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.
