We give a broad review of a variety of econometric procedures to estimate technical efficiency and compare the results of several of them based on an application to the purse-seine fishery operating in the Gulf of Cádiz in 1998 and 1999. As these approaches provide different technical efficiency estimates, they might have different policy implications. Two conclusions are obtained: firstly, the higher the useful life of vessels is, the smaller the technical efficiency is; and secondly, the present total allowable catch regime based only on vessels larger than 12 m is unsuitable for this fishery.
