If SS were the industry supply schedule in diagram the level of industry output would be OK units and the market price would be PK Comparing this result with the actual industry price and output in equilibrium, we can conclude that the private market for textile leads to too large production of textiles (by KM = OM-OK) units and too low a price (Pi instead of PK). In most context, the marginal cost schedule of a firm represents all the additions costs incurred to produce a given unit of output.
