The main idea of this study is examination of the Impact of Terms of Trade on
Investment by Johnsen-Juselius cointegration technique for Economy of Iran in
(1971-2006). For this aim, we specify investment function according the present
value criteria and neoclassic theory. Our model includes gross domestic production,
price index, interest rate and terms of trade.
We use Johnsen-Juselius cointegration technique for estimation of this model.
The result of econometric estimation has indicated a long run relationship among
investment, gross domestic production, price index, interest rate and terms of trade.
Our result showed GDP, price index and terms of trade have direct effect and
interest rate has inverse effect on investment.

This paper, is trying to analyse the institutional barriers of economic growth in IRAN (1959-2000). For this purpose, we have estimated a growth model with TSLS and Gregory – Hansen (1996) cointegration techniques. The results showed that, institutional qualities have positive and significant effects on economic growth. In other words, institutions play an important role in the process of economic growth in Iranian economy.

The aim of this paper is to investigate the impact of the control variables on the Iranian stock market by using optimal control theory. We try to determine the optimal path of the economic control variables like money stock, exchange rate, taxes, government expenditure and state variables such as market value of stocks and transactions during the third and fourth economic plans. The result shows that the fiscal policies has been chosen much more effective than the monetary policies. We study four different alternatives. Based on the first, second and third alternatives, the model reaches to the optimal path of the number of transactions while for the model does not reach the optimal path of the market value of stocks.
In the fourth alternative the government can reach the optimal path of its economic variables by choosing expansionary monetary and fiscal policies along with depreciation of exchange rates simultaneously.

This paper has assessed the neutrality of money in Iran’s economy by using a Computable General Equilibrium (CGE) model. Regarding this assessment, initially a computable general equilibrium was organized in which the financial market plays an essential role. Then, for the calibration of the coefficients, in addition to organizing a Social Accounting Matrix (SAM), a financial balance sheet was also provided. In this paper, the tool of reserve requirement rate is being used as instrumental variable representing monetary policy. The result of this research indicates that the monetary policies have had significant effect on Iran’s economy.
There has been a reverse relationship between the changes in reserve requirement rate and gross national product. One of the other finding of this research is that changes in monetary tool has significant effects on GNP and so money is not neutral in Iran’s economy especially when a general equilibrium type of model is being applied. For solving the model the GAMS software and Non-Linear Programming (NLP) method were used.

In this study, following Barro in an endogenous growth model, we try to determine the characteristic of an optimal economic growth. By considering two kinds of public expenditures that are: public capital and public services. The role and impacts of the regarded parameters such as time preference, depreciation rate and change in planning periods on the growth of economy is also investigated. Dynamic optimization is utilized in determination of optimal growth for Iran’s economy. For different planning periods and with various scenarios, the optimal tax and growth rates for variables such as gross national product, public capital, public services, private capital and consumption is simulated. The paper concludes a negative relation between time preference, depreciation and economic growth. It also finds a positive relation between horizons of planning periods and economic growth.

Population size and its change have enormous effects on economic growth and development. In this respect vast amounts of researches in economics are devoted to population studies. Malthus theory of population is regarded as a core in population issues, which had created a pessimistic view on population and its impact on economy, while Malthus theory were challenged by many and specially by Verlhurst, which the latter theory actually outmoded Malthus’ and gained replacement, it is wondering how in the annals of science the Verlhurst theory is forbidden and how there is a consistent acknowledgment of failed pessimistic view of Malthus on population. In this respect, this paper tries to reconsider Malthus and Neo-Malthusian views on population. And also, neglected Verlhust view from a limited institutional approach. For this purpose, the study of impact of the institutions (like authority and observance of law, economic freedom,..) and their improvements on populations receives due attention. In this research we also, in spite of recent Neo-Malthusian views, we pay attention to the positive impacts of population on economic growth. The view which in recent years gained wide acceptance and their followers are expanding rapidly in various academies, Research used method. In this study is descriptive and authors purposes a reconsideration long growth positive effects of population rather than short run negative effects in economic planning.
