producers fear that cocoa bean growers will not be able to keep up with demand.
(GCE O/L

Figure 1 below shows the demand and supply of cocoa beans, the main ingredient of
chocolate.

II.
Is the elasticity of supply of cocoa beans likely to be elastic or
inelastic? (1)

b) Examine the arguments for and against a government subsidizing public
transport services. (12)

Spain is the world’s largest producer of olive oil. In 2005 production of olive oil fell due
to Spain’s worst drought since records began.
a) Draw a demand and supply diagram to show:
i.
The equilibrium price and quantity before the drought, (3)
ii.
The equilibrium price and quantity after the drought. (2)
i.
Define price elasticity of demand. (2)

Coffee prices on world markets averaged about $1.20 per pound weight in the 1980s
but byn2003 had fallen to only $0.50 per pound weight. Annual coffee production has
been rising at an annual rate of 3.6% whilst demand has been growing by only 1.5%.
(GCE O/L
January
2007/Q3)
a) With the aid of a demand and supply diagram , explain why coffee prices fell
from $1.20 per pound weight in the 1980s to $0.50 per pound weight in 2003.

b) What effect would the fall in coffee prices have on the price of tea? Explain
your answer. (3)

Cigarettes are widely considered to be demerit goods. In the past high taxes have been
placed on cigarettes, but because demand is price inelastic this has had little effect on
sales. Canada , Norway and other countries have banned smoking in public places.
(GCE O/L
January
2007/Q4)
a) What is meant by a DEMERIT GOOD? (2)
b) Give TWO possible reasons why governments have introduced anti-smoking
measures.(2)
c) With the aid of a diagram , explain what is meant by the phrase ‘Demand is
price inelastic’. (4)
d) Briefly describe ONE other measure governments could use to decrease sales
of cigarettes. (2)
7
a) What is meant by CROSS ELASTICITY OF DEMAND? (2)
b) With the aid of examples, identify the relationship between pairs of goods
whose cross elasticity of demand is :

i.
Positive (2)
ii.
Negative (2)
Imports of apples of Britain have increased. The result is that producers in Britain are
facing falling prices for their apples.
a) Draw a diagram to show :
i.
The demand and supply of British apples before imports increased, (2)
ii.
A new demand or supply curve to show why the price of British apples
has fallen, (1)
iii.
The new price and quantity demanded and supplied. (1)

(GCE O/L

b) Give TWO reasons why the British Government might want to reduce the
amount of imported apples. (2)
c) Identify and briefly explain ONE method which :
i.
The government could use to9 increase the demand for British apples.

Calculate the income elasticity of demand as income rises from $10,000 to $15,000 per
annum for :
i. Product A (2)
ii. Product B (2)

about the two products. (4)

that demand increases from 100 units a week to 150 units a week.

Saudi Arabia is the world’s largest exporter of crude oil and 75% of government
revenue comes from oil exports. It is essentially a one commodity economy. In times
when the demand for oil is strong , revenue is high , but in times of weak oil prices,
revenue can fall.
(GCE O/L
January
2003/Q3)
Explain, with reference to priced elasticity of demand, why “In times when the demand
for oil is strong, revenue is high , but in times of weak oil prices, revenue can fall” (5)
