Understanding Short Run Aggregate Supply (SRA) Curve: Shape and Shifts

The video tutorial explains the concept of short run aggregate supply (SRS) and its graphical representation, the SRS curve. It discusses why the SRS curve is upward sloping due to the profit motive when prices increase. The tutorial also covers how the SRS curve can shift inward or outward, depending on changes in production costs, such as labor and raw materials. These shifts affect the real output at given price levels, with inward shifts indicating reduced output and outward shifts indicating increased output.

Identify some causes of an inward shift in the short run aggregate supply curve.

What does an outward shift in the short run aggregate supply curve indicate?
