We describe the progress of computable general equilibrium (CGE) modeling software since the 1980s and contrast the main systems used today: GAMS, MPSGE and GEMPACK. The development of these general-purpose modeling systems has underpinned rapid growth in the use of CGE models, and allowed...

Validity is a key issue for consumers of computable general equilibrium (CGE) modeling services. What assurance can producers of CGE results give to consumers that a CGE analysis: (i) is computationally sound, (ii) uses accurate up-to-date data, (iii) adequately captures behavioral and...

MONASH models are descended from Johansen's 1960 model of Norway. The first MONASH model was ORANI, used in Australia's tariff debate of the 1970s. Johansen's influence combined with institutional arrangements in their development gave MONASH models distinctive characteristics, facilitating a...
