The price volatility of agricultural crop products has increased in the last decade.

Among such models entertained in this study, ARMA(1,0)-EGARCH(3,3) with GED for wheat, ARMA(4,4)-EGARCH(2,3) with GED for bean and ARMA(1,0)-EGARCH(1,2) with student-t for pea were chosen to be the best fit models. The monthly price return series of barley exhibited no ARCH effects, and thus, was not modeled using (G)ARCH family models.
