Abstract
Value Added Tax (VAT) as a method of tax charging with creating a new tax base broad has been interest of many countries. Also Value Added Tax in our country in order to reform the structure of tax and increasing government revenues was approved by the House after a relatively long time and in the second quarter of year 1387 was carried out. Given that this law as an experiment and for five year was carried out study of effects of this tax on macroeconomic variables is of particular importance. In this study has tried to use the analytical relationships Input-Output and production of technical coefficient matrix constant assumption of fixed economic conditions and economic variables and limiting assumptions of this study to the price effects resulting from applying VAT on cost of whole different departments to deal with the country's economy. By using of model price of input - output and applying tax rates issue of Article 12 on exemption for goods and services and ultimately applying export exemption issue of Article 13 on value added tax the price effects of each section of economy is calculated and with and with considering of share of each section from the whole output the price effects is calculated. Results show that implementation of VAT has had very low price effects.

Abstract
In this study, we designed and simulated a system dynamic model to analyze the impacts of energy intensity changes on environmental and economic indicators in Iran.
Results show that if the current situation is continued, the industrial sector energy intensity will increase from 2.67 in the base year to 2.704 at the end of planning horizon. So, the sector will consume 540 million oil barrels to create a value added equals 490627 billion Rials in 2025. Accordingly, the amount of environmental pollutants will increase from 59 million tons in the first year to 267 million tons in 2025 and social costs of producing this pollution would be equal to 67, 449 billion Rials. These findings indicate that regarding the limitation of the production and the increasing costs of energy supply in the future, the country's industrial policies should concentrate on technological changes to increase the efficiency of energy consumption. Also, results indicate that industrial energy consumption has destructive effects on the environment and society in the future and the costs in this sector will not be reversible.

Abstract
In this paper, the Expanding extraction method of Dietzenbacher & Lahr (2013) is used and in the form of Input-Output general equilibrium model. The article assesses and evaluates the importance of the energy sector and its sub-sections in the Iranian economy based on Iranian input-output table of 2017 that is updated by RAS approach. In this way, the 10% reduction in the supply of coal, crude oil and natural gas, electricity and gas consumed has been investigated in four scenarios. Additionally, in the fifth scenario, by aggregating energy subsectors into one sector, the 10% reduction in the supply of energy in interaction with 75 sectors is measured. The results of this simulated model show that by reducing the supply of energy sector, "Manufacture of coke and refined petroleum products" will drop by 9% in value. Respectively, "Transport via pipeline" and "Manufacture of chemicals and chemical products" reduced by 4% and 2% in value added

Abstract
The impacts of the tourism industry on economic growth can be divided into two categories: direct and indirect (spillover) effects. In the field of tourism, direct impacts have been the subject of many studies but the analysis of spillover effects, particularly the effects from tourism infrastructure development, have received less attention. This study, with an analytical approach and along with examining the quantitative methods and analysis of the spillover effects of various variables affecting the development of the tourism industry, has investigated these impacts for each the variables and in each province. For this purpose, it has used spatial econometric models. The results confirmed the existence of spatial fixed effects and was applied Spatial Durbin Model (based on Lagrange coefficient test). The results show a positive and significant impact of transport infrastructure variables (road, rail, air) and travel agencies on the growth of value added in the tourism industry. Investigation of the spillover effects of infrastructure variables on growth of value added has shown that, except for Accommodation services, other tourism infrastructure variables have negative spillover effects for neighboring provinces, and also have positive spillover effects for other (non-neighbor) provinces. The negative spillover effects on the tourism growth of the neighbor provinces are due to competition impact and relative stability in the number of domestic tourists, and the positive spillover effects on non-neighbor provinces are due to factors such as the development of multi-purpose trips and increased market access.

Abstract
This study seeks to examine the impact of market shocks and economic sanctions on production and value added in the industrial sector, one of the most important sectors of the economy, during period of recession and boom. For this purpose, we examine the effect of oil shocks, currency fluctuations and economic sanctions on the added value of the industrial sector during the recession and boom period, from 1974 to 2016. The results of Markov model estimation imply that the effects of shocks are asymmetric. Positive oil shocks and currency fluctuations have positive effect on value added industrial sector during the boom period and have negative effect during the recession. The results show that if Iran's economy is booming at time t, market shocks and economic sanctions will remain in the same position with a probability of 0.3864%, and if the Iranian economy If t + 1 is in a recession, it is likely to remain at 0.6791% at t + 1. While according to results of estimating the number of years in each diet, the number of prosperity years was lower than the recession period (27 recession periods vs. 14 prosperity periods) and the rate of durability was more during the recession. Another interesting point is that Inventory of capital, inflation of production, consumption of private sector and employment during the recession had a negative relationship with the added value of industry.So, about Iran economy, it seems that establishing an appropriate theoretical relationship between these important variables influenced more by fundamental changes in Political and economic conditions than government economic policies. Thus, although the role of macroeconomic policies, including monetary and fiscal policies, is essential for the growth of value added production but also providing economic security and a secure environment for investment, expansion and diversifying financial markets and institutions, and More productive engagement with the world and major trading partners, moving towards an open economy and the use of foreign investment and developing capital market regulations with the aim of transparency and stability to increase savings and investment is essential and could provide the basis for Increasing production in the manufacturing sector.
