Economic appraisal is the process of determining the impacts and merit of a proposal. This includes presenting relevant information for consideration by decision-makers.

This guide describes various economic appraisal techniques and how to apply them when developing a submission to Infrastructure Australia. This set of technical guidelines supports our Assessment Framework. 

The guidelines cover cost–benefit analysis (the standard technique for economic appraisal) as well as other techniques, such as cost-effectiveness analysis, computable general equilibrium models, and input–output analysis.
