| In this paper, we try to evaluate the change in welfare gains and their distribution due to trade liberalization 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 one, a standard world CGE approach is followed. In the second version we include 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 liberalization are presented.... |

| The Purposes of this paper are twofold (i) to evaluate changes in welfare gains and their distribution due to trade liberalization when imperfect labor markets are considered, (ii) to evaluate the impact of the recent reforms of the European agricultural policy on the world welfare. The results of two versions of a dynamic world computable general equilibrium (CGE) model, using the GTAP database version 6 are compared. In the first version, a standard world CGE approach is followed with perfect labor mobility across sectors. In the second version we assume that labor shifts freely within the aggregated sectors -agriculture, manufactures, services- but not across them .After a brief description of the two versions, changes in welfare, represented not only... |

| An important debate exists on whether soybean expansion in Brazil is responsible for putting more pressure on the Amazon forest or if it allows land use intensification through the recuperation of degraded pasture. In this paper, we estimate regional soybean supply own and cross price elasticity in order to better assess the possible impacts of agricultural trade liberalization in old and new soybean production basins. Applying a panel data estimation technique, we find large substitution supply elasticity between soybean and beef in Brazil Moreover, own price elasticity of soybean supply is much higher in Cerrados regions that in the South of the country. These results allow to discuss possible regional consequences of soybean trade liberalization on the... |
