Time Elapsed Since Price Change (Supply)

As time passes after a price change, it becomes easier to change production plans and supply becomes more elastic. For some items (fruits) it is difficult or perhaps impossible to change the quantity supplied immediately after a price change. Manufactured goods also have an inelastic supply if production plans have had only a short period in which to change. As time passes, the elasticity of supply increases. Supply is extremely elastic for most manufactured items.
