IS & LM Vertical Conditions

[Ashish Gourav]

When is an IS or LM curve vertical?

Monetary policy shifts the LM curve left/right or top/bottom?

Fiscal policy shifts the IS curve left/right or top/bottom?

[Abhinav joshi]

Lm is vertical when demand for money is perfectly inelastic
On the otherhand IS is vertical when investment is interest inelastic

[Abhinav joshi]

Shifting actually depends on the slope of IS AND LM , if they are vertical  ( interest inelastic)then any policy will shift them left or right
But when the elasticity is less than infinity then any policy change would shift them up and down
