Teaching Style

Professor Sunstein is an extraordinarily prolific and accessible teacher who blends behavioral economics with legal analysis. He uses a conversational Socratic style, cold-calling students but maintaining an approachable tone that encourages open dialogue. His classes are fast-moving and idea-rich, often introducing novel frameworks for thinking about regulation, rights, and decision-making. Expect to engage with interdisciplinary insights from psychology and economics.
