what information does a government need if it wants to attempt to reduce a widespread negative externality like air pollution

Government can discourage negative externalities by taxing goods and services that generate spillover costs. Government can encourage positive externalities by subsidizing goods and services that generate spillover benefits. The gov. needs information like maybe how many people die a year because of it or the complains of people in the environment.

Hope this helps:) Have a great day!
