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
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
The impact of monetary policy on nominal and real variables in the economy is very important and controversial issues in monetary economics. Thus, the interaction between the real and monetary sectors, are the questions that different schools of economic have different responses and assumptions in this design is neutral and super-neutral of money in the long run. Accordingly, the acceptance or rejection each of the above hypotheses, effects on the role of monetary policy in the economy. This study, has been investigated the effects of monetary policy in the framework of a dynamic general equilibrium model on inflation and welfare, based on the money in utility function in Iran's economy. Then, the model is solved by using dynamic optimization and analyzed the results in the steady state. Calibration results and sensitivity analysis in steady state indicate that by decreasing the growth rate of money supply from 22% in the base state to 12%, reduces inflation rate from 20.45% to 10.57% decrease and increases real money balances from 0.1304 to 0.1352 unit, But the ratio of capital to labor, per capita production and per capita consumption do not change in the steady state. Finally, with a decrease in the rate of monetary growth and the increase in real money balances, the welfare increases in the steady state situation.

Abstract
Speculative demand in the land and housing market has a fundamental role in raising the price of land and housing and causing a diversion and invasion of the housing sector with the aim of profit. The government, by imposing a tax on rent of land and housing return, seeks to control speculation, allocate the land resources and urban housing and make money to build the urban infrastructure. In this study, optimal taxation on the return of housing capital is analyzed in the framework of a dynamic optimization model in Iran. Then, the calibration and sensitivity analysis of the macro variables was done to change the tax rate on housing capital return. Finally, using the GAMS software, the optimal path of macro variables was simulated in different scenarios during the period (2016-2040). In steady state, the results of the sensitivity analysis of macro variables indicate that by increasing the tax rate on the return of housing capital from zero to 25%, and decreasing the tax rate on the return of business capital from 25% to zero, increased the level of business capital per capita, production per capita and consumption per capita by 50.62%, 13.47% and 25.27% respectively, and decreased the level of housing capital per capita by 31.5%. Also, the results of the simulation indicate that the imposing tax on the return of housing capital at a rate of 4% compared to the current state of the economy, has led to upward the optimal path of business capital per capita, production per capita and business capital per capita and gone down housing capital in the long run during the transition period.

Abstract
Rental housing has been affected by housing prices in different periods and the growth of housing prices has reduced the purchasing power of housing applicants and increased the percentage of rented households. Therefore, any recession and boom in the housing sector has a direct impact on the housing rental market, and planning to control the rental market will not be achieved without considering the housing market. In this regard, the purpose of this study is to investigate the factors affecting housing rent based on two groups included large, small and medium cities in Iran using the Generalized moment method (GMM) in the period (2008-2018). The results show that housing rental prices in the previous period, housing prices, land leverage and real per capita income of urban households had the most positive impact on housing rents in both large and small and medium cities. Also, the impact of housing prices and rental prices in the previous period has been greater in large cities. Also, Housing bank facilities, the number of urban marriages and the real interest rate were other variables affecting the rental price of housing in urban areas.
