- W1490605434 abstract "The purpose of this paper is to determine the relationships between agricultural inputs from 1990 to 2001. This decade was fed up on policies that could have changed the pre-existing relationship between the demands of these inputs and their respective prices. Thus, it was used the translog cost function , based on the estimation of the plots of each input in the total cost of agriculture. The estimation was implemented by the model SUR, which takes into account the residual contemporary correlation. The results point to direct price-elasticities of demand by negative factors, although only the price-elasticity of demand for labour factor statistically different from zero. By the cross-elasticities among factors work and fertilizer, there is a relationship between those of substitution, and the demand for work far more sensitive to variations in the price of fertilizers that the opposite. It appears that capital and fertilizers are complementary, a fact that can support the growth of mechanization and the use of fertilizers in agriculture, especially in the last decade. The results are, for the most part consistent with the economic theory, and describe the relationship between the demands of the main inputs used by the national agriculture, can be used in a considerable range of analyses and policy implementation." @default.
