Institution	COPPE/UFRJ (Cenergia), Brazil, http://www.cenergialab.coppe.ufrj.br/.
Solution concept	General equilibrium (closed economy)
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.
Anticipation

In the TEA model, international trade follows an Armington's aggregationarmington1969theory, in which a composite CES function differentiate consumer's preferences between imported and domestic goods.

In the COFFEE model, international trade of energy and agriculture commodities is explicitely represented. Partial equilibrium is reached in a minimun cost basis, whereas trade between regions is part of the solution.
