This course is open to anyone, without a background in Economics, who is curious about Economics and why it has such a big impact on our lives. Economic theory is the social science of choices, whether that choice is made by an individual, a firm, a government or a planet. It is a science in that economists try to explain and rationalize behavior through models and hypothesis testing. It is social because, at the end of the day, interaction between economic agents is what drives the most interesting and engaging questions. This course will introduce to you what it means to “think like an economist.” We begin with the foundations that underlie all of economics. We then divide and explore the two broad divisions within economics: microeconomics, which looks at individual agents’ behaviors and their interactions in markets, and macroeconomics, which deals with broad trends of the economy. We will tie theoretical concepts with practical economic issues of our concrete world.
