Microeconomic Theory I

Graduate-level microeconomics that rebuilds the standard producer-consumer-equilibrium story from rigorous axiomatic foundations, then pushes into when markets deliver efficient outcomes and when they fail. You'll spend most of your time working through proof-heavy problem sets out of Mas-Colell, with five quizzes and two written exams testing whether you can actually derive results rather than just recite them. It's the spring core requirement that follows the fall micro sequence and underpins everything you'll do in field courses afterward, so treating it as a math course with economic interpretation tends to pay off more than treating it as economics with math.
