Chapter 10 FINAL Flashcards
(52 cards)
equilibrium in a free market yields what results
- goods must be produced at the lowest possible cost
- goods must satisfy the highest valued demands
- total surplus (consumer + producer surplus) is maximized
externality
the uncompensated impact of one person’s actions on the well-being of a bystander
externalities cause markets to be ____ & thus fail to ____
inefficient; maximize total surplus
an externality arises when
a person engages in an activity that influences the well-being of a bystander and yet neither pays nor receives any compensation for that effect
negative externality
when the impact on the bystander is adverse
positive externality
when the impact on the bystander is beneficial
examples of negative externalities
automobile exhaust, cigarette smoking, barking dogs, loud music in apartments
examples of positive externalities
immunizations, restored historic buildings, research into new technologies
negative externalities lead markets to
produce a larger quantity than is socially desirble
positive externalities lead markets to
produce a larger quantity than is socially desirable
private cost
a cost paid by the consumer or producer
private benefit
a benefit received by the consumer or the producer
external cost
a cost paid by people other than the consumers or the producers trading in the market
external benefit
a benefit received by people other than the consumers or producers trading in the market
social cost
the cost to everyone, the private cost + the external cost
social benefit
the benefit to everyone, the private benefit plus the external benefit
when making decisions, consumers & producers
typically focus on private costs and benefits while ignoring external costs and benefits
when consumers and producers ignore externalities, the market equilibrium can be
less than optimal
social surplus=
consumer surplus plus producer surplus plus everyone else’s surplus
social surplus is not maximized when
externalities are present
when consumers and producers ignore external costs, they base their decisions on
private costs only
costs are underestimated, and the market quantity is greater than the socially efficient level
wehn external costs are ignored
the market quantity is greater than the socially efficient level, and social surplus is reduced
reducing output below the market quantity increases social surplus when
the social cost exceeds buyers’ private benefit
to maximize social surplus output should be
reduced to the socially efficient level
