The Hidden Price Tag: Externalities and the Real Cost of Things

This lesson, The Hidden Price Tag: Externalities and the Real Cost of Things, teaches students how market prices often fail to show the full social and environmental costs of everyday goods and services. Students learn the difference between negative externalities, such as pollution from gasoline or coal-fired power plants, and positive externalities, such as honeybee pollination and herd immunity from vaccines. The lesson also explains true social cost, carbon taxes, subsidies, and regulation as tools governments can use to address hidden costs and benefits. Students analyze how economic choices affect communities, ecosystems, public health, and Earth systems.
