Several factors such as change in the cost of production, natural conditions, emergence of new technology, government policies, etc. affect supply and cause a shift in the supply curve. When there are changes in the quality and quantity of labor and capital, the changes affect both the short-run and long-run supply curves.
A change in the price of the product itself is not among the factors that shift the supply curve. Although a change in price of a good or service causes a change in quantity supplied or a movement along the supply curve for that specific good or service, it does not cause a shift in the supply curve itself
