Content Guidelines 2. To them, full employment was a normal situation and any deviation from this regarded as something abnormal. Value of output produced will therefore be equal to the income generated in the process of production. What is required for stable price level is the stable money supply since quantity of money determines the price level. There is neither excess supply of labour, nor excess demand for labour. One essential feature that follows from the classical money market is that money is neutral. Further, it is the wage flexibility (i.e., changes in the wage rate) which ultimately brings about this full-employment situation. The term ‘Classical’ as we will be using it was explained in Chapter 1. On the basis of their theory they denied the possibility of the existence of involuntary unemployment in the economy. The starting point The Keynesian revolution was against “classical economics” (orthodox economics) Keynes refer to all economists before 1936 as classical economics This is wrong: o Classical economics: Economic theory (price theory) between Adam Smith’s Wealth of Nations (1776) and the marginal revolution in 1980s (C. … Of course, N0N1 workers have volun­tarily withdrawn themselves from labour force and therefore no one remains involuntarily unem­ployed. Content Filtrations 6. Further, due to operation of Say’s law and wage-price flexibility full employment of resources occur in the economy. This means that the goods market is segmented completely from the remainder of the system. J.B. Say (1764-1832), a French economist, introduced a law of markets in his book Traite d’economic politique. 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. Investment is an inverse function of the rate of interest, that is. The classical theory assumes that in the short run when population does not vary, supply curve of labour slopes upward. 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. The description of the various equations in the model is as follows: 1. This will result in deficiency of demand or expenditure on output of goods produced. How is the general price level determined? Thus, These relationships (equations 3.2, 3.7 and 3.8), together with the equilibrium condition for the labour market. Assumptions of Classical Theory of Y ,O, N: Money-wage stickiness. In fact, output produced consists of consumer goods and capital goods. Determination of income and employment when there is no saving and investment; 2. Consider Fig. Once we know the equi­librium level of employment from the aggre­gate production function we can derive the equilibrium level of output. It is due to slower growth of capital stock in the country. Thus, the problem of deficiency of aggregate demand would not be faced and full employment of labour will prevail. The aggregate demand curve for labour is the horizontal summation of all individual firm’s demand curve for labour. Classical Theory of Employment and Output Determination. 2. Quantity of money does not influence the real variables of the system- output, employment, and the interest rate. 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. 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. 4. 2. Keynesian economics is a theory of total spending in the economy (called aggregate demand) and its effects on output and inflation. We will adopt that approach here. B. Other architects of the theory were Ricardo,John Stuart Mill and J.B Say. Employment-Output Determination: Labour Market: Let us first consider the labour market where we deal with production... 2. Thus, the demand curve for labour is derived from the marginal product curve of labour. In other words, there is no involuntary unemployment of labour in this equilibrium situation. The supply of money and the demand for money jointly establish equilibrium in the money market. Summary of Keynesian Theory of Employment: Keynesian theory of employment, as developed in the General Theory is outlined in Chart-1. TOS 7. This will cause deficiency of aggregate demand which will cause fall in output and employment and the emergence of involuntary unemployment. That is, employment of labour and output (income) rise or fall together. 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’. Say’s law that “supply cre­ates its own demand” holds and full employment of labour is guaranteed. Investment may be defined as the amount of an economy’s product that is not consumed. Individuals do not suffer from money illusion. This output OYF of corn will constitute the income of the society and will be distributed between wages and profits. supply more labour hours) and thereby substitutes income for leisure. It lays emphasis on detecting errors and correcting them once they have been committed. An investment is something that is used to create value in future. The goods market equilibrium is achieved when saving is equal to investment, i.e.. A flexible interest rate in the classical system always brings equality between savings and investment. Classical Theory of Employment: Definition and Explanation: Classic economics covers a century and a half of economic teaching. Velocity of money is defined as the number of times a unit of money is used for purchase of final goods and services in a period, say during a year. As a result (as is seen from Fig. As a result of the competition among the firms to hire labour desired by them, the wage rate would go up to the equilibrium level (W/P)0. John Maynard Keynes The General Theory of Employment, Interest and Money. Before publishing your articles on this site, please read the following pages: 1. The Classical Theory of Income and Employment is premised on three conjectures. 3.6. With aggregate supply curve AS and aggregate demand curve AD1 price level OP1 is determined. Hence, given the supply and demand curves, the wage rate W/P is determined. Real variables such as, output, level of employment and real wage rate remain undisturbed following a change in money supply. Monetary sector is not concerned with relative prices and real variables. 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. the tendency of the economic systems is … According to the Classical Theory, the level of water in the "Bathtub" (employment, income, and output) is always at the maximum because _____ is (are) assumed to create Demand. where K denotes a constant capital stock and L denotes quantities of variable input, labour. Theory of Employment. Therefore, in Fig. Capital is an exogenous variable determined by the given inversion in the previous period. In the lower panel, aggregate produc­tion function has been shown. As money supply increases from M1 to M2, the price level rises proportionately from P1to P2. According to Keynes full employment is not a normal situation as stated in the Classical theory. It is thus clear that due to adjustment in interest rate even decline in investment does not give rise to demand deficiency problem and full-employment continues to pre­vail. One important conclusion from the classical model is the classical dichotomy. It will be seen that intersection of investment demand curve II and the supply of savings curve SS determines the rate of interest i. Their conviction in wage flexibility. 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). Thus, a firm will employ so much labour at which. Classicists answered this question in terms of the quantity theory of money which deter­mines aggregate demand, which, in turn, de­termines the price level. There is the existence of full employment without inflation. The classical aggregate supply curve is shown in Fig. 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. 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. Say’s law of markets is the central pillar of the whole classical theory. 3. Given wageprice flexibility, there are automatic forces in the economic system that tends to maintain full employment and produce output at that level. The law is simply a description of market exchange activity: "Supply creates its own … The effect of increase in the quantity of money is graphically shown in Fig. ADVERTISEMENTS: 3. 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. 2. 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. Project The Classical Theory Of Employment amd output The fundamental principle of the classical theory is that the economy is self-regulating. 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. The classical employment analysis is based on the Market Law of the French economist J. -Government macroeconomic policies are unnecessary and counter-productive; automatic, built-in mechanisms … 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. 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. The implication . An economy considers a number of capital projects in each time period. Lecture Note on Classical Macroeconomic Theory Econ 135 - Prof. Bohn This course will examine the linkages between interest rates, money, output, and inflation in more detail than Mishkin’s book. 3.5 we have shown aggregate supply curve as a vertical straight line which shows that whatever the price level, aggregate output remains constant. 500 crores and velocity of circulation is 4, then 500 X 4 = 2000 crores will be aggregate expenditure. Wage-Price flexibility is all that is required. However, there could be voluntary unemployment, frictional and structural unemployment. The Economic System is self-adjusting to full employment. Classical Model of Employment: The classical theory of employment can be summarises in equation model given below: Product Market: 1. The classical economist did not formulate any specific theory of employment as such. It was J. M. Keynes who first analyzed the frequent problem of unemployment and fluctuating levels of real output or national income. 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. 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. 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. 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. Now suppose that due to fall in profit expectations investment by business firms decreases by ΔI or EK causing a shift in the investment curve to the left to the new position I’I’. The marginal product schedule is the firm’s demand curve for labour. The level of output and, hence, the level of employment is established in the labour market by the demand for and supply of labour. The aggregate production function is: Y = f (K , L) … (3.2). Interest rate that guarantees that changes in the particular components of demands do not affect the aggregate level of commodity demand. (2) At the full employment equilibrium, there is no possibility of involuntary unemployment. Classical Theory of Employment and Output (With Diagram) 1. Chapter 3: Classical Macroeconomics: Output and Employment 1. On the other hand, the supply of labour by the households in the economy depends on their pattern of preference between income and leisure. TYPES OF UNEMPLOYMENT: (a) Structural Unemployment: It is also known as Marxian unemployment or long-term unemployment. What is not spent on consumer goods is saved and investment expenditure on capital goods made by businessmen equals this savings. It needs to be emphasised that under such condi­tions, two things ensures full employment. A key component of the classical model is … Equation 3.10 states that people hold cash balance since there is a gap between money receipts and expenditures. How much output will be produced in this full employment situation can be readily known from the aggregate production function. Prohibited Content 3. Thus, supply goes on creating its own demand and Say’s law applies. It undertakes those investment projects that yield a rate of return greater than the market rate of 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. So the investment would by classical theory crowd itself out as the savings will rise. The classical theory assumes full employment without inflation. 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. THE CLASSICAL THEORY OF EMPLOYMENT. On the other hand, the savings of the people are taken to be the increasing function of the rate of interest, that is, higher the rate of interest, the larger the savings and vice versa. Second, real wage rate changes quickly to bring about equilibrium between demand for and supply of labour. Due to the excess supply of savings, the rate of interest would fall to i. B. TOS4. It will be seen that ON labour is employed in this equilibrium situation. 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. 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. Indeed, the rise in price level will be proportional to the increase in quantity of money. The equilibrium level of aggregate output and employment in the classical theory of labour market is determined by the aggregate production function and the demand and supply schedules of labour. On the contrary, at a lower rate of interest, say i1 the demand for investment exceeds the supply of savings. That is. 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. between these types of activity, not the domains in which they are carried out. The corresponding equilib­rium level of output (at the equilibrium level of employment) is YF. 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. Now an important thing to know about classical theory is when due to decline in profit expecta­tions of business firms if investment falls as it happens at times of recession or depression how it then explains that demand deficiency problem would not arise and equilibrium will continue to remain at full employment. That is, economic forces would always be generated so as to ensure that the demand for labour was always equal to its supply. It is a closed economy without foreign trade. The classical theory assumed the prevalence of full employment. Thus, it is at rate of interest I that loan market is in equilibrium, i.e., investment is equal to savings (I = S). The unemployment occurs when the aggregate demand function intersects the aggregate supply function since the economy cannot experience a full employment level. More labour is demanded at a lower wage. 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. This is illustrated in Figure 3.4, where initially saving and investment are in equilib­rium at rate of interest i0. determine output, employment and real wage in the classical system. The Classical Theory The fundamental principle of the classical theory is that the economy is self‐regulating. We depict this in Fig. classical theory of output and employment. This induces the individual to work more (i.e. Keynes used his income‐expenditure model to argue that the economy's equilibrium level of output or real … Now, let us discuss the theory in detail: The Demand for Labour: The demand for labour is assumed to depend inversely on the real wage. 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. Classical economists believed that full employment prevailed in the economy through wage and price adjustments, and any deviation … Obviously, such transactions depend on the volume of money income. Classical view that forces or mechanisms exist to restore a position of full employment. Investment refers to the creation of additional stock of capital. Assumptions of Classical Theory of Y ,O, N: Money-wage stickiness. Employment-Output Determination: Labour Market: 2. 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. Factors of production earn their incomes during the process of production. 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. The adjustment process works in the following way. Assumption of Full Employment(there could be only Frictional or Voluntary Unemployment). When real wage rate rises, two effects work in opposite direction. The demand for labour is derived from this short-run production function that is, diminishing marginal product of labour. The Economic System is self-adjusting to full employment. 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. (a) Classical theory of employment (b) Keynesian theory of employment. Income and employment theory, a body of economic analysis concerned with the relative levels of output, employment, and prices in an economy. As explained above, aggregate output YF is determined by the equilibrium level of employment NF given the aggregate production function. S = S (i) – Saving Function . 1 It is true that the neo-classical theory of the firm and especially the marginal productivity theory of wages (with a given plant and equipment) imply a close or predictable relation between labor input and physical output. Suppose quantity of money in the economy is equal to M1. 3.2 that, given the stock of fixed capital and the state of technology, employment of ONF labour produces OYF output. 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. It may be noted that real wage is the opportunity cost or relative price of lesiure. It will be seen from Fig. In other words, in Figure 3.5 MV represents aggregate expenditure or aggregate demand (AD) curve which slopes downward to the right. 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. 5. the general theory of employment re-stated money-wages and prices 6. changes in money-wages o professor pigou's 'theory of unemployment' 7. the employment function 8. the theory of prices short notes suggested by the general theory 9. notes on the trade cycle 10. notes on mercantilism, the usury laws, stamped money and theories of Thus the supply function of labour can be written as, This implies that at a higher wage rate, more labour would be supplied and vice versa. The main propositions of the theory are given below: (i) Total employment = total output = total income. Let us first consider the labour market where we deal with production function in which capital stock is fixed and labour is the variable input. Share Your Word File 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.) Now, what is the rational behind the upward-sloping supply curve of labour. As explained just above, marginal product (MP) curve of labour also represents the demand curve of labour (Nd). The supply of money is fixed as it is supplied by the central bank. Plagiarism Prevention 4. Thus, investment, in the classical system, depends on the market rate of interest. According to the Keynesian theory, the changes in aggregate demand have short run effects on employment and output unlike in the prices. Content Guidelines 2. In his opinion, if it was so then why the economy was facing Great Depression? Thus sum of wages as reward for labour and total profits as reward for capital would constitute the total income of the society and would be equal to the national output OYF produced. In the classical model, equilibrium level of output is determined by the employment of labour. "The classical neutrality proposition implies that the level of real output will be independent of the quantity of money in the economy. It will be seen from the lower panel of Fig. .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. Outline the relations of monetary factors in the relationship between savings and investment. 3. Their conviction in wage flexibility. So we can say that the total demand for money in an economy is a func­tion of money national income or output. Image Guidelines 5. The Keynesian theory of employment is also called the theory of income and output. 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. Now, due to the excess demand for investment in the loan market rate of interest would go up. 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. In brief, the classical explanation of output determination is such that there can be no unemployment in equilibrium. 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, in classical theory aggregate supply curve is determined by supply-side factors, namely, preferences of households or individuals regarding work and leisure, the stock of capital (and other factor endow­ments), the state of technology. 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.

This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. 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. Although the term has been used (and abused) to describe many things over the years, six principal tenets seem central to Keynesianism. Inciden­tally, this is the full employment position, de­noted by LE = LF. Effective demand manifests itself in spending of income or the flow of total expenditure in the economy. 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. It is more concerned with the amount of output than the human beings. According to classical economists, it is the changes in the rate of interest that brings about equality between saving and investment. The entire labour force cannot be absorbed in productive employment, because there are not enough instruments of production to employ them. Now, according to clas­sical theory, with a fixed capital stock as employment of labour increases, marginal product of labour would di­minish.
