Step-by-Step Solution:
Step 1 of 3

Four Market Models - Pure competition - entails a large number of ﬁrms, standardized product, and easy entrance by new ﬁrms - At the opposite extreme, pure monopoly has one ﬁrm that is the sole seller of a product or service with no close substitutes; entry us blocked for other ﬁrms - Monopolistic competition - is close to pure competition, except that the product is differentiated among sellers rather than standardized product - An oligopoly is an industry in which only a few ﬁrm exist, so each is affected by the price Pure Competition: Characteristics and Occurrence - The characteristics of pure competition: • Pure competition is rare in the real world, but model is important - Model helps analyze industries with characteristics similar to pure competition - Model provides a context in which to apply revenue and cost concepts developed in previous chapters - Pure competition provides a norm against which to compare and evaluate the efﬁciency of real world • Many seller means that there are enough so that a single seller has no impact on price by its decisions alone • The products in a purely competitive market are homogeneous/standardized, each seller’s product is identical to its competitor’s • Individual ﬁrms must accept the market price; they are takers and exert no inﬂuence over price - There are four major objectives to analyzing pure competition • To examine demand from the seller’s P.O.V. • See how a competitive producer responds to market price in the short run Explore nature of long run adjustments in a competitive market • • Evaluation efﬁciency of competitive industries Demand as Seen by a Purely Competitive Seller - Individual ﬁrm will view its demand as perfectly elastic • Demand sure isn’t perfectly elastic for the industry: only appears that way for individual ﬁrm Average, Total, and Marginal Revenue - Average Revenue- price per unit for each ﬁrm in pure competition - Total revenue- Price x quantity sold - Marginal Revenue - change in total revenue and will also equal unite prince in conditions of pure competition Proﬁt Maximization in Short Run: Two Approaches - In the short run a ﬁrm has ﬁxed plant and maximizes proﬁts or minimizes losses by adjusting output; proﬁt=TC-TR - Three Questions that must be answered • Should ﬁrm produce • If so, how much • What will be the proﬁt/loss - Firm shit down if the losses are greater than the ﬁxed cost - MR=MC rule means that the ﬁrm will maximize proﬁts/minimize losses by producing at a point which MR=MC in the Short Run Three features of this MR=MC rule are important • - Tule assumes that MR is less than or equal to the minimum average variable cost or ﬁrm will shut down - Rule works for ﬁrms in any type of industry - Price=MR - Determining equilibrium price for a ﬁrm and an industry • Total-supply and total-demand data must be compared to ﬁnd the most proﬁtable price and output levels Firms Vs. Industries - Firm vs. industry: individual ﬁrms must take price as given, but the supply plans of all competitive producers as a group are a major determinant of product price
