So there are many sellers of the vacuum cleaner selling identical vacuum cleaners and there are many buyers . So this market is can be closest to perfect competition . All sellers charge same price and no seller has market power . So in long run all sellers earn zero economic profits . If in short run there is positive economic profit , more sellers are attracted towards the market due to free entry and exit . This causes rise in supply of the vacuum cleaner . Sellers can enter as local stores , websites etc . Thus the price of cleaner falls until the price reachers where it is equal to marginal cost at minimum point of Average Total Cost ( ATC ) . So each seller earns zero economic profit in long run just as in perfect competition . Opposite happens if firms are facing loss in short run .
