Theme 1 Economics Flashcards
theme 1
External cost/benefit
The cost/ benefit to a third party not involved in the economic activity; the difference between social cost/benefit and private cost/benefit
Free market
An economy where the market mechanism allocates resources so consumers and producers make decision about what is produced, how to produce and for whom
Free rider principle
People who do not pay for a public good still receive benefits from it so the private sector will under-provide the good as they cannot make a profit
Government failure
When government intervention leads to a net welfare loss in society
Habitual behaviour
A cause of irrational behaviour; when consumers are in the habit of making certain decisions
Incidence of tax
The tax burden on the the tax payer
Income elasticity of demand (YED)
The responsiveness of demand to a change in income
Indirect tax
Taxes levied on goods and services which increase production and leads to a fall in supply, although this is often partially, or fully, passed onto consumers
Inferior goods
YED<); goods which see a fall in demand as income increases
Information gaps
When an economic agent lacks the information needs to make a rational informed decision
Labour
One of the four factors of production; human capital
Land
One of the four factors of production; natural resources such as oil, coal, wheat, physical space
Luxury goods
YED>1; an increase in incomes causes an even bigger increase in demand
Market failure
When the free market fails to allocate resources to the best interest of society, so there is an inefficient allocation of scarce resources
Market forces
Forces in free markets which act to reduce prices when there is excess supply and increase them when there is excess demand
Minimum price
A floor price which a firm cannot charge belwo
Model
A hypothesis which can be proven or tested by evidence; it tends to be mathematical whilst a theory is in words
Negative externalities of production
Where the social costs of producing a good are greater than the private costs of producing the good
Non- excludability
A characteristic of public goods; someone cannot be prevented from using a good
Non-renewable resources
Resources which cannot be readily replenished or replaced at a level equal to consumption; the stock level decreases over time as they are consumed
Non rivalry
A characteristic of public goods; one person’s use of the good does not prevent someone else using it
Normal goods
YED>0; demand increase as income increases
Normative statements
Subjective statements based on value judgments and opinions; cannot be proven or disproven
Opportunity cost
The value of the next best alternative forgone
perfectly price elastic good
PED/PED = Infinity; quantity demanded/supplied falls to 0 when price changes
Perfectly price inelastic good
PED/PES = 0; quantity demanded/supplied does not change when price changes
Positive externalities of consumption
Where the social benefits of consuming a good are larger than the private benefits of consuming that good
Positive statements
Objective statements which can be proven tested with factual evidence to be proven or disproven
Possibility production frontier (PPF)
Depicts the maximum productive potential of an economy, using a combination of two goods or services
Price elasticity of demand
The responsiveness of demand to a change in price
