      abstract = {The purpose of this work is to analyze the impact of the  expansion of the Brazilian winter corn crop on spot price  seasonality in different regions of the country. We used  the Bai & Perron (2003) procedure to identify structural  breaks endogenously, considering spot prices for different  regions (Cascavel-PR, ChapecóSC, Mogiana-SP, Rio Verde-GO,  and Triângulo Mineiro-MG). Within each regime identified,  harmonic parameters were obtained using the Ordinary Least  Squares (MQO) method. Results showed that, with the growth  of the winter corn crop in Brazil, the price fluctuation  started to depend to a lesser extent on its seasonal  pattern, except for Rio Verde-GO. In addition, we found  evidence that price seasonality changed in 2010s, with  lower prices during the harvest of the winter crop (May to  August) and higher prices during the planted period  (January to March). These findings should offer insights  for marketing and risk management strategies and contribute  to the design and execution of policies that aim to reduce  the variations in the income of producers.},
