Factors Influencing Short-run AS
- There are multiple factors that can influence the short-run aggregate supply (SRAS). These include:
- Changes in costs of raw materials and energy
- Changes in exchange rates (E/R)
- Changes in tax rates
A Table That Explains The Influences On Short-run Aggregate Supply (SRAS)
Change in Condition |
Explanation | Impact on SRAS |
|
As the price of input costs rise, fewer goods/services can be produced with the same amount of money |
SRAS decreases - shifts left |
Decrease in costs of raw materials/energy |
As the price of input costs decrease, more goods/services can be produced with the same amount of money |
SRAS increases - shifts right |
Appreciation of E/R |

SRAS increases - shifts right |
Depreciation of E/R |

SRAS decreases - shifts left |
Decrease in tax rates |

SRAS increases - shifts right |
Increase in tax rates |
Taxes represent an additional cost for firms Increasing taxes = increase in costs Higher costs = less output |
