The Objective of this research, is to Study the effect of government tax revenue on stock market in Iran during 1999:03 to 2008:02 l. With using auto-regressive distributed lag model the result indicate that in the long run, one percent increase in the producer price index and government construction spending, increases 4.28 and 1.99 percent in the stock price index respectively. In addition, one percent increase in the interest rate and government tax revenue, decrease 1.07 and 4.23 percent in the stock price index respectively. Also, the results based on Error Correction Model (ECM) indicate per period (per season), about 0.13 short run imbalances to achieve long run balance is adjusted.

The Underground Economy is a phenomenon that all countries have to deal with it. The researches display that the size of activities in the underground economy are fairly large as well as, these activities are the causes of most economic disturbances; therefore, its estimation is important in the tax gap realization, the effectiveness of monetary and fiscal policies, economic growth and income distribution aspects.In empirical section, we estimated first the size of the underground economic activities for Iran from 1352 to 1387 by using exploratory factor analysis. Second, we have investigated the impacts of some variables such asdirect tax burden, indirect tax burden, gross fixed capital formation, money supply, GDP, and direct tax rate of activity on the underground economy by econometric model. The empirical results indicate that underground economic are equal to 26.77 percent of GDP, respectively. The model showed that the long-run GDP growth shocks and growth of gross capital formation have a negative effect on the growth of the underground economy. And the shock of money supply growth, load growth in indirect taxes, direct taxes and the growth rate of load growth activities a positive effect on have underground economy. That among these factors, GDP growth has had the greatest influence on the underground economy.

In this research, in order to survey and assess the effects of increasing energy carriers on consumers' welfare costs in Iran, measurement indexes of welfare costs (EV,CV) and AIDS demand function has been used. Applied data including energy carriers' price (Gasoline, Kerosene, Gas Oil, Furnace Fuel Oil, and Liquefied Gas); consumption share and quantity are for the period from 1974 to 2008. Model results indicate that increasing in prices or realizing prices in according to government suggested price scenario results decreasing 16.5 % in utility level and  in order to compensating consumers' income and achieving their initial utility level, sum of RLS 510,000 should be paid annually.

Extending the insurance coverage and protection, and social security system lead to an increase in life expectancy, improving the quality of individual lives, enhancing the cultural competency of healthcare, reduction of poverty, balancing the income distribution, risk reduction, uncertainty of the labor force in the coming years (retirement), and its overall impact on various aspects of life (economic and social). Therefore, in the present study the relation between social security and human development index in Iran is investigated.  In this study, using experimental and theoretical models, based on time-series data of 1370-89, the model case is estimated. The results obtained from the estimation of the model show that the index of the ratio of the number of those insured by social security to the economically active population, and the proportion of the covered social-worker to the active population have positive and significance impact on the human development index, and as a result, approves the research hypothesis based on positive effect and significance of the social security indexes on human development in Iran. But the ratio of the pensioners to the economically active population has negative impact, and therefore the human development index rejects the research hypothesis based on positive effect of insurance coverage on HDI index.

Many economists belive that the main channel that inflation makes its harmful impacts on economy is the inflation uncertainty. Inflation uncertainty by its ex-ante and ex-post effects influences the economic agent’s real activities and hence causes serious costs on economy.The purpose of this study is to check a hypothesis in which uncertainty inflation has negative effects on Tehran stock exchange indices. The analysis is based on generalized self regressive conditional non-homologous variance models (ARCH & GAECH) in which the errors of conditional variance varies with time. In this article by using ARCH and GARCH models, we will calculate how the amount of inflation uncertainty effects on monthly Tehran stock exchange index during 1378 till 1390. The results show that the inflation rate and the product and service price index have a direct meaningful effect on Tehran stock exchange index, while inflation uncertainty has a diverse meaningful effect.

One of the most important factors in determining appropriate externalizing strategies of each country is export capacity and capability, and comparative advantage in production and export of certain goods. Due to the privileged situation in the Bushehr province of date production, this study sought to evaluate the comparative advantage in export an dproduction of date in the Bushehr province and its districts. Using data and information of the Ministry of Agriculture, the Customs, FAO and PC-TAS, the indices RCA‚ RSCA‚ TEI‚ SAI and LQ during the period1995-2009was paid. The results show large fluctuations in RCA and RSCA indices for Bushehr province during the period and mean no particular program for export date of this Province. Bushehr Province and districts of Tangestan‚ Dashtestan‚ Deilam and Genaveh have a comparative advantage but districts of Kangan and Jam lacking advantages in the production of date. Then with concentration ratio and the Herfindahl-Hirschman Index export market structure of date and its changes during the period 2005-2009 studied. Results showed that in that period the competition in export market for Iran's date is associated with higher degrees. Finally, using screening techniques 20 countries were chosen as the most appropriate target markets and were prioritizedas potential export.

Nowdays e-banking activities of financial institutions and banks, has increased dramatically.In this paper, using data envelopment analysis to evaluate the performance of 18 public and private banks on the basis of electronic services and their performance, cladding input oriented CCR (Charnes, Cooper, Rhodes) model using the constant return to scale was determined. Studies scale efficiency and calculation at the end of fiscal year 1389 indicate that banks are Refah, Saman, Melli, Pasargad, Sina, Sarmayeh, Saderat, Tejarat, Sepah, Parsiyan, Mellat, Maskan, Keshavarzi and Eqtesade Novin without have any scale efficiency. Also the Export Development bank, Karafarin bank, Post bank and bank of Industry and Mine, have been identified as effective banks and among these four efficient banks, by using Anderson-Peterson method the Export Development bank has been detected in 89 years as the leading bank in electronic services.

The aim of this paper is to identify the rehabilitation factors in Golstan province.

We have chosen 1278 files as sample survey from government welfare organization in Golestan province. With using Logit model the result show that the most important factors to influence on rehabilitation is supporting skills by government welfare organazations.
