Chapter 10: Acid Rain on Others Parades (Externalities, Carbon Taxes, Free Riders, and Public Goods) Negative or positive externalities make smart private choice different from smart choices -Smart choices require that all additional benefit and additional opportunity costs— including externalities—be counted Negative externalities (external costs)—costs to society from your private choice that affect others, but that you do not pay Positive externalities (external benefits)—benefits to society from your private choice that affect others, but that others do not pay for -Externalities occur when no clear property rights exist -When externalities exist, prices don’t accurately reflect all social cost and benefits, preventing markets from coordinating private smart choices with social smart choices.
