Consequently, the societally optimal firm size is OQ 2, where long-run average cost is at its lowest level. The socially optimal firm size is the size for a company in a given industry at a given time which results in the lowest production costs per unit of output.
Second, Pigouvian taxes do not work in the long-term because the number of firms can vary. Third, an industry with a specific number of firms and scale can achieve the long-run social optimum (LRSO). The best option is to add an entry tax for potential firms and a subsidy for current firms to restrict a movement in the number of firms.

For instance, if the minimum efficient scale is small relative to the overall size of the market (demand for the good), there will be a large number of firms. The firms in this market will be likely to behave in a perfectly competitive manner due to the large number of competitors. [ 4 ]
The loss in both surplus' are deemed allocatively inefficient and not socially optimal. In contrast, when the firm has more information and discrimination is present, monopoly pricing becomes increasingly efficient as it approaches perfect discrimination through the various forms of price discrimination: Quantity Discount; Market Segregation
If the firm is a perfect competitor in all input markets, and thus the per-unit prices of all its inputs are unaffected by how much of the inputs the firm purchases, then it can be shown that at a particular level of output, the firm has economies of scale (i.e., is operating in a downward sloping region of the long-run average cost curve) if ...
In both scenarios, dollar-cost averaging provides better outcomes: At $60 per share. Dollar-cost averaging delivers a $6,900 gain, compared to a $2,400 gain with the lump sum approach.
Perfect competition leads to firms producing the socially optimal output level at the minimum possible cost per unit. Firms in perfect competition are "price takers" (they do not have enough market power to profitably increase the price of their goods or services).
