whatis therelationshipbetweenMPCand MPS? Explain ?

Answer»

Solution :sum of MPCand MPSis alwaysequalto 1.How ? Income(Y)is ether consumed( C)orsaved( S) .THEREFORE,Y=C+S. increasein income`(Delta Y) `is EQUALTO increasein concumption`(DeltaC) ` andincrease in saving`(Delta S) .SoDelta Y =DeltaC+ Delta S.`Dividingbothsidesby `Delta `Y, we get
`(DELTAY) /(DELTAI) =(DeltaC)/(Delta Y) +(DeltaS)/(DeltaY)`
`1=MPC+MPS`
