| For the full use of the theoretical development to derive three alternative specifications of the direct, inverse, and mixed demand systems, the following empirical procedure is proposed to address three issues of the identification, functional form, and comparisons among three specifications: (i) the graphical causal methods of the PC and GES algorithms are applied to obtain an empirical guidance for the specification choice among three demand specifications; (ii) the inferred specifications are estimated with the generalized functional forms, which extend the synthetic approach based on the differential functional form framework; and the statistical tests of synthetic coefficients are used to choose the best parameterizations among the Rotterdam,... |

| The recent concurrent surges of food and commodity prices renew the debate on the causal directions between producer and consumer prices. To address this issue, we utilize the stage of processing system incorporating retail stage beyond crude, intermediate, and finished processing stages of food and employ the method proposed by Toda and Yamamoto (1995) and Dolado and Lütkepohl (1996) of Granger causality tests. The overall results show that consistent with theory of derived demand, the demand-pull mechanisms coexist with the cost-push processes in 1985-2001. However, the upward cost-push pressures dominate the demand-pull mechanism through various transmission channels in 2002-2008. |
