Resumo
This work has the objective to analyze the influence of variations in the national and international income, the U.S. dollar and the rainfall on the prices received by producers of cattle in the state of São Paulo during the period from January 2003 to December 2015. The method used to evaluate the impacts was the Auto Regressive Integrated Moving Averages (ARIMA) model, developed by Box and Jenkins (1976) and transfer functions, which capture the elasticity of changes in explanatory variables on the variable of interest and the lag in that the effect occurs. The results show that there exists an influence, quantified using elasticity, of both internal and external factors in the variation of the price received by producers of cattle in the state of São Paulo.
