A bioeconomic analysis of an age-structured fish stock continuous in time and age
Steinshamn, Stein Ivar; Golubtsov, Peter (Working paper;2014:15, Working paper, 2015-03)An age-structured bioeconomic model, that is completely continuous in state and time, is developed. To make the model more realistic, a nonlinear recruitment function is introduced and steady state solutions are studied ... -
A comparative analysis of different vehicle configurations : creating a composite indicator to rank vehicle powertrains along multiple dimensions
Sattler, Patrick (Master thesis, 2018)A comparative assessment of internal combustion engine vehicles (ICEVs), battery electric vehicles (BEVs), full hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs) and fuel cell electric vehicles ... -
A stitch in time saves nine : the costs of postponing action in climate policy
Steinshamn, Stein Ivar; Kvamsdal, Sturla Furunes; Sandal, Leif Kristoffer (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 ... -
Adaptive regulation with flow and stock externalities
Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, Working paper, 1998-01)In confronting a consumer good whose production process is associated with both flow and stock externalities, a corrective tax is introduced to restore efficiency. The objective is to maximize social welfare over time when ... -
An approach to adaptive carbon taxes in the presence of global warming
Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, Working paper, 1998-01)The optimal extraction path of fossil fuels and the corresponding corrective tax on extraction are derived when two types of externalities associated with emission of carbondioxide (CO2) are taken into account. The optimal ... -
Assessment of the economic benefits African countries received from their marine resources : three case studies
Eide, Arne; Manning, Peter; Steinshamn, Stein Ivar (Report, Research report, 2003-03)This paper examines the relationship between causality models and cointegration models in testing for price integration and the Law of One Price (LOP). In our review, we show that cointegration models, which allow for ... -
Assimilation of real time series data into a dynamic bioeconomic fisheries model : an application to the Norwegian cod fishery stock
Ussif, Al-Amin M.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, Working paper, 2000-05)This paper combines the new and elegant technique of inverse methods and a Monte Carlo procedure to analyze real data for the Norwegian cod fishery (NCF) stock. A simple nonlinear dynamic resource model is calibrated to ... -
Assimilation of time series data into a dynamic bioeconomic fisheries model : an application to the North East Arctic cod stock
Ussif, Al-Amin M.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Working Paper, Working paper; Working paper, 2003-01)This paper combines the elegant technique of Data Assimilation and a Monte Carlo procedure to analyze time series data for the North East Arctic Cod stock (NEACs). A simple nonlinear dynamic resource model is calibrated ... -
Benefits of stock enhancement: The case of the Iranian kutum fishery
Steinshamn, Stein Ivar; Borujeni, Pezhman Alaei (Working paper;14/14, Working paper, 2014-12)Harvesting of the fish resources as an economic activity, which is strictly tied to biological matters, needs to be modeled proficiently through bioeconomic analysis. In this study, a bioeconomic age-structured model is ... -
Betydningen av fiskeri- og havbruksnæringen i området Lofoten og Barentshavet
Gaasland, Ivar; Steinshamn, Stein Ivar; Vårdal, Erling (Rapport, Research report, 2010-09)Denne rapporten vurderer den samfunnsøkonomiske betydningen av fiskeri- og havbruksnæringen i området Lofoten-Barentshavet under ulike forutsetninger om fremtidige rammebetingelser. Det drøftes også hvilken innvirkning ... -
Business transformation through sustainability : a study of strategic operations and management decision making in the global wine industry.
Brown, Camden (Master thesis, 2017) -
Climate change, poverty and food security : the role of the small-scale fisheries sector
Singh, Balbir; Steinshamn, Stein Ivar (Working Paper, Working paper, 2005-12)Coastal small scale fisheries and communities in the developing countries are vulnerable to global climate change. The consequences occur directly due to the impact of rising temperatures on movement of fish resources and ... -
Coalition Formation with Externalities: The Case of the Northeast Atlantic Mackerel Fishery in a Pre and Post Brexit Context
Toumasatos, Evangelos; Steinshamn, Stein Ivar (Discussion paper;11/17, Working paper, 2017-10-18)In this paper we apply the so-called partition function approach to study coalition formation in the North-east Atlantic mackerel fishery in the presence of externalities. Atlantic mackerel is mainly exploited by the ... -
Combatting Climate Change with Carbon Capture and Storage (CCS) An exploratory study on the implementation of CCS in the Norwegian iron and steel sector.
Jennings, Amanda; Hordvik, Victoria (Master thesis, 2021)Today, Carbon Capture and Storage (CCS) is considered by many as the most credible and costeffective method of combatting global warming and meeting the climate change targets. Despite this, CCS remains a novel technology ... -
