A recreational sector is added to a standard commercial fishing optimal
control model to identify public decision variables that should be considered
when determining optimal population levels and allocating harvestable fish
between sport and commercial users. Both linear and nonlinear models are
presented. A predator-prey relationship is also considered. Results derived
from the models indicate that shortcomings exist with current economic inputs
to policy making because of failure to consider relevant bioeconomic
relationships. Future research topics to remedy this are discussed.

"Contingent Valuation of Environmental Assets: Comparisons with a
Simulated Market." Draft report.
The evidence to support the view that people confronting a contingent
valuation mechanism do not have well developed beliefs about how they would
behave in real markets for environmental assets comes primarily from an
experiment involving Wisconsin goose hunting permits. These permits were
evaluated using several CV mechanism and a travel cost model. They were also
evaluated in a "simulated market" where permit holders were offered real money
not to hunt. The results show that contingent values could easily be in error
by 50 percent or more. After describing the experiment and its results, the
remainder of the paper explores the reasons for these errors with particular
emphasis on the artificiality of CV mechanisms. Several conclusions emerge,
including one particularly interesting hypothesis: Our results and those of
some other studies seem to show that CV mechanisms tend to underestimate
willingness to pay and overvalue environmental assets when the criterion is
willingness to accept compensation.
Bjorndal, Trond (1988). "The Optimal Management of North Sea Herring."
Journal of Environmental Economics and Management, 15:9-29.
A discrete time dynamic bioeconomic model for a fish resource is
developed. The objective is maximization of discounted net revenues subject
to changes in stock size. The model of population dynamics is described by a
delay-difference equation. Natural growth and recruitment are related to
stock size, with recruitment taking place with a time lag. Conditions
characterizing the optimal stock level are derived. The model is applied to
North Sea herring. Estimates of the optimal stock level are given, and
optimal trajectories derived. Due to the schooling behavior of herring, it is
shown that open access amy cause stock extinction.

Resource Economics, 5(2):139-159.
This paper analyzes the optimal harvesting of farmed fish. A biological
model for a year class of fish is specified. Output price and costs are added
to constitute a bioeconomic model. The effects of economic and biological
parameters on optimal harvesting are analyzed. Examples of optimal harvesting
for salmon and turbot are given.
Bjorndal, Trond (1989). "Production in a Schooling Fishery: The Case of
the North Sea Herring Fishery." Land Economics, 65(1):49-56.
This paper undertakes an empirical analysis of the harvest function for
the North Sea herring fishery. The empirical results indicate that there is a
rising marginal product to the variable input in the fishery. Fishery
regulations that were in force, including total quotas and closed seasons, are
found to be either ineffective or causing boats to operate inefficiently.
