Overall, Earth Economics is an excellent source as an alternative introduction to macroeconomics. It can also assist scholars who want to study the subject from a more diverse and less mainstream angle. The book does great work in interlacing economic models, real world data and policy discussions, into a comprehensive, if unconventional, macroeconomics book.

Earth economics studies the economy of our planet from the perspective of an autarkic system (a “closed economy”). It ignores the constituent national and regional parts of the planet economy and focuses on the whole. The book respects the heritages of IS/LM (Keynes) and neoclassical growth (Solow) not out of economic respect but because these tools are very useful in understanding the crisis and the policy response to that crisis.
