Do species interactions and stochasticity matter to optimal management of multispecies fisheries?
Poudel, Diwakar; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar; Kvamsdal, Sturla Furunes (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, ... -
Does stochasticity matter? : dynamic pigouvian taxation in an uncertain environment
Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, Working paper, 2004-04)The effects of discounting, stochasticity, non-linearities and maximum decay upon an optimal corrective tax are analyzed using stochastic dynamic optimization. Optimal corrective taxes are derived as explicit feedback ... -
Dynamic cournot-competitive harvesting of a common pool resource
Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Working Paper, Working paper; Working paper, 2003-01)A variant of the classical harvesting game, where a number of competing agents simultaneously harvest a common-pool natural resource, is analysed. The harvesting at each time is a Cournot competition. The critical assumption ... -
Dynamiske adaptive miljøavgifter
Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Rapport, Research report, 2001-04)Optimale CO2-avgifter finnes som en feedback-relasjon ved hjelp av dynamisk optimering. Objektfunksjonen er å maksimere velferden som består av summen av konsument- og produsentoverskudd i markedet for fossilt brennstoff ... -
Economic evaluation of alternative harvesting strategies for fish stocks
Steinshamn, Stein Ivar (Doctoral thesis, 1992) -
Economic evaluation of the fisheries policies in Denmark, Iceland and Norway : some performance indicators
Arnason, Ragnar; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar; Vestergaard, Niels (Working Paper, Working paper; Working paper, 2002-08)The economic efficiency of the Danish, Icelandic and Norwegian cod fisheries is examined. For this purpose nonlinear aggregate models of these three fisheries are constructed. A particular mathematical approach to calculate ... -
Economic feasibility of microalgae as a source of biodiesel : Techno-economic and sustainability analyses
Feron, Solène (Master thesis, 2021)Microalgae receive rising attention because of their capacity to generate biofuels. Cultured either in ponds or photobioreactors, they have a high growth rate, occupy smaller cultivation land area than other biofuel-generating ... -
Electricity in Senegal: en analysis into potential strategies to increase electrification rates
Rauseo, Alexandra (Master thesis, 2019)Senegal is a West African country dependent on imported fossil fuels for power generation. The population of Senegal is 15.85 million, with the urban and rural electrification rates at 87.7 and 38.3, respectively. Over ... -
En oversikt og vurdering av skatter og avgifter i fiskeflåten
Steinshamn, Stein Ivar (Rapport, Research report, 2008-06)Formålet med denne rapporten er å gi en mest mulig fullstendig oversikt over skatte- og avgiftstrykket i den norske fiskeflåten med hovedvekt på gebyrer og særavgifter. Utredningen tar for seg fem aspekter: 1. Definisjon ... -
En prinsipiell drøfting av effekter for norsk sjømateksport av reduserte handelsbarrierer
Steinshamn, Stein Ivar; Asche, Frank; Tveterås, Ragnar (Rapport, Research report, 2001-06)Norge antas å ha klare offensive interesser relatert til handel med fisk både generelt, og spesielt i forhold til WTO. I denne rapporten ser vi først på en del prinsipielle sider ved handel med vekt på begreper som komparative ... -
Estimation of biological and economic parameters of a bioeconomic fisheries model using dynamical data assimilation
Ussif, Al-Amin M.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, Working paper, 2000-05)A new approach of model parameter estimation is used with simulated measurements to recover both biological and economic input parameters of a natural resource model. The procedure efficiently combines time series of ... -
Estimation of biological and economic parameters of a bioeconomic fisheries model using dynamical data assimilation
Ussif, Al-Amin M.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Working Paper, Working paper; Working paper, 2002-03)A new approach of model parameter estimation is used with simulated measurements to recover both biological and economic input parameters of a natural resource model. The data assimilation technique is the variational ... -
Fish wars on the high seas : a straddling stock competition model
McKelvey, Robert W.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, 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 ... -
Fish wars on the high seas : a straddling stock competition model
McKelvey, Robert W.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Working Paper, Working paper; 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 world’s oceans, seeking out rich harvesting targets wherever they might be ... -
Fish wars on the high seas : erecting economic barriers to entry
McKelvey, Robert W.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Working paper, Working paper; Working paper, 2000-10)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 ... -
Fisheries management under irreversible investment : does stochasticity matter?
Poudel, Diwakar; Sandal, Leif Kristoffer; Kvamsdal, Sturla Furunes; Steinshamn, Stein Ivar (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 ... -
Fishermen facing headwinds : a quantitative approach to evaluating fishing grounds and measuring the impact of offshore wind on the commercial fishing industry
Falck-Pedersen, Magnus; Skjæveland, Folke M. Skofteland (Master thesis, 2020)In this thesis, we investigate the impact of developing offshore wind farms in Træna on the local community and the fleet operating in the respective areas. In particular, we evaluate the catch value within each offshore ... -
The future of the energy supply sector and the role of nuclear power : what is the real price of energy?
