The aim of this study was to The Impact of Renewable Energy Development Policies on Macroeconomic Indicators in Iran in 2020 through the exploratory mixed exploration model research method. The statistical population in the qualitative sector was professors of higher education centers in the field of energy and economics, and senior, middle managers and senior experts of the country's electricity industry and in the quantitative sector the managers and deputies of Ministry of Energy, Companies of TAVANIR, Regional Electric Company of Tehran, Fars and Mazandaran and SATBA by 180 people. In qualitative part 20 experts were selected by snowball sampling method and in quantitative part 123 people were selected by relative class sampling method with Cochran's formula. Data were analyzed in qualitative part with Delphi technique and in quantitative part with 105-item questionnaire with SPSS and Smart PLS software. To determine the validity and reliability in the qualitative part, the necessary tests including acceptability and capability have been used and in a quantitative part, the validity of the questionnaires was confirmed in terms of form, content (CVR and CVI range for each item between 0.6 to 0.1 and 0.85 to 0.1, respectively) and structure. The reliability and combined reliability of the components were estimated and confirmed between 0.847 to 0.951 and 0.759 to 0.931, respectively. Findings showed that the model of the Impact of Renewable Energy Development Policies on Macroeconomic Indicators in Iran has nine dimensions (objective evaluation, legal framework, compliance, management requirements, policy environment management, process evaluation, policy evaluators, auditing and the characteristics of the optimal method of evaluation) and 25 components.

Sustainability consists of fulfilling the needs of current generations without compromising the needs of future generations, while ensuring a balance between economic growth, environmental care and social well-being. Sustainability includes three environmental, economic and social dimensions; whose environmental dimension has a decisive weight in sustainability. Many empirical sustainability-related researches have been carried out in the 2000s and 2010s, and the empirical model used in these studies was based on the Environmental Kuznets Curve (EKC). Also, the two concepts of human development and sustainability have been widely used in development literature in the past years, and humans have been considered as an important factor in the development of different societies in various studies. Composite index of human development includes various dimensions that can affect sustainability and especially environmental sustainability. Also, the influence of large oil revenues in the oil-owning and exporting countries on human development in these countries has played a prominent role, and has categorized the countries into three groups: oil-producing countries with high human development, oil-producing countries with medium human development, and oil-producing countries with low human development. This study has used the panel data method and the Kuznets function in the period of 2010-2019 to investigate the effect of the human development index in 35 major oil exporting countries in the world. According to the result of model estimation by econometric method, environmental sustainability in these countries increases with the increase in the human development index (HDI).

One of the goals of the government is to increase the competitiveness of domestic firms to export goods and services. Moreover, the role of exports in many economic sectors has been emphasized. There are two essential requirements for developing non-oil exports: first, the presence of firms in export markets and increasing their competitiveness; second, the survival of them in international markets. This paper assesses the impact of leverage on export survival by using the data of 16 Iranian manufacturing firms from 1999-2018. These companies operate in the agricultural and food industry and are indexed in the stock exchange market. Based on Cox semi-parametric model estimation, the main result is that leverage harms export survival.

New monetary literatures widely concentrates on the importance of institutional arrangements in the effectiveness of monetary policy. The debate regarding the optimal institutional design of central banks, independence and conservatism are usually considered to be the most important ingredients for a stable and successful monetary policy. Therefore, the purpose of this study is to deal with the institutional arrangements of monetary policy especially Central Bank Independence (CBI) and Central Bank Conservatism (CBC). Indices used by Grilli et al. (1991), Cukierman (1992), Mathew (2006) and Dumiter (2009) were applied to calculate the CBI during 1961-2016, and CBC in Iran using a dynamic optimal solution under commitment in Barro-Gordon and New-Keynesian forward looking Philips Curve models. Results show that the relative concern on inflation is smaller than that on output gap for the central bank of Iran. Also results regarding the calculations of CBI based on different indices reveals the fact of insufficient independence of central bank in Iran. JEL Classification: C57, E42, E58
