摘要:There are w idespread beliefs that speculation with agricultural commodities on the futures market has led to rising agricultural commodity spot prices. We empirically analyse the causal relationships between spot prices of maize, wheat, rice, and soybean and agricultural commodity futures trading activities. Theoretical linkages are discussed and relationships between spot prices and financial variables are tested for Granger-causality. Hardly any empirical evidence for causal relationships have been found between changes in "volume traded" and "open positions" of futures contracts and changes in spot prices. The lack of empirical findings casts considerable doubt on the belief that speculation is a major driver of rising agricultural commodity prices
