Influência do preço de 3 commodities no agronegócio brasileiro: um estudo em painel

Abstract

Agribusiness is an important source for the national economy, being one of the main sources of financial resources for the country. The respective work aims to identify if the price of commodity exports influences the total exported and imported. It is considered the figures used by Aliceweb database MDIC, using annual data from the years 2000 to 2016. The data were analyzed through annual panel data, in which the variables (unit root test, multicollinearity, normality, heteroscedasticity and autocorrelation) were analyzed for multiple regression. The explanatory variables have a positive significance of 5% only VPB and VPS variable, both in exports and imports also showing also that even with a higher average VPM variable does not have a 5% significance level. It is concluded that among the explanatory variables, even the one that contains the highest export average, does not have total influence for both export and import, this may be due to other factors that were not analyzed in the study.
