It is also possible for firms to plan to reduce their investment expenditure at the same time that households plan to increase their saving. Since there is no spending firms will receive no income. John Maynard Keynes is widely misunderstood not because he is misread, but because so few take the time to read him. In each of these examples actual saving has been equal to actual investment. The process would continue until savings once again coincide with investment. 200 crores in excess of the value of current output that they plan to spend. But it was only in the third example that planned saving and planned investment were equal. We know that, out of total income, a part is consumed and another part is saved, i.e., Y = C + S. Thus, if we know APC or MPC, then we can determine APS and MPS in the following way: Thus, APC and APS are complementary concepts. Similarly, a fall in the rate of interest, ceterus paribus, will stimu­late investment. That is. Such physical or real investment creates new assets — thereby adding to the country’s productive capacity, whereas financial invest­ment only transfers the ownership of existing assets from one person or institution to another. 1,000 is invested in the new machine, the annual return is Rs. Similarly, if the Rs. Yet we stated earlier that as income increases, MPC tends to fall. For the sake of simplicity, Keynes assumed that all investment is autonomous and, hence, independent of income. It is the philosophy of Keynes which ought to catch the attention of political theory. If interest rates have been high for some time, entrepreneurs may be less inclined (willing) to undertake investment expenditure. Such an investment schedule is drawn in Fig. The General Theory of Employment, Interest, and Money By John Maynard Keynes Feburary 1936 Table of Contents • PREFACE • PREFACE TO THE GERMAN EDITION • PREFACE TO THE JAPANESE EDITION • PREFACE TO THE FRENCH EDITION Introduction 1. 700. the equilibrium level of income. If it is Rs. But, in economics, the term investment is used in a different way. At this level, and only at this level, to­tal planned expenditure of households and business firms is exactly equal to the amount of output pro­duced or income generated by the economy (i.e., to­tal planned expenditure is equal to national income). There are merely two sectors that is, consumers ( C ) and firms ( I ). Building on his theory, Keynesians have stressed the relationship between income, output, and expenditure. Thus, increased spending leads to economic expansion, or recovery, because it stimulates a growth in output, employment, and income. The equivalence of the two approaches to the theory of income determination may be alternatively shown by using algebra. contributes much to the improvement of a country’s living standards. 1. 1. In Fig. Let us consider a simple case of a machine with an indefinite return R each year. His theory of employment is widely accepted by modern economists. Content Guidelines 2. In short, the significance of investment lies in the contribution it makes to economic prosperity. The owners and suppliers of the fac­tors are largely the households. 18.7). If investment increases, aggregate demand also increases and, at the end, we observe an increase in employment and income. John Maynard Keynes wrote his esteemed book “General Theory of Employment” in 1936. 800 + Rs. It has no relation to individual’s (or society’s) income. This is the amount demand will have to increase for full employment to be achieved. Since national income = national expenditure = national output, we can write: By cancelling out C from both sides we get: This is known as saving-investment equality and is always true because it is a definitional identity rather than an equation. Since households wish to buy less than this, firms will be forced to hold stocks. The level of employment is directly related to the level of production or output (Y). To simplify his analysis, Keynes initially left aside the government sector (and, therefore, the element of government expenditure in aggregate demand). 400 to Rs. crores). We now explain the reason(s). However, this is not a general result in the sense that it does not always hold. The multiplier ignores all external economic transactions that could be significant for a country with foreign sector. When spending falls and sellers reduce their outputs, a cutback occurs in the employment of resources. OYe is, there­fore, the equilibrium level of output (income). 4 crore and the MPC is 0.7, then the consumption function will be: C = Rs. 18.6) is also called the break-even point in the theory of consumption because at this point income = consumption and the nation, as a whole, neither saves nor dis-saves. A Keynesian believes […] Given the specified spending plans, find out the equi­librium value of national income. 18.5. Since saving is that portion of income of a house­hold which is not passed on by way of further spend­ing, it exerts a contractionary influence on the circular flow of income. 100 crores, although firms originally planned to invest Rs. Now, by combining the two schedules — the upward sloping consumption schedule and the horizontal investment schedule — we get the combined C + I schedule in Fig. The Keynesian concept of multiplier is based on the following assumptions: The Keynesian multiplier comes into operation for any auto­nomous (income-independent) change in spen­ding.
