Measuring efficiency in demersal trawlers using a frontier production function approach
نویسندگان
چکیده
A main feature of European fisheries management is a programme to reduce the level of capacity in EU fisheries. A criticism of such programmes is that the remaining fleet can increase their level of fishing effort thereby reducing the benefits from the programme. The extent to which the remaining fleet is capable of increasing effort is partly dependent upon the current level of efficiency of the fleet. If the current fleet is largely operating on an inefficient basis, then effort can increase through reducing the inefficiencies. In this study, the level of efficiency of individual demersal trawlers operating in the English Channel is estimated using a stochastic frontier production function. The causes of any inefficiencies are explained based on the characteristics of the boats making up the fleet. Measures are undertaken to distinguish under-utilisation of capacity from technical inefficiency. This study is part of the EU funded project 'Bio-economic modelling of the fisheries of the English Channel' (CT-96-1993).

Reducing fleet capacity in European fisheries is an important objective of the European Union’s Common Fisheries Policy. The success of such programmes depends both on the variation and the level of efficiency within the fishing fleets. If vessels with significantly lower than average efficiency levels are decommissioned, the actual reduction in fishing capacity will be less than expected. Furt...

Measuring the efficiency of a three-stage network using data envelopment analysis approach considering dual boundary
This paper presents a method for performance evaluation, ranking and clustering based on the double-frontier view to analyze the complex networks. The model allows us to open the structure of the “black box” and can help to obtain important information about efficient and inefficient points of the system. In this paper, we consider a three-stage network, in respect to the additional desirable a...
