A two equations model below represent goods sector and marketing sector equilibrium for hypothetical economy: Y=Io/1-c+b/1-c . r Io>0,b <0,0 0,f>0, g <0,e <0 I)

A two equations model below represent goods sector and marketing sector equilibrium for hypothetical economy:

1. Y=Io/1-c+b/1-c . r Io>0,b<0,0

2. Y=Lo/f -g/f .r Lo>0,f>0, g<0,e<0

I) What are model and form of these equations?

The given factions IS-LM model and it is an explicit form

How do we know the model IS-LM and the form is explicit form explain ?
