This course is an introduction to how economists, in particular macroeconomists, think about the world. It is required for students that will major in economics and recommended along with ECO110 to those who want an overview of economics. Any other course you take in economics will build in part upon the knowledge and skills you develop in ECO111, along with ECO110. Hence, some fundamental concepts will be covered with some degree of complexity, even though this is an introductory course.
