Abstract :

The impact of public debt on economic growth is recognized as one of the important issues in economic analysis. . Therefore, in the present study, using the annual data of 128 selected countries and the Panel Smooth Transition Regression (PSTR) model, an attempt has been made to investigate the threshold impact of the country risk index on the impact of public debt on economic growth in four separate models over time. 2018-1996 .the findings indicate that, there is a significant nonlinear relationship between public debt and economic growth. However, the estimated models with transmission variables of political risk and composite risk in both regimes indicate that the public debt have had a positive effect on economic growth. Moreover, in the models with the transmission variables of financial risk and economic risk, the impact of the general debt on economic growth was negative and positive respectively in the first and second regime.
