One of the key questions confronting scholars of global governance concerns the role that international institutions play in world politics. International Relations (IR)theory has developed a number of distinct theoretical approaches to explain the power of international institutions and the factors that shape their creation. Each of these approaches differs in its basic assumptions about world politics, the actors it views as most consequential for global governance, and the role that institutions play in governing the world. Discuss how the three theoretical approaches of realism, liberalism, and constructivism differ in their approach to explaining global governance. Your answer should consist of three parts. In part one (1), for each of the three theories listed above identify the three assumptions underlying each approach and discuss how each approach explains the role that international institutions play in shaping global governance. In part two (2), discuss what these different perspectives suggest about the future trajectory of global governance and the durability of the current international order. What are the major challenges to world order envisioned by each of these three theories, and how would each theory suggest that they be managed? In the third (3) and final section, discuss which of these three perspectives you find most convincing as a theory of global governance and why.
