Political and bureaucratic corruption is a societal threat in every country. It allows organised crime to flourish, slows economic growth, increases income inequality, reduces government effectiveness, and threatens citizens’ confidence in the rule of law. This study uses a “System Dynamics model” from a framework based on econometric analysis wherein the causal relationships between the economic and governance institutions were established. The calibrated model uses the data on institutional quality from 1996 to 2020 from “the World Bank and the World Economic Forum” to project institutional quality and control corruption in the future. The control of corruption was trending downward in the nations studied. The model shows that improving institutional quality can reverse this downward trend. However, improving institutional quality and controlling corruption requires a country-specific approach. This model suggests the most efficient ways that national leaders and policymakers can improve institutional quality and thereby control corruption in their country.
