From the data given below about an economy. Calculate (a) investment expenditure and (b) consumption expenditure (i) Equilibrium level of income 5000 (ii) Autonomous consumption 500 (iii) Marginal propensity to consumer 0.4

Answer»

Solution :Income Y = 5,000, AUTONOMOUS CONSUMPTION, `bar(c) = 5000, MPC, bar(c) = 0.4`
Income = Y = Rs 5000
`MPC = c = 0.40`
Now `C = bar(c) + cY`
`bar(c) = 500 + 0.40 xx 5000`
`bar(c) = 500 + 2000`
`bar(c) = 2500`
`Y = C + I`
`5000 = 2500 + I`
`I = 2500`
`:.` (a) I = Rs 2500
(b) c = Rs 2500
