प्रश्न

An economy is in equilibrium. Calculate Marginal Propensity to Consume :

National income = 1000

Autonomous consumption expenditure = 200

Investment expenditure = 100

उत्तर

 

Given that

National income (Y) = 1000

Autonomous consumption expenditure `(barC)=200`

Investment expenditure (I) = 100

As we know that

National Income = Consumption + Investment expenditure

`Y=barC+cY+I`

where c is marginal propensity to consume

1000 = 200 + c(1000) + 100

700 = c(1000)

c = 0.7

Hence, marginal propensity to consume is 0.7
