Sustainability of macroeconomics is one of the most important economic issues of the country in recent years. Stable economies are more resilient and less agitated while facing destructive shocks. In this paper, the impact of macroeconomic sustainability indices on the total price index of Tehran Stock Exchange (TEPIX) during the period of 2000-2016was investigated. The used methodology is Bayesian Vector Auto Regressive (BVAR) model. All Bayesian models consist of three basic components of the prior density function, the function of the righting reflex and the function of the posterior density, and various results can be obtained depending on which type of function is used in the model. The macroeconomic sustainability indicators include: the ratio of budget deficit to GDP, the misery indicator, and the ratio of the trade deficit to GDP. Finally, using the instantaneous response function, the impacts of macroeconomic sustainability indicators on the total stock price index is estimated.The results show that the budget deficit of the government has a positive effect on the total stock price index. This positive effect has been declining after three periods and loses its effect after 8 periods. The impact of misery indicator on the total stock price index is also positive which its effect decreases and vanishes after the second and eighth periods, respectively. The trade balance impact has a negligible initial effect on the total stock price index, which has been declining after the third period despite of the first increase until the second period.

This article has endeavored to study in experimental survey, the effect of Central Bank Independence (CBI) on the output and inflation fluctuations in the Iranian economy, using vector Autoregressive (VAR) econometrics method. For this purpose, we started with the changes in output and inflation stability in bringing about good economic performance, over the period 1961-2014 years. The paper has introduced a new legal combined Central Bank Independence index, by the name of "Average (Mean) Index". According to the 40% amount of total on the base of this new index, it has been cleared that there was independence just during 1340-1361 period. The results of Generalized Autoregressive Conditional Heteroskedasticity (GARCH) method indicated that the inflation and output variances trends were approximately inverse over this period, except in some short periods. The estimation of study model revealed the negative and significant of Central Bank Independence effect on output and inflation variances. It means an increase in Central Bank Independence will cause decreasing their fluctuations and will results more macroeconomic stability and better economic performance. According to the result of Variance Decomposition and analysis of Impulse- Response Functions, the positive impact of central bank independence on macroeconomic stability has been confirmed, but it was much more effective on the nominal sector and shrinking the inflation uncertainty than real sector and output instability.
