Do species interactions and stochasticity matter to optimal management of multispecies fisheries?
(Discussion paper;2012:1, Working paper, 2012-01)
The multispecies fisheries management looks at a bigger picture in addressing the long-term consequences of present decisions. This implies an ecosystem management that includes a number of species and their physical, ...
A hit-and-run interloper model for a regional fisheries management on the high sea
(Discussion paper2002:10, Working paper, 2002-07)
The 1993 U.N. Straddling Stock Agreement prescribes a multi-national organizational structure for management of an exploited marine fish stock, one whose range straddles both .Extended Economic Zones. (EEZs) and high seas ...
Data assimilation into biomass dynamics models : a Monte Carlo simulation experiment
(Discussion paper2001:16, Working paper, 2001)
In this paper, we use a variational data assimilation method to fit biomass dynamics models to simulated data. The method is the variational adjoint technique in which a cost function measuring the distance between the ...
Dynamiske CO2-avgifter : en modell med endogent bestemt avgiftsperiode
(Discussion paper2003:21, Working paper, 2003-12)
A perturbation approach on a class of optimal control problems, unifying the pontryagin and dynamic programming approach
(Discussion paper2000:15, Working paper, 2000-06)
This article consider special ways of solving time dependent (non-autonomous) systems. Different types of time-dependent Optimal Control Problems in the setting of a Hamiltonian Formulation, are considered and the emphasis ...
A simple approach to global optimal feedback solutions : with emphasize on certain management problems in economics
(Discussion paper2001:17, Working paper, 2001-06)
Dynamic optimization problems covers a great class of problems in management science and technology. The classical problem formulations being the variational approach as in classical mechanics, like Hamilton's principle ...
Fish wars on the high seas : a straddling stock competition model
(Discussion paper2001:8, Working paper, 2001-04)
The post World War II era saw the development of powerful self-contained fishing fleets, so-called distant-water fleets (DWFs), which roamed the worlds oceans, seeking out rich harvesting targets wherever they might be ...
More is less : the tax effects of ignoring flow externalities
(Discussion paper2000:21, Working paper, 2000-11)
Using a model of nonlinear decay of the stock pollutant, and starting from the same initial conditions, the paper shows that a tax that only corrects for stock externalities can, at the steady state, be higher than a tax ...
A survey and analysis of outsourcing in East China
(Discussion paper2009:5, Working paper, 2009-05)
The aim of this study is to investigate whether outsourcing activities in east china are associated with a theoretical framework derived from the literature. By the methodology of Statistics Package for the Social Science ...
Continuous harvesting costs in sole-owner fisheries with increasing marginal returns
(Discussion paper2009:6, Working paper, 2009-09)
We develop a bioeconomic model to analyze a sole-owner fishery with fixed costs as well as a continuous cost function for the generalized Cobb-Douglas production function with increasing marginal returns to effort level. ...
