Variation and links among food and energy international prices. An analysis through VAR models from 2000 to 2012
An adequate understanding of the dynamics that characterize the agri-food market is fundamental for the development of really efficient economic policies, especially after the two recent hikes in the prices of food commodities. The econometric literature provides today advanced analysis tools such as VAR models: these models are based on a system of equations in which each variable is regressed on a set of deterministic variables, on a number of l delays related to each covariate in the model. To test the effectiveness of this analytical tool at dealing with the issues related to agrifood economy we applied a VAR analysis on prices of major food and energy commodities (oil and biodiesel) referred to the period January 2005-December 2012. Our results identified statistically significant intertemporal relationships between the price of corn, soybeans, rapeseed and oil, and suggested the direction of these relationships; we could conclude that the price of corn and soybeans are generated in the energy market only. Moreover, we used as variables the share of commodities used for the production of biofuels, and we could observe that important alterations on the food market are due to the convenience in producing ethanol and biodiesel, since the portion of the crops used for energy is in direct competition with that devoted to the feeding. This kind of models, therefore, deal adequately with datas and issues of the agri-food system and provide an analytical basis to develop economic policies that take into account the complexity of the global food system.
