Subject Specific Vocabulary Flashcards
Key definitions and subject vocab for micro
Positive statement
A statement that can be tested against the facts or
evidence.
Normative statement
A statement that cannot be refuted just by looking at data or
evidence.
Economic activity
The production, consumption, exchange and distribution of goods and services.
Economic resources (factors of production)
The inputs into the production process that are needed to produce the goods and services
that satisfy people’s wants. They are usually classified as land, labour, capital and enterprise.
Land
The factor of production that includes all the natural resources that are available on the earth.
It includes the land and sea.
Capital
The human-made factor of production. Examples of capital include machines, tools, lorries
and buildings.
Labour
The human resource. The contribution made by people to the production of goods and
services
Entrepreneur
The person who organise the other economic resources to allow goods
and services to be produced.
Enterprise
Enterprise involves making decisions and taking risks.
Scarce resource
A factor of production that is limited in supply. There are not enough available to satisfy.
people’s needs and wants.
Scarcity
The fundamental economic problem that results from limited resources and unlimited wants.
It means that choices have to be made which have an opportunity cost.
Opportunity cost
The next best alternative foregone when a choice is made.
Production possibility diagram
Shows the quantities of two goods or services that can be produced with the available
resources, given the current state of technology.
Production possibility boundary (PPB)
The PPB is also known as the production possibility curve (PPC) and the production possibility
frontier (PPF). It shows the various quantities of two goods or services that can be produced,
with the current state of technology, when all the available resources are fully employed.
Resource allocation
How the available factors of production are used to produce different goods and services. The
allocation of resources involves determining what is produced, how it is produced and for
whom it is produced.
Rational economic decision making
Using all the available information to select the best option to maximise the welfare of the
decision maker. A rational consumer chooses to buy the goods and services that, given their
limited income, will maximise their total utility.
Utility
The satisfaction that is derived from consuming a good or service.
Marginal utility
The change in total utility that results from the consumption of one more, or one fewer, goods
or services.
Diminishing marginal utility
The proposition that as more of a product is consumed, the additional satisfaction gained
from each extra unit declines.
Imperfect information
When an economic agent does not have all the information needed to make a rational
decision, or the information is distorted in some way.
Asymmetric information
A type of imperfect information where one party to an economic transaction has more
information than the other party.
Behavioural economics
A branch of economics that includes elements of psychology to improve our understanding of
how people’s decision making is influenced by biases and emotional factors.
Bounded rationality
The idea that human limitations mean that people’s decision making is not completely
rational. Bounded rationality means that when an individual makes a decision, they choose an
option that is satisfactory rather than optimal.
Bounded self-control
The idea that people do not have sufficient willpower or self-discipline to resist choices that
may be tempting but are not in their self-interest.
Rules of thumb
Mental shortcuts, based on experience, that enable individuals to make decisions more
quickly and easily.
Anchoring
The idea that when making decisions, people rely too heavily on one particular piece of
information, the anchor. The anchor is often the first piece of information they encounter.
Availability bias
When people’s decision making is unduly influenced by recent events or how easily an event
comes to mind.
Social norms
Behaviours that are consistent with what is generally considered acceptable by society at the
present time.
Choice architecture
The way or framework in which choices are presented to people.
Nudge
Something that encourages a particular decision or behaviour without removing freedom of
choice.
Default choice
An option that has been pre-selected for an individual but the individual is able to select a
different option if they want to.
Restricted choice
Where the number of choices made available to an individual is limited. This type of choice
architecture is often adopted when there is a large number of choices available which makes
it hard for individuals to decide which is the best option.
Mandated choice
A form of choice architecture where the individual must make a decision. Mandated choices
are usually required by law.
Demand curve - (REMEMBER a curve always shows a relationship)
The relationship between the price and quantity demanded of a good or service, in a given
period of time, when other things that affect demand are held constant.
Price elasticity of demand
A measure of the extent to which the quantity demanded of a product changes in response to
a change in the price of the product.
Income elasticity of demand
A measure of the extent to which the quantity demanded of a product changes in response to
a change in income.
Cross elasticity of demand
A measure of the extent to which the quantity demanded of a product (A) changes in response to
a change in the price of a different product (B).
Normal good
A product where there is a positive relationship between income and the quantity demanded
of the product, eg a rise in income leads to a rise in the quantity demanded.
Inferior good
A product where there is an inverse relationship between income and the quantity demanded
of the product, eg a rise in income leads to a fall in the quantity demanded.
Supply curve - (REMEMBER curves always show a relationship)
The relationship between the price and quantity supplied of a good or service, in a given
period of time, when other things that affect supply are held constant.
Price elasticity of supply
A measure of the extent to which the quantity supplied of a product changes in response to a
change in the price of the product.
Equilibrium market price
The price at which the quantity demanded equals the quantity supplied and there is no
tendency for the price to change.
Disequilibrium price
A price at which there is either excess demand, and a tendency for the price to rise, or there is
excess supply, and a tendency for the price to fall.
Excess demand
The amount by which the quantity demanded exceeds the quantity supplied at the current
price.
Excess supply
The amount by which the quantity supplied exceeds the quantity demanded at the current
price.
Joint demand
When two products are demanded together so that the demand for one product is directly
related to the demand for the other product. Complementary goods such as printers and
printer cartridges are in joint demand.
Competitive demand
When the demand for one product increases the demand for another product decreases.
Substitute goods such as butter and margarine are in competitive demand.
Composite demand
When a product has more than one use so that an increase in the demand for one use leads
to a fall in the supply of the product that is available to use elsewhere. For example, milk is
used to produce cream and cheese.
Derived demand
When the demand for a product, or factor of production, is determined by the demand for a
different product. For example, the demand for steel is derived from the demand for cars,
and a number of other products.
Joint supply
When the output of one product also results in the output of a different product. For example,
sheep farming can lead to the supply of both meat and wool.
Production
The process of using factors of production to create goods and services.
Productivity
A measure of how much a factor of production can produce in a given period of time. For
example, the productivity of land might be measured by output per hectare per year. It is a
measure of efficiency.
Labour productivity
A measure of how much a worker can produce in a given period of time. For example, output
per person per hour.
Specialisation
Where firms, regions, countries or factors of production concentrate on producing a
particular good or service, or carrying out a particular task.
Division of labour
When the production of a good is broken down into many separate tasks and each worker
performs one task, or a narrow range of tasks, as part of the production process.
Short run
The time period when there is at least one fixed factor of production.
Long run
The time period when all factors of production are variable.
The law of diminishing returns
The law states that as more of a variable factor of production is used in combination with a
fixed factor of production, both the marginal and average returns to the variable factor of
production will initially increase but will eventually decrease.
Returns
The amount produced, ie the output of a good or service.
Marginal returns
The change in total output that results from employing one more unit of a variable factor of
production when the amount employed of all other factors of production is unchanged.
Average returns
Average returns to a variable factor of production is calculated by dividing total output by the
number of units of the variable factor that are employed.
Total returns
Total output.
Returns to scale
The effect on total output when all factors of production are changed. It relates to the long
run when all factors of production are variable.
Increasing returns to scale
Increasing returns to scale
When a given percentage increase in all factor inputs leads to a greater percentage increase in
output.
Constant returns to scale
When a given percentage increase in all factor inputs leads to the same percentage increase
in output.
