Microeconomics
MIT OpenCourseWare's Microeconomics covers how markets allocate scarce resources, profit maximizing behavior under different competitive structures, and how trade and technology change the choices people and firms face. The course applies these tools to real problems, including the housing bubble, unemployment among high school graduates, Google's revenue model, and rising healthcare costs. Materials include lecture notes, problem sets, and exams from MIT's course, giving a full semester's structure for self-study. No enrollment or certificate is offered, but all readings and assignments are posted for free use under MIT's open license. Suited to anyone wanting a rigorous grounding in supply and demand, market structure, and applied policy questions, taught at the level of an undergraduate economics course.
