1 - A Study of the Effect of Labor Force Productivity on Unemployment in Iran

One MoreUnemployment is classified as one of the most serious obstacles to economic and social progress. So to avoid the negative effects of unemployment, reducing the rate of unemployment should be considered as one of the leading development goals in developing countries. One characteristic of developing countries is the low rate of productivity growth, and the increase in productivity is the result of reducing the use of resources, reducing costs, using better methods of production or improving the ability of production factors, especially the labor-force. So, the Objective of this research is to study the effect of productivity of labor-force on unemployment in Iran from 1978 to 2010. For the theoretical analysis of the topic, ordinary least squares method was used, and the data were collected by the annual time series coefficients data. The research results of this method indicate that the impact of all variable coefficients has been expected based on the theoretical frame work, the coefficients for all variables are significant, and productivity of labor has a negative effect on unemployment.

Doing so, we have used the micro income-expenditure survey data published annually by the Statistical Center of Iran and estimated the non-parametric Gini coefficient, poverty line and then poverty gaps. Then, in order to compare the urban and rural poverty as well as inequality levels regarding Hormozgan with that of the country as a whole, we have used 6 simple regression ANOVA models. The results indicate that the urban poverty and inequality levels have been significantly lower than that of in the rural areas. Poverty in Hormozgan urban and rural areas have been significantly more than urban and rural areas of the country as a whole, respectively. However, the Inequality in Hormozgan urban and rural areas have significantly less than those in the country as a whole, respectively. Manuscript profile -

Based on the results of the model, the economic policy shock causes a sudden increase in economic growth and consumption and then their decrease; However, the economic policy shock increases air pollution. The shock of environmental policies, firstly, increases consumption and economic growth and then decreases them. Investment also decreases as a result of the shock of environmental policies. Based on the results of variance analysis, the role of economic policies for the country's economic situation and creating air pollution is greater than environmental policies. The role of environmental policies in reducing air pollution is less than the role of economic policies in increasing air pollution. It is suggested that when the government increases its expenditures, it imposes green taxes or carbon emission taxes at a lower rate than the increase in government expenditures so that the economic growth of the country will continue to be maintained along with the reduction of environmental pollution.

The results confirm the puzzle in the period. Consequently the paper introduces and proposes an experimental and theoretical model to explain equity premium through Consumption Capital Asset Pricing model in habits formation model and combination of financial and economy regimes by Fuzzy Logic. Results derived from proposed model showed that equity premium and risk aversion have a counter- cyclical relation with economic regimes; so that in recession regime and reducing market, consumption news increase relative risk aversion and equity premium. In this regime, the individual prefers to adventure only in lieu of high level of compensation and he or she also intends to allocate the funds into more certain fields such as bank deposits. While consumption news in the period of boom in economy and increasing market, decrease risk aversion and equity premium. Manuscript profile -

6 - The effect of financial indicators on economic growth in Islamic countries using a non-linear model

Countries with a more developed financial system are on the path of faster economic growth because they make the economy in question capable of experiencing higher growth rates. The main purpose of this article is to investigate the effect of financial development indicators on economic growth in member countries of the Islamic Conference; Therefore, in order to examine this topic, the present article used one of the newest econometric approaches called the PSTR model and measured the non-linear effect of financial development indicators on economic growth in the member countries of the Islamic Conference during the period from 2008 to 2022. The results obtained from the PSTR model indicate the existence of a non-linear relationship between the studied variables. In the final PSTR model, the slope parameter, which indicates the speed of adjustment from one regime to another regime, is equal to 21.0818, the location of regime change is estimated to be 10.5986. Therefore, if the financial development index (the ratio of internal credits of banks to gross domestic product) exceeds 10.5986 percent, the behavior of the variables will be according to the second regime, and if it is less than the above threshold, it will be placed in the first regime. The coefficients of the variables (percentages) have been estimated. The obtained results show that the financial development index (the ratio of internal credits of banks to gross domestic production) has a different effect on economic growth in both regimes.

7 - The Influence of Financial Development on Income Distribution in Some Selected Countries
منیره دیزجی محدثه آهنگری گرگری Abstract Since the development of institutions, agencies and financial markets of each country can have significant effects on income distribution of that country. The aim of this study is to examine the relation between the financial development and inequality More Abstract Since the development of institutions, agencies and financial markets of each country can have significant effects on income distribution of that country. The aim of this study is to examine the relation between the financial development and inequality in developed and developing countries by using generalized least square method(GLS) and generalized method of moments(GMM) and related theories, studied by entering variables like unemployment rate, the average years of schooling indices of human development, government size and per capita during the period 2000 to 2013. Thus, according to the ranking report of the United Nations Human Development(UNDP) in 2014, 35 countries with very high human development index and 32 countries with high and medium human development index have been selected as developed and developing countries, respectively, which these regions have had full data. The estimation results have been obtained using Stata14 and Eviews9. Empirical results obtained for developed countries, showed that the square of financial development is part of the descending inverted U curve. For developing countries, the estimation result of GLS approved the inverted U curve for the variables financial development and per capita income, while the GMM results income with income inequality, respectively. Finally, according to the above discussion, it can be concluded that for the developed and developing countries, the increase of financial institutions will reduce the income inequality.

8 - The Effect of Financial Development and Its Size on Economic Growth with a Nonlinear Approach in Iran
Sedigeh Dodangeh Seyyed Shamsuddin Hosseini Farhad GhaffariAbstractWhile it is economically well established that the financial sector is interrelated, empirical estimates of the growth of these textual results are generally presented.

On the other hand, it will be different for several time series assessments at different levels of economic growth and in terms of time requirements, so it seems that estimating linear models to examine macro-relationships is challenging. The aim of this study was to investigate the relationship between the development and size of the financial sector in the Iranian economy with economic growth in the years 1350-1399 using the non-linear regression method of Astana. The results show that there are three different regimes for the effect of changes in financial sector size and financial development on economic growth. In economic growth rates, only financial differences affect economic growth. This effect in the second regime, ie between the economic growth rates of 0 to 8.6%, is weak but positive and significant, and in the economic growth rate above 8%, both financial size and financial development have a positive and significant effect on economic growth.
