Modeling the Causes of Credit Crunch in Iran: DSGE Approach

The financial market plays an important role in any economic system by financing the real sector. Considering the major contribution of the credit market to total financing in Iran, it is clear that inefficiencies and market risks can significantly affect the real sector. In the Iranian economy, in recent years, credit crunch has been created for many reasons. The purpose of this paper is to study the most important reasons for the credit crunch in the Iranian banking network and their effects on bank lending and macroeconomic variables. Therefore, the Iranian banking system has been tried to be organized within the framework of a dynamic stochastic general equilibrium model in order to create a new horizon for policy impact assessment. The results show that the nonperforming loan shocks is more effective in reducing credit than other shocks, and the length of time it goes away is longer.
