... 85 S t e p 8 8.1 Goal The goal of this step is to identify and analyze additional indirect effects (often referred to as WEBs) in order to provide a full accounting of the final effects of the project(s)

... 86 Guide for Conducting Benefit-Cost Analyses of Multimodal, Multijurisdictional Freight Corridor Investments In principle, a fully specified BCA would need to take a general equilibrium approach, examining surpluses that occur in each of the relevant markets, and then adjust these surpluses for double counting where relevant. In the United Kingdom, however, these are approximated in a simpler additive framework (instead of a general equilibrium model)

Analyze Higher-Order Quantifiable Metrics 87 8.2 Tasks Determine Whether WEBs Should Be Considered Determine whether the conditions are present in the scenarios to be analyzed for WEBs to be considered. Four such conditions can arise in large-scale projects: • Induced demand from network effects.

... Analyze Higher-Order Quantifiable Metrics 89 the tool is developed primarily for addressing highway connectivity to terminals; a second caveat is that the elasticity factor ignores lags and assumes the productivity gain is instantaneous, which could lead to overestimation if results are not phased out over time. Change in the Regional Access or Capture Area.

... Analyze Higher-Order Quantifiable Metrics 91 Consider Using Producer and Consumer Surplus for Capacity Contexts. For transformational large-scale projects, when it is difficult to use logsums, consider using the surplus as a first approximation, since the demand for the project is a derived demand.

... 92 Guide for Conducting Benefit-Cost Analyses of Multimodal, Multijurisdictional Freight Corridor Investments 8.4 Inputs: Recommended Tools and Data Sources WEBs can be considered as both epistemic, aleatory uncertainty and deeper uncertainty. A number of tools can assist the analyst with the analysis of higher-order quantifiable metrics in the near term: • Table 13.
