Abstract
This article seeks to modeling social welfare functions, for assessment of how distribution of transfer payment among socio-economic levels. We consider providing social welfare functions two scenarios, first the each socio-economic levels receives amount of transfer payment equal to others, and second the each socio-economic levels receives that with weighted preferences. The four basic functions determine optimal value of how distribution, and then calculate actual value of that by transforming COICOP to ISIC . Finally the difference between optimal and actual values is determined for rural and urban society and for first and second scenario. At the first scenario the difference between optimal and actual value is smaller than second and this difference at rural society is greater than urban society. The other hand the welfare distribution at the former is worse than later.

Abstract
The effect of equivalence scale on poverty line has been considered as a predetermined parameter in all previous studies about the estimation of poverty lines in Iran. As household’s members can benefit from economies of scale in consumption, the cost of reaching to a given level of welfare does not increase one to one in household scale. So the effect of household scale on poverty line as a predetermined parameter creates bias. The main purpose of this study is to estimate the poverty line regarding the household scale. The utility function and the indirect household expenditures under consumption behavior approach are estimated based on income-expenditure data for 204464 Iranian urban households during2001-2007. Then poverty lines (in nominal and real units) per household scale (1to 10 members) are calculated based on indirect household expenditures.

Abstract
Money is a facilitator of economic activities, thus, formatting of economic activity is dependent on the institutionalizing of monetary system. In common monetary system, the weakness of common perception about money, publishing and distributing mechanism led to inefficiencies in optimal allocation of resources and welfare cost of inflation tax. Partial equilibrium model in compare with general equilibrium model, underestimate welfare cost of inflation tax. Therefore, in dynamic optimization model, the equation of welfare cost of inflation tax, in addition to general equilibrium model of Lucas, derived from theoretical correction of demands for real money balances. Then welfare cost compared theoretically and experimentally in partial and general equilibrium model. Theoretical and experimental results indicate that the welfare costs of inflation tax in general equilibrium models, is an upper bound of partial equilibrium models. Also, given that the elasticity of demand for money in regard to the nominal interest rate, the welfare cost of inflation tax increases with nominal interest rate and inflation.

Abstract
Many countries all over the world will see widespread demographic changes in the decades to come. The demographic change will affect the economy and the labor market of these countries. In this paper we employ a multi-sector computable general equilibrium model to study the impacts of demographic change on the welfare, employment and activity level of economic sectors in Iran. The model includes seven economic sector and two types of labor-skilled and unskilled. We also considere the choice between leisure and work and labor mobility in the model. The model is calibrated based on the 2001 Micro consistent matrix. Results demonstrate that in the youth period, employment and activity level of sectors will increase. Furthermore, the increase in activity level will lead to an increase in income and welfare. When the population ages, on the other hand, welfare, employment and activity level of sectors will diminish.

Abstract
In this study, the effect of fare changes on commuters' motivation to change their travel time in the Tehran subway during peak hours was evaluated. A sample of 432 Tehran metro passengers who commuted between 6:30 and 9 am was studied, and their preferences were examined. The main question in this article is whether fare changes could affect passenger behavior. We evaluated fare changes and influencing factors using discrete choice models, including Probit regression models. The results indicated that commuters who received an allowance from their workplace were more willing to change their departure time. People with flexible schedules were not attracted to fare changes, as they perceived little benefits from this adjustment. The findings of this study suggest that increasing fares during the morning peak is not an effective measure. They indicate that people are more motivated when being rewarded rather than punished. Moreover, some commuters might decide to use a different mode of transportation for commuting instead of taking an earlier subway trip, which would have a negative implication for morning transportation.

Abstract
An efficient monetary and tax system plays an important role in the proper performance of the economic system, and can effect on motivation of labor, consumer, savings and investment behavior. A theory of monetary and tax reform is movement of the income tax system and inflation tax to the system of consumption tax, that can increase the tendency to savings, investment and capital accumulation. In this study, with public finance approach and using dynamic general equilibrium model with cash in advance restriction on consumption and investment, analysis the effects of reform inflation tax and consumption tax rates during the equilibrium growth path. Then, with put the amount of parameters in the steady state, sensitivity analysis of the variables to the reform of inflation tax and consumption tax rates will be discussed in the various reform program. The results of calibration and sensitivity analysis in various scenarios indicates that the reduce of inflation tax and increase the consumption tax rate, along with reducing the size of government and reduce liquidity constraints on investment, has increased capital accumulation, production, consumption, real money balances per capita and the welfare in the steady state.

Abstract
Rice is the second strategic product after wheat and one of the most widely consumed food products in the country. Population growth, consumption and growing demand, price fluctuations and welfare effects due to changes in the amount and price of rice require the attention and planning and foresight of policymakers and the country's planning system. In this study, in the framework of inverse demand system, rice types (foreign rice 1 and 2 as well as four types of domestic rice) using cross-sectional data related to consumption and expenditure of urban households during the years 96-1392 were estimated by seemingly unrelated regression estimation (SURE) method. And from 4 systems of reverse demand IADIS, IROT, INBR and ICBS Only the inverse demand system IADIS It is compatible with the data of the research method and according to the results of the statistics, the correlation ratio is superior to the other three models In order to study the welfare effects, four scenarios were defined and by compensating the compensatory and equilibrium effects and combined changes were determined. Due to the share of more than 60% of first grade foreign rice and second grade foreign rice in the expenditure share of urban households, a change in the amount of consumption of this type of rice compared to domestic rice can have a more significant impact on household welfare. The results of changing the values of different types of rice on their prices in the form of different scenarios showed that if the consumption values of imported rice decrease, the price of this rice will increase. However, the rate of price change for different types of rice is not the same, and its intensity depends on the amount of traction and the scale of each. On the other hand, the demand for different types of rice will increase in the future for various reasons, including population growth, which if this increase in demand is not accompanied by an increase in market value, will increase the price of various types of rice.

Abstract
After the victory of the Islamic Revolution and the capture of the spy nest, the West, and especially the United States, in addition to pursuing other tools, has also used the tools of sanctions and has implemented many sanctions against Iran. One type of sanctions is oil sanctions, which were imposed to force Iran to join the international community. The US and its allies' embargo on Iranian oil affects the variables of the Iranian and world economies. For this reason, a computable five-zone global trade model (GTAP) is used to calculate the implications of the game tree between the three independent actors of the United States, the European Union, and Iran. The closing of the GTAP model has been changed according to the assumptions used. The results show that the US, Iran and major oil buyers from Iran are damaged by the sanctions. This damage is exacerbated by increasing oil restrictions. With the escalation of sanctions, the European Union is also gaining negative welfare. In the Nash equilibrium, the United States and the European Union will choose weak sanctions, and Iran will try to circumvent the sanctions. Due to the economic costs of oil sanctions against Iran, the lack of full understanding between the United States and Europe, and Iran's efforts to circumvent sanctions, it seems that the United States will not be able to reduce Iran's oil exports to zero.
