The deep state entered Americaâs national discourse in 2017 with the feeling of an already familiar character, ready to assume a starring role as hero or villainâdepending on how you feel about Trump.
If a firm produces past that point, then marginal revenue is less than marginal cost. This means that the firm is losing profit with each additional unit of output and it should produce less. Remember that a competitive firm has a flat MR curve which is equal to the market price.
But perfectly competitive markets are not necessarily productively efficient as output will not always occur where marginal cost is equal to average cost (MC = AC). In perfect competition, any profit-maximizing producer faces a market price equal to its marginal cost (P = MC). This implies that a factor's price equals the factor's marginal revenue product. It allows for derivation of the supply curve on which the neoclassical approach is based.
