[email protected]) Abstract: The last decade has witnessed different price trajectories in the international and Chinese agricultural commodity markets. This paper compares and contrasts these dynamic patterns between markets from the perspective of price bubbles. A newly developed right-tailed unit root testing procedure is applied to detect price bubbles in the CBOT and Chinese agricultural futures market during the period 2005-2014. Results show that Chinese markets experienced less prominent speculative bubbles than the international markets for its high self-sufficiency commodities (wheat and corn), but not for low self-sufficiency commodities (soybean). The difference in price behavior is attributed to differences in market intelligence, and to Chinese agricultural policies related to trade as well as domestic government policies. Besides, it discusses challenges to the sustainability of the stable price trajectory in Chinese markets.
