This paper considers the complete feature of commodity spot prices for risk measuring. We use a Double-Exponential Jump model to capture the evolution of wheat spot prices from 2004 to 2014 and utilize the estimated model in the calculation of Value-at-Risk. In the modeling of wheat spot prices, the baseline model outperforms all alternative models. In the case of relative high volatile period, there exists risk underestimation of Value-at-Risk with normal distribution hypothesis. It is suggested to take into account jump risk and other special characteristics of prices in the risk management for agricultural cooperatives. |
