A COMPARISON OF THE UTILIZATION OF STOCKS WITH PATCHY DISTRIBUTION AND MIGRATION UNDER OPEN ACCESS AND MARINE RESERVES: AN EXTENDED ANALYSIS - Anderson, Lee G.
This paper compares the utilization of fisheries that reside is spatially differentiated patches that are interrelated by migration under open access and marine reserves. The purpose is to provide a better understanding of fisheries operation in patches and to study the effects of marine reserves on aggregate stock size, harvest, and fleet size. It is an extension of a model developed by Sanchirico and Wilen (2001), SW. One extension is a detailed analysis of vessel behavior taking into account the distance from port. Another is the introduction of isogrowth curves and bioeconomic equilibrium stock (BES) curves that are used with...

APPLICATIONS OF DUAL THEORY IN FISHERIES: A SURVEY - Jensen, Carsten Lynge
This paper surveys empirical studies that utilize the theory of the firm and dual theory to reveal economic and technological conditions of fish harvesting firms. The dual approach is highly suitable for revealing disaggregated structures in fishing processes that consist of several inputs and outputs. Building on the functional forms of cost, profit, or revenue functions, the dual approach has improved our understanding of technological production conditions based on data at firm level. This is done by addressing a variety of different technological issues for multispecies harvesting firms, such as transformation between species, substitution between fishing inputs, economies of scope...

BANKRUPTCY OF FISHING RESOURCES: THE NORTHERN EUROPEAN ANGLERFISH FISHERY - Gallastegui, M. Garmen; Inarra, Elena; Prellezo, Raul
Since 1983 the Northern European anglerfish fishery, exploited by fleets of seven countries, has been regulated using a policy of Total Allowable Catch (TAC). In this paper, the strategy followed by the European Union (EU) in distributing the established TAC among the seven countries is explored. It is inferred that the EU has utilized a weighted proportional rule, taking the average catches for the period l97378 as the reference point. On the other hand, given that the fishery situation for the years 1993, 1994, and 1995 can be characterized as a bankruptcy problem, this paper also explores, as possible means...

DISTANCE VS. RAY FUNCTIONS: AN APPLICATION TO THE INSHORE FISHERY OF GREECE - Fousekis, Panos
The objective of this paper is to compare the empirical results from two alternative representations of a stochastic multi-output technology using trip-level data of the inshore fleet in Greece. The comparisons involve technical efficiency scores, structure of the underlying technology, and technical efficiency determinants. The stochastic multi-output distance function and the stochastic ray production function indicate the same technology structure, which is non-separable in inputs and outputs, non-homothetic in inputs, and exhibits increasing returns to scale. The relative rankings of efficiency scores are very similar. The distributions of efficiency scores, however, are different, and the ray production frontier yields systematically...
