The main objective of this study can be served as an investigation and identification of the interactions of SE with economic growth and it's dependence on the level of economic growth and development .In this way, in order to design hypothesis and research's models , according to the theoretical approaches an Inverted-U functional form has been considered which is called as the Kuznets's relation To test our hypothesis , the econometric panel-data approach is employed for the period of 1999 to 2007 in two blocks of 25 countries containing high-developed and developing countries (including I.R.IRAN) under various assumptions about simultaneity problem. The results of estimations and Turning-Points calculations indicate that our two hypothesis cannot be rejected and there is a significant Kuznets's U-inverted relation between SE and economic growth . Furthermore, the relationship between SE and economic growth depends on the level of development.Other findings show that all 25 developing countries including I.R.IRAN, during 1999-2007 are in upward phase of the inverted-U curve and the neoclassical view about complementary relation between SE and economic growth cannot be rejected Manuscript profile -

There is a large gap between natural and nominal rate of unemployment in Iran. In the recent years, the policy makers tried to decrease and control unemployment rate by undertaking monetary policies, but the outcome of such policies has increased the inflation rate significantly especially during 1979 up to 2009 .In this paper, we tested the relationship between inflation and unemployment rates based on Philip’s curve hypothesis. Our estimation in form of two models separately, shows that, there is significant relationship between inflation wage rates in current period with previous one. In addition, the rate of inflation in each period is a function of productions level and wage rate. Also, the previous level of inflation has influenced current level of inflation rate significantly.
