Pomatto's section (second term) An introduction to economic methods, models, and institutions. The course focuses on a set of foundational questions: what prices represent, how they are determined, and how they function to allocate goods and resources. The class emphasizes abstract reasoning and formal arguments. Students seeking a wide-ranging introduction to economic institutions may prefer Professor Druckenmiller’s section. This version of the course is concentrated on a narrower set of topics.  Druckenmiller's section (third term): This course provides a rigorous introduction to microeconomic theory at a level comparable to an intermediate course, using calculus to analyze how individuals and firms make decisions and how these decisions shape markets. Students develop demand from consumer optimization and supply from firm cost minimization and profit maximization, then study competitive markets, general equilibrium, and welfare. The course emphasizes applying theory to real-world problems and policy questions, while also examining departures from perfect competition, including market power, uncertainty, incomplete property rights, and asymmetric information. Students seeking an introduction to economics based in first principles may prefer the section taught by Professor Pomatto.
