Economists, who adopt the principle of consumer sovereignty, treat preferences as unquestioned for the purposes of their analysis. They also represent preferences for future outcomes as having value in the present. It is shown that these two characteristics of neoclassical modelling rest on similar reasoning and are essential to achieve high aggregatability of preferences and values. But the meaning and broader implications of these characteristics vary according to the arguments given to support these methodological choices. The resulting ambiguities raise questions (...) regarding economists' attitudes towards the study (by other disciplines) of preference formation and reformation. Under a strong, positivist interpretation (which is philosophically problematic), consumer sovereignty represents a rejection of any meaningful study of these subjects; under a weaker, methodological understanding, consumer sovereignty merely draws a boundary between economics and other disciplines. The weaker version is argued to be more defensible, and economists are urged to engage in interdisciplinary work that will clarify how preferences are formed, criticised and reformed. (shrink)

This paper presents a critical evaluation of Mark Sagoff's critique of economistic approaches to environmental decision-making in The Economy of the Earth. Whilst endorsing many of Sagoff's specific arguments against the use of extended versions of cost-benefit analysis in making such decisions, it criticises the conceptual framework within which these arguments are developed. In particular, it suggests that what Sagoff represents as a tension between consumers and their public roles as citizens is better understood as one between culturally shared values (...) concerning both the protection of nature and the pursuit of consumption; and that this conflict has itself to be resolved by them as citizens.

Four dogmas have shaped modern neoclassical economics. The first proposes that markets may fail to allocate resources efficiently, that is, to those willing to pay the most for them. The second asserts that choices, particularly within markets, reveal preferences. The third is the assumption that people always make the choices they expect will benefit them or enhance their welfare. The fourth dogma holds that perfectly competitive markets will allocate resources to their most beneficial uses. This is the doctrine of the (...) invisible hand. I argue that these dogmas of applied welfare economics should be abandoned. One consequence of doing so will be an increased interest in the institutional context of production. A second will be a turn toward empiricism. (shrink)

Deep ecological appeals for wilderness preservation commonly conjoin arguments for participatory land use decision-making with their central championing of natural areas protection. As an articulation of the normative meaning of participatory democracy, the discourse ethics advanced by Jürgen Habermas is employed to highlight the consistency and justifiability of this dual claim. I argue that Habermasian moral theory reveals a key tension between, on the one hand, an ethical commitment to wilderness preservation informed by deep ecological and bioregional principles that is (...) oriented to a naturalistic value order and, on the other, the procedural norms of democratic participation. It is claimed that discourse ethics thereby raises critical philosophical and practical questions concerning the political legitimacy of deep ecology. In examining the progressive claims of environmental philosophers and wilderness activists embracing this perspective, I draw empirically upon Canadian arguments for natural areas protection and associated radical prescriptions for a democratisation of land use decision-making.
