The price of gasoline in Europe is about three times that in the United States, mainly because the European gas tax is higher than the U.S. gas tax. In light of the principles you've learned in this chapter, what is the case for and against increasing the gas tax in the United States to the European level? 1.The marginal social cost of carbon emissions from road vehicles exceeds the marginal social benefit . 2. The marginal social benefit of carbon emissions from road vehicles exceeds the marginal social cost. 3. A pollution tax is the only way of moving toward a more efficient outcome. 4. A pollution tax is the most efficient tool available for achieving a more efficient outcome. 5. Not everyone agrees that the scientific evidence points to human activity in global warming and climate change. 6. The cost of avoiding climate change is present and certain but the benefit of avoiding climate change is future and uncertain. 7. By 2050, if current trends persist, three quarters of greenhouse gas emissions will be from the developing countries, not the United States.
Proposition 1 is the best case for and propositions 5, 6, and 7 are the best case against.
Explain the inefficiency in Beijing's market for electricity and contrast it with the US market. How can cap-and-trade achieve an efficient outcome>
The Beijing market for electricity is inefficient because electricity production has a large external cost arising from carbon emissions from coal-powered generators. Comparing the U.S. market for electricity and the Beijing market for electricity, the U.S. market is less inefficient. Cap and trade is efficient when: confronting power utilities with the marginal social cost of their production
Beijing officials issued a "red alert" for air quality, closed schools, limited automobile traffic, and kept people indoors to avoid toxic smog. Most of Beijing's energy comes from carbon-emitting coal. The U.S. EPA is working with China to develop a national cap-and-trade system. Explain the inefficiency in Beijing's market for electricity and contrast it with the U.S. market. How can cap-and-trade achieve an efficient outcome?
The Beijing market for electricity is inefficient because: electricity production has a large external cost arising from carbon emissions from coal-powered generators Comparing The U.S. market for electricity and the Beijing market for electricity, the U.S. market is LESS inefficient Cap-and-trade can achieve an efficient outcome by CONFRONTING POWER UTILITIES WITH THE MARGINAL SOCIAL COST OF THEIR PRODUCTION

eventually the market price of an emission permit equals the marginal external cost of the pollution produced
