6. Case Study 1
Two Ways To Reduce The quantity of Smoking Demanded
Public policymakers often want to reduce the amount that people smoke. There are two ways that
policy can attempt to achieve this goal.
One way to reduce smoking is to shit the demand curve for cigarettes and other tobacco
products. Public service announcements, mandatory health warnings on cigarette packages, and
the prohibition of cigarette advertising on television are all policies aimed at reducing the
quantity of cigarettes demanded at a given price. If possible these policies shift the demand curve
for cigarettes to the left.
Alternatively, policymakers can try to raise the price of cigarettes. If the government taxes the
manufacturers of cigarettes, for example, cigarette companies pass much of this tax on to
consumers in the form of higher prices. A higher price encourages the consumers to reduce the
numbers of cigarettes they smoke. In this case, the reduced amount of smoking does not
represent a shift in the demand curve. Instead, it represents a movement along the same demand
curve on a point with a higher price and lower quantity.
How much does the amount of smoking respond to changes in the price of cigarettes?
Economists have attempted to answer this question by studying what happens when the tax on
cigarette changes. They have found that 2% increase in price causes a 4% decrease in the
quantity demanded. Teenagers are found to be especially sensitive to the price of cigarettes. 10%
increase in price causes a 12% drop in teenage smoking.
A related question is how the price of cigarettes affects the demand for other drugs such as
marijuana. Opponents of cigarette taxes often argue that tobacco and marijuana are substitutes,
so that high cigarette prices encourage marijuana. There is another view which says that lower
cigarette prices are associated with greater use of marijuana. In other words, tobacco and
marijuana appear to be complements rather than substitutes.

Case Study 2
The DeBeers Diamond Monopoly
A classic example of a monopoly that arise from the ownership of key source is DeBeers, the
South African diamond company. DeBeers controls about 80% of the world’s production of
diamonds. Although the firm’s share is not 100%, it is large enough to exert substantial influence
over market price of diamonds.
How much market power does DeBeers have? The answer depends in part on whether there are
close substitutes for its product. If people view emeralds, rubies and sapphires as good
substitutes for diamonds, then DeBeers has relatively little market power. In this case, any
attempt by DeBeers to raise the price of diamonds would cause people to switch to other
gemstones. But if people view these other stones as very different from diamonds, then DeBeers
can exert substantial influence over the price of its product.
7

8. DeBeers pays for large amount of advertising. At first, this decision might seem surprising. If a
monopoly is the sole seller of its product, why does it need to advertise? One goal of DeBeers
ads is to differentiate diamonds and other stones in the minds of the consumers. When their
slogan tells you that “diamonds are forever,” you are meant to think that same is not true of
emeralds, rubies and sapphires. If the ads are successful, consumers feel that diamonds are
unique, rather than as one among many gemstones and this perception will give DeBeers greater
market power.
Activity 1
Stage 1
You have Rs 200 to spend. You can buy any of the products in any combination, but you must
make sure you spend all of your Rs 200. You may not spend more than Rs 200. Complete the
table below.
Product Quantities
Can of coke (Rs25)
Snickers bar (Rs 30)
1 Bottle milk (Rs15)
Cookies (Rs 30)
Stage 2
Today is a new day and you have consumed all the food you bought above yesterday - you have
no food at all at the moment.
8

9. A global shortage of peanuts has pushed the price of a Snickers bar up to Rs 35. All other
product prices remain the same. You still have Rs 200 to spend (which you must spend all of).
Complete the table below with your new shopping list.
Product Quantities
Can of coke (Rs25)
Snickers bar (Rs 35)
1 Bottle milk (Rs15)
Cookies (Rs 30)
Stage 3 - Calculating Market Demand
Add together the requests from each individual in your group for each product in stages 1 and 2.
This will give you the Market Demand for each product. Complete the table below.
Quantities - Stage 1 Quantities - Stage 2
Product
(Snickers 30) (Snickers cost 35)
Can of coke
Snickers bar
1 Bottle milk
Cookies
You can now see the Market Demand for Snickers bars at each of the prices in stages 1 and 2.
Draw the demand curve for Snickers bars below. Draw a straight line through the two co-
ordinates on the graph.
What sort of relationship exists between price and quantity demanded?
Stage 4 - Introducing Price Elasticity of Demand
You can now see responsiveness of quantity demanded to a change in price for Snickers bars.
Calculate the Price Elasticity of Demand using the formula:
Percentage change in quantity demanded
Price Elasticity of Demand =
Percentage change in price
9

10. Hint: To calculate a percentage change, divide the change in the value of a variable by the initial
value, then multiply by 100. For example, if demand for cans of coke rises from 7 to 10, then the
change in value is 3. Dividing 3 by 7 (the initial value) gives 0.43. Multiplying by 100 gives
43%.
Stage 5
It is now Day 3 and the peanut crisis has eased. Snickers bars now cost Rs 30 again. You have
consumed all the food you bought on Day 2.
The generosity of the government has provided all students with a grant and they now have to
spend Rs 300. Complete the tables below with your new shopping list, ensuring you spend all of
your Rs 300
Product Quantities
Can of coke (Rs25)
Snickers bar (Rs 30)
1 Bottle milk (Rs15)
Cookies (Rs 30)
Stage 6 - Introducing Income Elasticity of Demand
Complete the table below to show market demand for Snickers bars in stages 1 and 5. Make sure
you add up the demand from individuals in your group. This shows the difference in market
demand at different income levels.
Quantities - Stage 1 Quantities - Stage 5
Product
(Income is Rs 200) (Income is Rs 300)
Can of coke
Snickers bar
Pint of milk
Mars bar
You can now see the Market Demand for Snickers bars at the different income levels in stages 1
and 5. Draw the demand curve for Snickers bars below.
10

11. You can now see responsiveness of quantity demanded to a change in income for Snickers bars.
Calculate the Income Elasticity of Demand using the formula:
Percentage change in quantity demanded
Income Elasticity of Demand =
Percentage change in income
Stage 7 - Introducing Cross Price Elasticity of Demand
Take another look at the table above under 'Stage 3 - Calculating Market Demand'. What
happened to the quantities demanded of the other goods when the price of Snickers bars
increased? The responsiveness of quantity demanded of one product to a price change in a
related product is known as the Cross Price Elasticity of Demand and can be calculated using the
following formula:
Percentage change in quantity demanded of
Cross Price Elasticity of Demand = x
Percentage change in price of y
Calculate the Cross Price Elasticity of Demand for cans of coke, bottles of milk and cookies, and
plot the shift in the demand curve on the templates below.
Activity 2
Economic Concepts Covered in the Lesson Plan:
• Law of Diminishing Marginal Utility
• Opportunity Cost
• Utility
a. On the paper, students will rate the benefit of consuming a piece of candy based on a scale of
1-10. In economics terminology, this benefit gained from consuming a good or service is called
utility. 1 represents the lowest utility and 10 the highest utility. Those in the audience will also
conduct their own “virtual” rating as you imagine your level of utility of consuming the piece of
candy.
b. The scribe will collect the ratings from the five volunteers.
11

12. c. Distribute one piece of candy to each of the five volunteers and give the following
instructions:
d. Consume the piece of candy and once the volunteer has finished level of utility, based on a
scale of 1-10, is recorded.
e. Distribute the second piece of candy, have the volunteers rate their utility, ask the scribe to
record the ratings. The audience will also rate the second piece. Explain the difference between
utility and marginal utility.
f. Distribute the third piece of candy following the same procedure as above.
g. What do the students notice about the data?
h. Why do you suppose the marginal utility ratings declined?
i. At what point did the marginal utility of consuming begin to decline?
j. Is it possible that this same decline in marginal utility would occur for other items that we
consume? How about a t-shirt? What do you predict would happen to the marginal utility ratings
for the second, third and fourth for the exact same t-shirt?
k. Can you think of an example when the Law of Diminishing Marginal Utility would not hold
true, where an individual’s satisfaction or benefit would continue to increase?
