• The Backward-Bending Supply Curve in Fisheries-Revisited 

      Pham, Thanh Thuy; Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      This study discusses and estimates the backward-bending supply curve, using data for three years over a six-year time span from the inshore purse seine fishery in Khanh Hoa province, Vietnam. Four different models are developed for estimation based on fisheries data, in the absence of stock survey data. The estimated maximum sustainable yield for the anchovy in south-central Vietnam ranges from ...

    • Global aquaculture growth and institutional quality 

      Nadarajah, Suthamathy; Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10)
      The global aquaculture sector has grown continuously over the past 40 years, though unevenly among countries. Differences in factors such as inputs, climate, management, technology, markets, social environment, and institutions might be reasons for the disparities in growth. This study focuses on institutions, by analyzing the relationship between annual growth in the production of the major aquaculture ...
    • Institutional quality and catch performance of fishing nations 

      Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      The relationship between annual growth in the catches of fishing nations and the quality of the institutions of those nations is analyzed. Catch volumes are used as a proxy for development, since economic performance indicators based on a common set of definitions do not exist. 49 major fishing nations were selected for this study, including 22 OECD countries and several developing countries. Three ...
    • Marine protected areas in a welfare-based perspective 

      Reithe, Siv; Armstrong, Claire W.; Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-05-04)
      Assuming a broad set of fisheries management goals, this paper analyzes the implementation of a marine protected area (MPA) together with open access outside, applying a bioeconomic model that ensures unchanged growth post-MPA. Taking into account that conservation and restoration, food security, employment and social surplus are amongst the objectives that many managers include in fisheries management, ...
    • Middlemen: good for resources and fishermen? 

      Pham, Thi Thanh Thuy; Flaaten, Ola; Skonhoft, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-16)
      This paper studies the role of middlemen in open-access fisheries and how the organization of the supply chains affects resource exploitation and the level and distribution of economic rent. Imperfect competition among middlemen can help ensure that fish stocks are not depleted, which is typically the case in open-access fisheries with competitive markets. Middlemen with market power can also induce ...
    • Overskudd og ressursrente -mer for Nord-Norge? 

      Flaaten, Ola; Heen, Eirik Eriksen; Heen, Knut (Chapter; Bokkapittel, 2023)
      Artikkelen beskriver utviklingen i fiskeri- og havbruksnæringen i Nord-Norge, med spesiell vekt på Finnmark og Nord-Troms. Norsk økonomisk sone har her det biologiske grunnlaget for landets viktigste fiskerier. Fiskeriene har gått fra å være en åpen næring til en lukket og eksklusiv «klubb». Konsekvensene for næringen i Nord-Norge har vært sentralisering i færre enheter og svekking av mange lokalsamfunn. ...
    • Profit and Resource Rent in Fisheries 

      Flaaten, Ola; Matthiasson, Thorolfur (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-19)
      The difference between the concepts of profit and rent are discussed theoretically and by using aggregated data from the Icelandic and Norwegian fish harvesting industries. The former is a basic indicator for gauging the business performance of firms and industries, and the latter is important for the evaluation of the economic welfare contribution of resources and industries. The importance of ...

    • Rebuilding the Northeast Arctic Cod Fisheries - Economic and Social Issues 

      Armstrong, Claire W.; Eide, Arne; Flaaten, Ola; Heen, Knut; Kaspersen, Inga Wigdahl (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      The Northeast Arctic cod (NEA cod) fisheries in Norway are now one of the richest cod fisheries in the world. In the past the fishery has experienced several stock declines and low economic returns. In this paper we review management approaches applied over 20 years to address one of the most severe crises in the fishery. Emphasis is on management strategies and the measures carried out to ensure ...
    • Resource rent in aquaculture 

      Flaaten, Ola; Pham, Thi Thanh Thuy (Chapter; Bokkapittel, 2019)
      Resource rent in aquaculture (RRA) is any payment to a farm and site owner, on land or sea, in excess of the costs needed to bring that farm into production. For analytic and policy purposes it may be useful to distinguish among different types of RRA. Three types will be discussed: rent associated with the classical economists Ricardo (1821) and Faustmann (1849), as well as oligopoly rent from ...
    • The rise and decline of fishing industry support – with a translation from Norwegian of Bjørn S. Brochmann's 1981 article ‘long-term effects of government support to the fisheries’ 

      Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-21)
      Input and output measures, including the use of (Pigou) taxes, have been recommended to bridge the gap between average and marginal revenues in fisheries. Several countries have improved management, but few have followed the fiscal recommendations. On the contrary, subsidies that can expand capacity and effort have been and still are used. For decades, international organizations such as the WTO, ...
    • Stubborn fuel tax concessions: The case of fisheries in Norway 

      Isaksen, John Roald; Hermansen, Øystein; Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-11-22)
      In the context of the abolition of traditional subsidies, this paper discusses the persistence of the major remaining subsidy scheme in Norwegian fisheries: exemption from fuel taxes. This reimbursement scheme stems from the late1980s, and has persisted since then under different governments. This paper gives the background to this support against theoretical predictions of the subsidy's effects on ...
    • Subsidies—Help or Hurt? A Study from Vietnamese Fisheries 

      Pham, Thi Thanh Thuy; Flaaten, Ola; Nguyen, Trong Luong; Vu, Ke Nghiep (Journal article; Tidsskriftartikkel, 2021)
      Subsidies are part of the set of management tools that governments apply to modernize their fishing fleets and enable them to engage in offshore and international fisheries. Research has shown that subsidies often lead to overcapacity and overfishing, resulting in the depletion of fish stocks. A few studies, however, have found some positive effects for particular subsidies. In this paper, we ...
    • Økosystemforvaltning - Hvorfor økonomisk analyse er viktig 

      Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      <p>I et økosystem vil noen arter være byttedyr, andre predatorer og mange begge deler, skiftende gjennom sitt livsløp. Så også i de marine økosystem der norske fiskere årlig fisker mellom 2 og 3 millioner tonn, noe som gjør at Norge er blant de 10 største fiskerinasjoner i verden. De fleste fiskebestander av stor kommersiell verdi har en utbredelse som innebærer at årlige totalkvoter fastsettes og ...
