ATPSM 1.0

ATPSM is a trade policy simulation model. It can be used as a tool for quantifying economic effects at the global and regional level of changes in trade policies. The user specifies a specific change in trade policy such as a tariff reduction and the model simulates the new prices and trade flows and calculates welfare effects.

ATPSM can be used as a tool by researchers and negotiators alike for quantifying the economic effects of potential changes resulting from future unilateral action by individual countries or actions required under negotiated agreements. In an increasingly integrated world, with complex links between countries and sectors, the systematic framework of ATPSM empowers policy makers and trade negotiators. The latest version of ATPSM has a graphical user interface to assist the user in setting up scenarios, running the simulations and storing and reading the output data. This and the context specific on line help make the program easy to use for everyone who does not have "extensive training in economic modelling".
