Technical Note on the Keynesian Model

In class, I focus on explaining the Keynesian model in words and with diagrams. I don’t walk through the underlying math, mainly because most students find diagrams easier to follow. However, going through the math at least once – at your own pace – will help you better understand the diagrams and how to use them correctly; and some students may find the math easier than the diagrams, or useful to double-check answers from graphs.
