Abstract or Summary
  • 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 in the second stage. Realizing the estimated stock index contains measurement error, the simulation-extrapolation method is used to correct bias. From this, all parameters as well as the latent stock can be identified. This method is also applied to the reef-fish fishery in the northeastern Gulf of Mexico. The traditional method, which uses catch-per-unit-effort (CPUE) as a proxy and is ignoring measurement error, significantly overstates the carrying capacity and the maximum sustainable yield.
