Answer 7

One firm has 100% concentration ratio Unique product Imperfect knowledge High barriers to entry and exit Price maker

Answer 8

Productive efficiency Allocative efficiency Dynamic efficiency X-inefficiency

Answer 9

Occurs at the lowest cost per unit of output, of the lowest point of the average cost curve. The firm is producing as much as possible relative to inputs. It is where the marginal cost intersects the average cost.

Answer 10

Occurs when the cost of production and the demands of consumers are taken into account to maximise welfare. Firms will charge a price equal to the marginal cost (P = MC) of manufacturing the good. It is where the price charged for the last unit (the amount people are prepared to pay) is equal to the cost of making the last unit, so net welfare falls if any more united are produced. It is also called welfare maximisation.

Answer 11

Occurs at the lowest point on the average cost curve. This is where average cost is at its lowest.

Answer 12

Producing at a point where the price of a good is equal to the marginal cost of production

Answer 13

Looks at how changes in technology and productive techniques over time will increase the productive potential of a firm. This is very distinct from productive and allocative efficiencies which are assumed to be static.

Answer 14

Occurs when the average cost is higher than the lowest possible average cost: in other words, the firm operates above its AC curve. This can happen in highly concentrated markets, such as monopoly and oligopoly, wheee firms are able to make supernormal profits and have an AR that is greater than their AC, thus reducing the need or desire to lower AC and decrease x inefficiency.

Answer 15

Many small firms Homogeneous products (exactly the same) Perfect knowledge - this doesn’t mean the firm knows everything about rival firms price and output decisions. Rather, it means the firm has access to this information, including the latest technology and techniques and information on who makes supernormal profits. No barriers to entry or exit No price setting powers - perfectly competitive firms take the price set by the market. They are known as price takers.

Answer 16

A market where a large number of small firms co exist selling homogenous products. Normal profits are achieved in the long run because there are no barriers to entry to protect the market share of those firms that make supernormal profits in the short run.

Answer 17

The characteristics required for perfect competition suggest that there are few industries that approximate to the model of perfect competition. These include the market for foreign currency, where there are low barriers to entry, price takers (the price of currency sold is determined by the market), many small firms and homogenous goods (currencies are the same whoever sells them), and the market for agricultural goods such as carrots.

Answer 18

The firm is taking the industry or market determine price, P. This is above the firms average cost at the profit maximising output of MC = MR. Therefore, the firm is making supernormal profits. AR = MR = D is a horizontal line as price takers.

Answer 19

Because rival firms will see that these supernormal profits are being made (because of perfect knowledge) and enter the industry (no barriers to entry). The market supply curve will shift to the right and thus AR = MR curve will shift downwards and the price will fall, until all the supernormal profits are competed away and the firms make normal profits in the long run.

Answer 20

In the long run, a perfectly competitive firm will always make normal profits only, any supernormal profits having been competed away and the losses removed by firms leaving the industry. This is known as the long run equilibrium. The horizontal AR = MR curve equals MC equals AC.

Answer 21

Occurs when the firm is not covering average variable costs. It may be feasible for a firm to make a loss in the short run, as long as it covers the variable cost of making the good and therefore makes a contribution to the fixed costs. A firm will shut down if it cannot cover average variable cost.

Answer 22

These firms have many of the characteristics of firms operating under conditions of perfect competition except they are are able to set price to a limited extent because the products they produce are not exactly the same, customers have some loyalty in the market, and the demand curve is not perfectly price elastic. Examples include restaurants, hairdressers and nail bars. The firms are easy to set up, have some local loyalty from returning customers, but do not enjoy supernormal profits in the long run. They are closed down quickly if demand falls.

Answer 23

It’s the marginal cost curve above the average variable cost. In the long run, the average variable cost is the same as average total costs (there are no fixed costs) so the rule still holds.

Answer 24

Many small firms Similar goods, slightly differentiated possibly though, among other things, quality, branding or advertising. Imperfect knowledge about rival firms price and output decisions but firms will be able to identify when supernormal profits are being made. Low barriers to entry and exit Firms can set price to an extent because they are producing goods that are slightly different from those of rival firms.

Answer 25

A market with many small firms, which supply goods that are slightly differentiated, allowing them some price setting powers.

Answer 26

In the short run, a monopolistically competitive firm can make supernormal profits. As with all market structures apart from perfect competition, a monopolistically competitive firm need not operate at the productively efficient (ie lowest point On the average cost curve) or allocatively efficient (ie where p = MC) levels of output. AR and MR curves are separate with MR being steeper and closer to y axis. Supernormal profit area is where MC =MR drawn up to the AR curve and so including though the AC curve. The area is between the AR and AC curve.

Answer 27

As with perfect competition, a monopolistically competitive firm cannot maintain supernormal profits in the long run due to the near perfect knowledge that allows firms to identify the profits to be made, and the low barriers to entry that allow firms to enter the market and compete profits away. It is for these reasons that the long run position for a monopolistically competitive firm is described below: Check page 30 please. AC is above AR and MR and touches the AR curve at one point, directly below this, MR intercepts MC. Normal profits being made.

Answer 28

Imperfect competition

Answer 29

Because, as in perfect competition, there are very low barriers to exit, which means that should firms be making losses they will leave the industry rather than try to persevere in the long run. They are unlikely to have sufficient cash reserves to be able to justify the pursuit of long run profits as a motive.

Answer 30

Oligopoly exists where a few, interdependent firms dominate the market. Interdependence means that the actions of one firm in the industry will impact on the other firms in the industry: for example, if one firm were to lower its prices, this could force other firms to react in the same way, otherwise they would lose market share. This sort of market structure typically plays host to collusive behaviour among the main firms. Examples of oligopolies include the brewing industry, pharmaceuticals, food and confectionary manufacturers and petrol retailers.

Answer 31

A market dominated by a few large firms - often associated with interdependence and collusion

Answer 32

A few large firms dominate Goods with some similar characteristics but brand loyalty tends to be strong Imperfect knowledge about rival firms price and output decisions High barriers to entry and exit Oligopolies can set price but may decide to agree price fixing deals with rivals to avoid price competition

Answer 33

With only a few firms dominating an industry (I.e a high concentration ratio), firms will tend to avoid price competition. This happens because if one firm were to lower prices, others would follow, and although they might gain some additional sales, this would be at the cost of lost revenue from the price war that would ensue. Therefore an oligopoly is also characterised by non price competition.

Answer 34

Price wars are triggered when one firm in an oligopoly cuts price. Others tend to follow to avoid losing market share. This can lead to further price cuts.

Answer 35

Collusion can be defined as an agreement between two or more firms to limit competition and therefore divide the market, set prices or output, and increase the welfare gains of the firms concerned to the detriment of other firms and consumers. Most collusion is illegal due to its restrictive nature and its impact on firms and consumers.

Answer 36

Firms, often operating under oligopoly conditions, working together to fix prices and avoid price wars.

Answer 37

Overt collusion Tacit collusion

Answer 38

Where firms openly fix prices, output, marketing or the sharing out of customers. An extreme form of overt collusion is forming a cartel, which is a formal agreement between firms to act together, as in the case of the sugar cartel that operated in the USA between 1934 and 1974, but cartels are illegal in the EU And many other countries.

Answer 39

This is quiet or ‘behind the scenes’. This may be implicit co operation and involve no spoken agreement. The result of tacit collusion is the same as with overt collusion - the firms do not compete with each other or prices are higher than they would otherwise be: that is, there is price fixing. Tacit collusion may take the form of a collection of firms avoiding competition and following the actions of a market leader, known as a price leader. This type of collusion is also illegal in most countries and can result in firms being fined or executives being jailed for their actions.

Answer 40

Firms coming together to ensure that prices remain stable and therefore price competition is avoided.

Answer 41

Overt collusion is open - it is an agreement between firms to collaborate in some way to restrict competition. Tacit collusion Is quiet, unspoken or unwritten. It may be implied, or involve firms operating according to some pattern that has never been agreed but has come into effect.

Answer 42

These is always a temptation to break an agreement either to maximise a firms sales by lowering prices and catching a rival unaware or to gain immunity from prosecution by acting as a whistle blower and informing the competition authorities about any collusion agreement.

Answer 43

Let us assume that there are two firms, called Adrian and Juju, in an industry. It is clear that if Adrian and Juju collude, they will be able to make profits of £100 million each by setting prices at a high level. This collusion will result in the two firms collaborating to maximise their combined profits. However, they each know that they can increase their individual profits by lowering prices and breaking any collusive agreement, so obtaining £120 million while the other firm keeps higher prices as agreed and ends up with profits of only £50 million. This is known as the maximax strategy because it seeks to maximise the firms maximum payoff. As a result of neither firm trusting each other, they will therefore both adopt the low price strategy, trying to do so before the other does, and they will end up with £80 million, which is a worse outcome than if they had colluded and set a high price, but better than if they had continued to pursue a high price strategy while the other firm lowered its prices. This suggests that due to a lack of trust between firms, any collusive agreement is likely to be broken. This is referred to as the maximin strategy because it maximises the firms minimum pay off.

Answer 44

Include the prisoners dilemma, which can be used to explain the reaction of two prisoners lacking trust and pursuing their own self interest in the same way as we consider the reaction of two firms. Game theory can be used to illustrate the behaviour of oligopolies.

Answer 45

You don’t need to know the analysis but may be helpful. It can illustrate the behaviour of oligopolies. It shows the price rigidity that exists in many markets and the asymmetric reaction by other firms when one firm raises or lowers its price. It also suggests that firms will not break any collusive agreement as they can see that the outcome will be a price war that is of no benefit to either party.

Answer 46

Please check diagram, basically it’s like a line bent so the left half has a low gradient and at a point it switches to a steeper gradient. Please just check diagram idrk

Answer 47

It illustrates why firms will tend to fix prices at a certain level. If a firm raises prices on more horizontal part of line, it will be operating on the price elastic part of the demand curve. This is because other firms will not respond and consumers will switch away from the firm raising its price. However, if the firm decided to lower the price from the break point to the more vertical part of the curve, other firms in the market would follow suit and a price war would ensue, meaning that none of the firms would gain a significant increase in their market share. Therefore the demand for the good is relatively price inelastic in relation to a price fall. This suggests that the firm is best keeping its prices at the break point, because either raising or lowering prices leads to a fall in revenue. This can be used to explain sticky prices - the observation that many shops charge the same amount for some things as their competitors and prices do not change much over time. It might look like collusion, but here is a reason to argue that it is not.

Answer 48

Use the kinked demand curve to show that what might look like collusion or a cartel is instead of ‘sticky price’. It is useful evaluation for showing that something that looks like tacit collusion is in fact legal, rational behaviour by interdependent firms.

Answer 49

A monopoly is the sole supplier of a good or service. The firm is able to set prices and output and to maximise profits. It is known as a price maker.

Answer 50

Single seller, with high barriers to entry

Answer 51

One firm Unique product Imperfect knowledge, potential rival firms will not know the incumbent firms pricing and output strategy High barriers to entry and exit Price maker

Answer 52

As a result of high barriers to entry, monopolists can set high prices to maximise profits without fear that another firm could enter the industry. It is for this reason that many governments will intervene to prevent the development of monopolies and ensure that competition is maintained in some form. Monopolies are also often accused of being x-inefficient. This refers to their tendency to allow costs to rise when there is no threat of a more efficient firm undercutting prices, and their being less inclined to innovate and develop new products because they have no need to maintain an edge over competitors. They may make supernormal profits at the expense of consumer surplus and are neither productively nor allocatively efficient. The diagram is just that of supernormal profit.

Answer 53

Monopoly no | Perfect comp yes

Answer 54

Monopoly: no | Perfect comp: yes

Answer 55

Monopoly: prices are higher under monopoly compared with perfect competition Perfect comp: prices are lower under perfect competition compared with monopoly

Answer 56

Quantity is lower under monopoly compared with perfect competition Quality is higher under perfect competition compared with monopoly

Answer 57

Less incentive to be efficient and to develop new products The existence of resources to protect market dominance by raising barriers to entry and preventing new competition- this will allow the monopolist to exploit its position by allowing it to exert pressure on any suppliers that might rely on it.

Answer 58

Supernormal profit means: finance for investment to maintain competitive edge Firms can create reserves to overcome short term difficulties, giving stability to employment Funds for research and development

Answer 59

Higher prices and lower output for domestic consumers Monopolies may waste resources by undertaking cross-subsidisation, using profits from one sector to finance losses in another sector and employing more labour. Monopolists may undertake price discrimination to raise producer surplus and reduce consumer surplus. Monopolists do not produce at the most productively efficient point of output (ie at the lowest point of the average cost curve) Monopolists can be complacent and develop inefficiencies Monopolies may lead to a misallocation of resources by setting prices above marginal cost, so that price is above the opportunity cost of providing the good, ie price is not equal to marginal cost.

Answer 60

Firms will have the financial power to match large overseas competitors Cross-subsidisation may lead to an increased range of goods or services available to the consumer: for example, the provision of services that are loss making but provide an external benefit, eg rural bus services. Price discrimination may raise the firms total revenue to a point that allows the survival of a product or service. Monopolists may be able to take advantage of economies of scale, which means that average costs may be lower than those of a competitive firm at its most efficient position. This is especially the case when there is a natural monopoly. There are a few permanent monopolies and the supernormal profit opportunities act as an incentive for rival firms to break down the monopoly through a process of creative destruction, I.e breaking the monopoly by product development and innovation and therefore bypassing any barriers to entry. Monopolists can avoid undesirable duplication of services.

Answer 61

Occurs when a firm sells the same product in different markets with differing elasticities at different prices. This is used by a firm with monopoly power to increase profits and to reduce consumer surplus and is possible because of high barriers to entry and exit.

Answer 62

The sale of the same good to two different markets at different prices. To do this a firm must be a monopolist able to identify two different groups and keep them separate.

Answer 63

There are high barriers to entry and a degree of monopoly power There are at least two separate markets with differing price elasticities of demand The markets can be kept separate at a cost that is lower than the gain in profits. This is to prevent resale (arbitrage) between the markets.

Answer 64

In practice you are unlikely to see perfect price discrimination and the model you will be required to use is third degree price discrimination.

Answer 65

Here firms can use different prices based on regional, consumer age or time of use differences. Examples of this type of price discrimination include the sale of child and adult railway tickets and the sale of peak and off peak telephone, electricity and gas services. Lunchtime menus, airline tickets and retail outlets often demonstrate this.

Answer 66

The firm splits the market into relatively elastic and relatively inelastic demand, selling the output at different prices to the markets and keeping these separate. In this example we assume that the firm faces constant average and marginal costs and has managed to identify two separate markets with differing elasticities. When the firm maximises profit in each market, it is able to make more supernormal profits than if the markets remained as one. Check the diagrams please

Answer 67

This is also correct and can be used to show either the total additional profit by adding together the elastic and inelastic markets, or the position before the market was split, allowing the student to show where the horizontal average and marginal costs have come from.

Answer 68

A natural monopoly exists when an industry can only support one firm. This is typical of an industry that has high sunk costs and requires large levels of output to exploit economies of scale.

Answer 69

Costs that a firm cannot recover on exit, such as advertising.

Answer 70

The introduction of competition, perhaps by some government agency, will not be possible in the long run, as neither of the competing firms would be able to obtain sufficient market share to ensure that it was able to exploit economies of scale. Any new firm would experience both significant start up costs, establishing the necessary infrastructure, and long run losses as it tried to compete with the existing suppliers.

Answer 71

Natural monopolies exist in the supply of water, gas, the rail income and electricity, where there are high start up and infrastructure costs. The costs of establishing a competing firm will outweigh any economic or social benefit that might materialise. Should the market be opened to competition and both firms take an equal share of the market, they will each make a loss. If one of the firms gained a greater market share then it might be able to survive, but this would be at the expense of the other firm, which would eventually fail, returning the industry to a monopoly situation.

Answer 72

Where there is a sole buyer of a good. For example, the government is the sole buyer of defence equipment in the UK. Government can use this power to extract the best price for itself, often by reducing the producer surplus the selling firm receives. Firms can use these powers to exploit their suppliers and drive down prices.

Answer 73

Monopsony power exists when sellers face powerful buyers. For example, if an individual wishes to work in emergency healthcare in the uk, then the sole buyer of such employees is the national health service. A number of firms could act together (collude) to increase buying power. In the supermarket industry, for example, the major retailers may join together to exploit their suppliers and ensure that the supermarkets are able to get the best possible price for their goods. A farmer faced with the choice of selling everything produced to the supermarket, or selling goods in the open market, usually opts to sell to the supermarket even if it is at a heavily discounted rate.

Answer 74

This sort of power may allow a firm to exploit its suppliers in the knowledge that the supplier has few options beyond selling to the sole buyer. This can mean that cheaper prices are passed on to the consumer, but only at the expense of the supplier of goods.

Answer 75

Buying power, not selling power.

Answer 76

Lower prices are passed on to consumers, and quality might be better than if there was perfect competition in buying resources. Monopsony power might balance out monopoly power. For example, some ‘DOC’ wine producing regions use their monopoly power to charge a high price, but supermarkets (monopsonists) can force them to supply at lower prices in order to make a high volume of sales.
