The unstable state of macroeconomic indicators such as gross domestic product (GDP), investment, and inflation rate, as well as the disproportionate level of high volume of cash held by private individuals versus the low volume of liquidity in manufacturing firms, have always been a significant problem in Iran's economy. In this respect, the relationship among the stock market, bank deposits, and speculation in the foreign exchange market, and also, the central bank's role in directing liquidity between them to affect the macroeconomic indicators are important. The current study evaluates this subject for 1988–2018 using a system of simultaneous equations and the three-stage least squares (3SLS) method. The findings indicate that there has been a significant negative relationship among the stock market, bank deposits, and foreign exchange speculation. The stock market and bank deposits have had a significant positive effect on investment and GDP, and in contrast, foreign exchange speculation has shown a significant negative impact. Conversely, bank deposits have negatively impacted the consumer price index (CPI), whereas foreign exchange speculation has shown a substantial direct effect. Finally, despite the existence of a significant negative relationship between three financial markets in the Iranian economy confirmed by the obtained results, the central bank has forfeited a considerable portion of its potential effectiveness in directing liquidity between parallel financial markets to affect nominal and real economic indicators due to interest rate repression.

Since moral hazard in behaviors of banking system may jeopardize efficiency of debt mechanisms to fund rising, it is important to examine the empirical and theoretical evidences of moral hazard in the Iranian banking system. Risky behavior of banking system is caused by the asymmetric information problems between creditors and central bank. This paper considers the simultaneous effects between changing risk and leverage that justifies existence of moral hazard in the Iranian banking system. To do so, we use dynamic panel data model for the period 2006-2019 in Iranian banking system. According to the obtained results, there is a significant positive relationship between the level of risk and leverage. This relationship implies the existence of moral hazard that can be caused unsuccessfully performance of central bank in supervision and supporting in the banking system.

The purpose of this study is to measure the effect of consumption of different kinds of energy carriers in Iran, which caused poverty and inequality in the process of economic, social and cultural development of countries. For this purpose, we use annual data from 1984 to 2010 through a simultaneous equations model using Two-Stage Least Square (2SLS) and Three-Stage Least Square (3SLS) estimators. The results indicate that the effect of various energy carriers on inequality is different. Gasoline consumption leads to inequality enhancement but natural gas and electricity consumption lead to inequality reduction. Fuel oil, kerosene and gasoil have the different effects on inequality due to different indexes of inequality. On the other hand, energy carrier consumption leads to poverty reduction and natural gas and electricity are more effective to reduce poverty. Thus, the direct effect of energy consumption on poverty is confirmed. Totally, the results indicate that the indirect effect of all energy carriers on poverty trough inequality reduction is not confirmed, though all energy carriers on economic growth has a positive effect, and the indirect effect of economic growth on poverty reduction is confirmed.
