A decrease in energy prices will
One of several specific aggregate supply determinants assumed constant when the aggregate supply curve is constructed, and that shifts the aggregate supply curve when it changes. An increase in the energy prices causes a decrease (leftward shift) of the aggregate supply curve.A decrease in the energy prices causes an increase (rightward shift) of the aggregate supply curve. Other notable aggregate supply determinants include technology, wages, and the capital stock.Energy prices fall under the resource price aggregate supply determinant.ne of several specific aggregate supply determinants assumed constant when the aggregate supply curve is constructed, and that shifts the aggregate supply curve when it changes.
