Examples are automobile companies likes Toyota, Honda and Mercedes-Benz.

They produce products that are differentiated.
Examples - Telecommunications]]> 2020-07-17 00:11:54 UTC https://padlet.com/t0136/sec15/wish/656462757 Q1 https://padlet.com/t0136/sec15/wish/656463147 Oligopoly is a type of market structure where its similar to monopoly in terms of high barriers for firms to enter the market. It consists only of few firms in dominating the market in offering differentiated and undifferentiated products. Therefore, they have more control over price but not price maker as they have to bench mark each other. In terms of demand curve, they have a downward-sloping and kinked demand curve which signifies demand above its current price is more elastic where demand below its current price is inelastic. Examples of oligopolies are automotive industry, petrol company as well as airlines.

For instance, cigarette, cereals, salt and so on.

Oligopoly is a market structure where a few firms dominate which none if them can keep the others from having significant influence. Example, smart phone
Q2
the demand curve of an oligopoly is called a kinked demand as the rivals will not change price if the firm raises its price until one point. this creates elasticity. however, as the firm reduces its price, rival will feel forced to lower theirs too so the firm will be less elastic.
Q3
Game theory is the study where people make decisions based on the action of others. It consists of rules that determine what actions are allowable, strategies that the individual do to attain their objective and payoffs that are the results of the interactions among individual's strategies
It applies in oligopoly since the actions of one oligopolist make large differences in the profits of another, which is different from perfect competition where they are price takers]]> 2020-07-17 00:16:30 UTC https://padlet.com/t0136/sec15/wish/656465679 Q2 https://padlet.com/t0136/sec15/wish/656472824 Kinked demand curve. The oligopolists face a demand curve that kinked at the current price and the demand curve become more elastic above the current price than below. If the oligopolist cut its price, its rivals will follow to prevent losing customer. If the oligopolist increases its price, the rivals will not follow to gain the customer. This also shows the interdependency between the oligopolists.]]> 2020-07-17 00:28:01 UTC https://padlet.com/t0136/sec15/wish/656472824 Question 2 https://padlet.com/t0136/sec15/wish/656473235 “Kinked” demand curve is the theory at which the oligopolist face a kinked demand curve at a current price. This is where the demand curve above the current price is elastic while the demand curve below the current price is inelastic. If the oligopolist cuts their price below the current price, the competitors will follow while the competitors will not follow if the oligopolist raise its price to above the current price.

Demand curve above the kinked point is elastic, and below is inelastic. Whenever a firm increases its price, the others will not follow because they will lose out a large number of customers. However, if the firm decreases its price, the other competitors would follow due to the fact that they will lose their customers to that particular firm since the demand curve below the kinked point is inelastic.]]> 2020-07-17 00:29:57 UTC https://padlet.com/t0136/sec15/wish/656474160 Q2 janicekwan1225 https://padlet.com/t0136/sec15/wish/656474339 The shape of demand curve for an oligopolist is ‘kinked’ because oligopolistic firms are strategic interdependence. The D curve is more elastic above the market price than below because one firm raise the price, others will not follow suit. However, when the firm cuts its price, others will cut the price also to prevent customers lost.Thus, price might set at the inflection point of the curve.]]> 2020-07-17 00:30:15 UTC https://padlet.com/t0136/sec15/wish/656474339 Q2 https://padlet.com/t0136/sec15/wish/656474831 The kinked D demand curve shows oligopolists face a D curve that is kinked at the current price. D being significantly more elastic above the current price than below. It happens because when a firm is cutting its price, its competitors will forced to lower their price whereas when a firm increases its price , its competitors will not follow the price increase]]> 2020-07-17 00:31:02 UTC https://padlet.com/t0136/sec15/wish/656474831 Q2 https://padlet.com/t0136/sec15/wish/656477468 This shape of an Oligopolist’s demand curve, is known as the Kinked Demand Curve.
 
The kinked demand curve is a theory where:
Oligopolists face a Demand curve that is kinked at the current price:
 
Where Demand is more ELASTIC above the current price, than below which is more INELASTIC
 
This is because if an Oligopolists decides to CUT ITS PRICE, its rivals will follow suit to prevent losing customers as well to the first firm, therefore being Inelastic since basically all firms have decided to reduce their price as well.
 
As for if Oligpolists decides to RAISE ITS PRICE, its rivals will not follow suit in an effort to gain customers from the first firm by charging lower prices than them, therefore the first firm will have an elastic demand curve.
 
This is also shows the Interdependency between the Oligpolists since the actions of one firm, being the firm that raises or decreases its price in this case, will affect the profits and actions of other Oligopolists within the market.

This can only be applied in oligopolist as there are only small number of large firms in the market which results in strategy interdependency simply means action of one will affect the profits of another. They have the dominance in the market where more or less they have control over price of goods. However, in perfect competitive markets, firms are price taker indicating they have no control over price and have to accept whatever price is given due to demand is perfectly elastic. Perfectly elastic demand could be linked to the fact of perfect substitutes are available since no barriers to enter such perfect competitive market. ]]> 2020-07-17 00:50:49 UTC https://padlet.com/t0136/sec15/wish/656487951 Q3 https://padlet.com/t0136/sec15/wish/656488093 Game theory is the study of the decisions of firms in industries where the profits of a firm depend on its interactions with other firms.
It is only essential to oligopolies but not to perfectly competitive market because oligopolies has the market power to charge different prices to its goods while firms in perfectly competitive market are only price takers.

It is essential to oligopolies due to the interdependency between the oligopolies in the market. Besides, oligopolies have the market power and able to charge different price to its good. However, firms in perfectly competitive market only price taker and unable to influence the price for the market. ]]> 2020-07-17 00:52:01 UTC https://padlet.com/t0136/sec15/wish/656488779 Q3 janicekwan1225 https://padlet.com/t0136/sec15/wish/656491985 Game theory is the study of the decisions firms made in industry where the profits of a firm rely on its interactions with other firms.
Because in an oligopolistic market, firms are strategic interdependence and they have relatively large market power to control price. Also, there are closed but not perfect substitutes in this market so firms will need to interact with others and keep track on the price set by its competitors and make adjustment on price in order to prevent loss of consumers. In a perfectly competitive market, products are identical, and firms are price takers, so it is unnecessary to play the ‘game’ since their market power is small. and price is fixed.

It is essential to oligopolies because they have high market power to control the prices. This means that firms in perfectly competitive market are not able to do this due to their low barriers to entry and the number of competitors available.]]> 2020-07-17 01:03:04 UTC https://padlet.com/t0136/sec15/wish/656495982 Q5 https://padlet.com/t0136/sec15/wish/656512234 Collusive oligopoly refers to oligopolist cooperate with one another in setting price by not undercutting each other. This will results in both oligopolies gaining maximum profit.
