How many hours per week should this person exercise to maximize satisfaction?d. What is the maximum number of net benefit points that can be earned from exercising?

• Externalities exist when the market fails to register fully costs and benefits.
– External costs:• When the actions of an individual or group
incur a cost to 3rd party.
– External benefits:• Present when the actions of an individual or
group generate benefits for 3rd parties.
• All of the costs of production are not considered
• the supply curve understates the true cost of production.
• Lower production costs mean more output.
• Too many units are produced.• Pollution problems are often a side
effect.
• With a negative externality, too many units are produced at a price below that which would prevail if all costs were identified and factored into the market process.

• The demand curve understates the total value of the output.
• Units that are more highly valued than their costs may not be produced.
• From society’s viewpoint, too few units may be produced.
• With a positive externality, too few units are produced at a price below that which would prevail if all the benefits were identified and factored into the market process.

Study of economic motives and attitudes of voters and public officials in collective decision making.
• Maximizing Behavior and the Voting Process– A person’s decision about whether or
not to vote in an election depends on his or her marginal benefit and marginal cost of voting.
Public Choice 11-4
• Voters support candidates who will provide them with the most government services and transfer benefits, net of personal costs.
• Rational Ignorance Effect: Recognizing their vote is unlikely to be decisive, most voters have little incentive to obtain information on issues and alternative candidates.
• Because of the rational ignorance effect, voters will be uninformed on many issues; such issues will not enter into their decision making process.
Public Choice Analysis• Voter incentives:
– Rational Ignorance• Choosing to remain uninformed because the
marginal cost of obtaining the information is higher than the marginal benefit from knowing it.
– Special Interest Group• People who share a common position on a
particular issue and actively promote that position.
11-4
• The Politician-Supplier:• Political officials must win elections to be
successful and achieve their goals.
• Rationally uninformed voters often must be convinced to “want” a candidate. $$$
• Legislative bodies are something like a Board of Directors. They …•establish the general direction of policy, •appoint and supervise bureaucrats who
carryout the day-to-day operations of government, and,
•set the budgets of agencies and bureaus.
