Market Structure
Perfect Competition(Perfectly competitive market)
Imperfect Competition(Imperfectly competitive market)
![Page 7: Economics Chapter 7 Competition and Market Structure.](https://reader035.fdocuments.in/reader035/viewer/2022062221/56649e7a5503460f94b79fbb/html5/thumbnails/7.jpg)
Competition
Definition Under scarcity, both buyers and sellers want to gain more
from the market transactions. Buyers bargain for lower prices and more gifts. Sellers compete for more customers and a larger profit. Hence, competition exists in all markets
Forms of competition Price competition (Price War)
Firms promote sales by cutting prices. Non-price competition
Firms use ways other than price reduction to promote sales E.g. better product quality, advertising, gift, after-sale
service

Nature of productHomogeneous vs. Heterogeneous
Homogeneous products Products which are completely the same. Products are made by mass production.
Examples Coca-Cola: The same product being sold in
supermarkets / convenient shops / stores. Newspaper: Some product at different news-
stand.
![Page 12: Economics Chapter 7 Competition and Market Structure.](https://reader035.fdocuments.in/reader035/viewer/2022062221/56649e7a5503460f94b79fbb/html5/thumbnails/12.jpg)
Nature of productHomogeneous vs. Heterogeneous
Heterogeneous Products sold are no the same in terms of
Products Other factors
Examples Hand made art craft : Unique, can be similar, but
not the same. Food: Hamburger in McDonalds & Mos Burger.
![Page 13: Economics Chapter 7 Competition and Market Structure.](https://reader035.fdocuments.in/reader035/viewer/2022062221/56649e7a5503460f94b79fbb/html5/thumbnails/13.jpg)
From homogeneous to heterogeneous
Case 1: Mr. A lives in TKO. SCMP: $6 SCMP sold at TKO news-stand ≠ SCMP sold at Lantau Island Reason: Mr. A prefers to buy a newspaper near his living place.
Case 2 Pocari Sweat (ionic drink) Drink sold in Sports Ground ≠Drink sold in the supermarket Reason: Sportsmen need the drink a.s.a.p. after playing sports.

Compete with substitute MTR vs. Bus / Taxi / Ferry
Compete with factors of production Labours / Land / Capital
Compete with other’s franchises MTR vs. TKO Tunnel
Compete for social acceptance Will the gov’t extend the franchise / entry barrier?
![Page 25: Economics Chapter 7 Competition and Market Structure.](https://reader035.fdocuments.in/reader035/viewer/2022062221/56649e7a5503460f94b79fbb/html5/thumbnails/25.jpg)
Why does Monopoly exist?
1. Restricted by law Gov’t ownership
The government is the sole supplier Public enterprises in HK E.g. water supply, CLP in Kowloon & HK Light in HK Island
Gov’t franchise (franchised monopoly) A privilege the gov’t grants to a firm Transport utilities in HK E.g. Star Ferry, KMB, MTR
Patent and copyright Patent: Exclusive owners/users of their inventions Copyright: Exclusive owners/users of their works (authors & artists)

Why does Monopoly exist?
2. Natural monopoly Hugh entry cost
Extremely high fixed cost at the beginning Economies of scale
Expansion of firm Lower AC The firm can then lower the price Other firms have comparative high cost can’t survive Become natural monopoly
E.g. Water supply and electricity supply
![Page 27: Economics Chapter 7 Competition and Market Structure.](https://reader035.fdocuments.in/reader035/viewer/2022062221/56649e7a5503460f94b79fbb/html5/thumbnails/27.jpg)
Why does Monopoly exist?
3. Exclusive ownership of essential resources for production Resources are rare and owned by one firm
E.g. De Beer owns the world major diamond mines The reservoirs are owned by HK Government Extraction of petroleum by China National Petroleum Corpor
ation (中國石油天然氣集團公司 )
