Question

which of the following shifts would be considered an increase in quantity supplied?

\\(d_1\\) to \\(d_2\\)
\\(d_2\\) to \\(s\\)
\\(a\\) to \\(b\\)
\\(d_2\\) to \\(d_1\\)

Explanation:

Define the target concept

Using the Change in Quantity Supplied and Movement Along a Curve knowledge points
An increase in quantity supplied refers to a movement along a fixed supply curve to a higher quantity, driven by an increase in price.

Analyze the graph and options

Using the Change in Quantity Supplied and Movement Along a Curve knowledge points

• Moving from point \(A\) to point \(B\) is a movement along the upward-sloping supply curve \(S\) to a higher price and quantity.
• Shifts from \(D_1\) to \(D_2\) or \(D_2\) to \(D_1\) represent shifts in demand, not a movement along the supply curve.
• Therefore, the movement from \(A\) to \(B\) represents an increase in quantity supplied.

Answer:

• \(D_1\) to \(D_2\)
• \(D_2\) to \(S\)
• A to B (Correct answer)
• \(D_2\) to \(D_1\)
