  • Fishery Management When Biological and Economic Disturbances Are Correlated

    Creator:
    Kennedy, Chris J.
    Abstract:
    Economists studying the management of fisheries have universally assumed disturbances affecting harvest costs are unrelated to disturbances affecting biological growth. This paper gives examples of commercially valuable species that are impacted reproductively and behaviorally by a single environmental variable (e.g., temperature), leading to correlated disturbances in current marginal harvest costs...

  • The Stability of Rent Maximization in the Western and Central Pacific Fishery

    Creator:
    Kennedy, John and Hannesson, Rögnvaldur
    Abstract:
    The potential for achieving sustainable and efficient harvesting of three species of migratory tuna in the Western and Central Pacific Ocean is examined. The stocks reside in exclusive economic zones (mainly those of Pacific island countries) and in the high seas. Most harvesting is carried out by distant water fishing...

  • Thin Wholesale Markets and Direct Marketing in Renewable Resource Exploitation

    Creator:
    Kennedy, Chris J. and Scott, Steve
    Abstract:
    The ex-vessel supply chain for fisheries has been recognized as an important determinant of value generation. In recent years, as the retail demand for fresh seafood products has increased, many independent fishermen have bypassed thin, monopsonized, or otherwise inferior wholesale markets by engaging in implicit or explicit fixed-output contracts with...

  • Bioeconomic Modeling and Management of the Southern Bluefin Tuna Fishery

    Creator:
    Campbell, Harry and Kennedy, John
    Abstract:
    The paper reviews the management and bioeconomic modeling of the Southern Bluefin Tuna stock. It describes two studies using simultaneous, non-cooperative, three player games to predict revenue and stock outcomes generated by a deterministic, discrete, age-structured model of the SBT population. Two versions of the model, corresponding to biological and...

  • Landing Fees Versus Fish Quotas

    Creator:
    Hannesson, Rognvaldur and Kennedy, John
    Abstract:
    The relative efficiency of landing fees versus quota controls to achieve given escapement levels is examined. The criterion is profit per year over a given time horizon. The model employed is a discrete version of the logistic model where growth is influenced by a random variable. Simulations are used to...

  • Support to Fisheries: Levels and Impacts

    Creator:
    Martini, Roger
    Abstract:
    The OECD has been collecting information on fisheries policies for many years. The Fisheres Suppor Estimate (FSE) database represents the latest version of its fisheries policy inventory and classification system. This database contains information on policies in 33 countries (representing about half of global fisheries landings) totalling USD 13 billion...

  • Optimal Batch Lengths for Barramundi Farming Under Seasonal Variations: A Dynamic Programming Approach

    Creator:
    Rupasinghe, Jagath W. and Kennedy, John O.S.
    Abstract:
    Key decision variables in aquaculture management are stocking level, feeding schedule, temperature control and batch length. In many management problems with an infinite planning horizon, the aim is to find the batch length which results in maximum return if the same batch length applies to all future batches. This may...

  • The Relative Efficiency of Fees and Quotas Applied to Fisheries Under Different Types of Uncertainty

    Creator:
    Kennedy, John O. S. and Hannesson, Røgnvaldur
    Abstract:
    Quotas rather than landing fees are widely used for reducing the output of fisheries below open-access levels. One reason may be that quotas are perceived as a more reliable instrument for controlling total catch. However, whilst under certainty fees and quotas can be set each season to achieve the same...

  • Effects of Catfish and Crawfish Imports on U.S. Domestic Prices

    Creator:
    Kennedy, P. Lynn and Lee, Young-Jae
    Abstract:
    Recent increases in imports of catfish and crawfish have caused concern as to their impact on domestic prices. This study identifies the linkages between imports of these goods and U.S. producer prices. Increases in imports of catfish are shown to decrease related domestic prices. However, recent trends show a simultaneous...

  • Conservation and Optimum Utilization of Southern Bluefin Tuna

    Creator:
    Campbell, H. F., Kennedy, J. O. S., and McIlgorm, A.
    Abstract:
    The paper predicts the outcomes of alternative management scenarios for the Southern Bluefin Tuna (SBT) fishery over the next twenty years. Two criteria are used to characterize outcomes: economic efficiency as measured by the present value of fishery rent generated; and conservation as measured by the predicted size of the...
