Technical efficiency determinants for fisheries: a study of trammel netters in Greece

摘要

This paper provides an assessment of technical efficiency (TE) and its interactions with vessel- and skipper-characteristics for the fleet of trammel netters in Greece. This is achieved using trip data from a sample of vessels and a theoretically consistent approach which involves the simultaneous estimation of the stochastic frontier model and the inefficiency model by ML methods. The empirical results suggest that there is potential for short-run output increases without additional fishing effort. They also suggest that vessel- and (to a lesser extent) skipper-specific characteristics do influence TE levels.
