• Fragmented property rights, R & D and market structure 

      Konrad, Kai A.; Clark, Derek J. (Working paper; Arbeidsnotat, 2005-04)
      Fragmented property rights can be a factor that limits firms’ willingness to invest in the development and commercialization of new products. This paper studies the interaction between markets for products and markets for intellectual property rights (patents) where product innovation requires several complementary patents, each of which is obtained as the result of a patent race. We show that ...
    • Tournaments with multi-tasking 

      Clark, Derek J.; Konrad, Kai A. (Working paper; Arbeidsnotat, 2005-08)
      The standard contest model in which participants compete in a single dimension is well understood and documented. In this paper we propose an extension in which competition ensues in several dimensions and a competitor that wins a certain number of these is awarded a prize. We look at the design of this contest from the point of view of maximizing effort in the contest (per dimension and totally), ...
    • Why potential entry may increase platform sponsors' profit 

      Foros, Øystein; Sand, Jan Yngve; Kind, Hans Jarle (Working paper; Arbeidsnotat, 2005-09)
      In this paper we analyze the incentives for platform sponsors to open up their networks for independent rivals. We show that open access may increase the platform sponsors’ profit levels and enhance quality improving investments.
    • How to distribute information 

      Sirnes, Espen (Working paper; Arbeidsnotat, 2005-10)
      In this paper a difficult question is answered with a surprisingly simple answer. A monopolist who possesses nested information can earn money from selling it at different levels of precision to investors. The problem is to maximize profits by choosing the optimal distribution of information among the investors. I show that, the optimal distribution is to give all informed investors the same ...
    • License fees. The case of Norwegian salmon farming 

      Roland, B.-E.; Färe, Rolf; Grosskopf, Shawna; Weber, William L. (Working paper; Arbeidsnotat, 2005-10)
      The Norwegian salmon farming industry is one of the most important Norwegian export industries. The industry is also regulated to secure balanced and sustainable development. Current regulatory practice consists of licensing access to sea water. The government recently set an upper bound on the license fees; the purpose of our paper is to estimate the shadow price of the property right to determine ...
    • Water demand and the urban poor. A study of the factors influencing water consumption among housholds in Cape Town, South Africa 

      Jansen, Ada; Schulz, Carl-Erik (Working paper; Arbeidsnotat, 2006-01)
      Water demand management is a key focus area for most water managers and even more so in developing countries. Improved access to water is important to the poor. Water scarcity makes efficient management even more urgent and it creates more conflicts in water distribution. Different policies have been introduced to ensure a water management system that cares for the poor, among them the Increasing ...
    • Efficiency in complementary partnerships with competition 

      Sand, Jan Yngve (Working paper; Arbeidsnotat, 2006-01)
      This paper investigates a market with strictly complementary inputs, with a particular emphasis on how efficiency can be implemented when the productive firms undertake unobservable effort. It is shown that simple linear sharing rules cannot implement socially optimal effort, but a modified linear sharing rule can implement the first-best outcome and a restricted linear sharing rule can be used ...
    • Nature reserves as a bioeconomic management tool. A simplified modeling approach 

      Flåten, Ola; Mjølhus, Einar (Working paper; Arbeidsnotat, 2006-02)
      This paper demonstrates analytically how a nature reserve may protect the total population, realize maximum sustainable yield (MSY), maximum economic yield (MEY) and consumer surplus (CS) and how this depends on biological growth, migration, reserve size and economic parameters. The pre-reserve population is assumed to follow the logistic growth law and two post-reserve growth models are discussed. ...
    • Aquaculture-fisheries interactions 

      Mikkelsen, Eirik (Working paper; Arbeidsnotat, 2006-02)
      Assuming externalities from aquaculture to fisheries, we use a Verhulst-Schaefer model of fish population-dynamics and production, coupled with an aquaculture production model, to investigate effects on open-access and rent-maximising fisheries. Externalities are modelled by letting carrying capacity, intrinsic growth rate or catchability coefficient in the fishery depend on aquaculture production. ...
    • A note on the ecological-economic modelling of marine reserves in fisheries 

      Armstrong, Claire W. (Working paper; Arbeidsnotat, 2006-03)
      This paper gives an overview of bioeconomic modelling of marine reserves, and illustrates how economists have responded to the modelling results found in the ecological literature. The economic analysis is shown to be far more pessimistic with regard to the potential of marine reserves as a fisheries management tool, than what one finds in the purely ecological analysis, the reason being the ...
    • Prestasjonsmåling av Volvoforhandlerne i Norge. En DEA analyse basert på kundetilfredshet og finansiell prestasjon 

      Angeltvedt, Halvor (Master thesis; Mastergradsoppgave, 2006-05-15)
      I denne oppgaven analyseres ytelsen til Volvo forhandlerne i Norge for årene 2002, 2003 og 2004 ved hjelp av DEA metoden. Ytelsen måles i kundetilfredshet og finansiell prestasjon. I tillegg søkes det å belyse noen viktige spørsmål. Hva forklarer spredningen i kundetilfredshet? Er det en sammenheng mellom kundetilfredshet og finansiell prestasjon? Og hvilke forhandlere bør brukes som benchmark for ...
    • Effektivitet og produktivitet i norsk matfisknæring for perioden 1996-2003 målt ved bruk av DEA og MPI 

      Lagesen, Marte Punsvik; Sørensen, Helén Marita (Master thesis; Mastergradsoppgave, 2006-05-15)
      I denne oppgaven analyseres effektivitet og produktivitetsutviklingen i norsk matfisknæring i perioden 1996-2003. Produksjonen av laks og ørret har økt betraktelig de siste tiårene. En best mulig utnyttelse av innsatsfaktorene øker produktiviteten ved at produksjonskostnadene synker. For å oppnå et reelt mål på effektivitet og produktivitet for bransjen er det viktig å ta hensyn til alle faktorer ...
    • Is migration important for regional convergence? Comparative evidence for Norwegian and Swedish counties, 1980-2000 

      Westerlund, Olle; Østbye, Stein (Working paper; Arbeidsnotat, 2006-06)
      Regional convergence studies have relied on net migration data in assessing the impact of migration. With heterogeneous labour, the implied symmetrical treatment of immigration and emigration cannot be justified a priori.. Because of heterogeneity among migrants, gross migration flows may lead to considerable interregional redistribution of human capital even when net migration is zero. Moreover, ...
    • Endogenous technology sharing in R&D intensive industries 

      Clark, Derek J.; Sand, Jan Yngve (Working paper; Arbeidsnotat, 2006-06-26)
      This paper analyses the endogenous formation of technology sharing coalitions with asymmetric firms. Coalition partners enjoy perfect spillovers from technology advancements by their coalition partners, but each firm determines its R&D investment level non-cooperatively and there is no co-operation in the product market. We show that the equilibrium coalition outcome is one between the two most ...
    • Fokus på økonomien i de nordiske fiskerier. Sjarkfiske med 8-14,9 m båter i Norge 

      Eriksen, Guri Hjallen; Flåten, Ola (Working paper; Arbeidsnotat, 2006-09)
    • Product and process innovation in a differentiated goods duopoly 

      Clark, Derek J.; Armstrong, Claire W. (Working paper; Arbeidsnotat, 2006-09)
      This paper compares Bertrand and Cournot equilibria in a differentiated duopoly with R&D competition or cooperation, where R&D may affect both unit cost of production and the size of the market. This combination of product and process innovation is shown to allow for the reversal of some results found in earlier models that only look at one of the two types of R&D effects. We find that for a ...
    • Rational benevolence in small committees 

      Clark, Derek J.; Riis, Christian (Working paper; Arbeidsnotat, 2006-09)
      We consider a pie-splitting game involving three committee members. In response to the large literature on sequential procedures in this type of game, we propose an institution that is inspired by auction theory. The (sealed) bids of the players are proposals for a distribution of the pie and are given simultaneously. If any of the bids is preferred to all others in a pairwise comparison (i.e. ...
    • Effektivitetsanalyse av distribusjonsnettet og regional/-sentralenettet til Troms Kraft Nett AS basert på inntektsrammereguleringsmodell foreslått innført i 2007 

      Berglund, Rune Sandmo (Master thesis; Mastergradsoppgave, 2006-12-01)
      Norges vassdrags- og energidirektorat (NVE) regulerer kraftselskapenes monopolvirksomhet (kraftoverføring) gjennom en såkalt inntektsrammeregulering. Inntektsrammeregulering går i grove trekk ut på å sette et tak på hvor mye den enkelte nettvirksomheten kan kreve inn på nettleie fra sine kunder. NVE har foreslått at fra 2007 skal 40 % av inntektsrammen beregnes på bakgrunn av nettvirksomhetenes ...

    • "Påvirket "Science"-saken etterspørselen etter fersk laks i EU" 

      Wiesener, Anders (Master thesis; Mastergradsoppgave, 2006-12-20)
      Oppgaven undersøker om ettervirkningene fra Science-saken reduserte errerspørselen etter fersk laks i EU. Analysen bygger på EUs importkvote fra Norge, Storbritannia, Færøyene, Chile og Canada, samt en medieindex som måler antall artikler publisert med negativ omtale vedrørende giftstoffer i laks i perioden etter Science-saken. For å estimere effekten fra den negative medieomtalen brukes en utvidet ...
