1. draw a diagram to show the long run equilibrium condition of the perfectly competitive firm
2. explain three reasons why monopolies arise
a) The below diagram shows the equilibrium in the long run in a perfectly competitive market. In the long run, the firm will only be breaking even i.e. no profit and no loss. The production will occur at the lowest point of the LAC (Long run average cost) and at this point, the LMC (Long run marginal cost) and Average revenue will be equal to marginal revenue and price.
