Abstract Household equivalent scale is an index to measure the impact of household demographic characteristics, such as the householder’s age and gender, the number of household members, etc., and plays a significant role in measuring poverty and inequality. By taking into account demographic characteristics differences, this index facilitates the reasonable comparison of households’ welfare, and functions as a coefficient for the target household in relation to the reference household. Using income and expenditures data of Iranian urban household in the period of 2012-2018, this study measures the relative child cost of each urban household in Iran while estimating the Quadratic Almost Ideal Demand System (QAIDS) and price scaling by means of Nonlinear Seemingly Unrelated Regression. Also, it calculates the elasticity of income and price of electric power goods. The results illustrate that the relative child cost in Iranian urban households is 33% of an adult cost, and electric power goods in Iranian urban households is a necessary yet low elasticity commodity. Therefore, pricing policies may not significantly influence demand for this product.

The aim of this paper is determination of an optimal policy rule for Iranian economy from an Islamic perspective. This study draws on an Islamic instrument known as the Musharakah contract to design a dynamic stochastic general equilibrium model. In this model the interest rate is no longer considered as a monetary policy instrument and the focus is on the impact of economic shocks on the Dynamics of Macroeconomic variables. Finally, a policy rule based on Musharakah is introduced from which the optimal policy and empirical coefficients are derived. Using data from Iran, the empirical results indicate that the policy responses of central bank to output gap and inflation are in accordance with expectations and therefore, economically meaningful. So specified instrument policy rule has to be considered as optimal in general. The optimal policy rules indicate that when the authorities pay equal attention to the inflation and output gaps the minimum loss is occurred. JEL Classifications: C61, C63, E42, E52

Financial performance evaluation emerged as the great academia and business concern in the competitive world, today. In order to clarify the progress status and improvement trend of finance, it is of supreme significance to appoint a professional financial performance evaluation study for supportable progress of enterprises. This research focused on the seven important factors which represented principal effects on the financial performance of the Persian Gulf petrochemical companies. In order to achieve the research objectives, experts and engineers of 12 companies in the Persian Gulf petrochemical industry have been surveyed by sampling method, in which 180 questionnaires have been completed and the basis of the work has been used. By the confirmatory factor analysis (CFA) divergent validity of all desired factors as well as correspondent of the questionnaire were approved. To meet the research goals, non-parametric analysis demonstrated the main hypothesis of the study regarding the effectiveness of all under investigation parameters. By the Friedman ranking test, the internal processes and external environment of the organization provided the highest and the lowest rank of impact on the financial performance of the Petrochemical companies under review, respectively

This study aims to investigate the correlation between the diversification and accruals quality (AQ) in Iran’s mutual funds considering two main hypotheses and four sub-hypotheses. This research investigates the effects of cases such as beta of the company, the company's return on assets, debt ratio of company, firm's size, and accrual quality on the company's cost of capital and considers the effect of mutual funds’ diversification on decreasing information risk calculated through accruals quality in Tehran Stock Exchange (TSE) and Iran Farabourse listed companies. This research investigates 42 mutual funds from 2009 to 2013. Furthermore, the financial data of companies is considered for 20 years up to 2013 in order to calculate the accruals quality. The research results indicate that the factors such as the company's beta, the company's return on assets, and the ratio of firm's debt have direct correlation with cost of capital and this indicates that the increased risk in the form of beta and debt ratio increases the investors' expected return. However, the firm's size is inversely correlated with the cost of capital indicating that the increased firm's size provides the possibility of borrowing and bargaining at lower costs for companies. Furthermore, diversification in mutual funds results in lowering information risk caused by low accrual quality. Accordingly, the result of this research can help the mutual funds’ managers and investment companies to better manage their investments

Energy has been the main pillar of the global growth and development. Amongst various sources of energy, oil has the largest share in the global energy consumption. As these energy reserves tend to decline, few regions, most notably the Middle East which has been at the forefront with the largest reserves, can fulfill the rising global energy demand. Even then, in view of its vast energy potential, this region has attracted the attention of the growing economies of the world. This paper intends to look at one of the significant producers in the Persian Gulf energy market, Iran, and its energy relations with the Asian giant, China, from the International Relations perspective. Having a wide variety of capacities, Iran-China relations in recent years has made special dynamics, so that in different fields, this relationship has been steadily expanding and deepening. One of the most important capacity building areas in Iran-China relations is energy. The area of energy certainly has played the most important role in the dynamics of these relationships. Potential opportunities of bilateral cooperation between Iran and China in the field of energy are wide, and in case of realization it can have positive consequences of the political and security. The aim of this paper is to cover the current oil trade situation between the two countries as well as the existing problems that are limiting the growth of this relation such as international sanctions and at the end some suggestions in order to enlarge the trade between the two countries. In conclusion, we can say that a massive capacity on the basis of "energy" in relations between Iran and China have emerged that can be used to promote economic relations between the two countries in the framework of a comprehensive strategy that benefits both countries and the region. This Capacity must be accompanied with "mutual desire” to take place. Especially noteworthy is that the existing capacities should not only be considered as "energy economy" and cooperation in the field of energy, but also should be seen as the overall framework of "security" and "Asian solidarity”.  JEL Classification:  F14,  F18
