  • On the Appropriate Rate of Discount

    Creator:
    Arnason, Ragnar
    Abstract:
    Discount rates, it is well-known, play an important role in the determining optimal extraction paths for natural resources. In fisheries analysis, as well as other natural resource use, constant discount rates are customarily assumed. In practical applications, the constant discount rate is often taken to be the social rate of...

  • Fisheries Management Services in Iceland: Costs and Arrangements

    Creator:
    Arnason, Ragnar
    Abstract:
    To run the ITQ system as well as other components of the fisheries management system, the Icelandic government conducts a number of activities which may be regarded as fisheries management services. The most important of these are performed by (i) the Fisheries Directorate which maintains the quota registry and enforces...

  • Economics of the Global Marine Fishery: Changes between 2004 and 2012

    Creator:
    Arnason, Ragnar
    Abstract:
    In 2009 the World Bank published a study of the economic performance of the global marine fishery pertaining to the base year 2004. The key finding of this study was that the global fishery in 2004 was economically and biologically highly inefficient. More precisely, the difference between attainable and actual...

  • Economically Sensible Caps on ITQ-Holdings

    Creator:
    Arnason, Ragnar
    Abstract:
    Many ITQ fisheries are subject to an upper limit or cap on ITQ-holdings by individual companies. The economic rationale for these caps seems to be to reduce the opportunities for monopolistic behaviour by the companies. A possible social cost of the caps is that limiting company size in fisheries, especially...

  • Optimal Dynamic Enforcement of A Fishery

    Creator:
    Arnason, Ragnar
    Abstract:
    It has been established that the path of a fishery over time, i.e. stocks, fleets, effort and profits, depends inter alia on the enforcement of the fisheries management rules in place. It has further been established that optimal enforcement of fisheries management rules depends inter alia on the shadow value...

  • Profits, Rents and Resource Rents

    Creator:
    Arnason, Ragnar
    Abstract:
    The concept of rents has a venerable history in economic theory. In his fundamental work on the Wealth of Nations, Adam Smith defined the concept making it clear that rents were distinct from profits. Ricardo, building on the foundation laid by Adam Smith, similarly distinguished between profits and rents in...

  • ITQ Prices: What do they Reveal?

    Creator:
    Arnason, Ragnar
    Abstract:
    ITQ systems generate ITQ prices. For any given ITQ-managed species there are typically two prices. One is for the annual (or seasonal) quota, the other is for the longer lasting ITQ-share. In well-functioning ITQ markets, these prices reveal important information about the fishery. In the single species framework, prices of...

  • Fisheries Enforcement When Avoidance Is Possible

    Creator:
    Arnason, Ragnar
    Abstract:
    When fishers can avoid detection and/or sanctions for violating fisheries management rules, the fisheries enforcement problem becomes substantially more complicated. A number of issues immediately pop up. First, the effectiveness of enforcement effort is reduced. This, ceteris paribus, reduces the optimal enforcement effort. Second, the impact on the fishery of...

  • On the Economic Distortion of Pure Resource Rent Taxation

    Creator:
    Arnason, Ragnar
    Abstract:
    It is often taken for granted that taxation of rents is economically nondistortive. In certain areas of natural resource use, e.g. oil extraction and fisheries, this nondistortion principle has been used to justify taxation of what is regarded as resource rents. This paper challenges the view that such taxation is...
