The establishment of soybean price and its interrelation with the prices of its derivatives: soybean meal and soybean oil

Abstract

The theme of this article is to analyze the influence of soy prices on its two main derivatives, soybean meal and soybean oil, and the other way around. For doing so, we used Johansen method, Granger causality tests and the impulse-response function among the three studied variables. Among the main results obtained, connections were found between the establishment of the future price and the three studied variables. It should be noted that the impacts on price fluctuation of soybean oil and meal may not be immediate on the price of soy. It might extend over a certain period, so that this change in soy price will be seen in the future, resulting from past oscillations in the two other variables.
