The Estimation of Consumption Function in Iranʹs Economy

This survey tries to estimate the consumption function in iranʹs economy with the purpose of deriving the long-run and short-run marginal propensities to consumption. In this study, the annual frequency of data in the range of 1991- 2003 is used, and the ARDL method is employed to run the model. The results indicate that long-run and short-run marginal propensities to consumption from disposable income, are 0.49 and 0.39. It means that one percent increase in disposable income leads to 0.49 and 0.39 percent increase in consumption(in the long-run and short-run, respectively). Also liquidity has a positive significant effect on private sector consumption.
