Fishing Productivity and its Relation to Management Regimes
Summary
Although both economic and biological performance have long been important
focal points in fisheries economics, traditional productivity measurement
has historically played an ancillary role. In the past two decades, however,
it has been increasingly recognized that modeling and measuring production
processes in fisheries is a key to understanding, and ultimately correcting,
imbalances resulting from market failures and biological constraints.
Production models allow one to track standard measures of economic performance
and to analyze how such measures change in response to regulatory and
biological variations. In this paper we add to the currently limited literature
on productivity in fisheries, by estimating productivity and its components
for the Bering Sea and Aleutian Islands pollock fishery. In particular,
we analyze changes in productivity that occurred for catcher-processors
after introduction of cooperatives through the American Fisheries Act.
We also incorporate measures of discarded bycatch in our model so that
productivity measures embody externalities generated by pollock harvesting
operations. Our approach is less restrictive than the existing fishery
productivity studies in that we relax assumptions regarding constant returns
to scale, marginal cost pricing, Hicks-neutrality, and homothetic separability.
This work is being conducted jointly with Catherine Morrison Paul at the
University of California, Davis.
