An economy is in equilibrium. Find Marginal Propensity to Consume from the following:
National income = 2000
Autonomous consumption = 400
Investment expenditure = 200
उत्तर
National income (Y) = 2000
Autonomous consumption expenditure = `bar(C) = 400`
Investment expenditure (I) = 200
We know that at equilibrium
` C = bar(C) + MPC(Y)`
where,
`barC` represents autonomous consumption expenditure
MPC represents marginal propensity to consume
So,
`Y = bar(C) + MPC(Y) + I`
With thegiven values
2000 = 400 + MPC(2000) + 200
2000 = 600 + 2000MPC
MPC = 0.7
Thus,marginal propensity to consume is 0.7

Which of the following statements is not correct?
Income rises from ₹50,000 to ₹60,000, consumption increases from ₹40,000 to ₹48,000. In this situation, what will be the value of Marginal Propensity to Consume (MPC)?
Identify the correctly matched pair from Column A to column B:
| Column A | Column B |
| (1) MPC = 0 | (a) K > 1 |
| (2) MPC = 1 | (b) K = Infinity |
| (3) MPC < 1 | (c) K = 0 |
| (4) MPC > MPS | (d) K < 1 |
APC can be greater than one, but MPC is always less than one. Give a reason to justify this phenomenon.
