Negative saving is nothing but dissaving, this means that at zero level of income there is dissaving of amount -a. Multiplier tells us what will be the final change in the income, as a result of change in investment. At a fixed price the value of ex-ante aggregate demand for final goods is the sum of ex-ante consumption expenditure C and ex-ante investment expenditure I on final goods. APC can be greater than one when the consumption exceeds the income. The Classical Vs.Keynesian Models of Income and Employment! : if the income is 1000 and the consumption is 1200, APC =1200/1000=1.20. Investment means addition to the stock of capital good, in the nature of structures, equipment or inventory. The coefficient (1-b) measures the slope of the saving function. Suppose the consumption equals c= 40 + 0.75 y, Investment equals I = Rs 60 and Y= C + I. Involuntary unemployment refers to a situation in which people are ready to work at prevailing wage rate, but do not find work. Zigya App .

CBSE Class 12 Ecomonics - Determination of Income and Employment. Income minus consumption is saving. autonomous consumption. The relationship between investment demand and the rate of interest is called investment demand function. This can be seen with the help of schedule and a diagram. The total expenditure is equal to the national income, which is equivalent to the national output. Calculate. e.g. Saving is equal to income minus consumption (y=c+s).The saving function relates to the level of savings to the level of income. APC= ratio of total consumption to total income. The Classical model, as outlined in Chapter 3, shows an economy in which permanent unemployment is not possible. 500 crores. What will be the equilibrium level of income?

An increase in investment leads to total rise in national income by Rs. APC=C/Y APS=S/Y Propensity to save curve Is drawn from propensity to consume curve When Y=C APC=1 Till that point APS is negative at point‘s’, AS=C+S AS=Y (refers to countries national income). If MPC is 0.9 what is the increase in investment? Ex post investment may differ from ex ante investment when the actual sales differ from the planned sales and the firms thus face unplanned addition or reduction of inventories. The equilibrium income is the level of income where AD=AS i.e….AD=AS and planned saving equals planned investment. It is directly related to MPC. =1000[1/1-4/5] = 1000×5/1=Rs. Calculate multiplier, MPC and MPS. Determination of Equilibrium Level 7. 2. The 45° line represents point at which AD and output are equal. 1. 1000 crores and consumption expenditure is Rs.750 crores. Having discussed the two theories in the foregoing pages, we can now make the following comparison: Classical Theory Keynesian Theory. In an economy the MPC is 0.95 investment is increased by Rs. The saving function is S= -a+ (1-b) Y.-a represents the intercept term and it represents the amount of savings done when there is zero level of income. Question numbers 1-10 and 18-27 are very short-answer questions carrying 1 mark each. In the short period price is fixed (constant) and elasticity of supply is infinite i.e., supply curve is perfectly elastic. Assumptions 4.
