The initial position is at point A, producing output quantity Y₁ at price level P₁. The occurrence of a supply shock in this case an increase in the oil price has an adverse effect on aggregate supply: the supply curve shifts left (from AS₁ to AS₂), while the demand curve stays in the same position. The intersection of the supply and demand curves has now moved and the equilibrium is now point B; quantity has been reduced to Y₂, while the price level has been increased to P_2.
