  • Climate Change, ENSO Frequency and Intensity, and the Gulf of Mexico Headboat Fishery

    Creator:
    Carter, David and Letson, David
    Abstract:
    Recent results from a vector error correction (VEC) analysis indicate that El Niño-Southern Oscillation (ENSO) events appear to affect both red snapper landings and effort in the Gulf of Mexico headboat fishery (Carter and Letson 2005). A key finding is that the outcome of policy changes can vary depending on...

  • An Approach To Managing Fisheries When Weak And Strong Stocks Mix

    Creator:
    Tomberlin, David
    Abstract:
    When weak and strong fish stocks are caught in the same fishery, managing for the protection of the weak stock may result in foregone economic benefits from harvest of the strong stock, while managing for the strong stock may result in overfishing of the weak stock. A particular complication arises...

  • Economic Results of the Australian National Recreational Fishing Survey

    Creator:
    Campbell, David
    Abstract:
    Recreational fishing is a compound activity that includes the expectancy and catching of fish. The Australian national recreational fishing survey provides catch and economic data for this activity for the 12 months May 2000 to April 2001. In addition to catch behavioral data, the survey provides economic data for that...

  • Estimating the Economic Impact of the Steller Sea Lion Conservation Area: Developing and Applying New Methods for Evaluating Spatially Complex Area Closures

    Creator:
    Haynie, Alan and Layton, David
    Abstract:
    Economists and biologists have recognized that spatial and temporal area-closures may provide an effective means of managing the impact that fisheries have on one another and upon threatened species. To date, however, little work has been done to estimate the economic impact of protected areas on commercial fishing. One significant...

  • Economic Performance of Fishers: Stochastic or Chaotic?

    Creator:
    Pascoe, Sean and Whitmarsh, David
    Abstract:
    Economic performance of different fleet segments varies considerably from year to year, with some segments experiencing increased profitability while others experience decreased profitability. This variation is generally considered to be a consequence of the stochasticity in the industry. However, there is growing evidence that fisheries may not be as stochastic...

  • Algolculture

    Creator:
    Caswell, Margaret and Zilberman, David
    Abstract:
    U. S. agriculture is at a crossroads. The value of traditional agricultural exports has fallen while imports have increased. Concerns about the environmental impacts of current agricultural practices threaten profitability. As O'Connell (1989) pointed out in Choices , one answer to U. S. farm problems might be found in the...

  • Fisheries in a Complex System

    Creator:
    Finoff, David and Tschirhart, John
    Abstract:
    An important subset of natural resource management addresses preserving and/or harvesting biological resources. Examples are policies that derive from the Endangered Species Act including habitat conservation plans, the U.S. Forest Service’s logging practices, and fishery management councils’ decisions regarding catches. To understand the effectiveness of management policies requires an understanding...

  • Solving Real Options Models of Fisheries Investment When Salvage Value Is Difficult to Estimate

    Creator:
    Tomberlin, David and Bosetti, Valentina
    Abstract:
    Real options models arguably provide a useful framework for understanding individual fishermen's investment decisions, which play an important role in fisheries management issues ranging from capacity reduction to stock assessment. While these models appear to predict actual behavior reasonably well, one important difficulty in applying them is that the salvage...

  • Simulation Model Evaluation of Some Fisheries Balance Indicators

    Creator:
    Sampson, David and Scott, Robert
    Abstract:
    Chronic overcapacity has been identified as a major cause of the overfishing of Europe’s fish stocks and the poor economic performance of the European fishing fleets. Mechanisms are needed to ensure that the capacity of European fishing fleets remain proportionate to available fish stocks. To that end, the European Commission...
