The study of macroeconomics has traditionally involved little consideration of the environment. But today macroeconomic futures are increasingly bound up with environmental considerations, especially global climate change but also resource limitations and threats to other ecological life support systems. How can macroeconomic policy be reoriented to take environmental constraints into account? Should consumption and economic growth be limited? What is the outlook for technological change and employment? These questions are increasingly important both for theory and teaching. Jonathan Harris will discuss how GDAE researchers are addressing them in two forthcoming new text editions.
