In this lecture, we continue to discuss the economics of fisheries -- private and open-access. The lecture reminds us of the logistic growth characteristics of fish populations and then presents a bio-economic model relating effort to harvest yield assuming that a fishery has reached steady-state. This bioeconomic fishery model allows us to predict that, for a private fishery, the fishery will never be biologically overfished. However, an open-access fishery may be both economically and biologically overfished. We then discuss how a common property fishery might be economically overfished but will at least be sustainable (i.e., not biologically overfished) in many cases. We end the lecture with a preview of the last lecture of new content for the semester -- a comment on the Pigouvian and Coasean approaches for thinking about environmental economics (and internalizing negative externalities due to environmental damages from production).
