Question

Quizplus · Accepted Answer

A movement along a good's supply curve occurs when there is a change in the price of the good. This is because as the price of the good increases, producers have an incentive to supply more of it to the market. Conversely, if the price of the good decreases, producers have less of an incentive to supply the good, resulting in a decrease in the quantity supplied.

None of the other choices listed would cause a movement along a good's supply curve.

A) An increase in the price of an input would cause a decrease in supply, shifting the entire supply curve to the left.
C) If the production process of the good becomes more efficient, this would cause the supply curve to shift to the right, but it would not cause a movement along the existing supply curve.
D) If more firms enter the market, this would increase the overall supply of the good, resulting in a rightward shift of the supply curve.
E) If the government places a subsidy on the producer of the good, this would also increase the overall supply of the good, resulting in a rightward shift of the supply curve. However, it would not cause movement along the existing supply curve.
