Difficult environmental cases and the role of government

As the world continues to grapple with environmental challenges such as climate change, pollution, and biodiversity loss, governments are faced with the daunting task of developing policies and regulations that balance economic growth with environmental protection. From an economic perspective, these decisions can be difficult, as they often involve trade-offs between short-term economic gains and long-term environmental sustainability.

One of the most significant challenges facing governments today is climate change. As global temperatures rise, the effects are becoming increasingly apparent, from more frequent and severe natural disasters to rising sea levels threatening coastal communities. While reducing greenhouse gas emissions is necessary to mitigate the worst effects of climate change, it can also have economic implications.

For example, industries that rely heavily on fossil fuels, such as the oil and gas sector, may face significant economic losses if policies are implemented to reduce their carbon footprint. At the same time, there is growing evidence that investing in renewable energy and other low-carbon technologies can create new economic opportunities and jobs.

Another environmental challenge that governments must address is pollution. While some types of pollution, such as air pollution, can have significant health impacts, others, such as plastic pollution, can harm ecosystems and wildlife. Governments can play a critical role in addressing these issues through policies such as taxes on polluting industries, regulations on the use of harmful chemicals, and incentives for companies to adopt cleaner technologies.

However, these policies can also have economic consequences. For example, companies that rely on single-use plastics may face higher costs if they are required to switch to more environmentally friendly alternatives. Similarly, industries that rely on chemicals that are harmful to the environment may face increased costs if they are required to adopt safer alternatives.

Biodiversity loss is another pressing environmental issue that requires government intervention. The loss of species and habitats can have significant economic impacts, as it can reduce the availability of natural resources and disrupt ecosystems critical to human well-being. Governments can address this issue through policies such as protected areas, habitat restoration, and conservation programs.

However, these policies can also have economic implications. For example, restrictions on using natural resources in protected areas may limit economic opportunities for industries such as logging and mining. At the same time, investing in conservation programs and habitat restoration can create new economic opportunities in areas such as eco-tourism and sustainable agriculture.

In conclusion, environmental challenges such as climate change, pollution, and biodiversity loss require government intervention. While policies and regulations aimed at protecting the environment can have economic implications, the long-term benefits of environmental sustainability often outweigh the short-term costs. As such, governments need to develop policies that balance economic growth with environmental protection and to work with industry and other stakeholders to find innovative solutions that promote both economic prosperity and environmental sustainability.

1.The mitigation approach to reducing global warming involves:

the provision of subsidies to nonpolluting firms

making changes in the living habits of people only when global temperatures rise

reducing carbon emissions, primarily by government regulation, to keep global temperatures from rising

the provision of tax exemptions to polluting firms

2.Government regulation is often sought precisely in cases of environmental pollution because:

the harms associated with an economic activity are known and certain

the source of a problem cannot be demonstrated in a court of law

the benefits of reducing the harm are certain

the government always protects the interest of the polluting firms

3.The «tragedy of the commons» refers to:

the underutilization of a common resource

the overexploitation of a resource that is privately owned

the ownership of common resources by the government

the overexploitation of a resource that is not privately owned

4.With regard to global warming, the empirical evidence indicates that:

increases in carbon dioxide in the atmosphere will cause global temperatures to rise by at least 10 degrees in the next 75 years

the increase in carbon dioxide, over thousands of years, is the primary cause of global warming

there is uncertainty about the magnitude of global temperature increases accompanying rising levels of carbon dioxide in the atmosphere

if global warming continues at the rate of recent decades, the sea level will rise by at least ten feet by 2075

5.Which of the following is an effort to establish property rights and promote more efficient allocation of ocean fisheries?

Regulations limiting the length of the fishing season

Regulations reducing the size of fishing boats and other equipment used in the industry

Complete open access of ocean fishing to anyone who would like to enter the business

Establishment of individual transferable fishing quotas

6.The fish in the ocean are:

allocated efficiently because there are no limitations on entry into the ocean fisheries business

scarce, but only because of the highly restrictive regulations imposed by various nations

privately owned and therefore they are allocated efficiently

a commonly owned, open-access resource and therefore they are often over-exploited

7.A wealthier society with higher per capita income is more likely to:

demand more environmental quality

adopt labor-intensive techniques of production

have a higher number of monopolies than competitive firms

be less interested in the adoption of safety measures of all kinds

8.It is difficult to define and enforce property rights against damaging pollutants when

there are good substitutes for the goods and services produced by the polluters

there are a large number of polluters and the damages imposed by specific polluters are difficult to identify and quantify

the benefits and costs imposed by the polluting emissions are easily measurable

most people believe our planet is on a disastrous course that will result in massive destruction

9.With regard to environmental programs and regulations, economic analysis indicates that

income levels exert little impact on the demand for environmental quality

the cost of an environmental policy matters little if it improves the quality of the environment

environmental quality is something that people value and, therefore, are willing to pay for

people value many other things, but environmental values always come first

10.In 2009, the Environmental Protection Agency (EPA) began:

regulating carbon dioxide as a pollutant and developed plans to control emissions of carbon dioxide from factories and power plants

lobbying for the imposition of taxes on factories and plants that emit nitrogen oxide

introducing the «cap-and-trade» system to control air pollution

developing plans for controlling the discharge of solid wastes into water bodies

11.The adaptation strategy to deal with global warming would:

make it relatively easy to acquire the information needed to measure both the benefits and costs of future global warming

be efficient if the regulations adopted by the 2015 Paris Climate Change Agreement were followed

ensure that immediate action be undertaken to eliminate potential harms imposed by global warming

focus on dealing with the uncertainties of global warming as problems arise and delaying major action until better information on the benefits and costs of potential policy alternatives is available

12.The process of levying a pollution tax will result in efficient emission controls only if the emission charges represent:

the average cost of the pollutant to those harmed

the marginal cost of the pollutant to those harmed

the sunk cost of the polluters

the total cost of the pollutant to society

13.In the context of environmental pollution, which of the following is true of private property rights?

They can never be defined when there are a small number of polluters

They can be fully protected when a large number of people are harmed by emissions

They fail to optimize decisions to produce greater net social benefits from activities that pollute

They help optimize decisions to produce greater net social benefits from activities that pollute

14.Which of the following is true under the «cap-and-trade» policy?

Firms that can cheaply reduce emissions below their allowed level can sell emissions permits to other companies that face higher costs

Firms cannot trade emission permits with each other in order to reduce the level of pollution to the level set by the pollution-control authority

Each polluting firm will be forced to shut down if it pollutes beyond permissible levels

A polluting firm is forced to reduce its level of pollution to zero

15.Which of the following would provide firms that pollute with an incentive to reduce the level of their pollution emissions?

A reduction in the corporate profit tax rate

Setting a price floor on the firms’ products

Subsidizing pollution emissions

Levying a charge or tax that increases with emission levels

16.Which of the following provides the best example of the «tragedy of the commons»?

Smoking cigarettes in a public place

Loud music being played by a neighbor

Discharge of toxic wastes by a factory in a river

Overfishing in the oceans

17.Which of the following will happen if the emission taxes imposed by the government reduce pollution?

Government revenue from the pollution tax will decrease over time

The average cost of production of the polluting firms will decrease over time

The general price level will fall

Total output in the economy will increase

18.Which of the following strategies is likely to be adopted by the government to cope with the «tragedy of the commons»?

Defining property rights only when there are a limited number of polluters

Taking ownership of all commonly owned resources

Implementing regulations that prevent the overexploitation of commonly owned natural resources

Instituting regulations that protect the rights of encroachers

19.Which of the following is true of the «cap-and-trade» policy?

It allows the government to ban firms from operating in a market if they pollute beyond permissible levels

It allows a pollution-control authority to set the total amount of emissions and issue tradable permits authorizing a specified amount of emissions that sum to the total

It allows emitters to pollute in unlimited amounts after paying a fixed surcharge

It encourages each emitter to continue with its amount of emissions without any regulation

20.The estimates of benefits and costs of policy alternatives to reduce carbon dioxide emissions as a means to deal with global warming:

are clear and indisputable

are characterized by both wide variation and imprecision

are irrelevant to economists

indicate global warming should be stopped regardless of cost
