Let me put the positive up front. Professor Herman Daly and his colleagues in the school of ecological economics (SEE) have made important contributions to the study of sustainability and have increased awareness on the relations between economics and the environment. But there are serious problems with their approach that will hamper the future development of SEE. This is why I want to raise a couple of critical issues. What follows is a discussion on value theory that may sound old fashioned, but it needs to be brought out if we want to move ahead with a more meaningful discussion on economic forces and the environment.
According to Daly and colleagues, the fundamental problem with mainstream economic theory is its inability to analyze physical flows in economic systems. The story line is that conventional economic theory relies on the fallacy of a circular flow of commodities in a system in which natural resources are not finite. The flows are expressed in abstract or monetary units and can therefore be expanded indefinitely. According to Daly, from this flawed beginning of “money fetishism” economics erroneously concludes that physical quantities are also amenable to infinite growth.
