Criticisms. Keynes refuted Say’s Law of markets that supply always … Criticisms of Keynes's ideas had begun to gain significant acceptance by the early 1970s, as they were then able to make a credible case that Keynesian models no longer reflected economic reality. The equilibrium of the money market explains the price level corresponding to the full employment level of output which relates Panel (E) and Panel (B) with MQ line. 1936. The law of diminishing returns operates in production. Criticism of Keynesian Theory. Then the real wage corresponding with the money wage is determined by the (W/P) curve, as shown in Panel (D). When money wages fall, real wages rise and vice versa. According to Pigou, the tendency of the economic system is to automatically provide full employment in the labour market when the demand and supply of labour are equal. This is just the reverse of Say’ law of markets which states that supply creates its own demand. Keynesian economics is a theory that says the government should increase demand to boost growth. But as a remedial measure, Keynes did not suggest a complete reconstruction of the capitalist society on socialistic pattern. The state may directly invest to raise the level of economic activity or to supplement private investment. Keynes theory does provide solution of all types of... 2. to be constant during the short period and so neglects long-run influences on demand. It may pass legislation recognising trade unions, fixing minimum wages and providing relief to workers through social security measures. The theory is ascribed to early Classical economists like Adam Smith, Ricardo, and Malthus and neo-classical like Marshall, Pigou and Robbins. The following are the main features of the Keynesian theory of employment which determine its basic nature: (i) It is general theory in the sense that- (a) it deals with all levels of employment, whether it is full employment, widespread unemployment or some intermediate level; (b) it explains inflation as readily as it does unemployment, because basically both situations are a matter of volume of employment, and (c) it relates to changes in the employment and output in the economic system as a whole. The labor has money illusion. The central problem of the General Theory is- What determines the level of employment? Vie General Theory of Employment, Interest and Money. Keynesian demand management has been at the centre of some of the worst economic outcomes in history, from the great stagflation of the 1970s to the lost decade and more in Japan following the expenditure program of the 1990s. • Keynes: General Theory of Employment, Interest and Money • Kalecki: Theory of Economic Dynamics • Robinson: Accumulation of Capital • Minsky: Stabilizing an Unstable Economy • Lavoie: Introduction to Post Keynesian Economics • Hein & Stockhammer: New Guide to Keynesian Macroeconomics and Economic Policies They believe Criticism on Keynesian Theory: From mid 1970 onward, the Keynesian theory of employment came under sharp criticism from the monetarists. Keynes not only criticized classical economists, but also advocated his own theory of employment. Keynes’ theory of employment is called the effective demand theory of employment. He in his book, 'General Theory', has severally criticized the Say's Law on the following grounds: (i) Possibility of deficiency of effective demand. Since MPN declines as employment increases, it follows that the level of employment increases as the real wage (W/P) declines. Effective demand manifests itself in spending of income or the flow of total expenditure in the economy. (vi) The government is assumed to have no part play either as taxer or a spender, i.e., the fiscal operations of the government is not explicitly recognised. In other words, total output (Q) is a function (f) of capital stock (K), technical knowledge T, and number of workers (TV). In modern times, workers have formed strong trade unions which resist a cut in money wage. John Maynard Keynes in his General Theory of Employment, Interest and Money published in 1936, made a frontal attack on the classical postulates. The interest rate will rise, saving will increase and investment will decline. Keynes's income‐expenditure model. He wrote several books. The classical economists believed that money was demanded for transactions and precautionary purposes. Keynes rejected the fundamental classical assumption of full employment equilibrium in...

This process will go on till receipts become equal to costs. 2. As production increases, the demand for labour also increases. There is hardly any nation, planned or unplanned, which has not accepted full employment as the ultimate goal of its economic policy. According to Keynes, the productive capacity of the economy sometimes behaves erratically, affecting production, employment, and inflation. This is explained by the Quantity Theory of Money which states that the quantity of money is a function of the price level, P=f (MV). (i) Keynesian theory is not a complete theory of employment in the sense that it does not provide a comprehensive treatment of unemployment, (a) It deals only with cyclical unemployment and ignores other forms of unemployment, such as, frictional unemployment, technological unemployment, etc. The classical theory of employment is criticized on the following grounds: (1) Equilibrium Level need not be Full Employment Level. Keynes refuted the Pigovian formulation that a cut in money wage could achieve full employment in the economy. This explains why the marginal efficiency of capital and hence investment expenditure fluctuates. This will induce entrepreneurs to increase employment. The flow of expenditure also represents the value of total output because total price of national output is just the same thing as the total expenditure made and the total income received by the community. The supply of labour will fall and the demand for labour will rise and the equilibrium point E will be restored along with the full employment level Nr On the contrary, if the wage rate falls from W/P0 to WP2 the demand for labour (W/P2-d1) will be more than its supply (W/P2-s1). Each market involves a built-in equilibrium mechanism to ensure full employment in the economy. This is shown in the form of the following production function: Q=f (K, T, N), where total output (Q) is a function (f) of capital stock (K), technical knowledge (T), and the number of workers (N). This is also the point of effective demand. The British economist John Maynard Keynes, who write the book of General Theory of Employment, Interest and Money was the foundation of the Keynesian system, was more heavily influenced by events in his own country than those in the United States. (London: Macmillan. The 45° line shows Y = C + I. Increased sales will necessitate the employment of more labour and ultimately full employment will be attained. Thus Keynes integrated monetary and real sectors of the economy. According to him, there is an inverse relation between the two. In addition in Keynes theory the Investment is volatile and its level depends on future expectations of businesses to … Presence of closed economy ignores the effect of foreign trade.

(ii) There exists no direct and determinable relationship between effective demand and volume of employment.

Criticisms of Keynes’s Liquidity Theory of Interest: The Keynesian theory of interest has been severely criticised by Hansen, Robertson, Knight, Hazlitt, Hutt and others. He integrated monetary theory with value theory, and brought the theory of interest in the domain of monetary theory by regarding the interest rate as a monetary phenomenon.
