A test for pluralism: Coherence, realism and relevance, and systems thinking in ecological economics.

摘要

This study intervenes into the debate regarding the definition of pluralism in ecological economics and how that definition affects various characterizations of ecological economics. The methodological pluralist camp argue for the inclusion of neoclassical economics into the ecological economics fold, while the critical pluralist camp argue against the inclusion of neoclassical economics. This study provides a critical exposition of the preanalytical visions of neoclassical and ecological economics that includes their respective ontological and epistemological foundations. Those foundations are critically scrutinized for coherence, realism and relevance, and their respective ability to analyze complex systems. It is argued that combining neoclassical and ecological economics renders ecological economics incoherent, and that neoclassical economics fails the test of realism, and its conceptual apparatus is only capable of analyzing simple systems. It is also argued that ecological economics is coherent, passes the test of realism because it is ontologically, socio-historically, and descriptively realistic, and the conceptual apparatus of institutionalist ecological economics incorporates complex systems. It is concluded that practitioners of ecological economics ought to reject and jettison neoclassical economics from their fold and to develop closer connections to and alliances with practitioners of heterodox economics. Keywords: Ecological Economics, Ontology, Coherence, Realism, Systems Thinking.
