Uma genealogia dos enfoques positivos e contribui es normativas no debate econ mico sobre meio ambiente

Since the revival of environmentalism in the 60′s, research programs in Economics tend intensely to integrate environmental issues. Throughout the subsequent decades, the path of economic ideas about the theme has not been restricted to mainstream contributions, but has also reached a great deal of the profusion of approaches that coexist and are in conflict in the academic arena as well as in the information and implementation of public policies. The purpose of this paper is twofold. Firstly, it focuses on the identification of important theoretical approaches that have influenced the economic explanation of environmental problems and the building of instruments for policy design and implementation. Secondly, it presents an exercise to elaborate a genealogy of approaches and contributions that aims to sketch the origin or theoretical affiliation of positive and normative treatments that are found currently in the economic literature focused on environmental matters.
