Erratum for “on the Sustainable Program in Solow’s Model”

In spite of the fact that the main claim of our paper (Withagen et al. [2003]) remains valid, its proof included incorrect components and needs amendment. In this note we briefly indicate the essence of the corrections needed. A new full version of the paper has appeared in Asheim [2007, Chapter 12] and it can be downloaded from http://folk.uio.no/gasheim/WAB-Nc03.pdf. An important step in the proof was, and still is, to characterize the solution to the minimum resource use problem. This is the problem of finding the program that minimizes total resource use needed to achieve the maximin consumption, given at the outset. In the original paper it was claimed that minimum resource use coincides with the resource stock initially available to the economy. Our proof borrowed an idea used by Cairns and Yang [2000] entailing that, since a uniform decrease of the consumption rate allows for a finite decrease of the resource
