The purpose of this paper is to investigate the interrelationships between transportation (rail and air), economic growth and carbon dioxide emissions in Iran during the period 1362-1397 using time series data and the system of simultaneous equation approach. The findings show a positive correlation between transportation (rail and air) and economic growth, as well as between transportation (rail and air) and carbon dioxide emissions. Another finding of this study is that economic growth has a significant effect on increasing carbon dioxide emissions, but increasing carbon dioxide emissions has no effect on economic growth. Based on the results, the creation and development of infrastructure related to the type of transportation in order to improve the country's economic growth is proposed.

The purpose of this study is to investigate the impact of financial development on efficiency of monetary policy in Iran during 1979-2020. The ratio of banks' domestic credit to GDP was considered as an indicator of financial development based on banking sector and ratio of the value of stock market transactions to GDP was considered as an indicator of financial development based on the capital market. In this regard, 4 models were introduced to achieve research objectives and were estimated using the Kalman-Filter approach. The results of estimating the first two models of the research showed that with improvement of financial development indicators, the efficiency of monetary policy in influencing economic growth will decrease. The results of estimating the third and fourth models of the study also showed that effect of financial development indicators on efficiency of monetary policy in impact on inflation has been negative and statistically significant, meaning that with improvement of financial development indicators in country, monetary policies will lead to lower inflation.
