    Elective 1

    12. Mobile phone services in Hong Kong are dominated by several providers. It is said that there is a lack of competition in the market and some of the practices of these service providers are anti-competitive in nature.

    (a) Mobile phone service providers in Hong Kong offer various plans with different charges to their customers. Each plan includes a certain amount of airtime and additional services such as voice mail, call forwarding, free intra network SMS, etc. Usually, the per-minute charges for plans with more airtime are lower than those with less airtime.

    (i) What is price discrimination? (2 marks)

    (ii) State TWO conditions for practising price discrimination. Do the mobile phone service providers in Hong Kong meet those conditions? (4 marks)

    (iii) Consider that, apart from the amount of airtime, a certain service provider offers the same additional services to all customers. Is this pricing practice (charging a lower per-minute price for plans with more airtime) an example of price discrimination? Explain your answer.

    (4 marks)

    (b) In early 2000, all mobile phone service providers in Hong Kong announced an increase of $20 in the monthly charges at almost the same time.

    (i) Explain why all sellers in a competitive market would charge a higher price when there is an increase in the cost of production. (2 marks)

    (ii) Based on the answer to (b)(i), can we conclude that sellers behaviour in raising prices at the same time in a market is necessarily anti-competitive? What other evidence would be necessary to draw such a conclusion? Explain. (4 marks)

    Section C ( 16 marks ) Elective 1 12. .Mobile phone services in Hong Kong are dominated by several providers. It is said that there is a lack of competition in the market and some of the practices of these service providers are anti-competitive in nature. (a). Mobile phone service providers in Hong Kong offer various plans with different charges to their customers. Each plan includes a certain amount of airtime and additional services such as voice mail, call forwarding, free intra network SMS, etc. Usually, the per-minute charges for plans with more airtime are lower than those with less airtime. (i). (i). (i). What is price discrimination? (2 marks)

    (ii) .(ii) .State TWO conditions for practising price discrimination. Do the mobile phone service providers in Hong Kong meet those conditions? (4 marks)

    (iii) .Consider that, apart from the amount of airtime, a certain service provider offers the same additional services to all customers. Is this pricing practice (charging a lower per-minute price for plans with more airtime) an example of price discrimination? Explain your answer. (4 marks) (4 marks)

    (b) .In early 2000, all mobile phone service providers in Hong Kong announced an increase of $20 in the monthly charges at almost the same time.

    (ii). (ii). Based on the answer to (b)(i), can we conclude that sellers behaviour in raising prices at the same time in a market is necessarily anti-competitive? What other evidence would be necessary to draw such a conclusion? Explain. (4 marks)
