The outputs of CGE (computable general equilibrium) models do not usually play a role in CBA. CGE models focus on 'economic activity impacts', which are not a measure of efficiency effects.
Infrastructure Australia does not encourage stakeholders to undertake CGE modelling. However, it recognises that some initiatives will have CGE information available which will be included in submissions to Infrastructure Australia.
Infrastructure Australia will primarily use CBA data for measuring the benefits of an initiative and will not consider CGE benefits as additive or complimentary to CBA benefits.
