Technical efficiency in the Danish trawl fishery in the North Sea is estimated for 1997 and 1998 by a stochastic production frontier model. This model allows noise when the frontier and the technical efficiency is found, which for fisheries is a reasonable assumption. The results show that the...

Ecosystem externalities arise when one use of an ecosystem affects its other uses through the production functions of the ecosystem.We use simulations from a size-spectrum ecosystem model to investigate the ecosystem externality created by fishing of multiple species. The model is based upon...

This supporting material for An Indicator for Ecosystem Externalities in Fishing provides the estimations of the cost model parameters, establishes a price model, performs sensitivity analyses of the cost model parameters and analyzes sensitivity with respect to the control variable.
