Ans: Equilibrium level of income S= I -10 + 0.2y = -3 + 0.1y 0.2y – 0.1y = -3 + 10 0.1y =7 y = 70, Components of equation c=20 + 0.90y explained in % mark question number 1, The schedule for consumption is as follows, C= 20 + 0.9 x 350 + 335 C= 20 + 0.9 x 400 = 380, Under short run fixed price, equilibrium output and equilibrium demand at fixed price and constant rate of interest can be found with the help of following formulas Y= “A, Thus, value of equilibrium output (y) depends on values of A (i.e, c + I) and b i.e AD = AS. 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. Aggregate supply is perfectly elastic at this price. The Keynesian Theory of Employment is a product of the world-wide depression of 1931-36.

At OB level of income consumption is equal to income, so saving are zero. Out of this total increase in the income Rs 4000 will be consumed and Rs 5000 be saved. Given below is the consumption function in an economy C=100+0.10Y. The equilibrium income is the level of income where AD=AS i.e….AD=AS and planned saving equals planned investment. According to the classical economics equilibrium level of income is attained always at full employment level i.e. So -a is the starting point of saving curve. = A + by (A = C + I showing total autonomous expenditure), In an economy an increase in investment leads to increase in national income which is three times more than the increase in investment (calculate marginal propensity to consume).

Full employment … Calculate the total increase in income and consumption expenditure, 11 In an economy investment expenditure increased by Rs.700 crores. The equilibrium of national income occurs where AD is equal to AS. Multiplier (k) =Ay/AI. 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. we also assume that Aggregate Supply at this cost price is determined by aggregate demand which is known as Effective demand principle. According to this theory, in an economy income and employment are in equilibrium at the level at which Aggregate Demand (AD) = Aggregate Supply (AS). Problems of excess demand and deficient demand. This came to be known as the Keynesian theory of income and employment, which has impacted many principles and practices of macroeconomics and the way economic policies are formed.
