- Answer: c) Natural resource allocation and sustainability
- Explanation: Environmental Economics examines how economic activities interact with the environment, focusing on sustainability and resource management.
- What is an externality in economic terms?
- a) A price charged for pollution
- b) A side effect of economic activity that affects others
- c) A tax on carbon emissions
- d) A regulation imposed by the government
- Answer: b) A side effect of economic activity that affects others
- Explanation: An externality occurs when the costs or benefits of an economic activity are not reflected in the market price, affecting third parties.
- Which of the following is an example of a negative externality?
- a) Public parks
- b) Education subsidies
- c) Air pollution from factories
- d) Investment in renewable energy
- Answer: c) Air pollution from factories
- Explanation: Air pollution is a negative externality because it imposes health and environmental costs on society not reflected in the market price.
- What is the “Tragedy of the Commons”?
- a) The depletion of a common resource due to overuse
- b) The economic principle of free-market capitalism
- c) A policy to regulate public goods
- d) The expansion of private property rights
- Answer: a) The depletion of a common resource due to overuse
- Explanation: The “Tragedy of the Commons” refers to the over-exploitation of shared resources, leading to their depletion and environmental degradation.
- Which of the following is a method used to address negative externalities?
- a) Free-market pricing
- b) Subsidies for pollution
- c) Pigovian taxes
- d) Price controls
- Answer: c) Pigovian taxes
- Explanation: Pigovian taxes are designed to internalize the social costs of negative externalities by taxing activities that cause pollution or environmental harm.
- What is the main difference between renewable and non-renewable resources?
- a) Renewable resources can be replenished naturally, while non-renewable resources cannot
- b) Non-renewable resources are cheaper to extract
- c) Renewable resources are always more expensive
- d) Non-renewable resources are sustainable over time
- Answer: a) Renewable resources can be replenished naturally, while non-renewable resources cannot
- Explanation: Renewable resources, like solar and wind energy, can be replenished naturally, whereas non-renewable resources, such as coal and oil, are finite.
- Which policy approach involves trading pollution permits between companies?
- a) Carbon tax
- b) Cap-and-trade system
- c) Subsidy for clean energy
- d) Ban on emissions
- Answer: b) Cap-and-trade system
- Explanation: Cap-and-trade systems set a cap on emissions and allow companies to trade permits to pollute, incentivizing pollution reduction.
- What is “Green GDP”?
- a) The total income generated by environmental activities
- b) GDP adjusted for the environmental costs of economic activities
- c) GDP generated by green technology industries
- d) A measure of government spending on environmental protection
- Answer: b) GDP adjusted for the environmental costs of economic activities
- Explanation: Green GDP accounts for environmental damage and resource depletion, providing a more accurate picture of sustainable economic growth.
- Which of the following is an indicator of environmental sustainability?
- a) Ecological footprint
- b) Nominal GDP
- c) Unemployment rate
- d) Inflation rate
- Answer: a) Ecological footprint
- Explanation: The ecological footprint measures the environmental impact of human activities, particularly in terms of resource consumption and waste generation.
- What is the primary goal of international environmental agreements like the Paris Climate Agreement?
- a) To regulate international trade policies
- b) To reduce global carbon emissions and mitigate climate change
- c) To increase global production of fossil fuels
- d) To promote economic development in developing countries
- Answer: b) To reduce global carbon emissions and mitigate climate change

Long Descriptive Questions with Answers
- Discuss the concept of sustainability in Environmental Economics.
- Answer: Sustainability in environmental economics refers to the ability of an economy to support the needs of the present without compromising the ability of future generations to meet their own needs. It emphasizes the importance of balancing economic growth with the preservation of natural resources and ecosystems. Sustainable practices ensure that resources are used efficiently and conserved for the long-term, reducing environmental degradation and promoting social well-being.
- Explain the role of government intervention in addressing environmental externalities.
- Answer: Government intervention is essential in addressing environmental externalities because markets often fail to account for the social costs or benefits of economic activities. Government policies, such as imposing Pigovian taxes, providing subsidies for renewable energy, and regulating pollution, help internalize externalities. By doing so, governments can encourage firms and individuals to consider the environmental impact of their actions, leading to more sustainable economic practices.
- What is the “Tragedy of the Commons,” and how can it be prevented?
- Answer: The “Tragedy of the Commons” refers to the overuse of common resources, such as fisheries, forests, and clean air, leading to their depletion or degradation. It occurs because individuals acting in their self-interest deplete the resource, even though it is in everyone’s interest to conserve it. Solutions include implementing property rights, establishing regulations, and promoting cooperative management of common resources to ensure their sustainable use.
- Analyze the economic impact of climate change on agriculture.
- Answer: Climate change has a significant economic impact on agriculture by altering weather patterns, increasing the frequency of extreme weather events, and affecting crop yields. Changes in temperature, rainfall patterns, and the availability of water resources can lead to lower productivity, increased costs for irrigation and pest control, and reduced food security. These effects threaten the livelihoods of farmers, especially in developing countries, and can cause global food price volatility.
- Explain the role of renewable energy in achieving sustainable development.
- Answer: Renewable energy, such as
solar, wind, and hydropower, plays a crucial role in achieving sustainable development by providing cleaner alternatives to fossil fuels. By reducing greenhouse gas emissions and decreasing reliance on non-renewable resources, renewable energy contributes to environmental sustainability and helps mitigate climate change. Additionally, the expansion of renewable energy technologies fosters economic growth by creating jobs in clean energy sectors and enhancing energy security.
