Course Outline and Method

In this introductory course we will study the causes and consequences of human decision making, market behavior and implementations of public policies. Microeconomics explores how consumers and firms behave, markets function, and government policies can shape economic results. Using basic microeconomic models, students will learn to evaluate microeconomic issues, including current events. This course aims to develop students' ability to understand how markets work as well as their everyday decision making.
