1. Alternative approaches for reducing carbon dioxide emissions are

    burning low carbon coal and deforestation.
    carbon taxes and carbon scrubbing.
    carbon taxes and carbon trading.
    carbon trading and carbon subsidies.

QUESTION 2

1. The Coase Theorem asserts that

    if trade in an externality is possible and there are low transaction costs, bargaining will lead to an efficient outcome regardless of the initial allocation of property rights.
    Bargaining between the parties to an external cost of production can never lead to an efficient market solution to deal with the externality.
    there is no solution to the problem of market externalities
    the government must always directly intervene with a command and control policy to deal effectively with a negative externality such as pollution.

QUESTION 4

1. Which of the following is not an advantage of risk pooling?

    Individuals who are insured and therefore do not have to pay the full cost of health care services may be inclined to over-use those services.
    It is easier for an insurance company to estimate the average number of claims likely to be filed under a group policy than it is to predict the number of claims likely to be filed under an individual policy.
    It gives very sick people in the group the same access to health care and to pay the same premiums as healthy individuals.
    By insuring large groups as opposed to individuals, health insurance providers reduce adverse selection.

QUESTION 5

1. The cost of group health insurance is lower than if an individual buys a policy on his own because

    insuring a group eliminates the problem of buyers having more information than the seller.
    moral hazard costs of a group tend to move to a low average.
    it is easier for the company to deny claims from a large group.
    the problem of adverse selection is reduced.

QUESTION 6

1. Some environmentalists are skeptical  about the appointment of  Judge Amy Coney Barrett to the Supreme Court  and her interpretation of Administrative Law because:

    She said that she is very knowledgeable about climate science in her Senate testimony
    She graduated from Harvard and is therefore biased
    She might uphold the court’s decision in  Massachusetts vs. EPA
    Climate change wasn’t included in the original mandate of the EPA, and Congress has never explicitly told the agency to regulate greenhouse gas emissions,

QUESTION 9

1.

Referring to figure 5-7 above, and assume that we are trying to reduce carbon emissions.  If poor forest management caused  the recent California Wildfires, then that would mean:

 

    the Marginal Benefit of Reducing Pollution curve shifts to the left (decreases) if the wildfires had little to do with carbon emissions.
    the efficient level of pollution reduction is QA
    there is no way to estimate the benefits and costs of carbon emission reduction, so this framework is only theoretical.

QUESTION 11

1. Social Security Disability Insurance (SSDI) and Supplemental Security Insurance programs, the US government provides disability insurance to all, providing monthly income to the disabled through (in the case of SSDI) premiums levied on the healthy. The government does this because:

    it has pushed out private insurers in this market.
    when all group members (workers) pay the premium, the problem of adverse selection is reduced.
    such insurance does not meet the criteria for an incomplete market.
    the US Constitution mandates all citizens to buy social insurance.

QUESTION 12

1. Conceptually, the efficient level of carbon emissions is the level for which

    the marginal benefit of reducing carbon emissions is maximized.
    the marginal benefit of reducing carbon emissions is minimized and the marginal cost of reducing carbon emissions is maximized.
    the marginal benefit of reducing carbon emissions is equal to the marginal cost of reducing carbon emissions.
    the marginal cost of reducing carbon emissions is minimized.

By offering health insurance to all U.S. citizens with pre-existing medical conditions, the Pre-Existing Condition Insurance Plan eliminates ________ for both the insurer and the insured, and eliminates ________ for the issuer of the insurance policy.

QUESTION 19

1. In a market with negative externalities (e.g. large-scale meat packing and offshore oil exploration), equilibrium price does not reflect full marginal social cost, and like a subsidy, this leads to excessive production and consumption of the good.

QUESTION 20

1. Mariana Mazzucato draws connections between government spending on general purpose technologies (GPTs) and increases in innovation for consumer products. She asserts that:

Chicken pox vaccinations for toddlers benefit society by protecting young children and by preventing an epidemic of the disease. Thus, the social benefits of chicken pox vaccinations exceed the private benefit for any quantity of vaccinations as illustrated in Figure 5-10.

Refer to Figure 5-10.  One way to obtain the economically efficient amount of chicken pox vaccinations is for governments to subsidize these vaccinations. What is the size of the per-vaccination Pigovian subsidy that the government must provide to internalize the external benefits?
