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.

What is the primary reason for the upward slope of the short run aggregate supply curve?

• Technological advancements

• Profit motive for businesses

• Increased consumer demand

• Government intervention

What happens to real output when the price level increases from P1 to P2 in the short run?

• It increases

• It remains constant

• It fluctuates unpredictably

• It decreases

Which of the following can cause an inward shift in the short run aggregate supply curve?

• Decrease in labor costs

• Increase in labor costs

• Increase in consumer spending

• Technological improvements

An outward shift in the SRS curve indicates what change in real output at a given price level?

• Fluctuation in real output

• No change in real output

• Increase in real output

• Decrease in real output

What is essential to understand about the SRS curve for economic analysis?

• Its constant position over time

• Its upward sloping shape and ability to shift both ways

• Its ability to shift only inward

• Its downward sloping nature
