An economy is in equilibrium. Find 'autonomous consumption' from the following : National income = 1,000 Marginal propensity to consume = 0.8 Investment expenditure = 100

Answer»

Solution :GIVEN
Y = 1,000
MPC (c ) =0.8
I=100
AUTONOMOUS consumption `(BARC)`=??
We know that at equilibrium,
Y=C+I
i.e. 1,000 = `barC`+cY+I
implies `1,000=barC+0.8xx1,000+100`
`implies 1,000=barC+900`
`implies 1,000-900=barC`
so, `barC=100`
