Abstract:: Individual Transferable Quota (ITQ) systems have been used to control harvests and increase fisheries’ economic efficiency; however, they do not eliminate competitive fishing which can result in stock and congestion externalities that are especially apparent when resources are spatially heterogeneous within the controlled region of the ITQ system. These externalities...
