7 pages, This study aims to identify whether there is dependence between agricultural commodities traded on the Brazilian market. We used the bivariate copula method over a ten-year period to assess the extreme effects on the returns of the following commodities: soybean, wheat, Arabica coffee, and Robusta coffee. The relationship directly affects the dependence between Arabica and Robusta coffees commodities. While the relationship between wheat, Arabica and Robusta coffees, and soybean is positively dependent. Economic growth, market dynamics, and the prices of an agricultural commodity tend to increase the price of other commodities.

Available online at www.centmapress.org, Results showed that different segments of producers had distinctive purchasing behaviors. Specifically, analytic-oriented producers tended to focus on product performance and less on the relationship with suppliers when buying their inputs. They also tended to be loyal to input brands, rely less on dealers/retailers and salespeople, and they are willing to change suppliers more often than other producers. Intuitive-oriented producers valued more the relationship with the supplier and are interested in contacting the salesperson if they need a product. Balanced-oriented producers declared to be less loyal to brands, but were more stable in terms of not changing input suppliers frequently.
