  • Rents and Rents Drain in the Icelandic Cod Fishery

    Creator:
    Arnason, Ragnar
    Abstract:
    This paper estimates current resource rents being generated in the Icelandic cod fishery and compares them to the maximum sustainable attainable ones. For this purpose a simple aggregative model of the cod fishery is specified and empirically estimated. It is found that in spite of the cod stock being in...

  • Triple Win for Trade in Renewable Resource Goods by Use of Export Taxes

    Creator:
    Flaaten, Ola and Schulz, Carl Erik
    Abstract:
    The majority of monitored fish stocks globally is fully or over exploited, that is, at or below their maximum sustainable yield stock levels. Despite this resource situation international trade in fish products have been increasing for a long time. An export tax on fish and fish products, as an alternative...

  • Trade, Resources and Subsistence

    Creator:
    Emami, Ali
    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.

  • Voluntary Approaches to Transitioning from Competive Fisheries to Rights- Based Management

    Creator:
    Knapp, Gunnar and Murphy, James J.
    Abstract:
    Despite potential advantages of rights-based management over competitive fisheries, there has been significant political resistance to rights-based management from many fishermen, which has slowed the adoption of rights-based management. This paper explores the concept of voluntary transitions to rights-based management, under which fishermen may choose between an allocated fishery (with...

  • Welfare Effects of Fisheries Boom in Lake Victoria

    Creator:
    Eggert, Håkan, Greaker, Mads, and Kidane, Asmerom
    Abstract:
    In this paper we try to assess the welfare implications of the Tanzanian fisheries boom following from the increase in quantities and prices of the Lake Victoria Nile perch export primarily to Europe over the last twenty years. We have a micro level perspective using data from a 1993 World...

  • Can Government Financial Transfers Ever Lead to Responsible Fishing? A (New) Trade Theory Parable

    Creator:
    Wilson, James R.
    Abstract:
    Recent literature on trade in fisheries products and in factors of production for fishing can be used to ask when it might be welfare increasing to encourage government financial transfers (GFTs) in the fisheries. Using numerical techniques and assuming a small open one factor 2 good economy with production inefficiencies...

  • Tev (total Economic Value) Analysis of A Marine Environment in Norway

    Creator:
    Aanesen, Margrethe, Armstrong, Claire, and Kahui, Viktoria
    Abstract:
    The push for ecosystem based management has opened up not only for including more of the natural systems when managing fish resources, but also a broader perspective on the human systems, and the diverse activities in the sea. This is reflected for instance in the EU Maritime Policy where fisheries...

  • The economics of size selective harvesting - the case of Barents Sea cod fisheries

    Creator:
    Andreasson, Stefan and Flaaten, Ola
    Abstract:
    Gear technologists have, in recent years, developed rigid sorting grids, Sort-X, in bottom trawls, to improve the size selectivity of this type of gear. Experiments with the Sort-X system in the aft sections of trawls were carried out aboard Norwegian and Russian trawlers along the coast of Northern Norway and...

  • Individual Discount Rate and Regulatory Compliance in a Developing Country Fishery

    Creator:
    Akpalu, Wisdom
    Abstract:
    Studies on compliance with fishing regulations have looked at fishery crimes for which the offender faces a one-period decision problem of maximizing an expected utility. Moreover, the returns to the crimes are uncertain because the offender may lose them if caught. This paper extends these models by considering a fishery...
