This study is concerned with the relationship between the Iranian Oil Industry and Iranian economy. Oil revenues have been the largest source for financing economic development plans and for obtaining foreign exchange. In this paper, the history of the Iranian oil industry is summarized, and five previously implemented developmental plans are analyzed. Additionally, the impact of oil on some economic sectors and its contribution to GNP is examined. The strong correlation between oil reserves and the economy may bring a problem in the future when oil reserves run out. Iranian economists believe that the economy must be industrialized in order to reduce the economy's reliance on oil. This paper recommends that all the economic sectors, particularly agriculture, should receive careful consideration, even though the national goal is to industrialize the economy.

The purpose of this study is to analyze the system of personal income taxation in Nigeria, especially with respect to its administration, equity, and effects on efficient resource usage. There have, in the past, been numerous complaints that the personal income tax in Nigeria does not yield enough revenue for the state governments, primarily because of widespread avoidance and evasion of the tax, especially by persons who do not derive income from wages and salaries. This study examines this problem in light of questions as to how the tax evolved, how important it is to state governments, how efficient and equitable it is, what administrative problems it faces, and what reforms can be implemented to best solve existing problems.
