Ecological Benchmarking To Explore Alternative Fishing Schemes To Protect Endangered Species By Substitution : The Danish Demersal Fishery In The North Sea, Niels Vestergaard, Jens Kjærsgaard, Kristiaan Kerstens Dec 2008

Ecological Benchmarking To Explore Alternative Fishing Schemes To Protect Endangered Species By Substitution : The Danish Demersal Fishery In The North Sea, Niels Vestergaard, Jens Kjærsgaard, Kristiaan Kerstens

The cod stock in the North Sea is threatened by overexploitation. To recover this fishing stock, pressure needs to be reduced. This implies that catch compositions with small amounts of cod are preferred by public policy makers. The present analysis assesses the technological efficiency of fishing trips in terms of the substitution possibilities away from cod by considering landings of cod as an undesirable output. A conservative non-parametric frontier technology approach imposing minimal assumptions and based on directional distance functions is applied to explore alternative fishing activities for Danish gill netters operating in the North Sea with the goal of ...


Revenue-Based Capacity Utilisation Measures And Decomposition: The Case Of Danish North Sea Trawlers, Erik Lindebo, Ayoe Hoff, Niels Vestergaard Dec 2006

Revenue-Based Capacity Utilisation Measures And Decomposition: The Case Of Danish North Sea Trawlers, Erik Lindebo, Ayoe Hoff, Niels Vestergaard

Niels Vestergaard

In fisheries, capacity analysis has largely been limited to measuring physical capacity, defined as the maximum amount of output that can be produced per unit of time, given existing plant and equipment and unrestricted availability of variable inputs. An economic measure of capacity can be defined as the maximum revenue attainable for the given fixed inputs, using relevant outputs and output prices. This paper examines these two approaches to capacity by applying data envelopment analysis to physical and economic input/output data for Danish North Sea trawlers. The economic and physical measures are compared and contrasted using correlation analysis. An ...


Illegal Landings: An Aggregate Catch Self-Reporting Mechanism, Lars Gårn Hansen, Frank Jensen, Niels Vestergaard, Urs Steiner Brandt Dec 2005

Illegal Landings: An Aggregate Catch Self-Reporting Mechanism, Lars Gårn Hansen, Frank Jensen, Niels Vestergaard, Urs Steiner Brandt

Niels Vestergaard

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.
