Background Information
 In the beginning of May, two chain supermarkets started a
price war by decreasing the price of pork to the average
of $19 per catty.
 The effect spread to the wet market as their price was
higher than the supermarkets.
 The wholesalers deeply opposed to this policy and
blocked the slaughter houses at Tsuen Wan and Sheung
Shui.
Many wholesalers accused that
Ng Fung Hong sells pork to
Park’N Shop at a lower price.
Here are the reasons
why Ng Fung Hong do this
Park’N Shop buys pork in bulk
Sells in bulk to a single buyer (Park’N)
will reduce the average cost of the seller
Thus, seller usually gives discount to the
buyer who buys in bulk
Why Park’N Shop
decreases the price of
the pork?
Reason 1
 If Ng Fung Hong sells
pork to Park’ N Shop at a
lower price, the cost of
Park’ N Shop in selling
pork decreases.
The supply of pork
increases.
Price decreases and the
quantity increases.

As pork has a lot of
substitutes, the demand

less than the percentage

the revenue will increase.

Other Reason
The market structure of supermarket in Hong
Kong belongs to oligopoly.
Wellcome & Park’N Shop dominate the market.
They enjoy brand name and goodwill so entry of
new seller is difficult.
They are interdependent. Whenever one of them
lowers the price to attract more business, the
other will follow.
So when one of them reduce the price of pork,
the other will follow.
