Catch, Stock Elasticity, and an Implicit Index of Fishing Effort
Economists are interested in the relationship between fishing effort and stock size, and the impact on catch levels. The interest lies in the stock elasticity where it is thought that for pelagic fish species it is close to zero and for demersal fish stocks closer to one. We statistically model and...

Economists are interested in the relationship between fishing effort and stock size, and the impact on catch levels.
