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 ...

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 ...

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 ...

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 ...

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 ...

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, ...

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 ...

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 ...

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 ...

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 ...
