RT Journal Article SR Electronic T1 The Revolution in Welfare Economics and Its Implications for Environmental Valuation and Policy JF Land Economics JO Land Econ FD University of Wisconsin Press SP 239 OP 257 DO 10.2307/3654741 VO 80 IS 2 A1 Gowdy, John M. YR 2004 UL http://le.uwpress.org/content/80/2/239.abstract AB Two research programs are brought together to contribute to the growing body of work on alternatives to standard welfare-based approaches to environmental valuation and policy. The first is the theoretical literature undermining the “new welfare economics.” The second is the growing body of work on endogenous preferences. Both these research programs point to the necessity of interpersonal comparisons in welfare economics. This paper focuses on (1) the theoretical flaws in the use of Potential Pareto Improvements as a policy guide, (2) the “filtering” of expressed preferences through the axioms of consumer choice, and (3) the role of endogenous preferences in a reformulation of environmental valuation and policy.
