Therefore, time series of exports, imports and prices received by farmers in Brazil from January 1997 to October 2019 were used to estimate the fractional differentiation parameter Gaussian Semiparametric Estimator (GSE), based on the frequency domain Whittle Function. Brazilian rice market is persistent to external shocks, with the presence of long memory in exports, imports and prices received by farmers.  aExports  aImports  aMarket economy  aMarketing  aPrices  aRice  aArroz  aEconomia da Produção  aExportação  aImportação  aPreço1 aWANDER, A.
