what are the factors influencing short run aggregate supply?
changes in costs of raw materials and energy
changes in exchange rates (E/R)
changes in tax rates
what is the impact on SRAS if there’s an increase in costs of raw materials/energy?
increase in costs of raw materials increase the overall costs of production.
shifting SRAS to the left
what is the impact on SRAS If there’s a decrease in costs of raw materials/energy?
a significant discovery of natural resources, lowers energy costs.
therefore, firms can produce more at lower costs, shifting SRAS to the right.
what is the impact of an appreciation of E/R on SRAS?
a stronger domestic currency makes imports cheaper, reducing production costs.
as a result SRAS shifts to the right.
what is the impact of depreciation of E/R on SRAS?
a weaker domestic currency makes imports more expensive.
therefore SRAS shifts to the left.
what is the impact of a change in tax rates on SRAS?
higher tax rates increase costs, which reduces supply.
lower tax rates decrease costs, which increases supply.
