The book is a collection of essays in honor of the head of SCEPA’s climate project, New School Economist Willi Semmler. It covers Semmler's work on sustainable development, economic growth, technological change, climate change, commodity markets, long wave theory, nonlinear dynamic models, and boom-bust cycles. Semmler’s long-time co-authors, Lucas Bernard and Unujargal Nyambuu, edited the volume of essays by many of Semmler's former students and collaborators. Former New School Professor Ed Nell wrote the forward, and New School PhD Alex Gevorkyan contributed an introduction on Semmler’s impact on contemporary economics. Other contributors include Duncan Foley, Christian Proano, Daniel Samaan, Rajiv Sethi, among others.
