In economical context there are main four types of marketing structures available. Those are Perfect Competition, Monopolistic Competition, Oligopoly and Monopoly. In each type of marketing structure consist of different types of characteristics. Those characteristics of each market industries can state as follows.

2.2.1 Perfect Competition

According Layton, Robbinson and Tucker (2005, p. 174) perfect competition refers to a market structure characterised by (1) a large number of small firms, (2) a homogeneous product and (3) very easy entry into or exit from the market. Some of other charaecterstics of perfect competition includes;

Horizontal demand curve (firms act as a price takers)

Both the buyers abd sellers possess perfect knowledge about the markets.

No transport costs within the markets.

Perfect mobility of factors of production

(Industry market structures[Handout], n.d., p. 1)

Products are close substitutes to each other and they are branded (e.g. soap, liquor etc.).

If the price is increased, the firm will not lose all its customers.

If the price is decreased, the firm will not win all the customers who are with the competitors.

Firms often cut prices to increase its market share.

(Industry market structures[Handout], n.d., p. 2)

Firms will avoid price wars and concentrate on non-price strategies to win market share. They use strategies such as better product design and finish, improvement of quality, better packing, after sales services, effective distribution, advertising, promotions, guarantees etc.

3.0 Dominant Market Structure of the Company

After considering all aforesaid characteristics of industry market structures, it is identified that the Dialog is operate within Oligopoly Market Structure. This can justify from the following characteristics of oligopoly in related to Dialog.

3.1 Characteristics of the Oligopoly Market Structure in related to Dialog

There are many characteristics that distinguish the oligopoly market structure from other market structures; the behavior of firms in this market structure also differs significantly from other market structures. Those characteristics include,

3.1.1 Few sellers in the market

 According to the definitions of oligopoly it can be identified that this type of market structure is consist of few sellers and its usually ranging from 2-10. When considering the Sri Lankan mobile telecommunication industry, it is clearly can identify that there are only five service suppliers existed within the market. Following chart shows how the total revenue of the market divides among the five service suppliers.

Figure: 2

Source: Business International (2009) Concentration Ratio

According to Joseph,G. (2008,p.199) concentration ratio represent the extent of the market supplied by a given number of firms. For example when considering four concentration ratio, its shows the portion of market supply by the leading firm of the industry. When we apply this into Sri Lankan mobile telecommunication industry, it is clear that nearly 95% of market share split among main four suppliers of the market. (Dialog, Mobitel, Etisalat, Airtel) Four concentration ratio theory suggest that if the concentration ratio of major four firms of a single industry is greater than or equal to 40%; that market which the firms are operate in more likely to be a oligopoly market. Since 95% of total Sri Lankan mobile telecommunication supply operate by the major four suppliers, it can be prove the fact that the Dialog is operate within the oligopoly market.

3.1.2 Mutual interdependence of the firms

One main characteristic of an oligopolistic market structure is that the firms are interdependent. Each firm is affected by its rivals actions, thus if Dialog decides to pursue policies to increase sales, then it will be at the expense of the competitors. The rivals may then respond by taking action to increase their market share, therefore no firms can afford to ignore the actions of the rival firms. It is thus impossible to predict the implications on a firm due to a change in price without considering the reactions of the rivals.

3.1.3 Barriers to entry

The oligopoly market structure has high barriers to entry. Barriers to entry may include patent rights, laws and industry regulations, high capital investment and etc. The high sunk cost or the high initial capital investment is the major barrier to entry to the mobile telecommunications market. When considering Dialog, it’s operates within an oligopoly market structure where there is high barriers to enter into the market. All the firms operate within Sri Lankan mobile telecommunication industry should licenses granted under Section 17 of the Sri Lanka Telecommunications Act No 25 of 1991 as amend. (Telecommunication regulatory commission of Sri Lanka, 2010) This is a significant reason for firms in an oligopolistic market structure to earn normal profits.

3.1.4 Non-price competition

Firms in the oligopolistic market structure attempts to avoid price competition as price wars may arise. Thus “brands” are established, Dialog is a well establish brand in the mobile telecommunication market, which highlights a certain characteristic that create a competitive edge for the company. Dialog boasts about the island wide coverage they offer.

Non-price competition may be in the form of sales promotions, special packages or even better facilities or clarity would matter. Dialog GSM also sponsors many sports activities such as the rugby tournament. Innovation is another form of price competition; Dialog launched the first Sinhala/Tamil sms facility as well as 3.5 G facility in there service operations.

3.1.5 ‘L’ shaped average cost curves


Economic studies suggest that the average cost curves of large firms operating in an oligopolistic market structure is ‘L’ shaped rather than ‘U’ shaped. Reason for this is because large firms face the same average variable cost regardless of increase or decrease in output. (Anderton, 2006, pg.363)

3.1.6 Kinked demand curve

As mentioned above the demand curve of a normal firm is a downward sloping strait line. A firm in the oligopolistic market has a kinked demand curve; this theory was founded by Paul Sweezy from the USA and R. Hall and C.Hitch in the UK. (Anderton, 2006, pg.363)

Figure 4

Source: Alain Anderton – Economics 3rd edition 2006, pg. 364

The theory suggests that a firm in an oligopoly market, like Dialog must make an assumption of how one firm (Mobitel/Etisalat) might react to price changes in the market. The kinked demand curve model assumes that there will be an asymmetrical reaction to a change in price. Thus if Dialog increases its price, other firms will not react. On the other hand if Dialog reduces the price, then other firms will also reduce its price to prevent losing their market share.

In the diagram shown below the profit maximizing level is where the MC (marginal cost ) curve cuts the MR ( marginal revenue ). Thus if the MC of the firm lies anywhere between MC1 and MC2, the profit maximizing output will be P1 and Q1. Hence prices will remain stable even with considerable change in cost. (Sloman, 2004, Pg 208).

However the kinked demand curve model has two main limitations that must be noted. Although it shows price stability, it may be due to other reasons- Dialog may not want to revise prices frequently because it is inconvenient to establish new price list, new accounting policies, and it may upset it customers. Another drawback is that the model does not explain how the prices are being set in the first place. This is a serious drawback for a firm during periods of inflation, where Dialog like other firms in an oligopoly market will raise prices due to increase in cost and demand. This model suggests that the price will be raised only, when the marginal cost increases above MC2 which is illustrated in the diagram below.
