This study aims at exploring the relationship between energy consumption/efficiency and production growth in manufacturing agencies producing transportation vehicles in 1995-2009 using Granjer, Hsiao’s Granger, Toda-Yamamoto causality and DPD approach. The results of the model show that in these companies there is a one-tailed causal correlation between production value and energy consumption/efficiency and the given correlation is verified in both of the causal approaches. Similarly, the estimation of the model using DPD approach shows that there is a significant positive correlation between energy consumption and the value of the product in big factories producing transportation vehicles. The results also show that compared with an increase in the employment rate or energy consumption/efficiency, an increase in investment in these factories has a more significant effect on the value of the products in these agencies. This indicates that changes in production technology from labor or energy intensive to investment can lead to an increase in the value of products in agencies producing transportation vehicles in Iran.

This paper examines the relationship between control of corruption and globalization (with various aspects) on economic growth in countries with high per capita income, middle per capita income, and low per capita income over the period (2002-2010) using panel data from113 different countries. According to the results of the various models, there is an inverted U relationship between control of corruption and economic growth. Moreover, the relationship between economic globalization and economic growth in countries with low per capita income is negative and significant. Also, social globalization in these countries has a negative impact on economic growth. However, overall index of globalization and political globalization has a positive impact on economic growth in these countries. Furthermore, in countries with high per capita income and middle per capita income, the impact of the three indicators of globalization (economic, social and political) and the overall index of globalization on economic growth is positive and significant.
