Answer:
Consumption Function : Relationship between Consumption Spending & Income
Consumption Function Slope = Marginal Propensity Curve (MPC)
Change in Consumption = Change in Income X MPC
Explanation:
Consumption Function is the curve representing relationship between Consumption spending and Income.
C = a + bY ; where :- C = Consumption , Y = Income , a = Autonomous Consumption i.e consumption at 0 level of income , b = MPC i.e additional consumption consumed from additional income = ΔC / ΔY
b = MPC i.e change in C due to additional change in Y = ΔC / ΔY is the slope of Consumption Function
MPC = ΔC / ΔY .
So, change in consumption i.e ΔC = MPC X ΔY
