Course Description: Economists study human behavior using a combination of models and data. Ec 10a introduces students to economic models by using intuitive discussions, graphical analysis and, in some cases, a bit of algebra. The models study individual decision-making and markets, and range from classical approaches like supply and demand to more recent approaches that consider informational limitations and behavioral mistakes. We will also use data to understand the strengths and weaknesses of these models. The course discusses the role that ethics and values play in people’s choices and in policy discussions. The ultimate goal of the course is to provide students with a set of tools that will help them develop answers for themselves on how to make better choices and participate in debates on major public policy issues in a wide range of domains such as taxation, inequality, discrimination and the environment.
