Fisheries management under irreversible investment : does stochasticity matter?
(Discussion paper;2011:20, Working paper, 2011-11)
We present a continuous, nonlinear, stochastic and dynamic model for capital investment in the exploitation of a renewable resource. Both the resource stock and capital stock are treated as state variables. The resource ...
A maximum entropy approach to the newsvendor problem with partial information
(Discussion paper;2011:14, Working paper, 2011-08)
In this paper, we consider the newsvendor model under partial information, i.e., where the demand distribution D is partly unknown. We focus on the classical case where the retailer only knows the expectation and variance ...
Stackelberg equilibria in a multiperiod vertical contracting model with uncertain and price-dependent demand
(Discussion paper;2012:2, Working paper, 2012-02)
In this paper, we consider Stackelberg games in a multiperiod vertical contracting model with uncertain demand. Demand has a distribution with a mean and variance that depend on the current retail price, and this ...
The ensemble Kalman filter in bioeconomics
(Discussion paper;2012:5, Working paper, 2012-05)
We demonstrate the power of the Ensemble Kalman Filter in specifying ecosystem models ideal for bioeconomic analysis. Bioeconomic analysis requires models to be relatively simple, but models must still capture the nature ...
Analyzing risk of stock collapse in a fishery under stochastic profit maximization
(Discussion paper;2012:4, Working paper, 2012-04)
In commercial fisheries, stock collapse is an intrinsic problem caused by overexploitation or due to pure stochasticity. To analyze the risk of stock collapse, we apply a relatively simple Monte Carlo approach which can ...
A stitch in time saves nine : the costs of postponing action in climate policy
(Report;2011:16, Research report, 2011)
The main purpose of this report is to investigate the effects of postponing implementation of a carbon tax assuming that externalities associated with climate change and global warming is real. Failing to internalize these ...
