The BA program in Philosophy, Politics and Economics (PPE) provides students with a set of interdisciplinary tools to think rigorously about complex social problems. Students learn about the relationship between markets and morality, the role institutions play in shaping our politics and economics, and how social norms can shape our behavior. Societies are rife with deep disagreements about what constitutes justice. Students who study PPE will gain a deeper understanding of the complexities of our political life, and tools for promoting positive social change. After receiving training in the core methods of PPE, students choose to focus on one of three thematic domains, each relating to a particular level of governance: Local, National and Global. This allows students to gain a detailed understanding of the challenges unique to their chosen level. Students will complete their degree with practical tools to solve important problems.
