In the classical model the components of aggregate demand consumption and investment determine equilibrium interest rate. The Classical Vs.Keynesian Models of Income and Employment! It is the exogenous variable (determined outside the model) which leads to changes in output and employment. In the classical system, full employment is achieved automatically due to wage-price flex­ibility. So we can say that the total demand for money in an economy is a func­tion of money national income or output. Our mission is to provide an online platform to help students to discuss anything and everything about Economics. The aggregate production function is: Y = f (K , L) … (3.2). Share Your PPT File, Keynesian Theory of In­voluntary Unemployment (With Diagram). Supply of labour is positively related to the real wages (W/P). 2. The classical economists advocated that the government should follow the laissez-faire approach of economy. For this, they have to determine the level of output to be produced and the number of workers to be employed. Classical economists such as, J.S. Saving curve (S) and investment curve (I) are equal to each other at point E where the equilibrium volume of saving (SE) is equal to the equilibrium value of investment (IE). CHAPTER 5: OUTPUT-EMPLOYMENT THEORIES (CLASSICAL AND KEYNESIAN) 5.1 Classical Theory (A) Introduction: Employment and output analysis at macro level has become an important part of economic theory only during and after the Second World War period. Say’s Law. But, in the short ran, the stock of fixed capital and wage goods inventories are given and constant. This framework is composed of an aggregate production function, the labour market, the money market, and the goods market. Due to decrease in the profit level, firm will demand less labour. The aggregate demand curve for labour is the horizontal summation of all individual firm’s demand curve for labour. Inciden­tally, this is the full employment position, de­noted by LE = LF. The goods market is concerned with the way the fixed output or income is split between saving and consumption. The complete classical model of income and employment determination in an economy in Fig. TWO THEORIES OF EMPLOYMENT 46 1.1 General Theory or Special Case? The intersec­tion between DL and SL curves at point E in the upper part of the figure determines the equilibrium level of employment (LF) at the equilibrium real wage rate (W/P)F. The equilibrium of the classical labour market is one where everyone willing to work at the real wage (W/P)F is able to find work. Equation 3.10 states that people hold cash balance since there is a gap between money receipts and expenditures. In order to maximize their profit, firms employ factors of production to the point where margi… One important conclusion from the classical model is the classical dichotomy. Theory of emplyment 1. Criticism of Classical Theory: Several economists have criticized the classical theory of employment. The factors which are operating on the supply side determines the level of output and employment. 46 1. More labour is demanded at a lower wage. In the Keynesian theory, employment depends upon effective demand. CRITICISM OF KEYNESIAN THEORY 3. I. Criticisms. ADVERTISEMENTS: The Keynesian Theory of Income, Output and Employment!

Interest rate that guarantees that changes in the particular components of demands do not affect the aggregate level of commodity demand. One essential feature that follows from the classical money market is that money is neutral. Mill, Marshall, Pigou etc. The description of the various equations in the model is as follows: 1. In this economy there cannot be over production … Equilibrium real wage rate and the equi­librium level of employment are determined at that point where the negative sloping la­bour demand curve cuts the positive sloping labour supply curve. People save in the current period to have larger income or consumption at a future date. What is required for stable price level is the stable money supply since quantity of money determines the price level. (SE > IE). 1. MC of labour is equal to the money wage divided by the marginal product of labour, MPL, i.e.. where W is the money wage, P is the absolute price level, and W/P is the real wage. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. Investment refers to the creation of additional stock of capital. Say’s Law in a Barter Economy. Classical Theory of Output. Their conviction in wage flexibility. Theory of Income and Output 8. where K denotes a constant capital stock and L denotes quantities of variable input, labour. Demand for labour is negatively related to the real wages (W/P). Thus, in the classical model the factors that determine the output and employment are the factors which determine the positions of: Welcome to EconomicsDiscussion.net! As we add more labour, output increases but at a decreasing rate (i.e., increment to the output decreases) MPN decreases but is positive. 2. Classicists answered this question in terms of the quantity theory of money which deter­mines aggregate demand, which, in turn, de­termines the price level. The corresponding equilib­rium level of output (at the equilibrium level of employment) is YF. TOS4. Introduction to Macro Economics, its importance and scope. It shows at very low level of output as we employ more labour to the given capital, productivity of the last worker added does not fall. Classical Theory Of Income And Employment (HINDI) - Duration: 32:34. Fig. In the lower panel, aggregate produc­tion function has been shown. 3.7. At low level of Labour input before N1. Thus, investment, in the classical system, depends on the market rate of interest. ADVERTISEMENTS: To build up a classical macroeconomic model, here we will consider a particular framework within which the classical system can be studied. The classical theory relates only to the special case of full employment. 3. Say's Law of Market. The factors which are operating on the supply side determines the level of output and employment. Output creates income. Assumptions 4. The classical theory of income, output and employment is based on the following assumptions: 1. Theories of Income, Output and Employment Determination: Classical and Keynesian; Principle of effective demand. The vector (OL), the slope of which is (1/k), shows the levels of PY that can be supported by different quantities of money supply. Thus, demand for labour depends inversely on real wage. Classical economists such as Adam Smith and Ricardo maintained that the growth of income and employment depends on the growth of the stock of fixed capital and inventories of wage goods. In the classical model, equilibrium level of output is determined by the employment of labour. determine output, employment and real wage in the classical system. J. M. Keynesian theory is a general theory. 1. 2. Thus, it is the supply of labour which plays an important role in the determination of labour market equilibrium and thus the employment and output level. Classical Theory of Employment: Definition and Explanation: Classic economics covers a century and a half of economic teaching. Keynesian Theory of Income and Employment: Definition and Explanation: John Maynard Keynes was the main critic of the classical macro economics. The Classical model of employment consists of 2 components: Production function shows the relationship between input and output. The scope of this chapter is limited to Keynesian Theory. The Production function is a straight line which exhibits constant returns to scale. CLASSICAL THEORY II. Share Your PDF File Content Guidelines 2. Thus, full employment is regarded as a normal situation and any deviation from this level is something abnormal since competition automatically pushes the economy toward full employment. But money supply does not have any impact on Y which is determined in the real sector and Y is fixed due to full employment. 1 Equilibrium level of income and employment is established at a point where AD = AS. The Classical economists disagreed with the Mercantilist view who emphasized State interference and money factors, for the determination of real variables like output and employment. All In All 3,244 views. Variables 5. 1. The Amount of Labour employed will be determined at the point where: Aggregate Demand for Labour (Nd) = Aggregate Supply of Labour (Ns). Firms: Firms are engaged in actual production. Share Your PDF File The policy implication of this classical model is that monetary policy alone can influence economic activity. Interest Rate Determination: Goods Market. have supported this law of J.B. Say. However in this essay we will see it from another perspective: This means that changes in money stock affect only absolute prices and money wages proportionately. Say formulated a law which is known as the “Say's Law of Market”. With the help of these two functions output and employment is determined. This is the gist of Keynesian or Macro approach. This equilibrium out­put level is also called full employment out­put level. Summary 6. Employment-Output Determination: Labour Market: 2. Therefore, Equilibrium level of employment → N*, as here Nd = Ns shown by point ‘e’, Equilibrium level of output →Y* (Fig. Thus, the supply curve of labour is positively sloped. This is because wages are the income of the labourer. Money wage is adjusted automatically by the market. In the State of Equilibrium.
