A note on Heterodox Macroeconomics by Blecker and Setterfield

Blecker and Setterfield's new textbook from 2019 presents an updated discussion of heterodox models of growth and distribution. This note clarifies and elaborates on three important issues discussed in the book. First, the text presents mainly one-sectoral and one-technique models, which is a reasonable set-up to keep things simple but not always enough to discuss some controversial issues. Second, continuous substitution is important but not essential for neoclassical growth theory. Third, the popular Goodwin model presented in the text does not produce 'limit cycles.'
