Chapter 8 in Tietenberg and Lewis looks at climate change, the most important environmental issue of our time. Economists generally agree that putting a price on carbon is the best approach to reducing climate warming carbon emissions.

Why do economists favor these kinds of market-based strategies to pollution control over “command and control” approaches such technology standards?
