解释:
Externalities can occur due to environmental factors, such as pollution or social factors, for example, when companies fail to pay a minimum wage. When externalities are negative, private costs are lower than societal costs. Internalization of these externalities could significantly impact the costs and profits of companies’ products and services, affecting their bottom line.
