Nature of Economics Flashcards
(28 cards)
Ceteris Paribus
a Latin phrase meaning “all things being equal”; it is used in economics when we focus on changes in one variable while holding other influences constant
Postive economic statement
a statement based on fact which can be tested as true or false and are value-free
Nominative economic statement
a statement based on VALUE JUDGEMENTS which cannot be test as true or false.
what indicates a nominative economic statement
value laden words: ought, should, fair, unfair, better or worse)
Economic problem
a problem based on the problem of scarcity i.e. when there are UNLIMITED WANTS but FINITE RESOURCES with which to SATISFY them. Therefore, choices have to be made and resources have to be allocated between competing uses
Opportunity cost
the value forgone of the next best alternative
economic agents
groups within the economy
Factors of production
C optical
E nterprise
L abour
L and
Renewable resource
natural resources that can be replenished e.g. solar energy that does not get used up
The catch with renewable resources
renewable resources may decline over time if consumed at a faster rate than the environment can replenish them
non-renewable resources
natural resources that once used cannot be replenished e.g. coal or oil
a PPF
a Production Possibility Frontier is a curve showing the maximum potential output for two goods or services that an economy can achieve when all its resources are fully and efficiently employed
marginal costs
the cost of producing an additional unit of output
opportunity cost w/ a straight line PPF
opportunity cost of a straight line PPF is constant b/c resources are of equal quality and equally suited to the production of both goods
opportunity cost w/ concave line
the opportunity cost increases = the more of one good is produced, an increasing amount of the other good is forgone b/c not all resources are as efficient as other resources in the production of both goods = diminishing returns (after a period of time, you gain less return for the same input)
consumer good
a good which directly provides utility to consumers
capital good
a good which is used to produce consumer goods or services
PPF graph - outward shifts causes
economic growth / anything that improves the quality / quantity of the factors of production (i.e. an advancement in technology or mass immigration)
PPF graph - inward shifts
economics shrinks, war, natural disasters, depression unemployment
PPF graph - employment
‘X’ under the line = unemployment
‘X’ on the line = full employment (b/c def of PPF)
‘X’ over the line - over employment
PPF graph - increase in productivity in the production of ONE good
outward shift that increases as you make more of that good
Specialisation
occurs when an individual / firm / region / country concentration on the production of a limited range of goods or services
advantages of specialisation
increases output / productivity and living standards across the world
disadvantages of specialisation (4)
- resource depletion
- over-reliance on imports
- a fall in demand may = significant increase in structural employment
- developing countries may face an unfavourable exchange rate
