Investigating the nonlinear effect of market-oriented financial development on economic growth in Iran: Markov-switching approach

Iran's economy In the last decade have faced persistent and high inflation, political risks, uncertainty, lack of transparency and economic sanctions that makes imbalances in financial markets and hampered economic growth. On the other hand economic studies show that sound and efficient financial systems, which direct capital to use it most efficiently, are beneficial to economic growth. Therefore, the relationship between financial sector development and economic growth has created considerable debate among development economists. However, there is little consensus on the impact of financial development on economic growth as well as its linear or non-linear impact. Therefore, this study, considering the indicators of the market based financial development, to investigate the nonlinear and asymmetric effect of financial market development on economic growth with the Markov-Swichning approach. The study period is 1980-2018. In order to investigate the asymmetric effects of market-based financial development, new indicators presented by the International Monetary Fund (IMF) introduced by the study by Svirydzenka (2016) were used. The results of the study showed that market-oriented of financial development have a significant effect on economic growth only in the first regime or in other words, the recession regime. Therefore, in the context of recession and volatile economic growth, the focus of government policies on the market sector and financial development has played a very effective role and can reduce and improve the inflammation in the process of economic growth. Also, the values of the obtained coefficients showed that increasing the access of financial markets has a much greater effect than increasing the depth of the financial market in improving the process of economic growth.
