        1 - Modeling the Effects of Indirect Taxes on the Welfare of Income Deciles in Iran with the Computable General Equilibrium Application

        After oil revenues, taxes are the second and most important source of government expenditure in Iran's economy. On the other hand, considering the importance of social justice as one of the main goals of the government, the effects of imposing taxes on households are also very important. Therefore, this research, using a calculable general equilibrium model, seeks to investigate the welfare effects of imposing indirect taxes on different income deciles in Iran. For this purpose, two scenarios have been applied and the reactions of households with different income deciles to these scenarios have been investigated. In the first scenario, a uniform tax was imposed on all goods and services at a rate of five percent and in the second scenario, a tax on food at a zero rate, a tax on some luxury goods at a rate of 14 pecent and a tax on other goods at the same rate of 5 percent. EV index was also used to measure welfare. The results of the model show that the imposition of indirect taxes in the first scenario worsens the welfare of low-income households, while the second scenario improves the welfare of poor households and worsens the welfare of rich households. However, in the first scenario, the GDP was higher than in the second scenario. Therefore, it is recommended to choose a tax policy using an integrated tax system, we will see efficiency and economic justice. Manuscript profile

        Abstract The purpose of this paper is to consider the effects of green taxes on health costs in Iran. Accordingly, to achieve this goal, a computable general equilibrium model was used taking into account the interactions between energy, economy, environment and health sectors simultaneously. The model was calibrated with data from the Social Accounting Matrix of 2011 and the endogenous variables of the model were calculated using the GAMS software using MCP technique. The results showed that by increasing the green tax rates, the health costs caused by the reduction of air pollution would be significantly reduced. Also, the financial impact on health indicators included mortality, morbidity and non-health effects of air pollution were estimated 62, 26.4 and 11.6 percent, respectively. Based on the results, implementation of green taxes can be reduced the health costs of air pollution. Manuscript profile

        Abstract The study of the Heckscher-Ohlin theory is crucial for countries seeking comparative advantage, taking into account the production methods and technology of these countries. Iran also needs to develop a model for the production and export of goods, as well as imports of materials and goods, in order to develop and develop its trade relations with Germany. To achieve this, the effect of the relative abundance of labor and capital on the exports of both countries of Iran and Germany is studied in the form of a computable general equilibrium model and the use of the GTAP software. The results of various scenarios show that in the sectors of agriculture, industry and mining, services and oil and gas, which indicate the sectors of oil and non-oil exports in the economy of Iran and Germany, exports of services and industry and mining sectors, respectively, have the greatest effect on economic growth of both Country has Accordingly, it is proposed to accelerate the economic growth in both countries by focusing on strengthening non-oil exports, with emphasis on industrial and service exports.

        In this study, the effect of the crisis transfer mechanism (with emphasis on the 2008 financial crisis and oil prices) is first investigated. Representative of the effect of this mechanism (oil price known as a factor in the mechanism for transmitting crisis) Identify and how it affects the selected index of the stock exchange, including banks, petroleum products, metal ores, cars with daily data from 2003- 07-05 to 2021-03-17 Modeling with the possibility of regime change (MS-VAR) has been modeled using the common probability distribution of the yield of selected indices and the self-regression vector model. Then, using the causality method, despite the regime change, we examine the oil causality on the selected indices of the stock exchange, whether the causality is one-way or two-way. The results show that the zero regime is more stable than the one regime and the tendency to stay in this regime is higher and the causality is from the oil side to the selected indicators and not vice versa.
