A supply shock in the form of higher energy prices will increase production costs and decrease short-run aggregate supply. However, in the long run, wages and prices will adjust, causing the long-run aggregate supply curve to remain unchanged. Therefore, the short-run aggregate supply curve shifts leftward, but the long-run aggregate supply curve does not shift.
