  • 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 US salmon market : demand characteristics and price linkage

    Creator:
    Clay, Patty L. and Gordon, Daniel V.
    Abstract:
    In this paper, we study the short run price dynamics of imported fresh, farmed Atlantic and Pacific salmon on US regional markets. An Error Correction framework is used to specify a short run model. The results show a substitute relationship among the different salmon species in that an adjustment process...

  • Climate, Competition and The Management of Shared Fish Stocks

    Creator:
    Miller, Kathleen, Munro, Gordon R., and Bjorndal, Trond
    Abstract:
    Long-term climate regime shifts have profound and persistent impacts on ocean temperature and circulation patterns, and on the dynamics of marine fish populations -- affecting abundance, growth and migratory behavior. Such shifts are a particularly important source of uncertainty for marine fisheries. Here, we argue that climate regime shifts can...

  • Over-capacity, Regulation and Rent: A Norwegian Case Study

    Creator:
    Asche, Frank, Bjorndal, Trond, and Gordon, Daniel V.
    Abstract:
    Traditional fisheries management schemes provide fishermen with incentives to maximise their individual share of the catch, while individual vessel quota management schemes change incentives to maximise profits from their individual share of the catch. The way that one models the fishermen’s optimisation problem in empirical studies should reflect the changed...

  • Virtual Populations: A New Arrow in The Quiver of Rights-Based Fishing

    Creator:
    Lee, Jungsam and Gates, John M.
    Abstract:
    Quota management systems (QMS) provide faith-based incentives for individual quota holders to conserve the resource voluntarily; quota holders expect the system to work and to be enforced and their expectations are usually realized despite imperfect incentives and significant enforcement burdens. Even with QMS there is never an individual incentive to...

  • Harvest Strategies for a Transboundary Resource: Georges Bank Haddock

    Creator:
    Thunberg, Eric M., Fulcher, Charles M., and Brodziak, Jon K. T.
    Abstract:
    The eastern Georges Bank haddock resource is shared and managed by the U.S. and Canada through a transboundary resource sharing agreement. This agreement includes an annual process for joint stock assessment, setting of a TAC, and harvest shares for each country. The resource sharing agreement provides a mechanism for establishing...

  • Can Stochasticity Cause Overcapacity in a Pure Open Access Fishery?

    Creator:
    Rust, Steven, Yamazaki, Satoshi, and Jennings, Sarah
    Abstract:
    Overcapacity remains a major issue in world fisheries. The specific conditions that give rise to overcapacity in the pure open access fishery remain unclear, however the non‑malleability of capital is widely regarded as a necessary condition for the accumulation of excess harvesting capacity. In the process of fisheries collapse known...

  • Toward a New Paradigm of the Fisheries Management

    Creator:
    Kawasaki, Tsuyoshi
    Abstract:
    Fisheries management has been carried out on the assumption that a fish population is in equilibrium with the fishing effort under the average environmental conditions and hence there must be a maximum sustainable yield (MSY). However, since the simultaneous rise and fall of the interdecadal and global scale of sardine...

  • Fish, Floods, and Farmers: The Joint Production of Ecosystem Services on a Working Landscape

    Creator:
    Garnache, Cloe
    Abstract:
    This paper examines the tradeoffs between the production of crops and habitat for juvenile salmon, through flood events, on the Yolo Bypass floodplain. I investigate how changes in the fishery management institution affect the economic returns to fish habitat. To understand how habitat provision affects the economic surplus of the...
