Time series analysis of the nexus among corruption,political instability and judicial inefficiency in Pakistan

The purpose of this study is two folds: firstly, to analyze the direction of causality between corruption and political instability directly and secondly, to determine the causality between corruption and political instability indirectly through judicial inefficiency in Pakistan. The causality between corruption, political instability and judicial inefficiency is tested by applying Toda–Yamamoto Granger causality test. The results show that there is a lack of direct causal relationship between corruption and political instability. However, political instability and corruption cause each other indirectly through judicial inefficiency. The study highlights the critical role of judicial inefficiency leading to an important policy implication.
