During the past decade theoretical and empirical advances in neoclassical economics have resulted in the virtual rejection of the two pillars of traditional welfare economics-- rational economic man and perfect competition. Surprisingly, many ecological economists are moving closer to the discredited neo-Walrasian welfare model just at the time it is being replaced within the mainstream. We call for a return to the roots of ecological economics and an engagement with current developments in mainstream theory. (This abstract was borrowed from another version of this item.)
