John Hartwick celebrated fifty years in the Economics Department of Queen’s University, Kingston, Ontario in May 2019. He has published two textbooks and three monographs and many refereed articles in economics journals. In his best known article (American Economic Review, December 1977) he drew attention to the attractive implications of a society accumulating produced capital to compensate for currently using up a depleting natural resource such as oil. This idea has become central to the economics of sustainability.
