Preface

These are my lecture notes for a course called Introduction to Macroeconomics that I have taught for over three decades.

The required textbook for my course is Brief Principles of Macroeconomics by N. Gregory Mankiw. Although Mankiw’s book is excellent, in my teaching I have constantly felt the need to make small adjustments. Until recently, I had been making these adjustments in the PowerPoint slides I use in the classroom. But the availability of new technology – especially R, R Studio, the bookdown package in R, and Github – has made it easy for me to gather my slides and turn them into a free online form that actually resembles a textbook.

I would be happy to get feedback.
