Population - COFFEE-TEA

From IAMC-Documentation
Jump to: navigation, search
The TEA model relies on the Shared Socioeconomic Pathways (SSPs) database as a reference for the demographic scernarios. Most applications are based on the population projections of the SSP2 scenario1.

Solution concept The models can run scenarios as a stand-alone application or linked through a soft-link process.
Solution method The COFFEE model is solved through Linear Programming (LP). The TEA model is formulated as a mixed complementary problem (MCP) and is solved through Mathematical Programming System for General Equilibrium -- MPSGE within GAMS using the PATH solver.
