Answer:
A) give sellers the incentive to account for the external effects of their actions.
Step-by-step explanation:
The effect of levying a tax that represents the cost of the externality could lead to one of two outcomes:
- Firms that are causing the externality add the cost of the externality in the final price of their products.
- Firms that are causing the externality attempt to reduce or eliminate the externality, so that prices remain the same, and competitiveness is not lost.
For example, the most common example of an externality is pollution, therefore, the industrial sector operates in a market characterized by negative externalities. If the government levied a tax on factories accounting for the pollution they produce, these factores either would increase prices, or try to reduce pollution.
