Question 1
Which one of the following represents the increase in the quantity supplied of the real GDP due to the increase in the price level?
- A.The right wards shifts of the aggregate supply curve
- B.The left ward shifts of the aggregate supply curve
- C.The down wards movement along the aggregate supply curve.
- D.The upwards movement along the aggregate supply curve
Show the answer and explanation
Answer: D The upwards movement along the aggregate supply curve
Why
A change in the price level moves the economy along a fixed aggregate supply curve. Because the short run AS curve slopes upward, a higher price level makes firms willing to sell more real output, so the economy slides up the curve.
A shift of the whole curve (options A and B) comes from something else, such as a change in wages, input prices or technology, and not from the price level itself.
