Thus, with a given amount of productive resources and constant technology and with further assumption that they are fully utilised and em­ployed, the aggregate output (Y) is held constant at full-employment level of output in the short run. 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. John Maynard Keynes The General Theory of Employment, Interest and Money. In the lower panel, aggregate produc­tion function has been shown. Classical Theory of Employment. A Keynesian believes […] Before publishing your Articles on this site, please read the following pages: 1. The corresponding equilib­rium level of output (at the equilibrium level of employment) is YF. 2. The point of effective demand, which gives the equilibrium level of employment, also indicates the equilibrium level of national income and output. Indeed, the rise in price level will be proportional to the increase in quantity of money. According to Keynes, our economy always tends toward. 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. Besides, since in classical theory level of aggregate output is determined by the supply of productive resources, (i.e., capital stock, availability of labour, land etc.) Given wageprice flexibility, there are automatic forces in the economic system that tends to maintain full employment and produce output at that level. This is the substitution effect. Keynesian economics was developed by the British economist John Maynard Keynes. With this at the initial rate of interest i0, the supply of savings exceeds investment by KE. 3.2 represents money market equi­librium where we plot total money stock M on the horizontal axis and the levels of PY on the vertical axis.  Laissez … As explained just above, marginal product (MP) curve of labour also represents the demand curve of labour (Nd). Real sectors cannot influence the monetary sector and, hence, monetary variables. The quantity theory of money says that the quantity of money determines the price level. Thus, For equilibrium in the money market, = kPY … (3.12). Share Your PDF File The demand for money equation that will be presented here is the Marshallian cash balance version of the quantity theory of money. To show this let us assume that the economy produces one homogeneous and divisible good, say corn. The Classical Theory of Employment and Output! Quantity ... 1. What is required for stable price level is the stable money supply since quantity of money determines the price level. TOS4. The classical economist did not formulate any specific theory of employment as such. At low level of Labour input before N 1 ADVERTISEMENTS: The Production function is a straight line which exhibits... 2. It also depends on the extra unit of output that an additional worker can produce if added to the current workforce. Ultimately, real wage rate will decline to (W/P)F where ag­gregate labour demand is exactly matched by aggregate labour supply. The classical theory is based on the automatic self equilibrating tendency of the economic forces. Consider Fig. It is due to slower growth of capital stock in the country. 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. What is not spent on consumer goods is saved and investment expenditure on capital goods made by businessmen equals this savings. (2) At the full employment equilibrium, there is no possibility of involuntary unemployment. Suppose quantity of money in the economy is equal to M1. 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. Say’s law of markets is the central pillar of the whole classical theory. Households can be assumed to both produce and consume without altering the basic result, and there is no intrinsic need for a market for labour, as opposed to goods produced by the self-employed household. Classicists assumed that saving (S) is an increasing function of the rate of interest (r), that is. Say believed that every producer who brings goods to the market does so only to exchange them for other goods. Thus, the problem of deficiency of aggregate demand would not be faced and full employment of labour will prevail. The classical theory of employment is grounded in Says Law, the classical interest rate mechanism, and downwardly flexible prices and wages. This induces the individual to work more (i.e. TOS 7. When real wage rate rises, two effects work in opposite direction. Keynes used his income‐expenditure model to argue that the economy's equilibrium level of output or real … Other architects of the theory were Ricardo,John Stuart Mill and J.B Say. The changes in rate of interest would cause investment and supply of saving to become equal. 3.1 that supply and demand for labour are in equilibrium at the real wage rate (W/P). Classical Theory Output and Employment. Prohibited Content 3. According to classical economists, it is the changes in the rate of interest that brings about equality between saving and investment. -Government macroeconomic policies are unnecessary and counter-productive; automatic, built-in mechanisms … The classical theory assumes perfect competition in both the factor and product markets. Thus, with rise in price level, level of employment remains unchanged and, given the aggregate production function, level of output will remain con­stant. (B) Say’s Law: The classical theory of employment rules out the possibility of any general and prolonged unemployment. Classical economists believed that full employment prevailed in the economy through wage and price adjustments, and any deviation … There is neither excess supply of labour, nor excess demand for labour. However, there could be voluntary unemployment, frictional and structural unemployment. Keynes's theory of the determination of equilibrium real GDP, employment, and prices focuses on the relationship between aggregate income and expenditure. Saving implies a choice between present and future consumption. It may be noted that MV in the quantity theory of money repre­sents aggregate expenditure on goods and ser­vices made in a year. Let us first explain how in classical theory price level in the economy is determined. The short- run classical theory of income and employment can be explained through the following three stages: 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. 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. Outline the relations of monetary factors in the relationship between savings and investment. Determination of income and employment when there is no saving and investment; 2. The fundamental principle of the classical theory is that the economy is self‐regulating. Let symbol Y stand for the output of this good. 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. Note that even in this new labour market equilibrium at lower real wage rate W1/P0 full employment of labour prevails as all those who are willing to work at this real wage rate find employment. The description of the various equations in the model is as follows: 1. Content Guidelines 2. This is the famous law of di­minishing returns of the classical eco­nomics. 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. In this way classical theory denies the possibility of involuntary unemployment. 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. “General Theory of Employment, Interest, and Money” which elucidated the thoughts of Keynes as economist (Froyen, 2006). -Government macroeconomic policies are unnecessary and counter-productive; automatic, built-in mechanisms … It undertakes those investment projects that yield a rate of return greater than the market rate of interest. Privacy Policy 8. Say's Law of Market. 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. This will cause deficiency of aggregate demand which will cause fall in output and employment and the emergence of involuntary unemployment. Hence, given the supply and demand curves, the wage rate W/P is determined. Further, given the stock of capital and the state of technology with this full employment of labour, total output or income of the economy equal to OYF is determined. The Economic System is self-adjusting to full employment. It is; where Md stands for demand for money, Y the output level, P the price level and k is the fraction of Y that people want to hold to facilitate transaction. plant and equipment) is assumed to be fixed. Although the term has been used (and abused) to describe many things over the years, six principal tenets seem central to Keynesianism. Here we determine equilibrium rate of interest. 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. 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. It was J. M. Keynes who first analyzed the frequent problem of unemployment and fluctuating levels of real output or national income. At a real wage rate lower than the equilibrium real wage rate, the quantity demanded of labour will exceed the supply of labour. Thus, we see a link between money supply and the price level: an excess money supply means increasing demand for commodities that pulls up the general price level. 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 has the following characteristics: It is built on an accounting model. This is shown in Fig. THE CLASSICAL THEORY OF EMPLOYMENT. ADVERTISEMENTS: 3. Now, due to the excess demand for investment in the loan market rate of interest would go up. Of course, N0N1 workers have volun­tarily withdrawn themselves from labour force and therefore no one remains involuntarily unem­ployed. It will be seen that ON labour is employed in this equilibrium situation. 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. Quantity of money only influences the price level. With aggregate supply curve AS and aggregate demand curve AD1 price level OP1 is determined. It may be noted that real wage rate is given by nominal wage rate divided by the general price, level, that is, real wage rate = W/P where W is the nominal or money wage rate and P is the average price level. In brief, the classical explanation of output determination is such that there can be no unemployment in equilibrium. This will result in deficiency of demand or expenditure on output of goods produced. B. Further, due to operation of Say’s law and wage-price flexibility full employment of resources occur in the economy. 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. J.B. Say (1764-1832), a French economist, introduced a law of markets in his book Traite d’economic politique. Chapter 3: Classical Macroeconomics: Output and Employment 1. Content Filtrations 6. 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. (a) Classical theory of employment (b) Keynesian theory of employment. Further, according to them, rate of interest is determined by supply of savings and demand for investment. Their conviction in wage flexibility. The Classical Theory Of Employment amd output The fundamental principle of the classical theory is that the economy is self-regulating. In Fig. Equation 3.10 states that people hold cash balance since there is a gap between money receipts and expenditures. It may be added here that the volume of output and employment in the classical system are determined by only supply side of the market for output. Aggregate supply curve describe the relationship between aggregate supply of output with price level. This means that the goods market is segmented completely from the remainder of the system. The investment demand is stipulated to be decreasing function of the rate of interest . S = S (i) – Saving Function . It is to be remembered here that Y is also fixed due to the existence of full employment in the economy. At (W/P)0 to repeat, all those who offer their labour services are in fact demanded and employed. It will be seen that intersection of investment demand curve II and the supply of savings curve SS determines the rate of interest i. 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 needs to be emphasised that under such condi­tions, two things ensures full employment. Since the classical model is a supply-determined one, it says that equiproportionate increases (or de­creases) in both money wage and the price level will not change labour supply. This framework is composed of an aggregate production function, the labour market, the money market, and the goods market. In fact, the former coincides with the latter. 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. 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’. The supply of money and the demand for money jointly establish equilibrium in the money market. Therefore, in Fig. Thus, rewriting the aggregate production function we have. Once we know the equi­librium level of employment from the aggre­gate production function we can derive the equilibrium level of output. At a lower real wage rate, more labour will be demanded or employed by the firms and vice versa. 2. The Keynesian theory of employment is also called the theory of income and output. 4. 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. It was suggested there that Classical economists can be identified by what theories they hold. Compare/Contrast paper Keynesian Economics versus Classical Economics Keynesian economics is an economic theory of total spending in the economy and its effects on output and inflation. We depict this in Fig. It was J. M. Keynes who first analyzed the frequent problem of unemployment and fluctuating levels of real output or national income. Other architects of the theory were Ricardo,John Stuart Mill and J.B Say. Thus, demand for labour depends inversely on real wage. A key component of the classical model is … between these types of activity, not the domains in which they are carried out. One important conclusion from the classical model is the classical dichotomy. 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). 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. "The classical neutrality proposition implies that the level of real output will be independent of the quantity of money in the economy. Thus, with equal proportionate increase in money wage rate as a result of rise in price level, equilibrium real wage rate and level of employment will remain unaffected. 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. 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.
