User manual and handbook on Agricultural Trade Policy Simulation Model (ATPSM)

The Agricultural Trade Policy Simulation Model (ATPSM) is designed of detailed analysis of agricultural policy issues. It can be used as a tool by researchers and negotiators alike for quantifying the economic effects at the global and regional level of recent changes in national trade policies. The Model covers 161 countries and 35 agricultural commodities, and includes an extensive database. The Model also provides estimates of changes in trade volumes, prices, government revenues and welfare indicators linked to changes in the general trade policy environment. The Model can be downloaded free from the UNCTAD website at http://www.uncatd.org/tab/.
