Corruption is destructive, costly and epidemic to neighboring countries as it is compounded by transnational elements. To the extent that transnational bribery undermines fair competition both at home and abroad, it has the effect of increasing the cost of cross-border transactions. In a recent study, the Korea Institute for International Economic Policy (KIEP) attempted to measure the impact of corruption control on trade and welfare using the aforementioned corruption perception index of the TI. According to the results of this estimation, trade costs decreased roughly by 0.4% when the corruption perception index increased by 1%. There is no denying that individual economies should address corruption issues in their national agenda as top priority, then design and enforce tailored anti-corruption measures However, no single country can resolve this intriguing and burdensome mission alone. Only co-operation leads to co-prosperity.
