The internal structure of effort in Greek fisheries: an empirical analysis

The objective of this paper is to investigate the internal structure of eff ort in the Greek open-sea fishery. For this purpose, a translog effort prod uction function is applied to survey data collected in 1996. The empirical results indicate that ample substitution possibilities exist between labour and capital and labour and energy. In contrast, the substitution possibili ties between capital and energy are limited. The compensated own-price dema nd elasticities are lower than one. To further access the internal structur e of effort, the estimated model has been subject to a barrage of separabil ity tests (global, linear and nonlinear). In all cases, the assumption of i nput separability has been decisively rejected. (C) 1999 Elsevier Science B .V. All rights reserved.
