Final answer:
A shift in the short-run aggregate supply (SRAS) curve to the right will result in a greater real GDP and downward pressure on the price level, if aggregate demand remains unchanged. Productivity increasing will shift the SRAS curve to the right.
Step-by-step explanation:
A shift in the short-run aggregate supply (SRAS) curve to the right will result in a greater real GDP and downward pressure on the price level, if aggregate demand remains unchanged.
Out of the given options:
- Commodity prices increasing will not shift the SRAS curve to the right, but it may affect the price level.
- Productivity increasing will shift the SRAS curve to the right, as it leads to more output being produced at the same price level.
- Nominal wages decreasing will shift the SRAS curve to the right, as it lowers production costs and allows firms to produce more at the same price level.
- Government spending decreasing will not directly shift the SRAS curve but may affect aggregate demand, which can indirectly impact the SRAS curve.
The correct answer is b- left if productivity increases.
