The TASTE program has been designed to allow a large number of users to analyze existing trade policies and perform tariff scenarios. It is based on the MAcMap-HS6 database (version 2, baseyear 2004). It addresses several needs in terms of trade policy analysis. Among them:

The standard GTAP Model is a multiregion, multisector, computable general equilibrium model with perfect competition and constant returns to scale. Innovative aspects of this model include: (i) the treatment of private household preferences using the non-homothetic CDE functional form and (ii) the explicit treatment of international trade and transport margins. Bilateral trade is handled via the Armington assumption. A global banking sector intermediates between global savings and consumption.

The IMPACT model is a representation of a competitive world agricultural market. It is specified for 30 crop and livestock commodities, including cereals, soybeans, cotton, roots and tubers, meats, milk, eggs, oils, sugar/sweeteners, fruits/vegetables, and fish. It is specified as a set of 115 countries and regions within each of which supply, demand, and prices for agricultural commodities are determined.

The Economy-Wide Multi-Market (EMM) model is based on neoclassical microeconomic theory. In the model, an aggregate producer represents a specific zone’s production of a specific sector. In this application for Ethiopia, there are a total of 2,352 (42 sub-sectors x 56 zones) such representative producers. Consistent with the setup of many other multi-market models, the supply function, rather than the production function, is used to capture each representative producer’s response to market conditions.
