Abstract
This study aimed to analyze the convergence of prices in the Brazilian market
for corn, using the methodology of time series analysis of Phillips and Sul (2007). The
results showed that corn prices are not converging to one common level. However,
the analysis suggested the formation of two convergence clubs, with two units cross
diverging altogether. The first, formed by markets Mogiana/SP, Cascavel/PR, Chapecó/
SC, Carazinho/SP, Rondonópolis/MT and São Paulo/SP. The second group is formed
by the markets of Campo Grande/MS, Uberlândia/MG, Maringá/PR, Ponta Grossa/
PR and Rio Verde/GO. The markets that were presented divergent: Campinas/SP and
Porto Alegre/RS.
