The study of effective factors on financial development in Iran on the Bayesian approach

Financial development is one of the important and effective factors on the countries economic development and it is considered by planners and policymakers. Financial development is a multifaceted concept that, in addition to the monetary and banking dimension, includes other dimensions such as financial freedom, quality of governance and oversight, technological advances and existing institutional capacity. So this study, identifies 16 effective variables on financial development index and ranks them using the Bayesian model averaging (BMA) in Iran during 1991-2017.Inclusion probability indicates that liquidity Ratio and Credit Risk are the most effective economic factors on Iran's financial development. Inclusion probability indicates that the size of the government, the rate of inflation, the openness of trade, the ratio of participation bonds and the size of the banking market take third to seventh rank regarding their effects on financial development model of Iran respectively. These variables have positively affected on the financial development index. Also, corruption control rank and government effectiveness rank with 44% and 36% probability of occurrence are the most effective non-economic and institutional factors in the financial development model of Iran, respectively, and affect the financial development index in a negative direction.On the other hand, there is no significant relationship between government budget deficit and financial development in Iran, due to the low probability of this variable in the model; it seems that this variable can affect financial development only through the channel of other variables included in the model.
