NAIRU plays an important role in guiding monetary policy to control inflation and unemployment. The purpose of this paper is to estimate the so-called “Non- Accelerating Inflation Rate of Unemployment” (NAIRU) in Iran. In this paper, different filters such as Kalman, Hodrick-Perescott and Band-Pass have been used during 1348-1388 (1969-2009). Also, The NAIRU estimations under the above different filters were compared to the actual rate of unemployment. Our findings indicate that the Kalman filter is more consistent with the performance of the Iranian economy. The average NAIRU estimated under Kalman filter was about %10.8 during the period. Using suitable monetary policy can reduce the so-called unemployment gap measuring the deviation between NAIRU and the actual unemployment rate.

In recent centuries, many surveys have been done about money demand function and the variables which affect it, in developed and developing countries. As far as knowing this function accurately, it helps economic planners to adopt suitable monetary and fiscal policies, in order to achieve economic ends. Besides the known variables which estimate the money demand function, Gini coefficient variable can be used as income distribution variable in this function. In this article, the effect of Gini coefficient on money demand has been studied and evaluated. Also autoregressive distributed lag method (ARDL) and the annual data of 1999-2004 have been used. The results show that real money balance according to limited and wide money definition is cointegration with gross domestic product, rate of inflation and foreign exchange rate. And sign of Gini coefficient theoretically is not correct. To study short-run analysis of long-run equilibrium the error correction model was used, and the error correction term coefficient shows that, moving towards long-run equilibrium is slow in money market. The stability tests results show the stability of money demand function coefficients. In other words we can accept that money demand function is stable in Iran.

The purpose of the present paper is to investigate the revenue impact generating from substitution of Value Added Tax for current corporations tax of economic units in The Mazandaran Province. According to the province Bureau of Tax, in 2004, there were 19576 corporations file tax of which only 7856 were subjected to tax. Present study used a random sample of 365 corporations from different cities in the province of which the necessary data for 357 of them could be collected. Also due to the vast differences between the performances of corporations and economic units in the province, the statistical analysis were performed in five different scenarios. Our findings based on regression models and also the mean difference test for current tax and value added tax using the SPSS statistical package indicate that the current corporations tax is not proportionally varied with their value added in the province. We have also shown that the revenue generating feature of the value added tax is fully doubtful at 7 percent rate. Therefore, an appropriate rate of 10 percent which most countries around the World proposed when VAT introduced, has been suggested.
