Abstract
In recent years, with increasing of international sanctions and oil revenues falling in Iran, more attention has paid to public spending and taxes as a source of government financing. In this regard, numerous studies have focused on the issue of taxation and its role in economic development. However, the most studies in Iran analyses the role of taxes on macroeconomic variables such as economic growth, inflation and income inequality, and there is no research in the row of the changes in tax income over the business cycle. In this study, using the dynamic least squares method, short and long-run elasticity of tax bases in Iran in response to changes in GDP over the period 1973-2014 is calculated. The results shows that in the long run, the elasticity of income and corporate tax are statistically greater than one and for other tax bases are not significantly different from the unit. In the short run, elasticity of corporate tax is different from unit and other tax bases were not significantly different than unity. According to these results, it is suggested that the Iranian government should have less focusing on income and corporate tax during the recession period

Abstract
In the analysis of the stock market and its market indices, instead of estimating returns and their distributions at a given time interval, it is possible to extract optimal time to achieve a certain return. In this study, the distribution of investment horizons and optimal investment horizons through inverse gamma statistics method for the indices of automobile, sugar, pharmaceutical, financial and banks industries in Tehran Stock Exchange were extracted, analyzed and compared. The results of the research show that at the levels of access to +5 percent return, automotive, sugar , banking and financial indices have shorter horizons than the total index, while in terms of access to negative returns ,the only indicator of the drug group has a longer horizon than the total index.

Abstract
The existence of a stable source of income for the government is crucial for the financing of current and development expenditures. The major revenues of the government in Iran are derived from two sources of tax and oil revenues. Given that much of the oil revenue fluctuations are outside the control of domestic policymakers, it is better to focus on tax revenues in order to earn relatively stable revenues. However, tax revenues are also affected by cycles of boom and recession, and in terms of economic downturns, it is also difficult to earn money from this source. Thus, the solution for this problem is that the total tax revenue of the country is considered as a portfolio of income and applied to the methods of the financial economics to optimize it, in this way, an optimal combination Tax will be specified. Accordingly, in this study, by collecting information on different government revenues during the period of 1350-1396 and using the Markovitz model from two approaches to minimize risk and maximize returns, the optimal contribution of different tax bases for Iran has been calculated. The results show that the current share of the tax revenue base of the country is different from the optimal share.
