Creator:: Duy, Nguyen Ngoc and Flaaten, Ola
Abstract:: This study proposes three methods for technical efficiency (TE) estimation using three different fish stock proxy measures while applying the stochastic production frontier (SPF) approach. We apply these methods to two Vietnamese offshore fisheries, gillnet and hand-line, for which measures of stock abundance are unavailable. Based on the assumption of...

Creator:: Reithe, Siv, Armstong, Claire, and Flaaten, Ola
Abstract:: Assuming a broad set of management goals, we analyze the implementation of a marine protected area (MPA) together with open access by applying a bioeconomic model that ensures unchanged growth post-MPA. Taking into account that conservation and restoration, food security, employment and social surplus are amongst the objectives that many...
