Trade barriers can be divide in two forms of Tariff and non-tariff barriers. Which non-tariff barriers are low transparent and cause more restricting effects. Since Iran is about to join the world trade organization (WTO), it is necessary to evaluate the effects of these barriers on Iran’s trade flow. Due to the growing global demand for industrial goods, in this study the effects of trade barriers on export and import of manufacturing industries have been tried to evaluate. For this purpose, by providing a theoretical framework, first by using of Johanson – Juselius method long-term relationship of import demand and the supply of industrial exports of Iran in the period of (1359-1389) (1978-2010) are estimated. And then by using of error correction model, short-term relationship of import demand and the supply of industrial exports of Iran in the same period are estimated too. The result show that in the long term. Tariff and non-tariff barriers effect on Iran’s industrial trade. However, in the short-term these barriers have no effects on the import and export sector of Iran’s industry.Although free trade will leads to development of comparative advantages, increases efficiency of production factors and creates wealth in the society, but trade barriers remain to use, partially in developing countries.

Therefore, after a brief discussion of the CIA model is a perfect representation of the model. Finally, the model is calibrated for the economy and the results of the calibration is the following:
In the short-term and emergency situation the government needs to finance its budget deficit, welfare cost of finance through seigniorage tax less than the cost of finance welfare through consumption taxes. Long-term and stable situation, seigniorage tax replacement strategy rather than consumption taxes impose costs on society's welfare.This study using the CIA model to compare the welfare cost of seigniorage tax and consumption tax for the Iranian economy.

The required data for the period 2003-2013 has been extracted from official and credible sources and model is estimated using the panel data technique, The poverty headcount ratio selected as the dependent variable and ICT variables such as the infrastructure sector including fixed and mobile phone subscribers the spending on hardware and software and benefit sector including broadband Internet subscribers and the percentage of people who use the Internet, as well as, the control variables including the Gini coefficient , inflation rate, the globalization index and corruption index has selected as explanatory variables. The results show that the net effect of ICT variables has a negative effect on poverty indicator and the final effect of ICT variables depend on complementary factors. This means that educational expenditures per capita and GDP per capita accelerate the impact of ICT on poverty. Control variables including corruption index and globalization index and inflation index have a negative and significant impact and Health expenditure per capita variable and index of GINI have a positive and significant impact on poverty.The main purpose of this paper is to examine the impact of different aspects of ICT on poverty in selected middle-income countries.

The FDI has direct and indirect channels on health in host country. In direct channel, if the foreign firm paid high wage to labor forces and provided them by social services, then the health of host country improves. In indirect channel, the FDI increases the income of host country then this effect increases the demand for health services and finally it improves the public health. The object of this paper is the analysis of FDI impact on public health in OPEC countries. We used the DOLS method for panel data in the period of 1980-2013. The results show the FDI and other factors include economic, environmental and social factors have significant and positive long-run effects on public health in these countries. Therefore, the FDI attraction is an important factor in improving of health in OPEC countries. The Foreign Direct Investment (FDI) is an effective factor on health in host country.

Therefore, Diewert-Fox model and Törnqvist index and the data of 23 selected manufacturing industrial sectors during 1997-2010 are used. The results show that most of the selected sectors have increasing returns to scale and based on these results, there is potential of efficiency improvements in manufacturing industries. Furthermore, most of these industries experience significant technical change which implies that the growth of manufacturing industries has been driven by both increasing returns to scale and technical progress.It is the purpose of this paper to evaluate and compare the return to scale and technical change of manufacturing sector subsections of Iran.
