Many international projects involve pipelines connecting energy markets in two or more countries. A key feature of investment taking place in Latin America is the convergence of gas...

India and China contain about 40 percent of the earth's people. They are at an early stage of economic development, and their increasingly massive energy requirements will depend heavily on coal, a potent source of carbon dioxide, a powerful and long-lasting greenhouse gas. India also has...

Sound public policy addresses externalities directly, when possible. Air pollution is best alleviated by policy instruments that internalize the social cost of pollution, making it attractive to reduce emissions. One such instrument might be a tax levied on individual emissions, if they are...

Title IV of the 1990 US Clean Air Act Amendments established a market for transferable sulfur dioxide emission allowances among electric utilities. The market offers firms facing high marginal costs for pollution abatement the opportunity to purchase the right to emit sulfur dioxide from firms...

The authors survey past trends in vehicle ownership and road network expansion to analyze determinants of their growth at the national and urban level. Surprisingly, they find that: Nationally, income is a major determinant of both vehicle ownership and road length. Nationally, paved road length...
