World Agricultural Trade SImulation Model

Until 2002

WATSIM is a recursive-dynamic, spatial world trade model for agricultural commodities. In its current version, it covers 12 regions and 29 commodities. Simulations are running from the year 2000 to 2010. Policies covered are ad-valorem and specific tariffs, tariff rate quotas (TRQs), safeguards (flexible tariffs), export subsidies, and production quotas. These policies are explicitly modelled by formulating the model as an MCP (mixed complementarity problem). The most important application of WATSIM is the medium-term analysis of trade policy changes.
