This study has been used to investigate the effect of oil price fluctuations on the banking system and how it is related to the macroeconomics, using the quality of bank fragility introduced by Kibritçioglu (2003) and the selection auto regression method with the Markov switching model.Since fluctuating and unstable economic conditions have an impact on economic conditions and the banking system to detect the effect of oil prices, using the variables of fragility index and oil price, currency growth rate and GDP growth rate, the vector auto regression model with Markov switching (MSH(3)-VAR(1)) and seasonal data from 2004 to 2019 have been evaluated.The results show that the oil price shock in the stable regime causes a smaller change in the value of the fragility index compared to the other two regimes, and with the increase in GDP, it improves the economic conditions and the banking system. On the other hand, in the regime with moderate risk, the oil price fluctuation causes an increase in bank fragility, but due to the effect of the oil price shock on the increase in GDP and the decrease in the exchange rate, it has the ability to become a stable regime. While the occurrence of oil price shock in a high-risk regime causes economic conditions to worsen and its reciprocal effect on the banking system.

The interaction effect between financial development, air pollution and economic growth is on of the main issues in the macroeconomics literature and has been considered empirically from the view of economics researcher. Moreover, importance of renewable energy in economic growth, reducing environmental pollution and the role of financial resources on renewable energy projects express the importance of financial development in the development of renewable energy. This paper examines the nexus between clean energy consumption, financial development and economic growth in a group of MENA countries during 1995-2018. For this purpose, the (GMM) method has been utilized for model estimation. The results show that increasing clean energy, carbon dioxide emissions and increasing foreign direct investment have boosted economic growth in the countries studied. Also, despite the positive impact of financial development on clean energy consumption, it has not been able to reduce pollution. In order to expand investment in renewable energy, projects related to this sector should have been easier and more accessible to large and basic investors. Proper financial structure can lead to an increase in the volume of investment and at the same time reduce costs. On the other hand, it should be noted that targeting for projects can play a facilitating role and lead to investment maturity. Access to effective and appropriate tools to reduce risk for private sector investment and the use of tools such as guaranteed purchase, standardized portfolio of renewable energy, quota policies and low-cost lending for renewable energy projects will be able to meet the challenges overcome existing problems and reduce project risks to a great extent.

The relationship between the economic growth and the environment quality and degradation is one of the most debated topics among the economists and environmentalists. Economic growth usually requires more consumption of energy, which leads to more environment degradation. Substituting renewable energy sources for fossil fuels would prevent environment degradation; however, it will hinder the economic growth. Therefore, the relationship between the economic growth and environment could go in both directions and previous studies have shown different results. This study uses time-frequency analysis through wavelet transforms to examine this relationship in Iran using the data from the first quarter in 1991 to the last quarter in 2016. This approach allows identifying the change in the relationship between the variables over different time horizons. To that end, we calculate the coherence and energy of the wavelets over different time horizons using Matlab 2018a. The results show that in the short-run (less than a year) and mid-run (between one and four years), economic growth is the cause of environment and an increase in the economic growth would cause environment degradation. The results from the short and medium run show that this relationship was much stronger during the periods 2012-2015 and 2009-2010. However, in the long run, there is no causality between the two variables so environment regulations would not hinder the economic growth.
