Econ chapter 10
the socially optimal quantity of output is
73 units
without government intervention, the equilibrium quantity would be
Q3
the social optimum can be reached if
a subsidy of $36 is applied to each unit of the good
Each unit of plastics that is produced results in an external
cost of $8
If this market is currently producing at Q4, then total economic well-being would be maximized if output
decreases to Q2
Suppose planting flowering shrubs creates a positive externality equal to $7 per shrub. Further suppose that the local government offers a $7 per-shrub subsidy to planters. The number of shrubs that are planted is then
equal to the socially optimal quantity
If an externality is present in a market, economic efficiency may be enhanced by
government intervention
negative externalities lead markets to produce
greater than efficient output levels and positive externalities lead markets to produce smaller than efficient output levels
in order to reach the social optimum, the government could
impose a tax of $8 per unit on plastics
When an externality is present, the market equilibrium is
inefficient, and the equilibrium does not maximize the total benefit to society as a whole
in many cases selling pollution permits is a better method for reducing pollution than imposing a corrective tax because
it is hard to estimate the market demand curve and thus charge the "right" corrective tax
This market is characterized by
negative externality
Research into new technologies provides a
positive externality, and too few resources are devoted to research as a result
suppose that cookie producers create a positive externality equal to $2 per dozen. what is the relationship between the equilibrium quantity and the socially optimal quantity of cookies to be produced?
the equilibrium quantity is less than the socially optimal quantity
Suppose that smoking creates a negative externality. If the government does not interfere in the cigarette market, then
the equilibrium quantity of cigarettes smoked will be greater than the socially optimal quantity of cigarettes smoked
suppose that a steel factory emits a certain amount of air pollution, which constitutes a negative externality. if the market does not internalize the externality,
the market equilibrium quantity will not be the socially optimal quantity
