  • Estimating a Generalized Gordon-Schaefer Model with Heterogeneous Fishing Data

    Creator:
    Zhang, Junjie and Smith, Martin D.
    Abstract:
    This paper proposes a two-stage method to estimate a generalized Gordon-Schaefer model, using heterogeneous fishing data in the logbook. A Cobb-Douglas production function is consistently estimated in the first stage by means of the ‘within period estimator’. A stock index is constructed and used to estimate the logistic growth model...

  • The Economic Cost of Ignoring Fishery Induced Evolution

    Creator:
    Faig, Amanda D.
    Abstract:
    Ecologists warn that the rapid evolution occurring as a result of high-intensity commercial fishing could have potentially disastrous economic and ecological effects. The evolution of economically relevant life-history traits in fish, which can occur due to the harvesting pressure from commercial fisheries, can irreversibly diminish fisheries yields and ecological services....

  • Bioeconomic Modelling of the Namibian Rock Lobster

    Creator:
    Steenkamp, Z. D.
    Abstract:
    The purpose of this study is aimed at developing a simple bioeconomic model of the Namibian rock lobster fishery, with the main objective being to incorporate economics into fisheries management in order to estimate the potential economic benefits that could accrue to the fishery given efficient management. The complex nature...

  • Limited Entry Licensing and Adaptive Management: Insights from Duration Modeling

    Creator:
    Smith, Martin D.
    Abstract:
    Although many fisheries around the world have long required explicit licensing for fishery participants, the use of limited entry licensing to control fishing effort has become a common practice in the last two decades. In contrast to Individual Fishing Quotas (IFQs), limited entry is only a step towards rights-based management....

  • Can We Stabilize Fisheries' Benefits from a Fluctuating Stock? A Bioeconomic Assessment of The Pacific Whiting Fishery

    Creator:
    Ishimura, Gakushi, Huppert, Daniel D., and Punt, Andre E.
    Abstract:
    Pacific whiting (Merluccius productus) is one of the most commercially valuable fish species in the Pacific coast groundfish fishery, experiences extreme variability in annual recruitment. This variability causes fluctuations in stock abundance and subsequent catch and economic benefits. This study develops a stochastic bioeconomic model of the Pacific whiting fishery...

  • Are Catfish Inspections an Administrative Trade Barrier to Imported Fish?

    Creator:
    Davidson, Kelly and Kropp, Jaclyn D.
    Abstract:
    The Agricultural Act of 2014 (Public Law 113-79) amended legislation regarding the U.S. catfish inspection program to include “all fish of the order Siluriformes,” encompassing imported species: basa, tra, and pangasius. Furthermore, the amendment finalized the transition of catfish and catfish-like product inspection responsibilities to the USDA Food Safety and...

  • State Dependence in Modeling the Spatial Behavior of Renewable Resource Users

    Creator:
    Smith, Martin D. and Wilen, James E.
    Abstract:
    In marine resource management, spatial policy instruments, including Marine Protected Areas, are becoming increasingly important. The economic motivation for spatially explicit policy is that renewable resources generate, in addition to the conventionally recognized incentives to over-harvest in the face of insecure property rights, spatial externalities that distort the spatial distribution...

  • Discrete Choice Modeling of Landings Locations

    Creator:
    Asche, Frank, Smith, Martin D., and Birkenbach, Anna
    Abstract:
    Interest in sustainable fishing communities suggests the need to understand fishermen’s decisions about where to land fish. In this paper, we apply techniques used extensively to analyze fishing location choices to study landings location choices. We analyze detailed microdata from Norwegian groundfish vessels that land fish in fourteen different ports...

  • Knowledge is Power? The role of market information in value creation by developing country aquaculture producers

    Creator:
    Kelling, Ingrid and Young, James A.
    Abstract:
    International seafood trade takes place through value chains that link production in developing countries to developed country markets. As a result of the emergence of the global value chain analytical framework from the political economy of development (and underdevelopment) approach, value chain analysis has traditionally maintained a production orientation to...
