May the pro-poor impacts of trade liberalisation vanish because of imperfect information?

Boussard J.M., Gérard F., Piketty M.G., Christensen A.K., Voituriez T.. 2004. Agricultural Economics, 31 (2-3) : p. 297-305.

In this paper, we try to evaluate changes in welfare gains and their distribution due to trade liberalisation when imperfect information is considered. The results of two versions of a computable general equilibrium (CGE) model, using GTAP database and representing goods as well as capital flows, are compared. In the first version, a standard world CGE approach is followed. In the second version we included risk aversion, imperfect information and production lag in the agricultural sector. After a brief description of the two versions, changes in welfare, represented by the income of two types of household (middle-low and middle-high) in three regions (Europe, United States, Rest of the World) after agricultural trade liberalisation are presented. Theoretical and political consequences of the results are discussed.
