Abstract: Temporary and permanent income shocks are the most important determinants of household’s consumption. According to Friedman's permanent income hypothesis, household consumption always responds to permanent income shock more than temporary shocks. Given that these two components shock separately are unobservable, in this paper we use Blanchard-Quah method to decompose the income shocks into temporary and permanent and then by applying Structural Vector Auto-regression model to identify the effect of that two shock components on household’s consumption in Iran during the 1974-2014 years. The results from the estimated model confirm the validity of the PIH in Iran. So that household consumption almost entirely explained by permanent shocks income. But it does not show sensitivity to temporary shocks.
