The required textbook for this course is Essentials of Economics (9th edition) by Sloman, J. and Garratt, D. This textbook is crucial for you to use together with the supplementary video lectures. If you are unable to purchase the hard copy, here is the e-book version free for you to download and use. 

Note: 

My lecture slides are mainly based on this textbook. Please refer to it for further reading and understanding of the concepts learned in class as lecture slides can be quite brief.
