According to liberal international relations theory, absolute gain is what international actors look at in determining their interests, weighing out the total effects of a decision on the state or organization and acting accordingly. The international actor's interests not only include power but also encompass the economic and cultural effects of an action as well. The theory is also interrelated with a non-zero-sum game which proposes that through use of comparative advantage, all states who engage in peaceful relations and trade can expand wealth.
