Dutch diseases and technology spillover can be some of the important effects of FDI in the oil and gas (OIG) sector. The Dutch disease refers to the problems associated with negative consequences of large increases in a country's raw materials such as oil and gas. However, affecting productivity depends on the absorptive capacity or the ability to adapt foreign technology by domestic firms. If Foreign direct investment (FDI) inflow is without productivity spillover, it may have negative effects on economy, especially if the destination of FDI is sectors such as Oil and gas sector(OIG). FDI not only plays a vital role in the development of this sector, but also significantly affects the macro and micro levels. Identifying the type and extent of these effects on economy requires quantitative and empirical evaluations. Therefore, t...

We apply these methods to forecast oil consumption in Iran. For this purpose, an improved artificial neural network (ANN) structure, which is optimized by the BAT is proposed. The variables between 1980 and 2017 were used, partly for installing and testing the method. This method would be helpful in forecasting oil consumption and would provide a level playing field for checking the energy policy authority impacts on the structure of the energy sector in an economy such as Iran with high economic interventionism by the government. The result of the model shows that the findings are in close agreement with the observed data, and the performance of the method was excellent. We demonstrate that its efficiency could be a helpful and reliable tool for monitoring oil consumption.

The strength of this channel of monetary policy transmission is highly dependent on economic conditions. The level of relying on the market mechanism in the banking industry is one of the variables that influence the transmission of monetary policy through lending channel that is called banking marketization. The aim of this paper is to analyze the hypothesis that the bank lending channel of monetary policy shocks imposed by monetary authorities is influenced by marketization in the banking system or not? To answer this question have been used two indexes for banking marketization. The ratio of the deposits of non-state-owned banks to the total deposits of all sample banks is the first index and the proportion of loans to non-state-owned enterprises in the total loans of sample banks is the second index. Also multiplication between marketization index ...

In this analysis of the 12 climate variables with the use of factor analysis into three basic dimensions have become associated with variable degrees of development for the country’s 30 provinces over the 19962006 period has been used. The results of the assessment showed that the degree’s variable of development as well as related dimension to the temperature factors on the rate of net migration statistically confidence level of 99% and 95% were significant respectively. It was shown that the people of the cold weather and glacial to the warm and humid climate migrate, and also degrees of development have a positive impact on net migration.

Transfer of technology from one region to another is another factor effecting productivity. Trade is one of the channels that speeds the transfer of technology. The effect of a ten percent productivity shock, in high-tech industries of industrial countries have been tracked on economic sectors of Iran. The result show that productivity of high technology industrial sectors in Iran has increased by 3.6%, GDP has increased by 0.52%, while inflation decreased by 1.19% in the Iranian economy. The findings also include increases in real sectoral outputs and decrease in the imports.

This research aimed at finding the best way to allocate a marketing budget across these two platforms. Firstly, a comparison was made between high-ranking websites to see how PPC and SEO respectively have been applied. It was found that an investment in SEO was seldom made. Secondly, the cross-over point between expenditure on the two systems was determined in a case study. It was determined that the website traffic crossed over after around three months, and the expenditure after six months. From this point onwards SEO became more costeffective. Finally, the cost per acquisition (CPA) was determined for both PPC and SEO. Results show that the CPA for SEO was significantly lower than for PPC, in all the test cases investigated. In conclusion, a dual approach is proposed. A model was designed, which could be appli...

The analysis covers the period of 2005 to 2017.In order to examine the convergence dynamics of these financial markets; we have employed the Philips and Sul (2007) methodology, which uses a nonlinear time-varying factor model. This paper provides a comprehensive picture of the financial systems within Iran and its convergence clubs by testing the convergence of their money market with domestic credit to private sector by banks (% of GDP), deposit and lending interest rate, real interest rate, and capital market with Stocks traded, total value (% of GDP). The empirical findings show that money and stock markets of OPEC and the Shanghai group do not form a homogenous convergence club. Results show that Iran has convergence with some countries in OPEC and the Shanghai group in money and stock markets, which can be explained by their similar econom...

The manner and degree of effectiveness of industrial demand shocks on the production of different industries is aim of this article. Results of the article are as follows:
A- The positive industrial demand shocks have been effective on the production of some of the large industrial plants but they don't affect some of others.
B- The negative industrial demand shocks have not had a meaningful effect on the production of large industrial plants.
C- Industrial demand shocks have not had asymmetrical effects on the production of all industries. They have had asymmetrical effects on industries with code numbers, 16, 17, 18, 19, 20, 21, 22, 24, 28, 30, 33 and 36, but they haven't asymmetrical effects on others industries' production.
D- Intensity of the affects of industrial demand shocks is not the same in the production of different industries.
