A dual measure of capacity utilization is developed for multiproduct, revenue-maximizing firms. Under the assumption of revenue maximization, the sensitivity of CU to a change in an individual product price is shown to be directly related to the product-specific scale elasticity. The results are...

This paper provides a profit-maximizing model with vessel-level dolphin mortality limits for purse seiners harvesting tunas in the eastern tropical Pacific Ocean. The model analytically derives the shadow price (estimated economic value) for dolphin mortality, the fishing-fleet size, and the...

The analysis of technical efficiency in developing country agriculture is well established but has been overlooked for developing country commercial marine fisheries. Policies raising technical efficiency in agriculture are viewed as uniformly positive but are a mixed blessing in fisheries due...

Measures of multifactor productivity growth in natural resource industries are misleading without accounting for the effects on the environment. This paper introduces environmental effects into an output-oriented Malmquist index of multifactor productivity growth in order to evaluate growth in...

Artisanal fishing communities include some of the poorest fishers in Malaysia. The paper presents the first technical efficiency study, whichfinds that artisanal fishers are poor, but enjoy a higher level of technical efficiency than found in the other Malaysian gill net fisheries. It suggests...

The failures of traditional target-species management have led many to propose an ecosystem approach to fisheries to promote sustainability. The ecosystem approach is necessary, especially to account for fisheryï¾–ecosystem interactions, but by itself is not sufficient to address two...
