Then, using applied time series models, the direction and intensity of transmission of shocks in soybean prices on prices to the retail market of products that use the oilseeds by-products as input. The products considered in the analysis were chicken meat, pork meat, beef, eggs, fish, soybean oil, margarine and biodiesel. Data from January 2000 to December 2018 are used.
