SHUTDOWN RULE, MONOPOLY: The marginal revenue and marginal cost approach to analyzing a monopoly firm's short-run production decision can be used to identify circumstances in which a firm minimizes losses by shutting down production in the short run. If the market price falls below average total cost, it must decide if the economic loss from producing the quantity of output that equates marginal revenue and marginal cost is more or less than the economic loss incurred with shutting down production in the short run (which is equal to total fixed cost).

HHI: The common abbreviation for the Herfindahl-Hirshman index (or the Herfindahl index), which is a measure of concentration of the production in an industry that's calculated as the sum of the squares of market shares for each firm. This is an alternative method of summarizing the degree to which an industry is oligopolistic and the relative concentration of market power held by the largest firms in the industry. The Herfindahl index gives a better indication of the relative market control of the largest firms than can be found with the four-firm and eight-firm concentration ratios.
