One of the economic goals in many countries is providing favorable conditions to boost economic growth. One of the favorable conditions for increasing the production and economic growth is investment in economic infrastructures. In general, investment in economic infrastructures, boost production and economic growth through increasing the factors such as: productivity, development of market area, equilibrium between supply and demand, creating positive externality effects, making better environment for competition and increasing the welfare level. The objectives of this study are investigating the effect of investment per worker in economic infrastructures on the non-oil gross domestic production per worker and investigating the interaction of capital per worker, non-oil economic growth per worker and investment per worker in economic infrastructures. Vector autoregressive model has been used for empirical investigation during the period of 1961-2006. The empirical results of this study show that in long run the effect of investment per worker in the economic infrastructures on the non-oil gross domestic production per worker is positive and investment per worker in the communication infrastructures has the highest effect and investment per worker in energy infrastructure has the lowest effect on the non-oil domestic production per worker. Empirical results also show that in short run the relationship between non-oil economic growth per worker and investment growth per worker in the economic infrastructures is insignificant, but the effect of capital growth per worker on the non-oil economic growth per worker and investment per worker in the infrastructures is significant and positive.

This paper examines the association of income inequality and economic growth with public expenditures on education as an intermediary factor in Iran. Time series data from 1974-2005 and two stage least squares (2sls) method are used to estimate a simultaneous equation system. Public expenditures on education and economic growth are dependent variables and population density, human capital, past public expenditures on education and income inequality are considered as explanatory variables in the model. The results are as follows: 1-There is a negative association between income inequality and economic growth with or without public expenditures on education as an intermediary factor. 2-Public expenditures on education are negatively associated with economic growth. 3-Although the sign of past public expenditures on education with public expenditures as an intermediary factor is positive, but the coefficient of past public expenditures on education is not significant in the growth rate equation. So a judgement can not be made about its relationship with economic growth.
