  • Stock and (possibly) path dependent technologies

    Creator:
    Arnason, Ragnar and Willmann, Rolf
    Abstract:
    According to conventional economic wisdom the economically more efficient technology will always outcompete the less efficient. This hypothesis has usually been taken to hold for the exploitation of common pool renewable natural resources such as fish stocks. This paper claims that, while this is not necessarily false, it may be...

  • 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...

  • 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...

  • 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: Basic Theory

    Creator:
    Arnason, Ragnar
    Abstract:
    If fisheries management is supposed to affect behaviour, it has to be enforced. Fisheries enforcement has generally been found to be quite costly compared to the attainable rents from the fishery. This has a number of important implications. First, obviously, it is economically important to operate the enforcement activity at...

  • 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...

  • Community Fishing Rights: Some Basic Principles

    Creator:
    Arnason, Ragnar
    Abstract:
    It is now widely recognized that property rights based fisheries management regimes are well suited for generating efficiency in fisheries. Apart from access licences, which are very low quality property rights, individual quotas (IQs) and individual transferable quotas (ITQs) are the most widely applicable and, indeed, the most commonly applied...
