Neoliberalism in international relations emphasizes the role of institutions in facilitating cooperation among states, suggesting that cooperation can be achieved even in anarchic conditions through effective institutional design. It draws on rationality and utility-maximization, asserting that collective benefits can be realized through increased interaction and information exchange among self-interested actors. The emergence of neoliberalism is linked to historical developments and critiques of realism, positing that modern interdependence and institutional frameworks can successfully mitigate the challenges of an anarchic international environment.
