ECONOMICOLOGY II, a sequel non-fiction book by Peter M. Wege published in 2010, defines the author's environmental philosophy that mankind must balance the needs of the economy with those of the ecology. Wege summarizes the writings of several leading environmental thinkers to support his thesis of economicology as the best way to achieve sustainability.

In this book, sociologists, philosophers, and economists investigate the conceptual issues around the performativity of economics over a variety of disciplinary contexts and provide new case studies illuminating this phenomenon. In featuring the latest contributions to the performativity debate the book revives discussion of the fundamental questions: What precise meaning can we attribute to the notion of performativity? What empirical evidence can help us recognize economics as performative? And what consequences does performativity have for contemporary societies? The contributions demonstrate how performativity can serve as a powerful conceptual resource in dealing with economic knowledge, as an inspiring framework for investigating performative practices, and as an engine of discovery for thinking of the economic proper.
