  • Modeling Demand for Fishmeal Using a Heterogeneous Estimor for Panel Data

    Creator:
    Tveterås, Ragnar, Tveterås, Sigbjørn, and Sissener, Elin H.
    Abstract:
    Increased livestock and aquaculture production can put pressure on the fishmeal market, and thus industrial fisheries stocks, since both of these sectors use fishmeal in their feeds. Data indicate that fishmeal supply has reached a production limit due to limited marine resources. Meanwhile there has been an explosive growth in...

  • Aggregation Level and Prediction of Fishing Vessel Behavior and Productivity

    Creator:
    Asche, Frank, Eggert, Hakan, and Tveteras, Ragnar
    Abstract:
    Fishing overcapacity has lead to unsustainable harvesting and rent dissipation in global fisheries. Only government intervention of some kind can lead to a reduction in capacity. If efficiency is the primary objective for the regulator, then the least efficient vessels should be decommissioned. Here we analyze the Swedish fishery using...

  • 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...

  • 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...

  • 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...

  • Global Warming and Fisheries: Thoughts on a Sensible Response

    Creator:
    Arnason, Ragnar
    Abstract:
    Atmospheric measurements show that so-called greenhouse gases have been accumulating in the Earth’s atmosphere for well over a century. There are strong indications that human activity plays a significant role in this process. One consequence of the accumulation of greenhouse gases is thought to be an increase in global temperatures...

  • 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...

  • 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...

  • Fisheries Rents: Theoretical Basis and an Example

    Creator:
    Arnason, Ragnar
    Abstract:
    The concept of natural resource rents is much used in the natural resource and fisheries economics literature. It is therefore somewhat surprising that in this same literature it is difficult to find a clear definition of either natural resource rents or fisheries rents. Possibly, as a result, the concept is...
