Final answer:
If congress passed much stricter laws to control air pollution caused by businesses, it would reduce pollution emissions by requiring businesses to install anti-pollution equipment and account for the social costs of pollution.
Step-by-step explanation:
If congress passed much stricter laws to control the air pollution caused by businesses, this action would tend to reduce the amount of pollution being emitted by businesses. Stricter laws would require businesses to install anti-pollution equipment, increase their costs, and account for the social costs of pollution in their production decisions. These laws would fall under the category of command-and-control regulation, which sets limits on pollution emissions and requires specific pollution-control technologies to be used.
