Abstract
For the biofuel markets and related commodities, we study their price transmission, which is in fact equivalent to studying price cross-elasticities. Importantly, we focus on the price dependence of the non-linear price transmission mechanism.
We discuss several methodological caveats. Specifically, we combine the memory robust feasible generalized least squares estimation with two-stage least squares to control for endogenity bias and inconsistency.
We find that both ethanol and biodiesel prices are responsive to their production factors (ethanol to corn, and biodiesel to German diesel). The strength of transmission between both significant pairs increased remarkably during the food crisis of 2007/2008.
