In Mexico, the production of oilseeds is an important economic activity. During 2016 it contributed with 0.6% from GDP of national agriculture. In terms of surface sown in 2014, it represented 4% of the country's agricultural area with 891,943.2 hectares, contributing with a production value of $14, 806,998.0. Take in account that oilseeds are the main raw material for the edible oils industries, soaps and oilseeds pastes.In this work, for five oilseeds, the marshallian and hicksian elasticities of demand were estimated with the intention of glimpsing a possible effect of a depreciation of the Mexican peso against the dollar. For that, it was used a model of Almost Ideal Demand System (AIDS) to analyze the spending of oilseeds through of price and expenditure elasticities, both compensated and not compensated ones. According to the results of own price elasticities, cotton (ε = -0.18), copra (ε = -0.15), safflower (ε = -0.75), and sunflower (ε = -0.21) revealed have inelastic demands, while soybean demand was elastic (ε = -1.21). In addition, cross-price elasticity coefficients showed that safflower (𝜀𝑥𝑦=0.01) and sunflower (𝜀𝑥𝑦=0.06) behave as substitutes for soybeans.
