Unit 2B: Should governments intervene in markets? (microeconomics) Flashcards
Define underallocation
When too few resources are allocated to the production of a good relative to what is socially most desirable.
Define negative externalities of consumption
The negative affects suffered by a 3rd party when a good or service is consumed
Define social costs
These are the true (or full) costs born by society as a result of the economic actions of producers and consumers i.e. the sum of private costs and external costs.
The equation for social costs:
External costs + Private costs
Define private costs
These are the costs borne by the individual economic units (individuals, firms, government). And example of a private cost is wage costs.
Define social benefits
These are the full benefits enjoyed by society/the community as a result of the actions of consumers and producers.
Equation:
Social benefits = Private benefits + External benefits
Define rivalrous
Goods and services are referred to as this when the consumption by one person or a group of people prevents others from consuming the same good.
Define imperfect information
This exists when some stakeholders in an economic transaction have greater access to knowledge than others
Define negative externalities of production
These are the negative affects suffered by a 3rd party when a good or service is produced
Define equilibrium/market clearing
It is when demand equals supply. It is a state of balance with no tendency to change.
Define government regulations
A type of government policy where governments enact regulations in the publics interest
Define external costs
Any costs above and beyond private costs. negative affects suffered by 3rd parties as the result of consumption or production of a good/service for which no compensation is paid.
Define the term ‘excludable’
Goods and services are referred to as this when it producers prevent a person or persons from consuming that good or service based on their willingness to pay/other factors
Define disequilibrium
A state of imbalance where this is either excess demand (shortage) or excess supply (surplus). The forces of demand and supply will cause the price to change until an equilibrium is reached.
Define the term ‘allocative inefeciency’
A loss of economic efficiency that can occur when the equilibrium for a good or service is not allocatively efficient.
Define positive externalities of consumption
These are the benefits enjoyed by a 3rd party as a result of the consumption of a good/service
Define the term ‘external benefits’
The advantages enjoyed above and beyond private benefits. These are the benefits enjoyed by a 3rd party as a result of the production/consumption of a good/service.
Define government provision
The involvement of the government in the direct provision of goods/services with positive consumption externalities (e.g. providing healthcare or education)
Define private benefits
These are the advantages enjoyed by individual economic units (firms, individuals, governments). An example of a private benefit is sales revenue.
Define legislation
A type of government policy where the government uses its authority to enact laws in the publics interest
Define the free rider problem
This occurs when people who benefit from the consumption of goods and services do not have to pay for them, thus there is overconsumption. This happens when consumers try to ‘ride on the backs’ of other consumers to maximise utility. It happens because of the non-excludable nature of public goods. As others cannot be prevented from enjoying the benefits of them there is no incentive to pay for them. This is why pure public goods are not provided in a free market, and the government thus has to step in and provide them.
Define positive externalities of production
The beneficial affects enjoyed by a 3rd party when a good or service is produced
Define overallocation
Occurs when too much of a resource is allocated to the production of a good relative to what is socially most desirable, leading to overproduction
What are the advantages and disadvantages of a market system?
Define a market failure
Market failure occurs due to inefficiency in the allocation of resources, and, therefore, in the production of goods and services. A price mechanism fails to account for all of the costs and benefits involved when providing or consuming a specific good, leading to overproduction of some goods and under-production of others.
What are the 6 types of market failure?
- Externalities
- the lack of provision of public goods by private firms (so the government has to step in and provide them)
- The underprovision and underconsumption of merit goods (the government has to step in and ‘top up’ the merit goods provided by private firms at subsidised rates or free of charge
- The overprovision and overconsumption of demerit goods (government has to step in and prevent or regulate or tax their production and consumption)
- The abuse of monopoly power
- Factor immobility
Explain what externalities (in general) are and why they are bad
Externalities are when the actions of consumers or producers affect 3rd parties.
If externalities exist then profits and prices do not represent the true costs and benefits to society of economic activity. This leads to a misallocation of resources, too much or too little of a good is produced.
Explain how negative externalities occur
Negative externalities occur either when external costs are greater than private costs and there is overproduction, or when private benefits are greater than external benefits and there is thus overconsumption.
An example is the second hand smoker who inhales the smoke of someone else’s cigarette.
