Fragmented property rights, R & D and market structure
(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 ... -
Contingent payments in selection contests
(Working paper; Arbeidsnotat, 2005-04)The early literature on research contests stressed the advantages of a fixed prize in inspiring R&D effort. More recently the focus has moved towards endogenizing the rewards to research activity in these tournament settings, since this can induce extra effort or enhance the surplus of the buyer. We focus on a research contest as a means of selecting a partner for an R&D enterprise, in an ... -
On the economics of ecological nuisance
(Working paper; Arbeidsnotat, 2005-03)This paper analyses the economics of pest and nuisance relating to wild animals. It studies stylised models where wild animals represent a direct nuisance to agricultural production through grazing and crop damage. Such damage is particularly relevant in poor rural communities, where people are dependent on livestock and crop production and at the same time are living close to nature and wildlife. ... -
Marine reserves. A bio-economic model with asymmetric density dependent migration
(Working paper; Arbeidsnotat, 2004-10)A static bioeconomic model of a marine reserve is introduced, allowing asymmetric density dependent migration between the reserve and the fishable area. This allows for habitat or ecosystem differences within and outside a reserve not described in earlier studies. Four scenarios are studied; a) maximum harvest, b) maximum current profit, c) open access and d) maximum sustainable yield (MSY) in ... -
Do incumbents have incentives to degrade interconnection quality in the internet?
(Working paper; Arbeidsnotat, 2003-12)In this paper we analyze the interconnection incentives for firms that have an installed base of customers and that also compete for new customers. We show that the small firm may be harmed in the competition for new customers if the customers in the installed bases are charged a high price, since this makes the large firm more aggressive. It is also shown that the price charged to the installed ... -
Conservation of wildlife. A bio-economic model of a wildlife reserve under the pressure of habitat destruction and harvesting outside the reserve
(Working paper; Arbeidsnotat, 2003-09)Biodiversity is today threatened by many factors of which destruction and reduction of habitats are considered most important for terrestrial species. One way to counteract these threats is to establish reserves with restrictions on land-use and exploitation. However, very few reserves can be considered islands, wildlife species roam over large expanses, often via some density dependent dispersal ... -
Water demand and the urban poor. A study of the factors influencing water consumption among housholds in Cape Town, South Africa
(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 ... -
Distributional effects of marine protected areas. A study of the North-East Atlantic cod fishery
(Working paper; Arbeidsnotat, 2003-01)This paper studies the distributional effects of the implementation of a marine protected area (MPA) for the North-East Atlantic cod stock. A bioeconomic cohort model with two agents targeting different age groups is used to examine how the establishment of an MPA may affect the payoffs to the two main vessel types used to exploit cod, namely, trawlers and coastal vessels. Cooperative and ... -
Aquaculture-fisheries interactions
(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. ... -
Efficiency in complementary partnerships with competition
(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 ... -
How to distribute information
(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 ... -
Kappfiske - problem eller løsning?
(Working paper; Arbeidsnotat, 2005-02)Landingene av torsk i Norge er sterkt sesongvarierte. Fangstene i første halvår i årene 1983- 84 utgjorde om lag 85 % av årets totalfangst. I 1986-88 var andelen sunket til om lag 70 %, mens den steg til 80 % i 1999-2000 og til 90 % i 2001-02. Dette landingsmønsteret for kystflåtens fangster av torskefisk er et resultat av en rekke faktorer; fiskens tilgjengelighet, kvalitet, pris, flåtestruktur, ... -
Excess entry in vertically related markets
(Working paper; Arbeidsnotat, 2003-12)This paper considers the problem of excess entry in vertically related markets when the regulator can regulate market structure and access charges. The endogenous access charge introduces an asymmetry between firms which affects the degree of excess entry. I find that the excess entry result of Mankiw and Whinston (1986) does not generally carry over to vertically related markets. It is shown ... -
Should foreign producers oppose domestic state aid?
(Working paper; Arbeidsnotat, 2004-03)Can subsidies to domestic producers, de facto, be subsidies to foreign producers? If so, state aid may distort competition to the advantage of the foreign producers. At the same time, governments often oppose subsidies elsewhere, claiming that their industry is hurt. The possibility that governments fight subsidies on these grounds, although the effects are to the contrary, constitutes what is called ... -
The translog neoclassical growth model
(Working paper; Arbeidsnotat, 2004-03)The macroeconomic growth equation based on the translog aggregate production function is derived and compared to the growth equation based on Cobb-Douglas both with and without human capital. The model is estimated directly in structural form, using international panel data. Results are compared to the Cobb-Douglas case and a conventional fixed effect model. -
Government financial transfers to the fish harvesting, processing and aquaculture industries Norway 1990 - 2002
(Working paper; Arbeidsnotat, 2004-03)This report investigates and quantifies Norwegian governmental financial transfers (GFT) to primarily the fish harvesting industry, but also the fish processing and aquaculture industries. Focus is on the period 1990 to 2002. The data sources for this report are mainly public accounts of the Ministry of Fisheries, that channelled the bulk of support measures. We also rely heavily on a set of ... -
Regulation and foreclosure
(Working paper; Arbeidsnotat, 2003-12)The paper considers the optimal regulation of access charges, and the effect such regulation has on incentives to foreclose downstream rival firms. I show that when a vertically integrated firm is able to discriminate against rivals by means of non-price measures, optimal access charges must be set higher than in the case when no discrimination is possible and will always provide a positive ... -
Regulation of a vertically differentiated duopoly
(Working paper; Arbeidsnotat, 2003-12)This paper focuses on the optimal quality regulation of vertically differentiated duopolies in the presence of asymmetric information. In the model presented there are cross-effects on the information rent. Contrary to standard single-agent models, the production levels are distorted in favour of the most efficient firm, whose production level is increased under asymmetric information relative ... -
Should environmental projects be subsidised? An empirical analysis
(Working paper; Arbeidsnotat, 2003-12)Imperfect markets, asymmetric information and transboundary pollution are all characteristics that in most cases lead to inefficient “market” outcomes, and which thus are arguments for (public) intervention in the market. On the other hand, these characteristics also imply strategic behaviour by the economic agents, and then the effects of public intervention may be different from the traditional ... -
Quotas, marine reserves and fishing the line. When does marine reserve creation pay?
(Working paper; Arbeidsnotat, 2003-11)This paper explores the issue of using marine reserves in combination with quotas as fisheries management tools using a patchy environment model as the biological foundation. The rent generated by fishing on the total population, using optimal quotas as a management tool, is compared to the rent from the fishery when managed with quotas and a marine reserve. This is done under different assumptions ...
