Solution concept
Solution method

In the TEA model, international trade follows an Armington's aggregation1, 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.
