GEMPACK General Equilibrium Modelling Software

GEMPACK (General Equilibrium Modelling PACKage) is a suite of general-purpose economic modelling software. It is especially suitable for computable general equilibrium (CGE) models, but can handle a wide range of economic behaviour.
  • GEMPACK enables modellers to solve very large systems of non-linear equations.
  • Once the model equations have been specified using an algebra-like notation, modellers are freed from the computing details of the solution process.
  • The GEMPACK software calculates accurate solutions of the economic model.
  • All features of the software (basic and advanced) are fully documented.
  • The documentation contains detailed instructions (including many hands-on examples). This makes it easy for new users to start using the software.
  • GEMPACK Windows programs make the software easy to use on a Windows PC.
  • GEMPACK contains powerful capabilities for solving recursive-dynamic and fully-intertemporal models.
  • Prompt feedback is given when problems are reported.
  • GEMPACK is used in over 400 organisations in over 70 countries (press report).
  • Latest version is GEMPACK Release 10.001 with these new features and these recent improvements.
