Explain the change in yduring the first and the second round in response to the increase in g by 150 millions. Then, analytically derive the multiplier.

y0=1000

change in g= 150

mpc=c'=0.8

mpt=t'=0.1

mpi=nx'= -0.1

g'y=-0.2

i'1=-5

i'2=-5

g'r=-10

i'=-10

k'=0.2

l'=-10

m=500

P0=20

dp/dy|s=0.02

what is round 1st?

what is round 2nd round?

what is the equilibrium y?
