=== Guns and butter curve ===

According to Investopedia: "The guns-and-[[butter]] curve is the classic economic example of the production possibility curve, which demonstrates the idea of [[opportunity cost]].

As an economy produces more guns (military spending) it must reduce its production of butter (food), and vice versa."<ref>[https://www.investopedia.com/terms/g/gunsandbutter.asp Guns-and-Butter Curve: Definition and How It Works], Investopedia</ref>
