In this research, the role of nominal exchange rate volatility and business cycles on the banking nonperforming loans was investigated by using Markov-Switching model during 2005-2018 using seasonal data. Business cycles were extracted from GDP by using the Hodrick Prescott filter. Also, the wavelet transform model was used to extract nominal exchange rate fluctuations. The results showed that the exchange rate volatility varies in different periods of time and in longer period of time, the foreign exchange rate volatility has a greater negative and significant effect on nonperforming loans of banking network. It shows a dependence of government on banking network. Also, the impact of business cycles depends on the nonperforming loans regime. The sustainability of low regime is bigger than high regime. The results also show that the impact of value added of different sectors of economy varies in different regimes of nonperforming loans. These results indicate that banking system should take into account the value added of different sectors of economy and nonperforming loans regimes which could decrease nonperforming loans.

Analyzing the effects of energy and financial sanctions on the output gap of the economy of Iran is the aim of this study. To do so, a New-Keynesian DSGE model is used to design the structure of model. In this approach, by defining a shock, energy and financial sanctions is included into objective functions of the economic agents whereby the behavior of households in subsectors, consumption, capital accumulation and investment spending, and also the behavior of firm in production function and marginal cost are affected by energy and financial sanctions since 2011. The data in this study is quarterly for the period 1989 – 2014. To this end the output gap is computed by Kalman filter approach and other variables are filtered by Hodrick – Prescott method. Then by using Bayesian methods, the structural parameters are estimated, where, the results from MCMC Statistic, Gelman - Brooks statistic and comparing prior and posterior distribution functions indicate that the results are credible. Finally, the effects of energy and financial sanctions on the output gap and other variables have been analyzed by stochastic simulation. The results from simulation reveals that by imposing economic sanctions, investment spending, total consumption and the process of capital accumulation declines and the costs associated with output increased thereby the output gap in economy tends to increase. Moreover, from the results of variance decomposition, investment and inflation rate is more influenced by sanctions than other shocks.
