Isolated actions are impossible. A policy which is not carefully enough thought will carry along various perverse and adverse effects for the ecology as much as for theeconomy. Many suggestions to save our environment and to promote a model of 'sustainable development' risk indeed leading to reverse effects. Moreover, he evokes the bounds of public action which areunderlined by the public choice theory: the quest by politicians of their own interests, lobby pressure, partial disclosure etc. He develops his critique by noting the vagueness of the expression, which...
