the relationship between oil revenue, exchange rate, and M2 on the CPI and PPI, over time of 2005:1-2022:1, was investigated in Iran with QARDL method used. The results showed that, in the short run, all the variables had an asymmetric effect on the CPI and the PPI. oil revenues, in the long run, from the quantile of 0.05 to the median, the impact of the variable on the inflation would be increased, and then its impact would be decreased. also, in the long run, the effect of the increase on the PPI is greater than the consumer price index. In the long run, the effect of exchange rates on the CPI and the PPI was nonlinear while being symmetric. because from the quantile of 0.2 to 0.8, its effect proportionally increased and then decreased. also, regarding the M2, the results showed that this variable on the CPI and the PPI had an asymmetric effect, in the short run. in this way, from the middle quantile to the quantile of 0.9, its effect was positive and significant, and in the long run, the results confirmed its positive effect on inflation in all quantiles; although, its effect on the PPI was asymmetric.

Abstract
In this paper, the effects of oil and gold prices on stock market index are investigated. We use a cointegrated vector autoregressive Markov-switching model to examine the nonlinear properties of these three variables during the period of January 2003 - December 2014. The Markov-switching vector-equilibrium-correction ...

In this paper, the effects of oil and gold prices on stock market index are investigated. We use a cointegrated vector autoregressive Markov-switching model to examine the nonlinear properties of these three variables during the period of January 2003 - December 2014. The Markov-switching vector-equilibrium-correction model with three regimes representing "deep recession", "mild recession" and "expansion" provides a good characterization of the sample data. The results of the model show that the impact of oil price on stock returns is positive and significant in the short run. However, it has negative effects on stock market in the long run. Moreover, we find out that the relationship between gold price and stock market returns varies during the period under investigation depending on the market conditions. More specifically, the positive gold price shock decreases the stock market returns in the short run (10 months), while it increases the stock market returns in the medium and long run.
