The IS LM and Aggregate demand curves are giving me some trouble. IF anyone can correct me, clear this up, or point me to someplace that can, I would appreciate it

The IS curve is the plot of the relationship between income and real interest rates for which (S-I) = (G-T) + (X-M).

THe LM curve is the plot of the relationship between income and real interest rates for which money supply remains constant.

S2000magician-thanks so much for this, a quick question re this please?

we know that an expansionary monetary policy shifts the AD to the right, if AD shifts to the right, that means that the entity (G-T)+(X-M) shifted to the right originally. Could you help with this please? thanks

Monetary policy would not affect the IS curve; fiscal policy affects G or T.

Monetary policy affects the LM curve: it shifts it to the right (higher money supply means a higher M/P ratio): thus, higher aggregate demand (for a given level of interest rates).
