PROBLEM SET #6: PRODUCTION COSTS, PERFECT COMPETITION, MONOPOLY, PRICE DISCRIMINATION Notes: The US shirt industry is perfectly competitive and is in long-run equilibrium. There are 10 firms each with a total cost function of STC = 9+q2. The long run total costs are the same except that the fixed costs are not incurred if the firm does not produce. The number of firms is fixed in the short Equilibrium under monopolistic competition. In the short run supernormal profits are possible, but in the long run new firms are attracted into the industry, because of low barriers to entry, good knowledge and an opportunity to differentiate. Monopolistic competition in the short run. At profit maximisation, MC = MR, and output is Q and price P. Given that price (AR) is above ATC at Q

Long-run equilibrium of the firm under monopolistic competition. The firm still produces where marginal cost and marginal revenue are equal; however, the demand curve (and AR) has shifted as other firms entered the market and increased competition. The firm no longer sells its goods above average cost and can no longer claim an economic profit. In the short-run, the rm can also su er a loss, just like a monopoly Herriges (ISU) Ch. 16 Monopolistic Competition Fall 2010 12 / 18 Firm Behavior in a Monopolistically Competitive Industry Behavior in the Long Run

We will understand how to analyze shocks to these equilibria. DETERMINATION OF LONG RUN PRICE AND EQUILIBRIUM: DETERMINATION OF LONG RUN PRICE AND EQUILIBRIUM In the long run monopolist will be in equilibrium at a point where his long run marginal cost is equal to marginal revenue.

There are 10 firms each with a total cost function of STC = 9+q2. The long run total costs are the same except that the fixed costs are not incurred if the firm does not produce. The number of firms is fixed in the short Long-Run Equilibrium In the long run, a monopolistically competitive firm earns a normal (average) accounting, or zero economic profits. A firm looks at its cost of production and then marks up its price to obtain a reasonable profit.

Equilibrium under monopolistic competition. In the short run supernormal profits are possible, but in the long run new firms are attracted into the industry, because of low barriers to entry, good knowledge and an opportunity to differentiate. Monopolistic competition in the short run. At profit maximisation, MC = MR, and output is Q and price P. Given that price (AR) is above ATC at Q Short Run – Short-run economic profits encourage new firms to enter the market. This: The Long-Run Equilibrium • Two Characteristics • As in a monopoly, price exceeds marginal cost. • Profit maximization requires marginal revenue to equal marginal cost. • The downward-sloping demand curve makes marginal revenue less than price. • As in a competitive market, price equals average

24/01/2011 · a) Explain the difference between short-run equilibrium and long-run equilibrium in monopolistic competition. b) “Perfect competition is a more desirable market form than monopolistic competition.” Discuss. Figure 1 Equilibrium in perfect competition and monopoly The diagrams in Figure 1 show the long run equilibrium positions of the firm in perfect competition and the monopolist. We can clearly see that for the perfectly competitive firm, productive efficiency automatically arises as in long run equilibrium MC=AC at point X.

Long-run equilibrium of the firm under monopolistic competition. The firm still produces where marginal cost and marginal revenue are equal; however, the demand curve (and AR) has shifted as other firms entered the market and increased competition. The firm no longer sells its goods above average cost and can no longer claim an economic profit. Chapter 12 Monopolistic Competition and Oligopoly Suppose a monopolistically competitive firm is making a profit in the short run. What will happen to its demand curve in the long run? The flatness or steepness of the firm’s demand curve is a function of the elasticity of demand for the firm’s product. The elasticity of the firm’s demand curve is greater than the elasticity of market

Long-Run Equilibrium In the long run, a monopolistically competitive firm earns a normal (average) accounting, or zero economic profits. A firm looks at its cost of production and then marks up its price to obtain a reasonable profit. In the last video we saw that if we had a market with perfect competition, and if the current short-term equilibrium price is above the price the necessary or is above the price at which firms would be generating economic profit, then more and more firms would start entering.

the long-run, possibly to almost the same level as the initial level. As to output, we would As to output, we would expect it to go up, with a greater increase in the long-run than in the short run. A monopolist can make profit in the short and long run. It can also makes losses (see the next diagram), although the firm might pull out rather than keep making losses into the long run. It can also makes losses (see the next diagram), although the firm might pull out rather than keep making losses into the long run.

Short-run and Long-run Equilibrium (monopoly) In the long run there is no profit as the average cost equal the average revenue, as supernormal profits would attract more firms which would lower it. Do monopolist output have productive and allocative efficiency. not allocatively efficient, might be productively efficient. no AE efficient because Marginal benefit is greater than Marginal This means that the short run supernormal profit attracts new producers into the market, and so normal profits only are made in the long run equilibrium As more firms enter the market, the demand curve facing any existing firm moves to the left (as consumers choose the products offered by new or alternative companies).

Discuss short-run equilibrium in monopolistic competition. Use a graph to show long-run equilibrium in monopolistic competition. Distinguish between economic profit and normal profit .
