The traditional cost-benefit analysis (CBA) for transport appraisal has two key weaknesses. Firstly, by assuming static prices in markets external to transport, externalities cannot be considered other than in an ad-hoc, case-by-case manner.

We introduce a maximum entropy approach to parameter estimation for computable general equilibrium (CGE) models. The approach applies information theory to estimating a system of nonlinear simultaneous equations. It has a number of advantages. First, it imposes all general equilibrium constraints. Second, it permits incorporation of prior information on parameter values. Third, it can be applie...
