Chapter 1
1. Explain the concept of opportunity cost.
Opportunity cost is the value of the next best alternative which must be forgone in order to obtain
a good or service. For example, the cost of doing these exercises and reading this answer might
be the TV you could have watched.
2. List goods, or services, that compete for your income. Similarly, list activities that
compete for your time. In deciding what you will spend your income on and how you will
allocate your time, do you minimize your opportunity costs?
Goods or services competing for your income might include rent, food, heating and travel.
Activities competing for your time might include studying, work, sleep and leisure activities, such
as the cinema, drinking and sport.
In assessing whether you minimize your opportunity costs you need to examine what you decided
to do, or consume, and compare these with what you decided not to do or consume. If you
minimized your opportunity costs, then you have chosen all the things that provide you with the
maximum amount of benefit.
3. Consider whether it is ever possible to solve the problem of scarcity.
The problem of scarcity cannot ever be resolved. Resources are finite and wants are unlimited.
For example, if we discover new oil fields in the world, this does not mean that the oil supply is no
longer finite. At some point we will stop finding oil. Nor does the new discovery stop the world’s
demand for oil increasing.
4. An economy produces two goods, Ferraris and Ray-Ban sunglasses. Using a
production possibility frontier assess what must happen to the production of Ferraris, if
the production of Ray-Ban sunglasses decreases.
If the production of Ray-Ban sunglasses reduces, then resource such as labour will become
available. This underutilised resource can be hired by Ferrari and so the production of Ferraris
could increase.
5. The same Ferrari and Ray-Ban economy receives an influx of migrant workers. What do
you think will happen to the production possibility frontier for this economy?
An influx of migrant workers is an addition to the labour resource in an economy. With more
resource, more output can be produced. So, the production possibility frontier will move outwards
to the right.
6. How does the production possibility frontier illustrate the concept of opportunity cost?
,It depicts the trade-off between goods and/or services produced. As resources are used for the
production of one commodity those resources cannot be used for the production of another good
or service.
7. Why does the law of diminishing returns require the production possibility frontier to be
curved, rather than a straight line?
The slope of the production possibility frontier shows the opportunity cost of increasing the
production of one type of good or service. For example, as more capital goods are produced the
opportunity cost in terms of consumer goods foregone increases. This could result from the fact
that some resources are more efficient in the production of one type of good, or that changing the
proportion of factors employed in one form of production causes the output to increase at a
decreasing rate. This is explained by the law of diminishing returns and gives the P.P.F a circular
appearance.
8. Explain the resource allocation mechanism within a market economy and also a planned
economy.
The recourse allocation mechanism within a market economy is the price mechanism/system. It
is based on the idea of a competitive market in which no individual can influence the price of
factors of production and no single firm can influence the market price of its product. A market
exists when buyers and sellers of a particular commodity are in communication for the purpose of
exchange. Market forces operate to satisfy the desire of one person to sell something and the
desire of another to buy it. A price is agreed which is acceptable to both the buyer and the seller.
Price acts as the mechanism which equalises the demand for and supply of a commodity.
A planned economy is a system in which all economic decisions are made by the central
authorities; unlike the price/market system which assumes in its purest state no government
interference in economic activity. In a command or planned economy a central planning body
makes all the basic economic decisions, the state owns or controls all the factors of production
and determines what to produce by assessment of consumer needs and the requirements of the
state. Priorities are drawn up and production quotas set accordingly.
9. Using examples, highlight why your own economy is probably best described as a
mixed economy.
A mixed economy is an economy in which decisions are made partly by the state and partly by
individuals and firms. In Britain the production and sale of groceries is a market solution with
private firms supplying consumers via supermarkets and similar outlets. Health care for most
British people is provided by the state. Hence Britain is a mixed economy.
10. State whether the following relate to macroeconomics or to microeconomics:
(a) During the last 12 months average car prices have fallen;
(b) inflation for the past 12 months has been 3.5 per cent;
(c) strong sales in the housing market have prevented the Bank of England from reducing
interest rates.
,(a) The price of cars is a microeconomic issue. It is an issue associated with one market, or
sector. (b) Inflation is the rise in prices across the entire economy and, therefore, represents a
macroeconomic problem. (c) Strong sales in the housing market are a micro issue as they relate
to a single market. However, the housing market is linked to the macroeconomy and, in this
example, has led to the Bank of England holding interest rates constant. As interest rates are set
for the whole economy, this is a macroeconomic issue.
11. True or False?
a) Economics is about human behaviour and so cannot be a science.
b) An expansion of the economy’s productive capacity would be reflected in an
outward movement of the production possibility frontier.
c) China is an example of a command economy in which private markets play no part.
d) When you make a choice there will always be an opportunity cost.
e) Firms should operate in the interests of their wider stakeholders is an example of a
normative economic statement.
f) Economists assume that business operates in a purely economic environment
a) False. Economics is a social science
b) True. As the production possibility frontier moves out, then more of both goods can be
produced.
c) False. China in the last 30 years has increasingly moved towards a market based
economy.
d) True. A choice means that one thing is chosen and so something else is foregone.
Opportunity cost the cost of foregoing the other choice.
e) True. It is a statement of opinion, not a statement of theory.
f) False. Economists are interested in understanding the economic environment that
businesses operate in, but they also recognise the social and political environment of
business.
12. Answer the following:
(a) List the four economic factors of production.
(b) China's economy has a lot of which factor of production?
(c) More education increases the quality or the quantity of labour resource in an
economy?
a) The factors of production are Land, Labour, Capital and Enterprise.
, b) China has the largest population in the world and a greater proportion of those people
have entered paid employment in the last 20 years, so China has a lot of Labour. China
also has a lot of space, geographically it is a large country, but in terms of Economic
Land Resource, China does not have a lot. It imports oil, gas, iron and copper ore etc
from other economies.
c) More education has the potential to improve learner’s skills, which we would expect to
improve their productivity in employment, i.e. workers with more education make more
units of output or a higher value of output per day. So, education can be said to have the
potential to raise the quality of labour.
13. The price of a medium latte is £3.50 in 2025, £3.90 in 2026 and £4.35 in 2027.
a) By setting 2025 = 100, calculate the latte index for 2026 and 2027.
b) How much latte inflation was there between 2025 and 2026, i.e. what was the
percentage increase in the price of a latte?
a) 2025 = 100, 2026 = 111.4 (3.90/3.50)x100, 2027 = 124.3 (4.35/3.50)x100.
b) 111.4-100 = 11.4% latte inflation.
14. Differentiate between micro and macro: Inflation, Rivals, Profits, Price, Consumers,
Workers, Exports, Government Spending, Interest Rates, Competition, Foreign Exchange
Rates.
(a)The microeconomic topics listed above are:
(b)The macroeconomic topics listed above are:
a) Microeconomic topics are related to markets and agents in markets such as firms and
consumers, so the microeconomic topics are:
Rivals, profits, price, workers, competition
b) Macroeconomic topics are related to economic activity or topics that apply across the
