The paper focuses on regional trade agreements and economic co-operation and develops a new appropriate approach to study their impact on growth and trade. The approach is based on an endogenous trade-growth theory and novelly specified in an economic integration (expenditure) framework which is the conceptual foundation of regional trade agreements. Importantly, it also appropriately takes into account major add- and sub-factors as recommended by Johansen, the computable general equilibrium pioneer, in practical economic planning and policy modelling. Applications of the approach to China, a key member of the Regional Comprehensive Economic Partnership agreement group, are also reported to provide useful insights for suitable evidence-based impact analysis. The analysis has relevance to such trading blocs as BRICS and the 21-member Indian Ocean Rim Association where Iran is a key member. Policy implications from the findings are then briefly discussed.

It seems that paying attention to social responsibility by companies can lead to a better stakeholder’s view toward the company, thereby increasing their loyalty and trust. Having the ability to obtain more financial resources in times of crisis, due to the greater loyalty of investors, will result in reducing the company risk. In contrast, being overconfident about the loyalty of individuals to the company can lead to keeping a short-term debt structure, thereby increasing the risk of obtaining financial resources. Recently, the negative impacts of petrochemical companies on the environment have made social and environmental groups focus more on this industry, and this focus has pushed companies into involving in more social activities. Considering the potential impact of CSR on the company’s risk, this study examines the relationship between corporate social responsibility and value at risk in petrochemical industry using a sample of 27 companies listed on the Tehran Stock Exchange during the 2010-2017 period. Eviews 10 is used for computing and analyzing the data, and the generalized auto regressive conditional heteroskedasticity (GARCH) model is employed to estimate value at risk. The results indicate a negative and statistically significant relationship between corporate social responsibilities and company value at risk. <strong> </strong>  

  One of the main problems of SMEs is how to finance their investments. The role of banks in this regard is crucial, since they can be a type of sources of financing through lending credits directly to SMEs. The key role of the paper thus relies on analyzing the effect of SMEs financing by the Iranian banking system.   The objective of this paper is to determine the influence of loans demanded by the SMEs on finance performance of the various Iranian banks. In addition, it studies the role of other important characters related to lending, bank efficiency, and economic performance in finance to SMEs through the banking system.   It is motivated by the hypothesis that macroeconomic-cyclical indicators and bank-specific variables influence the nonperforming loans in the banking system. This is carried out by an application to a logit model. Our findings indicate that several variables have significant effects on nonperforming loans in the Iranian banking system . Return of asset, equity return, SME loan to total loan ratio, inflation, current asset to current liabilities ratio, total SMEs€™ loans to total liabilities ratio and total SMEs€™ loans to total assets ratio have the pronounced significant impacts on nonperforming loans of the Iranian banking . The coefficient of loans to SMEs is significantly positive, which implies that a loan to SMEs increases nonperforming loans method while raising risks to the banking system.
