Now the pertinent question is what is the guarantee that investment expenditure will be equal to savings of the households. Classical economists believed in the Quantity Theory of Money according to which it is the supply of money that determines price level in an economy. The classical theory of employment states that in a labor market, employment for labors is determined by the interaction between demand and supply of labor, where the workers provide a constant supply of labor, while the employer makes demand for them. It will be seen from the lower panel of Fig. This is income effect of the rise in real wage rate which tends to increase leisure and reduce labour-hours supplied. 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. Thus, the demand curve for labour is derived from the marginal product curve of labour. The pertinent questions is how with changes in price level, which in the classical theory depends on the quantity of money, leave level of employment and output unaffected. For instance, if money supply in an economy equals Rs. Further, according to them, rate of interest is determined by supply of savings and demand for investment. Saving represents a withdrawal of some income from the expenditure flow. The Classical Theory of Employment and Output! Aggregate demand being equal to aggregate supply, there is no problem of deficiency of demand. Supply of labour, as seen above, is determined by individual prefer­ences between work and leisure and demand curve for labour is determined by marginal product of labour. With velocity of money V, aggregate expenditure on final goods and services will be equal to M1V and corresponding to this aggregate demand curve AD1 has been drawn in Fig. The classical theory assumes over the long period the existence of full employment without inflation. 2. Thus, the problem of deficiency of aggregate demand would not be faced and full employment of labour will prevail. This is illustrated in Fig. Thus whatever the price level, money wage rate changes in such a way that equilibrium real wage rate, level of employ­ment and therefore output remain constant. The classical economists believed that: (i) An economy as a whole always functions at the level of full employment of resources. It therefore follows that increase in the quantity of money causes price level to rise. unemployment of workers) will cause real wage rate to fall to W1/P0 (where W1 < W0) at which new equilibrium between demand for and supply of labour is again established at point E1. 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 aggregate supply curve is shown in Fig. This disequi­librium between labour demand and supply will cause money wage rate to rise to the level so that original real wage rate determined by labour market equilibrium is restored. As employment increases, output … 3.1 that supply and demand for labour are in equilibrium at the real wage rate (W/P). Thus, with rise in price level, level of employment remains unchanged and, given the aggregate production function, level of output will remain con­stant. In fact, the former coincides with the latter. Let us first explain how in classical theory price level in the economy is determined. On the other hand, the supply of labour by the households in the economy depends on their pattern of preference between income and leisure. He in his book 'General Theory of Employment, Interest and Money' out-rightly rejected the Say's Law of Market that supply creates its own demand. 3.3 (a). Factors of production earn their incomes during the process of production. 3.5. Thus in classical model aggregate supply curve reflects supply-determined nature of output and does not depend on the aggregate demand and price level. At a higher rate of interest i2, the investment demand is less than the intended supply of savings. Determination of income and employment in an economy with saving and investment; and. When real wage rate rises leisure becomes relatively more expensive, that is, opportunity cost or price of leisure in terms of income forgone by not working goes up. Now, due to the excess demand for investment in the loan market rate of interest would go up. Take your favorite fandoms with you and never miss a beat. Although it is correct that produc­tion of output generates an equal amount of income but what is the guarantee that all income earned by factors/households will be actually spent on goods and services produced. Thus, it is at rate of interest I that loan market is in equilibrium, i.e., investment is equal to savings (I = S). 2005: Edward Elgar Publishing; https://economics.fandom.com/wiki/Classical_Theory_of_Employment_and_Output_Determination?oldid=4070. Further, it is the wage flexibility (i.e., changes in the wage rate) which ultimately brings about this full-employment situation. The classical economists believed that substitution effect is larger than income effect of the rise in real wage rate and as a result supply of labour increases with the rise in wage rate. We will adopt that approach here. That is, economic forces would always be generated so as to ensure that the demand for labour was always equal to its supply. In fact, a part of income might be saved. From equation (ii) above it follows that, with V and Q remain­ing constant, increase in money supply will cause proportionate increase in the price level. On the contrary, if somehow real wage rate in the labour market is (W/P)2 the firms would demand more labour than is offered at this real wage rate. 3.2 that, given the stock of fixed capital and the state of technology, employment of ONF labour produces OYF output. 3.1(A) where following the =c decrease in aggregate demand for output labour demand curve shifts to the left to Nd1 so that at the initial wage rate W0 / P0 fewer workers will be demanded than the number of workers who are willing to supply their labour at this wage rate. The Classical Theory Of Employment amd output The fundamental principle of the classical theory is that the economy is self-regulating. 500 crores and velocity of circulation is 4, then 500 X 4 = 2000 crores will be aggregate expenditure. Further, due to operation of Say’s law and wage-price flexibility full employment of resources occur in the economy. Summary of Keynesian Theory of Employment: Keynesian theory of employment, as developed in the General Theory is outlined in Chart-1. It follows from above that the quick changes in the real wage rate upward or downward ensures that neither excess supply of labour, nor excess demand for labour will persist and thus equilibrium will be reached with full employment of labour in the economy. Classical economists maintain that the economy is always capable of achieving the natural level of real GDP or output, which is the level of real GDP that is obtained when the economy's resources are fully employed. They showed that Say’s law that supply creates its own demand holds good even in the presence of saving. The short- run classical theory of income and employment can be explained through the following three stages: 1. Keynes used his income‐expenditure model to argue that the economy's equilibrium level of output or real … Value of output produced will therefore be equal to the income generated in the process of production. TOS 7. Classical view that forces or mechanisms exist to restore a position of full employment. Income and employment theory, a body of economic analysis concerned with the relative levels of output, employment, and prices in an economy. Friedman, Milton. This is be­cause at a lower price level, given the aggre­gate expenditure as determined by MV, more quantity of goods and services will be purchased. The determination of output and employment in the classical theory occurs in labour, goods and money markets in the economy. Under-employment equilibrium. Now, if price level is doubled to 2P1 and money wage rate rises to 2 W1, then the equilibrium real wage rate will become equal to 2W1/2P1 = W1/P1. Snowdon, Brian and Howard R. Vane. Classical … Now, an important question is why in classical model, aggregate supply curve is perfectly inelastic. S = S (i) – Saving Function . For this, they have to determine the level of output to be produced and the number of workers to be employed. When real wage rate rises, two effects work in opposite direction. In other words, in Figure 3.5 MV represents aggregate expenditure or aggregate demand (AD) curve which slopes downward to the right. The fundamental principle of the classical theory is that the economy is self‐regulating. His theory of employment is widely accepted by modern economists. The introduction of money does not affect the result of the classical theory that problem of deficiency of aggregate demand would not be experienced by the free-market system and therefore full employment of labour is guaranteed. The central argument of The General Theory is that the level of employment is determined not by the price of labour, as in classical economics, but by the level of aggregate demand.If the total demand for goods at full employment is less than the total output, then the economy has to contract until equality is achieved. The demand for labour is derived from this short-run production function that is, diminishing marginal product of labour. Further, assuming that the firms which undertake the task of production attempt to maximise profits, they will employ labour until the marginal product of labour is equal to the given real wage rate. Given wage-price flexibility, there are automatic competitive forces in the economic system that tend to maintain full employment, and make the economy produce output at that level in the long run. We consider what determines real output. Expenditure so made will be equal to the value of output produced. With this at the initial rate of interest i0, the supply of savings exceeds investment by KE. Real-wage is too high because money-wages don’t adjust and this goes back to the notion that workers refuse to accept money-wage cuts. It may be noted that MV in the quantity theory of money repre­sents aggregate expenditure on goods and ser­vices made in a year. Indeed, the rise in price level will be proportional to the increase in quantity of money.

At the lower rate of interest, more would be borrowed for investment. In other words, at real wage rate (W/P)1, AB workers will be unemployed. theory) Classical macroeconomics: o Output is always at full employment (equilibrium) level o Only full-employment points could be positions of even short-run equilibrium o There is perfect information Classical economics o Output is not always at full employment (equilibrium) level o There can be no full-employment in the short-run The classical theory assumes that in the short run when population does not vary, supply curve of labour slopes upward. Content Filtrations 6. This framework is composed of an aggregate production function, the labour market, the money market, and the goods market. Employment-Output Determination: Labour Market: Let us first consider the labour market where […] To produce this good we require two factors of production: (1) Labour which we denote by N and (2) capital which we denote by K. Thus we have the following aggregate production function, In the short run the stock of capital (i.e. But, in the short ran, the stock of fixed capital and wage goods inventories are given and constant. 3.5 we have shown aggregate supply curve as a vertical straight line which shows that whatever the price level, aggregate output remains constant. The Classical school was created before Keynes and their theories were seen as the staple theories to follow when it came to economic theory. 3. But with increase in money supply, money wages and price level change in such a way that real wage rate in the equilibrium situation remains constant and equilibrium in the labour market is auto­matically restored. Their conviction in wage flexibility. Second, real wage rate changes quickly to bring about equilibrium between demand for and supply of labour. The description of the various equations in the model is as follows: 1. Say's Law of Market. Thus, a firm will employ so much labour at which. However, in the classical full employment model this excess supply of labour (i.e. (1968) “The Role of Monetary Policy” American Economic Review, March. The loan market will be in equilibrium at the rate of interest at which the demand for investment is equal to the supply of savings. This will cause deficiency of aggregate demand which will cause fall in output and employment and the emergence of involuntary unemployment. First, it is because saving and investment are excluded from the system so that entire income is spent on consumer goods. It needs to be emphasised that under such condi­tions, two things ensures full employment. If due to the increase in supply of money price level rises, with a given money wage rate (W), real wage rate, which is equal to W/P, will fall. They argued that every rupee saved by households will be invested by businessmen, that is, investment expenditure will be equal to savings done by households. Keynes's theory of the determination of equilibrium real GDP, employment, and prices focuses on the relationship between aggregate income and expenditure. Thus, shift in investment demand curve to the left results in lowering of rate of interest which leads to more investment and consumption demand so that aggregate demand is not affected. Determination of Income and Employment in the Short Run without Saving and Investment: According to the classical theory, the magnitude of national income and employment depends on the aggregate production function and the supply and demand for labour. How much output will be produced in this full employment situation can be readily known from the aggregate production function. ... output, and employment. Content Guidelines 2. DETERMINATION OF EMPLOYMENT AND OUTPUT IN THE CLASSICAL MODEL Assumptions The classical theory of employment is based on the following assumptions: Individuals are rational human beings and are motivated by self-interest. In the absence of saving and investment which we are assuming here, classical economists ruled out the possibility of deficiency of aggregate demand on the basis of Say’s law. In general terms at the micro level a production function expresses the maximum amount of output that a firm can produce from any given amounts of factor inputs.” (Snowdon 2005 p. 39), “Classical full employment equilibrium is perfectly compatible with the existence of frictional and voluntary unemployment, but does not admit the possibility of involuntary unemployment. 3.6. 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. Adam Smith wrote a classic book entitled, 'An Enquiry into the Nature and Causes of the Wealth of Nations' in 1776.Since the publication of that book, a body of classic economic theory was developed gradually. Individuals do not suffer from money illusion. This implies that aggregate supply curve of output is perfectly inelastic. In this way classical theory denies the possibility of involuntary unemployment. Classic editor History Talk (0) Share "The classical neutrality proposition implies that the level of real output will be independent of the quantity of money in the economy. Consider Fig. Since no part of income is saved as is being assumed here the entire income will be spent on consumer goods produced. The key difference between classical and neo classical theory is that the classical theory assumes that a worker’s satisfaction is based only on physical and economic needs, whereas the neoclassical theory considers not only physical and economic needs, but also the job satisfaction, and other social needs.. It follows from above that the equality between investment and saving, brought about by changes in the rate of interest, would guarantee that aggregate demand for output would be equal to aggregate supply of output. Introduction The classical economists believed in the existence of full employment in the economy. The reason for this is that changes in price level causes equal proportionate changes in money wage rate with the result that the equilibrium real wage rate which is given by W/P remains constant and there­fore equilibrium level of employment does not get affected. Therefore, in Fig. This is the substitution effect. Classical Model of Employment: The classical theory of employment can be summarises in equation model given below: Product Market: 1. Other architects of the theory were Ricardo,John Stuart Mill and J.B Say. To them, full employment was a normal situation and any deviation from this regarded as something abnormal. QUESTION:Compare and contrast the classical economist and the neo classical economist theory of employment and output QUESTION:Compare and contrast the classical economist and the neo classical economist theory of employment and output Classical supply more labour hours) and thereby substitutes income for leisure. This excess supply of savings will put downward pressure on the rate of interest and as result interest will fall to i1, at which saving and investment are again equal. The quantity of money, according to the classical theory, determines only the price level of output and in no way affects the real magnitudes of saving and investment. According to Keynes full employment is not a normal situation as stated in the Classical theory. This equilibrium between supply and demand for labour at the real wage rate W/P implies that all those who offer their labour services at this wage rate are in fact employed. Suppose quantity of money in the economy is equal to M1. In fact, output produced consists of consumer goods and capital goods. Image Guidelines 5. Say’s law that “supply cre­ates its own demand” holds and full employment of labour is guaranteed. 1. Besides, with the increase in money supply and consequent change in the price level, saving-investment equilibrium will not be disturbed and therefore deficiency of aggregate de­mand will not arise. It may be noted that real wage is the opportunity cost or relative price of lesiure. the classical theory of employment The basic contention of classical economists was that if wages and prices were flexible, a competitive market economy would always operate at full employment. Thus, rewriting the aggregate production function we have. Now, with increase in money supply to M2, velocity of money V remaining constant, aggregate expenditure will rise to M2V and aggregate demand curve will shift to the right to AD2 position. To clarify further the restoration of full employment of labour due to quick adjustment of real wage rate let us consider the decrease in demand for Y labour following the fall in aggregate demand for output as it hap­pens when depression or re­cession occurs in the economy. Assumption of Full Employment(there could be … The investment demand is stipulated to be decreasing function of the rate of interest . We depict this in Fig. If this does not happen, then the problem of insufficient demand for the output (i.e., corn) will emerge which will ultimately lead to reduction in output and employment and hence to the emer­gence of involuntary unemployment. 2. and the state of technology which do not change in the short run. Consider Fig. Assumptions of Classical Theory of Y ,O, N: Money-wage stickiness. (a) Classical Theory of Employment. Determination of income and employment: Role of money and prices. Classical Model: Determination of Income and Employment with Saving and Investment: In applying Say’s law that supply creates its own demand an invalid assumption was made above that entire income earned by the households will be actually spent. Now, an important question to enquire is what guarantees that output produced by the full em­ployment of labour and the level of capital (assumed as fixed in the short run) will be actually de­manded. Keynes's aims in the General Theory. Now, according to clas­sical theory, with a fixed capital stock as employment of labour increases, marginal product of labour would di­minish. At a real wage rate lower than the equilibrium real wage rate, the quantity demanded of labour will exceed the supply of labour. Due to the excess supply of savings, the rate of interest would fall to i. The term ‘Classical’ as we will be using it was explained in Chapter 1. When the classical economists speak of The price level will change in response to demand, the What is not spent on consumer goods is saved and investment expenditure on capital goods made by businessmen equals this savings. It will be seen from Fig. To show this let us assume that the economy produces one homogeneous and divisible good, say corn. It is possible to have macroeconomic equilibrium at less than full employment. Thus, if a part of income is saved (that is, not spent), supply of output produced would not create sufficient demand for itself. 3.1 that excess supply of labour equal to AB would emerge. Classical theory regards aggregate supply curve to be perfectly inelastic. In economics, the Keynesian theory was first introduced by British economist John Maynard Keynes in his book The General Theory of Employment, Interest, and Money which was published in 1936 during the Great Depression. On the basis of their theory they denied the possibility of the existence of involuntary unemployment in the economy. Further, since quantity of money determines the price level of output, it also affects real wage rate, that is, the ratio of money wages and the price level, or W/P. Thus, supply goes on creating its own demand and Say’s law applies. Aggregate supply curve describe the relationship between aggregate supply of output with price level. Classical Theory of Output and Employment Propounded by Adam Smith in his classic entitled ‘An Inquiry into the Nature and causes of the Wealth of Nations’. 3.2 where in addition to the supply of and demand for labour, the aggregate production func­tion (OY) representing the relation between em­ployment of labour (N) and total output (K) is shown. //]]> It also depends on the extra unit of output that an additional worker can produce if added to the current workforce. Keynesian Theory of Income and Employment: Definition and Explanation: John Maynard Keynes was the main critic of the classical macro economics. "The classical neutrality proposition implies that the level of real output will be independent of the quantity of money in the economy. Classical Theory of Employment and Output Determination. [CDATA[ The Economic System is self-adjusting to full employment. Perfect competition exists in both product market and factor market. He argued that economy's equilibrium level of output and employment may not always correspond to the full employment level of income. Classical Theory of Income and Employment: Aggregate Demand, Money and Prices: Now, we shall examine how full employment of labour is assured in the classical theory even when money is introduced in the system. Suppose that in labour-market equi­librium money wage rate W1 and given the price level equal to P1 and the equilibrium real wage rate will be W1/P1. Determination of income and employment when there is no saving and investment; 2. However, classical economists denied the possibility of deficiency of aggregate demand even when a part of income is saved by the households. Classical Theory of Employment: Definition and Explanation: Classic economics covers a century and a half of economic teaching. At a lower real wage rate, more labour will be demanded or employed by the firms and vice versa. Prohibited Content 3. Equilibrium level of employment along with real wage rate is determined by labour market equilibrium, that is, equilibrium between demands for the supply of labour. Thus, quantity demanded will be equal to the supply of output produced. Quantity theory of money is generally expressed by Fisher’s equation of exchange, income version of which is stated as under: V – Income velocity of circulation of money, Y = Level of aggregate output (or real income). In brief, the classical explanation of output determination is such that there can be no unemployment in equilibrium. The main propositions of the theory are given below: (i) Total employment = total output = total income. A key component of the classical model is the short-run production function. On the other hand, with a rise in real wage rate individuals become relatively richer than before, and this induces them to consume more of all commodities (including leisure which is regarded as a normal commodity). Therefore, with a fixed capital stock and a given and constant tech­nology, the output Y (or what is also the real income) would increase only when employment of labour N in­creases. 3.Money does not matter: the classical economists treat money only as a medium of exchange .In their terms the role of money is only to facilitate transaction and has no deterministic impact on output and employment.The level of output and employment is determined by availability of real resources in the market: labor and capital. It therefore follows that at the real wage (W/P)0, there is no involuntary unemployment, or, in other words, full-employment of labour prevails. Thus demand function for labour can be written as. In other words, there is no involuntary unemployment of labour in this equilibrium situation. The classical theory has failed to explain the occurrence of trade cycles. It will be seen that intersection of investment demand curve II and the supply of savings curve SS determines the rate of interest i. This is illustrated in Figure 3.4, where initially saving and investment are in equilib­rium at rate of interest i0. It was J. M. Keynes who first analyzed the frequent problem of unemployment and fluctuating levels of real output or national income. The bar over the symbol K for capital indicates that stock of capital is fixed.
