In discussing the supply curve, economists use phrases like, "if the price rises" or "if the price falls," because:
they are uninterested in all of the other directions in which a price can move.
all sellers have control over the prices at which they sell.
they do not believe that prices are ever stable.
the supply curve shows how sellers will respond to price changes but by itself does not explain how prices are determined.
