Index trading and agricultural commodity prices: A panel Granger causality analysis  
Gunther Capelle-Blancard

This paper investigates the causality between prices and index-based trading activity for twelve grain, livestock, and other soft commodity futures markets. We use panel Granger causality estimations based on SUR systems and Wald tests with market-specific bootstrap critical values in order to take into account the possible contemporaneous dependence across markets. Our results confirm that there is no causality between index-based positions and commodity futures prices. Abstract
