  • Regulations, Risk, and Rent Seeking Behaviour with application to fisheries

    Creator:
    Brandt, Urs and Bergfjord, Ole Jakob
    Abstract:
    This paper seeks to address how political risk influences behaviour, in particular rent seeking behaviour. Such risk is important in many industries, which posts challenges both for policy makers and economic agents. This paper studies how political uncertainty affects rent seeking, and what level of political uncertainty is optimal for...

  • International fish trade and fish product security in Viet Nam

    Creator:
    Hien, Thi Tran, Kim, Anh Nguyen Thi, and Petersen, Elizabeth
    Abstract:
    In 2006, Viet Nam’s fishery sector contributed about 6.1 percent to the GDP of the country and the value of aquatic products in export turnover was about US$ 3.3 billion. This accounted for 9-10 percent of the country’s total export value (MOFI/USDAFAS, 2007). Home consumption of fish has increased from...

  • The Economics of Overexploitation Revisited

    Creator:
    Grafton, R. Quentin, Kompas, Tom, and Hilborn, Ray
    Abstract:
    About 25% of the world's fisheries are depleted such that their current biomass is lower than the level that would maximize the sustained yield (MSY). Using methods not previously applied in the fisheries conservation context, we show in four disparate fisheries (including the long-lived and slow-growing orange roughy) that the...

  • Fish and Community in Flood-prone Areas of the Mekong River Delta, Vietnam

    Creator:
    Sinh, Le Xuan
    Abstract:
    The Mekong River Delta plays an essential role to Vietnam’s economy in terms of both rice and fish production. Annual flooding water and a rich level of aquatic resources strongly affect about 10 million local people, as well as extend beyond the boundaries of wetland itself. Flooding water and wild...

  • Non-convexity and the Sustainability of the Indonesia's Life Reef Fish

    Creator:
    Fauzi, Akhmad
    Abstract:
    Fishing for the life reef fish has been an important source of economy both at macro level and micro level. At Macro level, life reef fish for food (LRFF) plays a greater role in increasing export revenue since most of the fish are sold in overseas markets such Hong Kong...

  • Rural community quotas - intentions and impacts

    Creator:
    Hermansen, Oystein and Dreyer, Bent
    Abstract:
    In many fisheries, the harvesting pattern shows considerable intra-year variation. These fluctuations give challenges for downstream firms in value chains where predictability and continuity in the flow of production are important. Seasonal harvesting may well be rational from an economic perspective, as migration patterns can give huge variations in catch...

  • Fishing in a Shallow Lake: A Case for Effort Controls?

    Creator:
    Janmaat, John and Ruijs, Arjan
    Abstract:
    In many situation, fishing activity adversely impacts the state of the marine ecosystem, impacts which feed back to affect fish stocks. Some ecosystems appear to have multiple equilibria and exhibit hysteresis, whereby they can become stuck in low productivity states. We show how adding ecosystem dynamics to a classic fisheries...

  • Structural changes in the Icelandic fisheries sector - a value chain analysis

    Creator:
    Knútsson, Ögmundur, Klemensson, Ólafur, and Gestsson, Helgi
    Abstract:
    This pilot study maps the structural changes in the Icelandic fisheries sector from 1990 to present, from the general to the specific. The background is the radical and substantial changes in the structure of harvesting, production and processing; in the export activities and marketing in Icelandic fisheries. The main characteristics...

  • Fisheries induced evolution. A review

    Creator:
    Reithe, Siv and Primicerio, Raul
    Abstract:
    Age and size at maturity are key life-history traits in a fish stock. At the individual level, age and size at maturity affect fecundity, growth and survival. At the population level these factors interact to affect the age and size distribution, the population dynamics and the productivity of the stock....

  • Capacity Measurement and Policy Simulation of Fishery Industry in Japan

    Creator:
    Managi, Shunsuke
    Abstract:
    The expansion of fishing capacity is one of the most pressing problems facing many fisheries around the world. Excess capacity arises when a high number of vessels enter the fishery, and these vessels are employed to exploit the available fish stocks beyond a target level of yield. The lack or...
