Term loss minimization rule Definition: A rule stating that firm minimizes economic loss by producing output in the short run that equates marginal revenue and marginal cost if price is less than average total cost but greater than average variable cost. In the short run, a firm incurs total fixed cost whether or not it produces any output. As such, if the market price is 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).
