Please answer the question "Why Theory Matters in IPE?" You should focus on the epistemological question, but at the same time, it also deals with a brief description and critical assessment of some major theoretical perspectives: "liberal" (also related to "Keynesianism", "neoliberalism"), "nationalist and mercantilist", "Marxist" (also considering "world system" and critical theories) perspectives. 1. Discuss theory in general and its important functions in our thinking and analysis 2. Explain each theoretical perspective succinctly. 3. Reveal your position on how theories (a single one, a combination of some, or all necessary tools) work and discuss these questions critically: Why is this perspective the most convincing one for you?
