Current methods for assessing capacity and its utilisation in fisheries operate at the firm-level, but neglect industry capacity. Here, we introduce the Johansen-Färe measure of plant capacity of the firm into a multi-output, frontier-based version of the short-run Johansen industry model. The model determines firm capacity utilisation such that current industry outputs are maintained, while minimising the use of fixed inputs at industry level and assuming abundant variable inputs. Policy extensions relevant to combating overfishing include tightening quotas, seasonal closures, linking economic and plant capacity, decommissioning schemes and area closures, implementation issues and equity considerations. The application to the Danish …

To solve the problem of illegal landings this article proposes a new tax mechanism based on the regulator's own aggregate catch estimates and ex ante self-reports of planned catch by fishermen. We show that the mechanism avoids illegal landings while ensuring (nearly) optimal exploitation and generating (nearly) correct entry and exit incentives. Finally we simulate the mechanism for the Danish cod fishery in Kattegat to obtain a rough indicator of the size of the tax. It turns out that the average tax payment as a percentage of profit is surprisingly low.
