The study analyzed the persistence of shocks to the seasonal time series of the price indices of selected agricultural commodities in India. The seasonal unit root test procedure proposed by Hylleberg et al. (1990) and Beaulieu and Miron (1992) were used for 10 major price indices of agriculturalÂ commodities. The study covered the period January 2000 to January 2013. Overall resultsÂ provide significant and robust evidence rejecting the presence of unit roots at all seasonal frequenciesÂ for cereals; condiments and spices; eggs, meat, and fish; pulses; and vegetables. For the rest of the commodities studied, evidence indicates that the seasonality present is partly deterministicÂ and partly stationary stochastic. These findings have important policy implications for policymakersÂ and research analysts.
