This paper discusses the dimension problem in economic aggregation, as it relates to ecological and biophysical economics. The dimension problem consists of a simple dilemma: when we aggregate, the observer must choose the dimension of analysis. The dilemma is that this choice affects the resulting measurement. This means that aggregate measurements are dependent on one’s goals, and on underlying theory. I explore the consequences of this predicament for ecological and biophysical economics. I discuss the many problems of using ‘real’ monetary value as the dimension of analysis. And I highlight how the dimension problem undermines the practice of seeking ‘optimal’ policy. Although there are no solutions, I discuss ways that ecological and biophysical economists can deal with the dimension problem.
