Abstract or Summary
  • By using harvest data for a North East Arctic Cod Fishery in the Barents Sea for the years 1971-1985 a monthly and daily dimensional harvest function is estimated. The seasonal factors are investigated using dummy variables. The results indicate that the seasonality is embodied in the catch ability coefficient of the harvest function, and not in the catch effort elasticity. However the impact of multicollinarity is to be well aware of when discussing the dummy results. The catch effort elasticity is estimated well above unity for most specifications. The catch stock elasticity is estimated in the range of 0.18 - 0.23 for different specifications. In the analysis we use panel data methods like standard random and fixed effects panel estimation but we also correct for first order autocorrelation in the error term. However, the catch biomass elasticity turns out to be negative and significant when correcting for autocorrelation.
