This chapter discusses the impact of particular policies at the global level. It turns out that coordination and common standards can make a big difference. First, it is shown that the global traceability of minerals can cut rebel funding significantly. Next, the role of monitoring multinationals is highlighted. Notably, recent studies have pinpointed the importance of corporate social responsibility of mining firms, revealing that the best-run mineral extractors may have a beneficial impact on the local population, while poorly run firms yield disastrous outcomes. Further, given that wars tend to trigger a series of vicious cycles, there is a powerful case for facilitating refugee admission. It is discussed how a well-coordinated refugee policy can reduce violence perpetuation over future generations. Next, we investigate what role international trade can play for fostering peace and what harmful effects arms trade can entail. It is shown how arms-producing countries can – without bearing large economic costs – reduce the ability of bad regimes to attack their civilians. Finally, the importance of a rule-based international order and a well-managed green transition is highlighted.
