• Are within-season rents maximised in an open-access fishery? 

      Kennedy, John; Hannesson, Rögnvaldur (Working paper, Working paper, 2003-08)
      It is often assumed that zero rents are generated in an open-access fishery. There are many justifications for this, such as the existence of intraseasonal and interseasonal stock externalities, and entry and exit of vessels ...
    • Buy-back programs for fishing vessels in Norway 

      Hannesson, Rögnvaldur (Working paper, Working paper, 2004-03)
      In Norway, buy-back programs have been in force since 1979. Grants have been given to scrap fishing vessels or to sell them out of the country. These programs have been most successful for the purse seine fleet. Since the ...
    • Cheating about the cod 

      Hannesson, Rögnvaldur (Working paper, Working paper, 2006-12)
      The Northeast Arctic cod is managed by a total quota shared evenly between Norway and Russia. It appears that Russia has been overfishing its quota by substantial amounts for a number of years, due to insufficient monitoring ...

      Lorentzen, Torbjørn; Hannesson, Rögnvaldur (Working paper, Working paper, 2005-04)
      The background for the paper is the expected climate change and its effect on the Norwegian mackerel fishing industry. Global warming is expected to affect the ecosystem in the Northeast Atlantic. Considerable uncertainty ...
    • The collapse of the Norwegian herring fisheries in the late 1950s and 60s : crisis, adaptation, and recovery 

      Lorentzen, Torbjørn; Hannesson, Rögnvaldur (Working paper, Working paper, 2004-03)
      This paper deals with the economic effects of the collapse of the Atlanto-Scandian and the North Sea herring stocks on the Norwegian fisheries. In the late 1950s the Norwegian winter herring fishery failed, and in the 1960s ...
    • Cooperative equilibria in fisheries : how many players? 

      Hannesson, Rögnvaldur (Working paper, Working paper, 2007-04)
      This paper investigates conditions under which fisheries agreements between states are self-enforcing. Cooperative solutions can be self-enforcing if parties to the agreement punish those who depart from the cooperative ...
    • The development of productivity in the Norwegian fisheries 

      Hannesson, Rögnvaldur (Working paper, Working paper, 2005-04)
      The development of total factor productivity in the Norwegian fisheries 1961-2002 is estimated, using data on catches at constant fish prices, capital stock, labor input, and fish stocks. Data on fish stocks have been ...
    • Does scale efficiency tell us anything about optimal scale? 

      Hannesson, Rögnvaldur (Working paper, Working paper, 2005-04)
      In DEA, scale efficiency is routinely calculated. This measure may, however, tell us very little about whether a production unit is over- or undersized. An empirical case is used to illustrate that, under some circumstances, ...
    • Geographical distribution of fish catches and temperature variations in the Northeast Atlantic since 1945 

      Hannesson, Rögnvaldur (Working paper, Working paper, 2006-01)
      Warming of the northeast Atlantic is expected to affect the location and productivity of fish stocks. It is examined whether variations in catches of cod, herring, mackerel, anchovy and sardines in the ICES statistical ...
    • Global warming and fish migrations 

      Hannesson, Rögnvaldur (Working paper, Working paper, 2005-01)
      Ocean temperatures are expected to rise over the next decades. This is likely to affect the distribution of fish stocks between the exclusive economic zones (EEZs) of different countries. Such changes are likely to be ...
    • Implicit cooperation? The northeast atlantic mackerel fishery 

      Hannesson, Rögnvaldur (Working paper;14/13, Working paper, 2013-04)
      This paper presents a quarterly, game-theoretic model of the Northeast Atlantic mackerel to study the fishing strategies of five players, the EU, Norway, the Faeroe Islands, Iceland, and the international fishery on the ...
    • Incentive compatibility of fish-sharing agreements 

      Hannesson, Rögnvaldur (Working paper, Working paper, 2004-04)
      This paper discusses the incentive compatibility of fish-sharing agreements based on zonal attachment of fish stocks. It is shown that the minor partner in a fish-sharing agreement may not have an incentive to cooperate ...

      Hannesson, Rögnvaldur (Working paper, Working paper, 2004-11)
      Shared fish stocks are such as migrate across borders between different countries’ exclusive economic zones. This paper discusses the incentive compatibility of fish-sharing agreements based on the zonal attachment of such ...
