ENERGY PRICES, AGGREGATE SUPPLY DETERMINANT: 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.

Less Demand and More Supply

Here we have demand decreasing (tastes change) and supply increasing (technological breakthrough).- A decrease in demand causes a decrease in both price and quantity.
- An increase supply causes price to decrease and quantity to increase.
- The combined effect is an obvious decrease in price but a questionable change in quantity.
- At the new equilibrium the quantity is indeterminant.
- If demand and supply curve shift in opposite directions, then quantity is indeterminant, but price is known.

AGGREGATE SUPPLY SHIFTS Changes in the aggregate supply determinants shift both the short-run aggregate supply curve and the long-run aggregate supply curve. The mechanism is comparable to that for market supply determinants and market supply. There are two options--an increase in aggregate supply and a decrease in aggregate supply. An increase in resource quantity or quality or a decrease in resource price shifts one or both of the aggregate supply curves to right. A decrease in resource quantity or quality or an increase in resource price shifts one or both of the aggregate supply curves to left.
