One of the issues discussed in economy is the socioeconomic inequality in the society. Income mobility is another measure which indicates the degree of inequality of opportunity in a society. The extent of income mobility depends on socio-economic status of the individuals. Different socio-economic status leads to further inequality and increases inequality of opportunity. Such inequalities lead to the formation of Poverty which can be reproduced and transmitted from one cohort to the other, if not utilize the appropriate method. income mobility is measured as either conditional or absolute one. In Conditional mobility fixed effects are considered, however in absolute mobility it is not so. Fixed effect parameter that indicates the heterogeneity between individuals. According to the importance of the issue of poverty and the relation it has with inequality, this paper studies the conditional mobility in the economy of  Iran. In this study Household Survey Data collected by Iran Statistical Center from 1988 till 2011 is used. The method of nonlinear dynamic pseudo-panel has been used in order to measure income inequality dynamics. Nonlinear dynamics of income inequality for urban areas in Iran are estimated. This method enables us to track the performance of each cohort over time. The main results of this study indicate that the conditional income mobility is low and dine quality in the country has increased over time. Facing negative shocks, households cannot quickly improve their situation and return to the initial income, and at the same time, the market operation in itself cannot fix the problem. This means that the market provides more favorable conditions for people who have higher power and wealth. This leads the inequality to spread to the higher level.

Cigarette and tobacco products in the VAT Law is considered as one of the particular goods and in order to contorlingit’s consumption by price tools, higher tax rates than the standard rate will be levied on it. In this paper, forecasting of revenues of this tax using an approach based on the estimating of tax base has been considered. Thus the first stage, tax base (consumption expenditure) is forecasted for the period 2012 to 2015 and then tax related years by applying the tax rates, will be calculated. In this regard, Because of concerns that policy makers have access to accurate predictions of tax revenues, Supervised neural networks Method to prediction and back-propagation algorithm to train is used. The results indicate that the average annual growth of revenue from value added tax on Cigarette consumption will have 20 percent during the forecasting years.

As one of the important energy forms, natural gas consumption has an upward trend in recent years. Therefore management and planning for provision of it requires prediction of the future consumption. But many of prediction procedures are inherently stochastic therefore it is important to have better knowledge about the robustness of prediction procedures. This paper compares robustness of two prediction procedures Artificial Neural Networks as a nonlinear and ARIMA as a linear model. using resampling method to predict the monthly consumption of natural gas in the household sector. Data spans from 2001-4 to 2012-3, to train the networks, we used genetic algorithms and Particle Swarming Optimization then results were compared using 10-fold method. According to the results, the particle swarm optimization (PSO) outperforms the genetic algorithm. Then we used data from 2001-4 to 2010-3, with resampling by 2000 to predict the  natural gas consumption for the 2001 -4 to 2012-3 and to form critical values. Results show that prediction by a mixed method using ANN and PSO is more robust than ARIMA method.

Maximizing the social welfare considered as one of the main aspects the development process in society. This important is achieved through increased quality of life and welfare consumer the individual. In this context, quality of life and welfare consumer women as an important group of human resources in society, is affected by various factors. Despite women’s welfare patterns there is no precise information in this regard. Given the importance this issue, the present study using method Deaton and Paxson (1997) and life cycle model separation women heads of household expenditure as variable of welfare to three age, cohort and period effect. Therefore, in this paper, typical pattern is used pseudo-panel data. Pseudo-panel data using repeated cross-sectional data, Create generations of families during time. The feature of this method is, to trace the performance of each cohort over time. The results showed that lowest consumption is done by first generation. The age effect shows household consumption expenditure increased with increasing age. The time effect also shows Amount increase in consumption in the first decade (1991 to 2001) to more than the amount consumed in the second decade (2001 and 2011).

The inflation rate, which measured using consumer price index, can be separated into a combination of two persistent and temporary components. This separating is particularly important in analyzing inflation rate and policies to control it. In fact, without knowing the persistent component of inflation, called core inflation, quantitative targeting of inflation may not be accurate. Core inflation as a more persistent component can be measured stripping out the transitory movements in prices. The understanding of the behavior of the national core inflation rate series needs to understand provincial core inflation since the construction of the former is based on the provincial series. So, the purpose of this paper is the estimation of provincial and national core inflation in Iran. Core inflation is unobservable variable, so it estimated using Space State Model and Kalman Filter. Results show that average core inflation in all of the provinces, as well as Iran, is less than average underlying inflation. The standard deviation of core inflation in some provinces is more than underlying inflation. While core inflation in other provinces, as well as Iran, has more standard deviation as compared to underlying inflation.

The main purpose of this paper is to measure the multidimensional inequality index. To achieve this goal and answer of what trend inequality has gone through during the study period, using the data of the household expenditure income plan of the statistical center of Iran and also using the Bourguignon index, inequality was measured in several dimensions for the period 1984-2018. In addition, it should be noted that in this study, household expenditures were initially adjusted based on age composition and number of household members by calculating the equivalence scale. This adjustment was made possible by estimating the share of expenditures of different commodity groups by considering its functional form in the the quadratic almost ideal demand system (QUAIDS). Then, using data mining techniques and Principal Component Analysis(PCA), the weight of the studied dimensions in the analysis (income, education and health) was calculated and when measuring inequality, the degree of social aversion of inequality was considered in the form of two scenarios, zero and one. the results of this study indicate that the magnitude of multidimensional inequality per zero value for both the degree of social aversion of inequality parameter and the degree of substitution parameter based on the Bourguignon, index is between 0.28 and 0.41 in urban areas and between 0.26 and 0.41 in rural areas. fluctuations in the Bourguignon index and the Gini index of income have not necessarily been similar. The findings of this study also showed that the size of multidimensional inequality in rural areas is lower than urban areas in most of the years studied. There is an approximate similarity between its trend in urban and rural areas. Inequality in the 1980s was higher than in other periods (despite higher oil revenues than in the previous and subsequent periods and more government shares transferred than in previous periods), in the early 1390s, declined, and then increased again. Finally, the research findings indicate the failure of the egalitarian goals of development programs and thus emphasize the need for a fundamental review of the forthcoming programs with more attention to distribution by the market institution rather than the government.

Applying a favorable tax system has important conditions such as justice and efficiency, therefore, consumption tax and income tax will comply with the principles of benefit and ability to pay. In this regard, value added tax is known as the most important innovation of the 20th century in terms of tax collection on consumption. Since increasing government revenue is one of the important goals of imposing this type of tax, the government has tried to determine the rate of this type of tax effectively and efficiently. Disproportionate increase in value added tax rates can have negative social effects on inflation, economic growth, income distribution, and general well-being in society. It may also have disruptive effects on other variables and sectors of Iran's economy. To manage the rate increase, one approach is to simulate and examine its consequences and effects on macroeconomic variables in the form of a multi-regional calculable general equilibrium model (MRCGE). Three different scenarios were applied and examined to simulate the shock effects of the increase in the value-added tax rate (12% , 15% , and 20 %) on four macro variables of Iran's economy: inflation, gross domestic product, consumption, and investment.  The simulations were conducted at the country level using a multi-regional calculable general balance model, known as the ORANI-G Iran model, using the 2016 input-output table and regional accounts of the country. The results indicate that the effect of increasing the tax rate on value-added will increase inflation and investment and decrease GDP and consumption.
