Symmetric and Asymmetric Models of Oil Demand by Major Consumers of Iranian Oil

The present paper attempts to analyze, from statistical point of view, the asymmetric model of oil demand by major consumers of Iranian oil such as apan, China, India and South Korea through estimating their oil demand function. In this analysis, the decomposition model of price was used and finally a comparison between symmetrical and asymmetrical patterns was drawn. The results obtained from the analysis ve ify the hypothesis in such countries as Japan, India and china. However, as for South Korea the statistic data could not nullify the theory of equivalence coefficient which verifies the reversible model. The analysis of price elasticity showed the inelasticity of demand in these countries. Therefore, it is expected that increase in demand for oil in these Countries to continue at least for a short period of time since such factors as increasing population, commerce and economic growth is evident in these countries, particularly in India and China.
