An application of the spatial equilibrium model to soybean production in tocantins and neighboring states in Brazil

In the production chain of soybeans in Brazil a sizable part of the corresponding cost structure is the result of logistics costs. Given the location of its production sites, distant from the ocean, the optimization of the transportation costs is essential for preserving competitiveness. Using nonli...
