CROWDING-OUT EFFECT Definition Graphical Illustration Partial Crowding out Full Crowding out Factors that Affect the Crowding-out Summary
Definition • The increase in government expenditure will lead to the fall of private expenditure, thus resulting in a smaller multiplier effect on the equilibrium level of income. • Underlying assumption: Y I G r
r IS2 IS1 A B 0 Y Shifting of IS Curve Distance AB = Y Y1 Y2
Crowding-out Effect • Increase in G • IS curve shifts to the right by the horizontal distance (Gmultiplier) • if LM curve is upward sloping, then the rise in interest rate will lead to the fall of I • the fall of I will lead to the decrease in Y • eventual in Y is less than (Gmultiplier)

Summary • The crowding-out effect depends on • the slopes of IS & LM curves • The steeper the LM curve, the larger the crowding-out effect • The flatter the LM curve, the smaller the crowding-out effect • The existence of crowding-out effect will affect the effectiveness of fiscal policy
