With the increasing internationalisation of conflict, crime, and violence, domestic political stability and law enforcement capability have now become regional and global public goods.

This report documents how permeable country borders have become in many different domains, and the troubling human and economic costs. The geographical spillovers of conflict and crime and political instability have intensified.

The report finds that the impact of foreign interventions (whether military interventions or development assistance) on violence is ambiguous and context-specific. Military interventions might increase the state’s ability to control crime and insurgency but might also worsen citizens’ attitudes toward the government.

Global institutions have a role to play in the provision of security. The report identifies areas of relevance for multilateral institutions:

• Generating data and knowledge for better policies
• Delivering financial aid and technical expertise
• Providing a forum for policy coordination
