What is needed is not ever more refined analysis of a faulty vision, but a new vision. This does not mean that everything built on the old vision will necessarily have to be scrapped, but fundamental changes are likely when the preanalytic vision is altered. The necessary change in vision is to picture the macroeconomy as an open subsystem of the finite natural ecosystem (environment), and not as an isolated circular flow of abstract exchange value, unconstrained by mass balance, entropy and finitude. . . . .
The major task of environmental macroeconomics is to design an economic institution analogous to the Plimsoll mark–to keep the weight, the absolute scale, of the economy from sinking our biospheric ark.
The market, of course, functions only within the economic subsystem, where it does only one thing: it solves the allocation problem by providing the necessary information and incentive. It does that one thing very well. What it does not do is solve the problems of optimal scale and of optimal distribution. The market’s inability to solve the problem of just distribution is widely recognized, but its similar inability to solve the problem of optimal or even sustainable scale is not as widely appreciated. . . .
Economists have recognized the independence of the goals of efficient allocation and just distribution and are in general agreement that it is better to let prices serve efficiency, and to serve equity with income redistribution policies. Proper scale is a third, independent policy goal and requires a third policy instrument. . . . . The point is that the market’s criterion for distribution income is to provide an incentive for efficient allocation, not to attain justice. These two values can conflict, and the market does not automatically resolve this conflict. The point to be added is that there are not just two, but three, values in conflict: allocation (efficiency), distribution (justice), and scale (sustainability).
