory is ascribed to early Classical economists like Adam Smith, Ricardo, and Malthus and neo-classical like Marshall, Pigou and Robbins.

Given these assumptions, the Keynesian chain of causation between changes in the quantity of money and in prices is an indirect one through the rate of interest. If the desire to save from their particular income is more than the desire for substitution expenditure has become a reverse relationship, demand, and employment increase i.e., when the desire to save, among people is lesser than the substitution expenditure in the society, demand, and employment increases. The second key Keynesian assumption is the notion of effective demand, that consumption expenditures are based on the disposable income actually available to the household sector rather than income that would be available at full employment. Therefore, he made the specific assumption of short-period so as to concentrate on the problem at hand. He wrote several books. Keynes is considered to be the greatest economist of the 20 th century. The two broad features of classical theory of employment were: (a) The assumption of full employment of labour and other productive resources, and (b) The flexibility of prices and wages to bring about the full employment (a) Full employment:- According to classical economists, the labour and the other resources are always fully employed. Assumptions of Full Employment 4. Since unemployment results from the deficiency of aggregate demand, employment and income can be increased by increasing aggregate demand. The two wide features of classical theory of employment were: (a) The assumption of full job of labour and other fruitful resources, and (b) The flexibility of prices and wages to bring about the full employment (a) Full career: – According to classical economists, the labour and the other solutions are always totally employed. Keynes in his famous book, 'General theory', has used two methods for the determination of national income at a particular time: (1) Saving Investment Method. Keynes described his premise in “The General Theory of Employment, Interest, and Money.” Published in February 1936, it was revolutionary. The two extensive features of traditional theory of employment were: (a) The assumption of full career of labour and other successful resources, and (b) The flexibleness of prices and wages to get about the total employment (a) Full job: – In respect to traditional economists, the labour plus the other resources are always completely employed. A market economy contains sufficient built in mechanisms to cause the economy level of income to move automatically to a position at which there is full employment. A complete theory should explain how to get both full and fair employment. The central problem in macro … Wage behaviour and the Phillips curve. (2) Aggregate Demand and Aggregate Supply Method. John Maynard Keynes. He depends heavily on an assumption of perfect competition, which indeed is implicit in the The classical and the neoclassical economists almost neglected the problem of unemployment. According to Keynes, a part of the increased income is spent on consumer goods and the other saved. Since during short period supply is constant, it is because of deficiency in effective demand, which causes unemployment. KEYNESIAN THEORY OF EMPLOYMENT J.M.

Keynesian economics is called the Keynesian revolution. Keynes did not attempt to solve frictional, technological unemployment and chronic unemployment of under-developed countries. Actual equilibrium, ONe, is short of fill employment equilibrium, ONe. ) Robert Waldmann. In economics, the Laffer curve, popularized by supply-side economist Arthur Laffer, illustrates a theoretical relationship between rates of taxation and the resulting levels of the government's tax revenue.The Laffer curve assumes that no tax revenue is raised at the extreme tax rates of 0% and 100%, and that there is a tax rate between 0% and 100% that maximizes government tax revenue. Keynes theory does provide solution of all types of unemployment. Keynesian economics is a macroeconomic economic theory of total spending in the economy and its effects on output, employment, and inflation. Prior to it, economists confined their attention to what we now call ‘price theory’ and did not analyse the economy as a whole. The Keynesian theory of employment and income is also explained in terms of the equality of aggregate supply (C+S) and aggregate demand (C+I).
