Variability in Economic Analysis

Chapter 10 - "Evaluating Projects with the Benefit-Cost Ratio Method" in Engineering Economy (Sullivan, Wicks, & Koelling, 2014)

Chapter 10 explains that because of the methods of financing, the absence of tax and profit requirements, and political and social factors, the criteria used in evaluating privately financed projects frequently cannot be applied to public works. The benefit-cost ratio (B-C) has remained a popular method for evaluating the financial performance of public projects.
