Mechanism of impact of shocks on oil prices, currency prices and investment, taking into account adjustment costs on the stock price index

The present article explains the mechanism of the effect of shocks on oil prices, currency prices and investment by considering the adjustment costs on the stock price index using SVAR structural self-regression model for the years 1370-1397. Based on SVAR model estimation results; A shock in oil prices will reduce production by 5 percent and reduce employment in the country by 1 percent. The results also show that a single impulse from the oil price range increases the stock price index by 33%, as well as an exchange rate impulse from the exchange rate increases the stock price index by 7% and an impulse from Taking into account the adjustment cost, the investment area will reduce the stock price index by 40%, as well as a shock from the commercial period and the production gap will reduce the stock price index by 17%. Also based on the results of analysis of variance among the variables of the model; Investing in adjustment costs, oil price shocks, currency shocks, real interest rate shocks and production gaps, respectively, accounted for the largest percentage of explanatory changes in the model during the period under review. Therefore, reducing investment adjustment costs by applying various policies such as; Distributing skills and supporting unemployed workers, developing technical and vocational education, reducing labor costs between industries, using trade liberalization policies can be helpful in ensuring macroeconomic stability and stock market and stock market index..
