1.1 Nature of Economics Flashcards
(40 cards)
why is Economics a social science?
Economists develop models to explain how the economy works, for example theories of supply and demand or the circular flow of income. These are developed by putting forward a model, gathering evidence and then accepting, changing or disregarding the model.
Ceteris Paribus
meaning ‘all other things remaining equal’. For example, when there is a change in income, demand will shift, ceteris paribus.
Positive Statement
a statement which can be supported with evidence and fact
Normative statement
Those which are value based and involve opinions
the role of value judgements
Value judgements can influence economic decision making and policy. Different economists may make different judgements from the same statistic, for example rising inflation could mean different things.
what is the problem of scarcity?
where there are unlimited wants and finite resources
unlimited needs –> problem of <– limited
and wants Scarcity resources
what are the three economic questions?
-what to produce?
-how to produce?
-for whom to produce?
the four economic agents
-government
-consumers
-suppliers
-employees
what do the government aim to achieve?
aim to maximise social welfare
what do consumers aim to achieve?
aim to maximise satisfaction
what do suplliers aim to achieve?
aim to maximise profit
what do employees aim to achieve?
aim to maximise income
centrally planned economy
communism
ceterus paribus
everything remains equal
production possibility frontiers
shows the maximum possible output combinations of two goods or services an economy can achieve when all resources are fully and efficiently employed
What are the 4 resources?
-capital
-entrepreneurs
-labour
-land
Factors that shift the PPF
-increasing wages
-better benefits
-invest in better technology
-invest in to education
-invest in the green industry
absolute advantage
being able to produce more of something
than another country (assuming both have the same amount of resources avaliable)
comparative advantage
-being able to produce something at a much lower oppourtunity cost
advantages of specialisation
-workers become better producing goods
-an increase in productivity causes the cost of production to decrease
-increased output
-higher wages for staff
-more motivation
disadvantages of job specialisation
-greater costs of training workers
-quality may suffer if workers get bored
-more expensive workers
-repetitive job
-skills of workers become limited
-eventually workers will be replaced by machinery
-may become reliant on a country for imports
-might lead to over extraction of a country’s natural resources
how to work oppourtunity cost for specilisation
OCA=B/A
OCB=A/B
how do we know who should specialise
the country with the lower oppourtunity
advantages in division of labour
-improved organisation
-increased output and better quality
-get better at one job
-increased productivity
-increased efficiency
-less training costs
