Complete breakdown of Monopolistic Competition – Long-Run Equilibrium (Normal Profit) diagram for IB Economics, including detailed breakdown of the curves, and sample exam-style questions.
Definition: Monopolistic competition is a market structure which combines elements of monopoly and competitive markets. Essentially a monopolistic competitive market is one with freedom of entry and exit, but firms ca...
Under perfect competition, long run equilibrium is achieved at that point where MC = MR = AR = AC. Because of the perfectly elastic AR curve, a tangency occurs between AR and AC at the latter’s lowest point.
Hence, the long-run equilibrium for monopolistic competition exists when market price = average total cost, where marginal revenue = marginal cost, as shown in the diagram below. Remember, in economics, the average to...
monopolistic competition explained to make sure you're ready for your next AP, IB, or College Microeconomics Exam. Learn the qualities of monopolistically competitive markets, how to draw the graph, and more.
The entry of other firms into the same general market shifts the demand curve faced by a monopolistically competitive firm. As more firms enter the market, the quantity demanded at a given price for any particular fir...
As seen in Fig. 1 below, under monopolistic competition, firms’ demand curves fall into a price range with the least slope: You might find this explanation a little complicated. So let’s take a quick look at the most ...
Figure 2 shows the long-run equilibrium picture for monopolistic competition. Comparing monopolistic competition to perfect competition and monopoly, we see that there are sim-ilarities with both markets. As with mono...
In the short run, the graph looks like just like the graph for a monopoly, with the firm making an economic profit. In the long run, however, firms will enter the industry and cause the demand curve to shift to the le...
The long run sees free entry and exit, leading to zero economic profit. Both scenarios involve excess capacity and a markup over marginal cost, reflecting the balance between market power and competition.
