摘要：The main purpose of this paper is to analyze the statistical relationship among the fuel prices (oil, bioethanol) and selected food prices (corn, wheat and sugar). We conducted a series of statistical tests, starting with tests for unit roots, estimation of cointegrating relationships between price pairs, evaluating the inter-relationship among the vari-ables using Vector Error Corrections (VECM) and Impulse Response Function (IRF). The direction of causation in the variables is tested by means of Granger causality tests. According to our results, there is no cointegrating relationship between time series in the period April 2005 ¨C July 2008 w hile in the later period (August 2008 ¨C August 2010) there is a long run relationship among all of the variables
