Imagine that you have been hired to undertake a public benefit-cost analysis of the economic feasibility of this new bridge. The method of analysis could involve (1) listing all of the costs and benefits associated with the entire life of the project inclusive of the opportunity costs and any positive and negative externalities; (2) monetizing all of the costs and benefits and (3) using a discount rate to the convert all costs and benefits to their net present value (NPV) and summing the totals. If the benefits exceed the costs, then the project satisfies the criteria to be eligible for approval. Describe five issues that could impact the accuracy of your work.
