To a layman, there may not be any difference between a change in quantity supplied and a change in supply.
However, to economists, these are two distinct concepts that have different causes and effects.
In economics, change in quantity supplied refers to changes in supply for goods and services caused by a change in price while change in supply refers to changes in supply caused by non-price factors.
These two are different from one another. So, in this post, we will look critically at the difference between change in quantity supplied and change in supply.
