Document Summary

People who operate firms make many decisions, and all of their decisions are aimed at achieving one goal: maximum attainable profit. Decisions about the quantity to produce and the price to charge depends on the type of market in which the firm operates. Perfect competition, monopolistic competition, oligopoly, monopoly all confront the firm with their own special problems. Decisions about how to produce a given output do not depend on the type of market in which the firm operates. All types of firms in all types of markets make similar decisions about how to produce. The action that a firm can take to influence the relationship between output and cost depends on how soon the firm wants to act. A firm that plans to change its output rate tomorrow has fewer options than one that plans to change its output rate six months from now.
