This paper applies a bioeconomic model in order to study different interactions between a harvested renewable resource and a non-renewable resource without commercial value that is negatively affected by the harvesting activity. This enables the analysis of for instance cold water coral habitats and their importance to commercial fish species. The fish is harvested either in a manner that does ...

I sommer har konflikten om havområdene utenfor Lofoten-Vesterålen toppet seg, med sterke utspill fra fiskerhold om seismikkskyting på fiskefelt. Økende bruk av havet til ulike aktiviteter, det være seg fiske eller petroleumsvirksomhet, oppdrett, transport eller turisme, gjør at en bredere forståelse av hvilke verdier havet tilbyr er et viktig innspill i politiske avgjørelser. I dette arbeidet ...

The theme of this report is the regional socio-economic consequences of an extensive oil and gas development in the Barents Sea. The regional focus area includes Finnmark County and Murmansk Oblast. The introductory chapter explains the purpose of the study and the way the work has been done. The next two chapters provide a detailed account of the region and its basic characteristics. The general ...

We consider sequential bargaining between three firms that are all essential in creating a surplus. One of the firms is dominant in the sense that it ultimately decides whether the surplus will be created. The other firms have an incentive to get a large share of the pie for themselves, but leaving enough for the dominant firm that it finds it profitable to create the surplus. Hence, the smaller ...

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. ...

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 ...

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 ...

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. ...

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.

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 ...
