How do positive and negative externalities affect the cost-benefit analysis of a hydropower project? Choose the answer with a correct example.

Accepted Answer

Both positive and negative externalities impact costs and benefits. A new reservoir could offer recreational opportunities (positive), while land loss for other uses is a negative externality.
