Welcome to the world of economics! This course is an entry level course in the field of economics. The main purpose of this course is to help you understand economists’ way of thinking --- almost everything can be put into the framework of demand and supply, and the market will clear at the equilibrium price. As you may know, economics can provide a very unique angle to explore many fundamental and important questions in social science. You will have a better understanding of how the society & economy works after taking this course. You can also build your own critical thinking about many policies which can be seen in our daily life. You will also have opportunities to improve your communication skills (eg. oral presentation and academic writing) throughout this course.
