Syllabus and Books
The syllabus for your course can be found on your CSUN Canvas account. You do not need to buy any books for my Econ 409. For Econ 310, I use Browning and Zupan's "Microeconomics: Theory and Applications." You do not need the newest edition.
Resources for Economists
This excellent resource is maintained by the American Economics Association. It provides links to economic data, blogs, information about the profession, etc.
