Economic Performance of fishers: Stochastic or Chaotic?
By Sean Pascoe
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 as generally thought. In this paper, a spatial bioeconomic model is developed of a multi-species multigear fisher, which assumes individual profit maximising behaviour. It is shown that interannual variations in profits are a function of the spatial behaviour of the fishers, which tends to vary chaotically over time.
