  • Discontinuous Sustainable Yield: The Exception or the Rule?

    Creator:
    Arnason, Ragnar
    Abstract:
    The sustainable yield function is a favoured tool in fisheries policy making. Normally, this function is drawn as a continuous curve in effort-yield space. This means that sustainable yield (harvest) is gradually reduced to zero as fishing effort increases. This, however, does not have to be the case. The sustainable...

  • The Artisanal Hilsa Fishery: economically Efficient Fisheries Policy

    Creator:
    Mome, Masud Ara and Arnason, Ragnar
    Abstract:
    The hilsa shad (Tenualosa ilisha) fishery is by far the largest single species fishery in Bangladesh. In this paper, a simple bio-economic year-class based model is developed to describe the fishery and examine its properties. With the help of this model, the optimum sustainable yield of the fishery is calculated...

  • Global Trends in Capture Fisheries, With an Estimate of Global Losses in Marine Fisheries Resource Rents

    Creator:
    Willmann, Rolf, Arnason, Ragnar, Franz, Nicole, and Kelleher, Kieran
    Abstract:
    Trends in key fisheries indicators are presented to provide the context for a profile of the economic health of the world's marine fisheries. Estimates of the economic value of global marine fishery production and costs of production are used as inputs to an economic model to derive a range of...

  • Stock and (possibly) path dependent technologies

    Creator:
    Arnason, Ragnar and Willmann, Rolf
    Abstract:
    According to conventional economic wisdom the economically more efficient technology will always outcompete the less efficient. This hypothesis has usually been taken to hold for the exploitation of common pool renewable natural resources such as fish stocks. This paper claims that, while this is not necessarily false, it may be...
