Abstract

In this study a single – equation model have used for estimating NEWSPRINT DEMAND FUNCTION in Iran. The data are annual NEWSPRINT consumption per capita as dependent variable and national income with a lag; printing and writing paper price and real NEWSPRINT price are used as explanatory variables for the time period 1981 to 2003. Functional form of the model is a Linear Regression Model (Log-Log). After specification the model Ordinary Least squares (OLS) have used for estimation coefficients of the model. Finally the income elasticity is estimated at 0.05 level 1.82 and the value of price elasticity is estimated - 0.46. Both income and price elasticity are statistically significant at 0.05 level. In addition, statistically significant coefficient of printing paper price indicates that with increasing its price, per capita consumption of NEWSPRINT will decrease up to 0.33 percent. By this model the per capita consumption of NEWSPRINT in Iran in year 2007 is estimated 2.56±1.15 kg.
