This paper provides the first ex post estimates of the effects of input controls on technical efficiency in a fishery. Using individual vessel data from the northern prawn fishery of Australia for the years 1990-1996 and 1994-2000, stochastic production frontiers are estimated to analyse the...

The paper develops a benchmarking framework to improve fisheries governance and promote resilient ecosystems and profitable fisheries. The benchmarking includes five key components: accountability; transparency; incentives; risk assessment and management; and adaptability. Collectively, these...

This paper uses data from an actual fishery to construct a tractable and dynamic model to compare expected profit and its variance, optimal stock size, optimal harvest rate and optimal fishing effort under different management regimes under uncertainty. The results provide a comparison of...

The paper explains the large differences in cross-country productivity performance by modeling and testing the effects of social barriers to communication on productivity and capital accumulation. In an optimal growth model, social barriers to communication that impede the formation of knowledge...

The paper analyses the economic payoffs from marine reserves using a stochastic optimal control model. The results show that even if the reserve and harvested populations face the same negative shocks, harvesting is optimal, the population is persistent and with no uncertainty over current stock...

Using data from what was once one of the world’s largest capture fisheries the economic value of a marine reserve is calculated using a stochastic optimal control model with a jump diffusion process. The results show that with a stochastic environment an optimal-sized marine reserve can...

The paper presents the first ex-post analysis of profit and productivity of individual vessels following a vessel or licence buyback in a fishery. Using individual firm-level data for the period 1997-2000, the paper analyzes a “natural experiment" of the effects of a 1997 scheme to reduce...

Unpredictable environmental fluctuations are a major problem in fisheries. To mitigate these uncertainties, reserves are advocated to help ensure population persistence, reduce population and harvest variance and to provide a ‘hedge’ against management failures. Using recent insights from...
