\nAnswer:
\nAccording to J.M.Keynes, investment refers to an addition to the nation\u2019s physical stock of capital goods like roads, bridges, buildings, machines etc.<\/p>\n

Question 4.
\nWhat is MPC?
\nAnswer:
\nMPC (Marginal Propensity to Consume) refers to the ratio of change in consumption to the change in income.

Question 1.
\nDefine Income as per J.M. Keynes.
\nAnswer:
\nAccording to J.M.Keynes, Income refers to total money remuneration received by four factors of production in the form of rent, wages, interest and profit. It is expressed as follows:
\nY = C + I where, Y is income, C is consumption expenditure and \u2018I\u2019 investment expenditure.<\/p>\n

\"KSEEB<\/p>\n

Question 2.
\nHow is saving equal to investment?
\nAnswer:
\nThe equality between saving and investment is through the mechanism of rate of interest. If the saving is more than investment, the rate of interest falls, investment increases and savings comes down. When the saving is less than investment, rate of interest increases and investment comes down and the savings gets increased to the level of investment.<\/p>\n

According to Keynes, Y = C + S and Y = C + I, therefore C + S = C + I, so S = I
\nY-income, C-consumption, S-savings, I-investment.<\/p>\n

Question 3.
\nState the factors which influence Marginal Propensity to Consume(MPC).
\nAnswer:
\nThere are two main factors which affect the Marginal Propensity to Consume viz., Subjective factors and Objective factors. The subjective factors include psychological characters of human beings, social practices and institutions etc. The objective factors include, change in the wage level, changes in fiscal policy, change in expectations, change in rate of interest etc.<\/p>\n

Question 4.
\nBriefly explain the relationship between multiplier and MPC.
\nAnswer:
\nThe effect of multiplier depends on Marginal propensity to consume as its value is determined by MPC alone. If MPC is higher, multiplier will also be higher. The multiplier can be calculated by the following formula:<\/p>\n

    Question 1.
    \nWhat is investment? Briefly explain the various types of investment.
    \nAnswer:
    \nAccording to J.M.Keynes, investment refers to an addition to the nation\u2019s physical stock of capital goods like roads, bridges, buildings, machines etc.<\/p>\n

    The types of investment are as follows:
    \n1. Private Investment and Public Investment: Private investment is that investment which is undertaken by private individuals, enterprises, industrialists etc. Public investments are those investments which are made by Government authorities. The intention of private investment is profit and public investment is social benefits.<\/p>\n

    2. Induced Investment and Autonomous Investment: Induced investment is made by the people as a result of change in their income level. It is profit or income motivated. So, it is income elastic. The autonomous investment is public investment which is independent of the level of income. It is income inelastic. It is influenced by innovations, growth of population, social and legal institutions etc.<\/p>\n

    3. Ex-ante Investment and Ex-post Investment: Ex-ante investment is that investment which is actually planned according to objectives and investment is made. This investment is planned in advance. The ex-post investment is that investment which cannot be planned in advance. It is that investment which arises instantly during the course of production process.<\/p>\n

    4.\u00a0 Gross Investment and Net Investment: Gross investment is the total value of the asset made or created. It includes buildings, dams, roads, railways, industries, etc. The net investment is obtained by deducting depreciation from Gross Investment.<\/p>\n

    Question 2.
    \nExplain the J.M.Keynes consumption function in brief.
    \nAnswer:
    \nThe consumption function also called as propensity to consume refers to income consumption relationship. It is a functional relationship between Total consumption and Gross national income. The consumption function may be represented as follows:
    \nC = f (Y). where C is consumption, Y is income and f is die functional relationship.<\/p>\n

    In fact, consumption function is a schedule of the various amounts of consumption expenditure corresponding to different levels of income. The following table shows the imaginary consumption schedule:<\/p>\n\n\n\n\n\n\n\n\n\n\n
    Income (Y) in crores<\/strong><\/td>\nConsumption(C) in crores.<\/strong><\/td>\n<\/tr>\n

    300<\/td>\n240<\/td>\n<\/tr>\n
    360<\/td>\n280<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    The above table shows that the consumption is an increasing function of income because consumption expenditure increases with increase in income. When the income is zero, people spend out of their past savings on consumption because they must eat to live. When income is 50 crores, it is still not sufficient to meet the consumption expenditure of the community as the consumption expenditure (Rs. 60) is more than the income (Rs. 50).<\/p>\n

    When the income is equal to 120 crores the consumption is also Rs. 120 crores. After this stage, income is shown to increase by 60 crores (240 – 180) and the consumption goes up by only 40 crores (160 -120). This implies that increase in consumption is less than the corresponding increase in income.<\/p>\n

    \"2nd<\/p>\n

    In the above diagram, income is measured horizontally and consumption is measured vertically. 45 degree is the unity line where at all levels income and consumption are equal. The C curve is a linear consumption function based on the assumption that consumption changes by the same amount. Its upward slope to the right indicates that consumption is an increasing function of income.<\/p>\n

    B is the break-even point where C = Y or OY1 <\/sub>= OC1<\/sub>. When income rises to OY2<\/sub>, consumption also increases to OC2<\/sub>, but the increase in consumption is less than the increase in income, CC1 <\/sub><\u00a0 Y1<\/sub> Y2<\/sub>. The portion of income not consumed is saved and represented as SS1<\/sub>.<\/p>\n

    Question 3.
    \nExplain the investment function of Keynes in brief.
    \nAnswer:
    \nGenerally, investment means buying shares, stocks, bonds, securities existing in stock market. According to J.M.Keynes, investment refers to real investment which adds to capital stock. It leads to increase in level of income and production by increasing the production and purchase of capital goods.<\/p>\n

    Investment is the production or acquisition of real capital assets during any period of time. Capital and investment are related to each other through net investment. As the income of the community increases, consumption also increases. But, it does not increase in the same proportion. There will be a gap between income and consumption. The gap must be filled by increasing employment and production. For this, investment is needed.<\/p>\n

    The decision to invest in a new capital asset depends on whether the expected rate of return on the new investment is equal to or greater or less than the rate of interest to be paid on the funds needed to purchase this asset. It is only when the expected rate of return is higher than the interest rate that investment will be made in acquiring new capital assets.<\/p>\n

    In reality, there are three factors that are taken into consideration while making any investment decision.
    \nThey are as follows:<\/p>\n

      \n
    1. The cost of capital asset.<\/li>\n
    2. The expected rate of returns during its lifetime.<\/li>\n
    3. Market rate of interest.<\/li>\n<\/ol>\n

      \"KSEEB<\/p>\n

      Question 4.
      \nExplain the concept of Multiplier of Keynes.
      \nAnswer:
      \nAccording to Keynes, Multiplier establishes a precise relationship, given the propensity to consume, between aggregate employment and income and the rate of investment. It tells us that, when there is an increment of investment, income will increase by an amount which is K times the increment of investment. It can be expressed as follows:
      \nK = \u2206Y\/\u2206I, where \u2206Y is the change in income and \u2206I is the change in investment and K is the multiplier.<\/p>\n

      Problem: If the investment increases from Rs.1000 crores to Rs.1500 crores, income may increase from Rs.2000 to Rs.3000 crores, then find the multiplier.<\/p>\n

      \"2nd<\/p>\n

      In the multiplier theory, the important element is the multiplier coefficient, K which refers to the power by which any initial investment expenditure is multiplied to obtain a final increase in income. The value of multiplier is determined by the MPC. The higher the rate of MPC, the higher is the value of multiplier and vice versa.<\/p>\n

      The effect of multiplier depends on Marginal propensity to consume as its value is determined by MPC alone. If MPC is higher, multiplier will also be higher. The multiplier can be calculated by the following formula:
      \nIf MPC is deducted from I, we get MPS i.e., Marginal Propensity to Save. Now the above formula becomes as follows:<\/p>\n

      \"2nd<\/p>\n

      If MPC is deducted from I, we get MPS i.e., Marginal Propensity to Save. Now the above formula becomes as follows:<\/p>\n

      \"2nd<\/p>\n

      Working of Multiplier: Multiplier works both forward and backward. In forward working, an increase in investment leads to increased production which creates income and generates consumption expenditure. This process continues in dwindling series till no further increase in income and expenditure is possible.<\/p>\n

      In backward operation, the multiplier operates backward. A reduction in investment will lead to contraction of income and consumption which, in turn, will lead to cumulative decline in income and consumption till the contraction in aggregate income is the multiple of the initial decrease in investment.<\/p>\n

      The size of multiplier varies directly with the size of the MPC. The working of multiplier can be illustrated with the help of the following diagram:<\/p>\n

      \"2nd<\/p>\n

      In the above diagram, the original investment is I.I (OI) and the original income is OY. S…S is the saving curve. The two curves intersect at point E. If there is an increase in investment, then the I..I curve will shift to a position above the earlier level to I,…I. Now, curves I,..I, and S..S intersect at point E1 <\/sub>and the new level of income OY1<\/sub> is determined. This emphasizes the fact that an initial increase in investment leads to a large increase in income.<\/p>\n

      Question 5.
      \nWhat is Multiplier? What is its importance?
      \nAnswer:
      \nAccording to J.M. Keynes, Multiplier establishes a precise relationship, given the propensity to consume, between aggregate employment and income and the rate of investment. It tells us that, when there is an increment of investment, income will increase by an amount which is K times the increment of investment. It can be expressed as follows:
      \nK = \u2206Y\/\u2206I, where \u2206Y is change in income and \u2206I is Change in investment and K is the multiplier.<\/p>\n

      The concept of multiplier is an important contribution of Keynes to the theory of income, output and employment.
      \nThe importance of multiplier is as follows:<\/p>\n

        \n
      • The theory of multiplier highlights the importance of investment in income and employment theory.<\/li>\n
      • The multiplier throws a spotlight on the different phases of the business cycles.<\/li>\n
      • It helps in bringing equality between saving and investment.<\/li>\n
      • It is an important tool in formulating economic policies.<\/li>\n
      • It provides guidelines to achieve full employment.<\/li>\n
      • It highlights the importance of deficit financing (Public expenditure greater than public revenue).<\/li>\n
      • It points out the role of public investment in economic development.<\/li>\n<\/ul>\n

            The types of investment are as follows:
            \n1. Private Investment and Public Investment: Private investment is that investment which is undertaken by private individuals, enterprises, industrialists etc. Public investments are those investments which are made by Government authorities. The intention of private investment is profit and public investment is social benefits.<\/p>\n

            2. Induced Investment and Autonomous Investment: Induced investment is made by the people as a result of change in their income level. It is profit or income motivated. So, it is income elastic. The autonomous investment is public investment which is independent of the level of income. It is income inelastic. It is influenced by innovations, growth of population, social and legal institutions etc.<\/p>\n

            3. Ex-ante Investment and Ex-post Investment: Ex-ante investment is that investment which is actually planned according to objectives and investment is made. This investment is planned in advance. The ex-post investment is that investment which cannot be planned in advance. It is that investment which arises instantly during the course of production process.<\/p>\n

            4. Gross Investment and Net Investment: Gross investment is the total value of the asset made or created. It includes buildings, dams, roads, railways, industries, etc. The net investment is obtained by deducting depreciation from Gross Investment.<\/p>\n

            Determinants of Investments:
            \nThe investment depends on two factors viz., Marginal efficiency of Capital and rate of interest.
            \na) Marginal Efficiency of Capital (MEC): The MEC is the highest rate of returns expected from an additional unit of a capital asset over its cost. According to Kurihara \u201c MEC is the ratio between the prospective yield of additional capital goods and their supply price\u201d. The prospective yield is the aggregate net returns from an asset during its lifetime, while the supply price is the cost of producing the asset.<\/p>\n

            If the supply price of a capital asset is Rs.20;000 and its annual yield is Rs.2,000, the Marginal Efficiency of this asset is 2000\/20000 x 100\/1 = 10%. The MEC is the percentage of profit expected from a given investment on a capital asset.<\/p>\n

            b) Rate of Interest: The investment is also determined by the rate of interest. If the rate of interest is higher, the investment will be low as MEC becomes less. If the MEC is higher than the rate of interest, there will be a tendency to borrow funds in order to invest in new capital assets. If the MEC is lower than the rate of interest, no firm will borrow to invest in capital assets. Thus the equilibrium condition for a firm to hold the optimum capital stock is where the MEC is equal to the interest rate.<\/p>\n
