5.hy does the vertical gap between the firm’s D curve and MR curve get larger as the firm sells W more output? This is because the loss in total revenue from the first units resulting from lowering the price to sell one more unit gets larger as the firm’s total output increases.
Why is the MR curve below the demand curve?
Because the monopoly faces the downward sloping market demand curve, it must reduce its price to sell more output, which means price will be greater than marginal revenue (MR). We add the firm’s MR curve below its demand curve in Figure 3-12.2, as well as the monopolist’s MC curve.
What happens when the firm’s demand curve shifts to the right?
Even when the firm’s demand increases, i.e., its demand curve shifts to the right and/or its MC curve shifts upwards, it is not impossible for it to achieve profit maximisation at the prevailing price.
Why is the marginal revenue curve twice as steep as the Q?
Notice also that, because the marginal revenue curve is twice as steep, it intersects the Q axis at a quantity that is half as large as the Q-axis intercept on the demand curve (20 versus 40 in this example).
Why is the MR curve of oligopolistic firms kinked?
We have seen that, because of these reactions, the demand curve of each oligopolistic firm will be kinked, and the MR curve of this demand curve will have two separate segments, and there will be a vertical gap between them.
Why will a firm maximize its profits or minimize its losses at the output where MR equals MC?
The firm will maximize profit or minimize loss as long as producing is better than shutting down. Because, for purely competitive firms, marginal revenue = price, maximum revenue is also earned when the marginal cost of producing the last unit equals the market price.
When a competitive firm doubles the amount it sells what happens to the price of its output and its total revenue?
1. When a competitive firm doubles the amount it sells, the price remains the same, so its total revenue doubles.
What is the relationship between marginal revenue and price elasticity?
Just as there is a relationship between the firm's demand curve and the price elasticity of demand, there is a relationship between its marginal revenue curve and elasticity. Where marginal revenue is positive, demand is price elastic. Where marginal revenue is negative, demand is price inelastic.
How does the marginal revenue of a perfectly competitive firm relate to output?
While marginal revenue can remain constant over a certain level of output, it follows from the law of diminishing returns and will eventually slow down as the output level increases. In economic theory, perfectly competitive firms continue producing output until marginal revenue equals marginal cost.
What happens to the value of a firm's additional output sold when the firm has some market power?
What happens to the value of a firm's additional output sold when the firm has some market power? The value of that additional output sold is its marginal profit.
Why does profit maximization occur at Mr MC?
Maximum profit is the level of output where MC equals MR. When the production level reaches a point that cost of producing an additional unit of output (MC) exceeds the revenue from the unit of output (MR), producing the additional unit of output reduces profit. Thus, the firm will not produce that unit.
What is the relationship between the marginal revenue curve and the demand curve for a single price monopolist?
The marginal revenue curve for a single priced monopolist will always be twice as steep as the demand curve. Since the demand curve reflects the price and the marginal revenue curve is below the demand curve, the price is no longer equal to the marginal revenue as it was in pure competition.
How does the marginal revenue received by a seller depend on the price elasticity of demand?
Marginal revenue is related to the price elasticity of demand — the responsiveness of quantity demanded to a change in price. When marginal revenue is positive, demand is elastic; and when marginal revenue is negative, demand is inelastic.
What is the relationship between Mr curve and demand curve in a monopoly market?
A monopolist's marginal revenue curve is always less than its demand curve.
How does the firm's marginal revenue MR compare to its marginal cost MC when it increases its output from 150 units to 151 units?
How does the firm's marginal revenue (MR) compare to its marginal cost (MC) when it increases its output from 150 units to 151 units? MR exceeds MC by $7.95.
When a firm's marginal revenues are higher than its marginal cost?
The marginal revenue is greater than marginal cost, the firm should increase its output. 2. If marginal cost is greater than marginal revenue, the firm should decrease its output.
Why a firm's marginal cost curve overlaps its supply curve in perfect competition?
Only Perfect Competition The marginal cost curve is a supply curve only because a perfectly competitive firm equates price with marginal cost. This happens only because price is equal to marginal revenue for a perfectly competitive firm.
Why is the demand curve important?
The demand curve is important in understanding marginal revenue because it shows how much a producer has to lower his price to sell one more of an item.
What is marginal revenue?
Marginal revenue is the additional revenue that a producer receives from selling one more unit of the good that he produces. Because profit maximization happens at the quantity where marginal revenue equals marginal cost, it's important not only to understand how to calculate marginal revenue but also how to represent it graphically: 01. of 07.
Is marginal revenue the same as demand curve?
In this case, marginal revenue is equal to price as opposed to being strictly less than price and, as a result, the marginal revenue curve is the same as the demand curve.
When producers have market power and sell a good or service that cannot be resold, the possibility of price
When producers have market power and sell a good or service that cannot be resold, the possibility of price discrimination arises. Price discrimination exists when a producer charges different prices to different customers for the same item, for reasons other than differences in cost. The seller needs to be able to divide the total market for the good into separate submarkets, each with a different demand for the good. There also must be no possibility of resale of the product between the submarkets; otherwise the different submarkets will collapse into a single market.
How does a monopolistically competitive market work?
If firms in a monopolistically competitive market are earning positive economic profits, other firms have an incentive to enter this market. As they do so, each firm’s share of the total market demand gets smaller and smaller. This means the demand curve facing a monopolistically competitive firm shifts to the left. This process continues until all firms remaining in the industry break even. Outside firms then will no longer have an incentive to enter the market, and existing firms will have no reason to leave because they are receiving their normal profit. Figure 3-16.2 shows the demand and average total cost curves for a typical firm in the monopolistically competitive market for sport shirts.
What is the opposite of perfect competition?
At the opposite end of the market spectrum from perfect competition is monopoly. A monopoly exists when only one firm sells the good or service. This means the monopolist faces the market demand curve since it has no competition from other firms. If the monopolist wants to sell more of its product, it will have to lower its price. As a result, the price (P) at which an extra unit of output (Q) is sold will be greater than the marginal revenue (MR) from that unit.
What is perfect price discrimination?
Perfect price discrimination is a monopolist’s dream because it means that the firm can charge each individual consumer the highest price that he or she is willing to pay for the firm’s product. As we will see in this activity, perfect price discrimination eliminates all consumer surplus and increases the monopolist’s total profit above what it would if the firm sold all output at one price. For the questions in this section, assume that Pat’s average total cost and marginal cost are constant and equal to $8 (ATC = MC = $8).

Table 1: Pure Competition
Unlike under perfect competition, a firm under imperfect competition such as under monopoly can sell more only by lowering its price. Therefore, the average revenue curve is downward sloping and its corresponding marginal revenue curve lies below it.
Table 2: Monopoly
When AR and MR are straight lines, sloping downwards, the marginal revenue falls twice as much as the fall in the average revenue. In other words, the marginal revenue will cut any line perpendicular to the y – axis at halfway to the average revenue curve. This can be proved mathematically. In figure 3, AB = BC.
