The diagram to the right depicts an industry that initially starts out with a single firm that enjoys a monopoly and the initial monopoly profit that comes with it. Later, a second firm enters into the industry, lowering its price to obtain customers that usually do not purchase the product at the high Monopoly Price . As the initial monopoly firm loses customers, it is forced to lower its price to retain profitability. In the competition for sales to customers, the firms lower their prices even further, which increases the consumer demand for the product, and thereby entices the firms to raise production and which then increases the industry's total production and sales. Finally, the price and production in the industry stabilizes into its "competitive equilibrium"; the price paid by the consumers are just high enough to cover the average economic cost of producing the product, and the available quantity of the product doubles from its initial sales (under the monopoly).
