Creator:: Armstrong, Claire W., Armstrong, Richard J., and Reithe, Siv
Abstract:: A bioeconomic model allowing different degrees of harvesting closures for two sub-stocks consisting of mature and immature fish is presented. Hence the model opens for partial closures of fisheries on both sub-stocks. Migration between the two sub-stocks is defined as recruitment of the young to the mature sub-stock, and egg...

Abstract:: Most trade literature is concerned with gains from free trade under the assumption that traded goods are produced under complete property rights. Seldom have researchers examined the consequences of free trade in the presence of incomplete property rights over renewable natural resources. In this paper, we explore these consequences. In...

Abstract:: It is well known that world production of shrimp, particularly farm-raised product, has increased significantly since the early-to-mid 1980's and that much of the product is directed to the U.S. market. Less well known is the fact that the product composition of the U.S. imported product (e.g., headless shell-on, peeled)...

Abstract:: In recent years, considerable attention has been given to the effects of removing trade restrictions on natural resource utilization and on poverty, especially in developing countries. Our paper adds to the growing body of conceptual work to show conditions under which a developing country that, in isolation, is unable to...

Creator:: Innes, James, Thebaud, Olivier, Norman, Ana, Little, Rich, and Kung, John
Abstract:: In multi-species fisheries managed under ITQs, the existence of joint production may lead to complex catch-quota balancing issues. Previous modelling and experimental research suggest that, in such fisheries, some fishers may benefit from the ability to trade packages of fishing quotas, rather than fulfill their quota needs by simultaneously bidding...

Abstract:: Multiobjective decision analysis (MDA) is a useful assessment method when fishery managers need a systematic investigation of the trade-offs involved in the selection of alternative policy options. An important class of techniques within MDA is vector optimization, consisting of mathematical programming models with vector valued objective functions. From the management...

Abstract:: Linear approximate almost ideal demand system was employed to estimate demand for Thai frozen shrimp in the United States of America, the main importing country for Thai frozen shrimp. Import demands for the same products from Bangladesh, China, Ecuador, India, Indonesia, Mexico, and Vietnam were simultaneously estimated to compare with...

Abstract:: Using a general equilibrium model that has a resource (fisheries) sector and that incorporates subsistence consumption into consumer preferences, we examine the costs and benefits of participating in international trade. In some cases income transfers may permit potential, but otherwise unachievable, gains from trade to occur.

Creator:: Guttormsen, Atle G.
Abstract:: In this paper an extended version of the well-known Faustmann model is developed for solving the rotation problem in fish farming. Two particularly important aspects of the problem are emphasized: namely first, the possibilities for cycles in relative price relationships and second, the problem with limitations in release time for...
