Abstract
This paper investigates the relationship between real exchange rate uncertainty and stock price index in Tehran stock exchange for the period of 1995-2009 by using monthly data and applying Bivariate Generalized Autoregressive Conditional Heteroskedasticity model (Bivariate GARCH). The results show that there is a negative and significant relationship between real exchange rate uncertainty and stock price index. However, the relationship between stock price uncertainty and real exchange rate is insignificant. Therefore, our results recommend that the policies which cause more volatility in the exchange market and also more volatility in the real exchange rate should be avoided to ensure the sustainable growth of the stock market and its price index.

Abstract
Changes infertility ratesasone of the factors affecting the demographic changes and its rolein the labor supply and there fore economic growth, as an important element ofsocio-economic development of every country is considered. So that the importance of demographic changes in each country in recent years has increased resulting aging population in general and specifically decreased fertility that increased concerns for the global economy and the majority of developing countries-including Iran. However, the range of empirical studies in incurred countries is very limited and in most studies, the surface shape of the subject has investigated in a simple line a reconometric model. Thus this study investigates the impact of fertility’s changes one conomic well-being in selected MENAcountries over the 1970-2010. We apply dynamic consumer optimization model that incorporates end ogenous fertility as well as end ogenous education and health investments offered by Prettner and et al. (2013). The estimation results of non-linear panel smooth transition regression model reports the negative effect of fertility and positive effect of revenue and population on effective labor force, which show that the quantity-quality trade off in population acts in favor of labor force and increases its quality and causes output growth and well-being. This issue is in ferable from positive effect of population on education and health-as delineator indices for well-being- in the countries under investigation.

Abstract
The present article studies the interactive relationships between oil price volatility and industries stocks of basic metals, petroleum and chemical products by using Vector Auto Regressive (VAR) and Multivariate Generalized Autoregressive Conditional Heteroskedastisity (GARCH) models from March 2004 to March 2015 empirically . In this research, the VAR-GARCH model is proposed, which is developed by Ling and McAleer (2003). The model survives the return and volatility problems among the considered series and this is the VAR-GARCH advantage. The results show that there are Average effects between oil market and stocks market of basic metals and petroleum products, But this effects are not true for chemical industry market. The volatility effects between world oil price and chemical and basic metals industry markets is not existed, but between oil market volatility and petroleum products stock volatility, Significant negative relationship is existed. There for, the investors should reduce their portfolios basket dependences on oil price as much as possible.

Abstract
There is a situation that due to economic shocks and imbalances in structural budgets and its continuation leads to stress in governments in uncertainty conditions. Fiscal stress as a volatile situation in financing of local governments can exacerbate the inability of governments to meet short-term and long-term fiscal commitments and excessive dependence on the central government. So the positive and negative effects of stress are related to the actions and responses of central and local governments. It is essential that policymakers in central and local governments pay attention to accurate and timely signs of fiscal stress for respond to stresses effects. In this study, we tried to clarify the fiscal situation in 31 provinces of Iran by calculating the local fiscal stress index from variables of fiscal structure and budget of each province and then estimate the threshold and spatial effects of the index through Panel Smooth Transition Regression method on economic growth and employment over the period 2005-2017. The results show that border provinces have the highest stress among other provinces, and provinces located in the center or near the capital have less stress. These results indicate the high centralism that exists in the provinces of Iran and has hindered the fiscal independence of local governments so that they can control and regulate their own revenues and expenditures, and in this case, they suffer less fiscal pressure and stress.
