Is the relationship between corruption, government stability and non‐performing loans non‐linear? A threshold analysis for theMENAregion
本文用面板平滑转换回归模型检验中东和北非地区银行数据，发现腐败和政府稳定对不良贷款的影响只有在超过某个门槛后才显著为负。
Abstract The purpose of this article is to check whether there is a threshold effect in the government stability, corruption and non‐performing loans (NPLs) relationship in the MENA region. To this end, we used a sample of MENA banks over the period 2004–2017. Empirical results of the panel smooth transition regression model indicate that there is a threshold effect in the government stability, corruption and NPLs relationship. More specifically, we have found that the impact of corruption and government stability on NPLs is negative and significant only if a certain threshold level has been attained; until then, the effect is insignificant.
