A monopolistically competitive firm will maximize profits by producing the output at which

marginal revenue equals marginal cost.

Identify the market structure that most accurately describes the context in which each good or service is sold: retail clothing

monopolistic competition The retail clothing market is an example of monopolistic competition. In this market, there are many competitors selling similar but differentiated products. For example, many of the firms in this market sell T-shirts that are similar but differentiated by different styles or colors. There are also few barriers to entry into this market.

monopoly

Identify the market structure that most accurately describes the context in which each good or service is sold: locally regulates sewage disposal

monopoly Local sewage disposal and intercity rail services in the United States are examples of monopolies. Sewage services are typically provided exclusively by local cities or municipalities, and Amtrak, a government-owned corporation, has a monopoly on intercity rail services in the United States.

Identify the market structure that most accurately describes the context in which each good or service is sold. automobile indsutry

oligopoly

Identify the market structure that most accurately describes the context in which each good or service is sold: commercial airline manufacturing

oligopoly The commercial airline manufacturing and automobile industries are examples of oligopolistic markets. There are few firms in both markets, and these firms sell similar but differentiated products. There are also significant barriers to entry in these industries, such as high start-up costs.

Please classify the source of barriers to entry described in each scenario below. d. Caribbean Cruz owns the only swimmable beach on an exclusive island in the Bahamas.

Monopolies and monopolistically competitive firms differ in that monopolies

participate in markets where barriers to entry are present.

Identify the market structure that most accurately describes the context in which each good or service is sold: high quality russet potatoes

perfect competition The market for russet potatoes is a perfectly competitive market. In this market, there are identical products and no barriers to entry. Examples of perfect competition are rare in real life since even agricultural products like potatoes could be distinguished by their quality or by whether they are organic.

Characterize three properties of the market structure: monopoly

positive long run profits efficient quantity not produced barriers to entry

Characterize three properties of the market structure:: duopoly with collusion

positive long run profits efficient quantity not produced barriers to entry

In long-run perfectly competitive equilibrium, marginal revenue, which is the _____, also intersects the ____ and ___ curves at the equilibrium point.

price atc mc

total revenue =

price x quantity

Monopolistic competition is achieved through product differentiation, but having monopolistic competition does not mean that :

productive and allocative efficiency is achieved. [It is possible to have waste and not have productive efficiency through the duplication of products. Furthermore, it is possible to not have allocative efficiency since productive efficiency is not achieved. Recall that allocative efficiency is one of the productive efficient points, which is going to be optimal for society.]

In the long run, a perfectly competitive firm will produce at

the minimum point on the ATC;

What is the most likely price agreed upon by the cartel?

the obvious point where it kinks

Which of the following are characteristics of a monopoly market structure? there are low barriers to entry into the market. there is only one firm in the industry. no close substitutes are available. firm(s) have little to no price-setting power

there is only one firm in the industry. no close substitutes are available.

In the short run, firms in the market make a profit because: As a consequence, firms will enter the market as long as:

they produce where marginal revenue equals marginal cost, and at this point, the average cost is lower than the demand. profits are being made

For a monopoly, a. At what quantity should a firm produce? b. Following this choice in quantity, what should the firm choose next? c. In order to assess whether profits or losses have been accrued, what should happen next?

where MR = MC They should choose the price that correlates with the chosen quantity on the demand schedule. Compare price to average total cost at the quantity produced.

is a patent a barrier to entry?

yes

is exclusive ownership of a resource a barrier to entry?

yes

is mass production a barrier to entry?

yes

Characterize three properties of the market structure: monopolistic competition

Suppose you are a manager of a firm that operates in a duopoly. Recently, the state attorney general fined you and your competitor for price fixing. In your market, firms only set prices, not total quantities to sell. From previous experience, you know your competitor has a marginal cost of $4.904.90. Further, your marginal costs are $4.884.88. The previous cartel price was $10.00, when you and your competitor were price fixing. What price level do you now choose to maximize profits?

$4.89

Profit =

(P - ATC) x Q

Given an equilibrium level of output in an oligopoly market, each firm may face a kinked demand curve because the firms

agree to cut prices if another firm cuts prices.

total cost =

ATC x quanitty

explain where a loss is on the graph

Because ATC is higher than price, the point on ATC will be the upper‑right corner of the loss box. The lower‑right corner is the monopoly's loss-minimizing price and quanitity

explain the steps of finding the profit maximizing quantity

Finding the profit maximizing quantity and price is a two-step process. First, find the point where marginal cost (MC) equals marginal revenue (MR). The quantity at this point is the profit maximizing quantity. Second, find the maximum price the monopoly can charge for each unit by locating the point on the demand schedule associated with the profit maximizing quantity. This price is the maximum per unit price demanders are willing and able to pay for the profit maximizing quantity

The perceived demand curve for this oligopolistic firm in a cartel appears kinked because

all firms will match price decreases but not price increases.

what happens if the ATC curve is BELOW or ABOVE the demand curve at the profit-maximizing quantity?

If the ATC curve is below the demand curve at the profit-maximizing quantity (which implies ATC is less than price at the profit-maximizing quantity), then the profit calculation will be positive. If the ATC curve is above the demand curve at the profit-maximizing quantity (which implies ATC is greater than price at the profit-maximizing quantity), then the profit calculation will be negative. This means the firm generated losses.

How can a kinked demand curve indicate that the firms in the oligopoly will continue to behave as a cartel and not have an incentive to deviate from the cartel?

If the firms in the oligopoly collude to restrict output, the firms implicitly agree to cut prices if a firm in the oligopoly cuts prices.

To correctly assess whether profits or losses are generated, first think about how profits are calculated:

Profit=(𝑃 - 𝐴𝑇𝐶)×𝑞 According to this equation, the monopoly will earn a profit if and only if the ATC is less than the per unit price

where does a monoploy maximize profits?

The firm maximizes profits at the quantity where marginal revenue (MR) equals marginal cost (MC). Find the point where MR and MC cross. When you look straight down to the horizontal axis, you will see the quantity the firm will produce. Although it is tempting to look straight over to the left of this intersection to find price, that is not accurate. From the point where MR equals MC, look straight up to the demand curve and then across to the left to find the price consumers are willing to pay for the profit‑maximizing quantity

what are the 4 characteristics of product differentation?

These characteristics include some physical aspects such as the packaging, location where the product is sold such as at a high end retail store versus a discount department store, some intangible aspects such as money‑back guarantee or free delivery, or the customer perception of the product, which can be affected through advertising.
