1.1 The nature of the economic problem
Scarcity. The resources available are insufficient to satisfy all the unlimited human needs and wants. Therefore,
we must all make choices about how we use our limited resources by deciding what G&S we will produce and
What is the basic economic problem? consume.
Non-renewable resources cannot be replaced in time for humans to consume considering the rate in which we

supply? Renewable resources take time and more finite resources to be produced.
1.2 The factors of production
Definition of production The using up of resources/FoP to produce G&S to satisfy human wants and needs
Two types of products Goods and services
What is a productive activity? using inputs (4FoP) to produce outputs (G&S)
Definition of a 'not productive activity' any activity/G&S that fails to satisfy a human need or want
Definition of 'producers' The people and organisations which combine FoP to produce G&S
Why is it impossible to satisfy all human Human wants=unlimited
wants? Resources=scarce relative to human wants/limited
Difference between human need and human Human needs=essential to human survival, can be satisfied
want. Human wants=not necessary for human survival, can never be fully satisfied
Definition of 'free goods' items that we may need or want that are without limit and freely available, and the production of it incurs zero

Definition of 'consumption' the using up of G&S to satisfy human needs and wants
Definition of 'consumers' the people and organisations that buy G&S to satisfy some of their wants
Definition of 'consumption expenditure' the total amount consumers spend each period on economic goods
Consumers engage in trade or exchange with producers to obtain those economic goods they cannot produce
themselves to satisfy their wants. Can be monetary exchange (consumer pay with their wages) or barter
What is exchange? economy (exchange good with good).
To increase the production capacity of a firm. (Allocating more resources to the production of capital goods will
Why should we invest in capital goods? reduce the amount of resources available to produce consumer G&S.)
Definition of 'consumer good' an economic good that satisfies an immediate consumer need or want
consumer durables
non-durable goods
3 types of consumer goods consumer services
Definition of 'capital goods' economic goods that don't satisfy any immediate human needs or wants
What is an 'investment' the purchase of capital goods
Definition of 'Factors of Production (FoP)' the scarce resources we use up in the production of G&S to satisfy human needs and wants
Capital (man-made machinery needed to produce output)
Enterprise (the ability to organise production in a firm)
Labour (human skills and effort needed to produce output)
What are the 4FoP? (extras: in notes) Land (natural resources obtained from land)
What are 'factor rewards' the payment different FoP require and receive in order to participate in productive activity
Why do we need them? Producers are motivated by monetary returns to supply scarce resources to other firms.

Enterprise-profits
Labour-wages
4 types of factor returns (extra: in notes) Land-rent
Formula for profits Total revenue−total costs
the ease with which resources or FoP can be moved from one productive activity to another without incurring

between industries
4 movement patterns of FoP between different countries

allows different FoP to be moved into their best possible uses
enables firms to improve efficiency of production as the quantity and quality of FoP changes
Importance of factor mobility allows firms to change the type of G&S they produce as human needs and wants change
Occupational mobility (move among different productive activities)
2 types of factor mobility Geographic mobility (move among different places)
Explain the factor mobility of each of the FoP.

Definition of 'resource allocation' economic welfare
Consumers must choose what to buy out of their limited incomes to satisfy as many of their wants as possible.
Producers must choose what to produce with their limited resources to maximise profits. Governments must
choose what services to provide out of their limited tax revenues.

1.4 Production possibility curves
(PPC)
Complete term of PPC/PPF Production possibility curve/production possibility frontier
The PPC shows the maximum combined output of two or more products a firm or an entire economy can
Purpose of a 'PPC' produce with its scarce resources when all resources are fully and efficiently employed
A, B, C: efficient use of resources X (point under the PPC): inefficient use of resources Y (point beyond the
What is A, B, C, X, Y? PPC): currently unattainable, given the current level of FoP
Fully/not fully utilising the maximum amount of FoP as efficiently as possible
X: increase total output of both products
Y:
improve quality of existing resources
Correction of X and Y increase quantity of resources it employs
What causes the movement along PPCs? The reallocation of resources from the production of one product to another.
Definition of 'economy' any area in which the economic activities of production, exchange, and consumption take place
Currently, there are 200 units of bags and 50 units of shoes being produced per day. To move from D to E, the
firm reallocates the factors of production from the production of bags to the production of shoes, now 70 units of
Describe the movement from D to E in this bags and 150 units of shoes are produced per day, so the opportunity cost of producing 100 more units of shoes
PPC. is the production of 130 units of bags.
