The economics literature on fisheries has focused primarily on stock externalities and, to a lesser degree, on crowding externalities. Yet for many fisheries, harvesting activities may affect the underlying biological productivity of the fish stock by impacting the forage or habitat quantity or...

Failure to manage the harvest of a metapopulation at its underlying ecological scale can lead to extirpation of discrete subpopulations and reduce productivity. However, it may be difficult and costly to assess and manage stocks at a finer spatial scale, and there is generally greater...

In his seminal work on common property resources, H. Scott Gordon proposed that in a fishery with multiple grounds, effort would be distributed such that profit rates would be equal among them. Gordon's model relies on implicit assumptions that are inaccurate and lead to false conclusions in...
