here is my understanding:
Y=C+I+G+Nx
Y= C+T+I+GT+Nx
I= (YCT)+(TG)+Nx
assuming, In closed economy Nx=0 then:
I= private savings + Public savings, if Public savings is surplus, Investment will increase.
As my memories about ISLM model, IS curve will move to the right, interest goes down, not as explained by maratikus. Budget surplus is not also necessary “lower govt spending”. |
