Model information
Institution Institute of Communication And Computer Systems (ICCS)
Concept General equilibrium
Solution method The model is formulated as a simultaneous system of equations with an equal number of variables. The system is solved for each year following a time-forward path. The model uses the GAMS software and is written as a mixed non-linear complementarity problem solved by using the PATH algorithm using the standard solver options.
Anticipation Myopic

Population and population growth are exogenous to the GEM-E3 model. Projections on the EU countries up to 2050 have been extracted from the “2015 Ageing report” prepared by the European Commission. For non-EU countries the ILO projections are used.
