In this paper, we dealt with fiscal dominance, which is a situation in which the fiscal authority sets its expenditure and taxes without regard to any requirement of intertemporal budget balance. Therefore, the monetary authority must adjust its policies to ensure that the government budget is in balance. The existence of oil revenues for the government on the one hand and its lack of access to the financial market, on the other hand, are reasons that we can see financial repression and fiscal dominance in the economy of Iran. This paper presents forward-looking estimates of the relationship between the change in the consolidated primary deficit and the change in the monetary base. This study covers the period 1978-2017, and an autoregressive approach is applied. We conclude that using the budget data only, the existence of fiscal dominance cannot be rejected.

The stock market is influenced by other parallel markets and macroeconomic variables; such variables have impacts on the behavior of financial market players. Accordingly, this study first examines the existence of herding behavior among investors in the Tehran Stock Exchange (TSE). It then investigates the effects of exogenous economic variables on this industry-level behavior in the Tehran Stock Exchange (TSE) throughout 2008- 2018. For this purpose, 12 different industries were studied, and the results of nonlinear regression analysis showed the existence of herding behavior in all selected industries in the bearish market. However, this is not true for the bullish market. The findings also indicate that the effects of exogenous variables are not the same in different industries.

Resource-rich developing countries are forced by economic fluctuations due to international commodity price movement. One way to reduce the volatility adverse effects is to establish institutions such as Sovereign Wealth Fund. However, the way this fund is managed is important. Iran, as a resource-rich developing country, suffers from economic fluctuations. In order to manage resource revenues, National Development Fund (NDF) has been established. In this paper, using DSGE model, we examined different scenarios for managing fund resources. A scenario, without any stabilizer Fund and two different scenario for National Development Fund. In the second scenario, NDF has a role like the one in Sixth Development Plan. In the third scenario, all oil revenues are deposited to NDF and a part of the fund as much as interest rate in the OECD countries plus 70% of long run oil revenues invested in the economy. The Results indicated that the management of oil revenues by the Fund, in which the inflow of oil revenues into the economy follows the commitment, is an appropriate policy to reduce the economic fluctuations in Iran.
