Virtual Population Units: A New Institutional Approach to Fisheries Management

This paper describes an alternative, rights-based approach to the economic problems of fisheries management and governance. The approach is based on the concept of a Virtual Population (VP), which provides an alternative way to define use rights in a fishery management system. Included is a comparison of harvest rates under the VP regime, “sole-owner,†and open-access regimes. In comparison, a VP solution is more efficient than open access and can approach that of a sole owner. More importantly, in our opinion, the approach contains a higher degree of local control over issues such as concentration of ownership and, unlike some community-based systems, provides an explicit, decentralized incentive for conservation. It also contains a built-in incentive mechanism for end-of-year conservation that is absent from individual transferable quotas (ITQs).Virtual populations, virtual population units, ITQs, marginal valuation, Resource /Energy Economics and Policy, Q220, Q590, C720, D830,

Economic Benefits of American Lobster Fishery Management Regulations

A simulation model is used to compare measures for future management identified in the American lobster fishery management plan; specifically, increases in the minimum legal size and a modest reduction in aggregate fishing mortality are evaluated. The analysis differs from previous work in that the distributional aspects of the alternative management regulations are quantified. The results indicate that (1) both an increased minimum size and a reduction in fishing mortality are economically justified in the sense that net benefits are positive; (2) increasing the minimum size without an adjunct regulation to prohibit entry will cause present fishermen to suffer an initial short-term reduction in revenues for which there will be no long-term gain; (3) because increased minimum size can be justified on the basis of consumer benefits alone, arguments favoring its increase to prevent recruitment failure are moot as far as a test of national economic efficiency is concerned; and (4) a program of effort reduction which reduces by 20% the fraction of available lobsters captured annually is projected to generate SI of producer benefits for every pound of lobster landed. Reducing the annual harvest fraction by 20% results in a level of fishery benefits greater than increasing the minimum size to 89 mm (3^-in.), and increases the coincidence of short-run costs and long-term benefits among those impacted by fishery management.Environmental Economics and Policy, Resource /Energy Economics and Policy,

Understanding Mammalian Genetic Systems: The Challenge of Phenotyping in the Mouse

Understanding mammalian genetic systems is predicated on the determination of the relationship between genetic variation and phenotype. Several international programmes are under way to deliver mutations in every gene in the mouse genome. The challenge for mouse geneticists is to develop approaches that will provide comprehensive phenotype datasets for these mouse mutant libraries. Several factors are critical to success in this endeavour. It will be important to catalogue assay and environment and where possible to adopt standardised procedures for phenotyping tests along with common environmental conditions to ensure comparable datasets of phenotypes. Moreover, the scale of the task underlines the need to invest in technological development improving both the speed and cost of phenotyping platforms. In addition, it will be necessary to develop new informatics standards that capture the phenotype assay as well as other factors, genetic and environmental, that impinge upon phenotype outcome

Indirect Benefits and Fisheries Management-A Case Study in the Mid Atlantic Region

Indirect benefits have a long history in the literature of benefit-cost (B-C) analysis. A commonmeasurement tool for indirect benefits is the Leontief or Input Output Model (I-O), and this paper discussesindirect benefits as if they are identical to I-O analysis. The B-C literature disparages I-O for assessing theeconomic efficiency of a project but does admit its possible usefulness in connection with distributionalconsiderations, including inter-jurisdictional cost sharing. To illustrate, the paper draws on recent researchon Mid-Atlantic recreational fisheries. The nature of fisheries is such that I-O is an especially ill-suited toolfor efficiency analyses. However, in a concluding section, reference is made to a way in which I-O could beuseful. It appears that this application may be better suited for the commercial fisheries than for recreationalfisheries.Keywords: Fisheries Economics, Fishery Management, Special Topics, Valuing Recreational Fisheries and Modelling Human Responses to Changes in their Management RegimesKeywords: Fisheries Economics, Fishery Management, Special Topics, Valuing Recreational Fisheries and Modelling Human Responses to Changes in their Management Regime
