The Fishery as Economic Base in the Newfoundland Economy

Creator:: Roy, Noel, Arnason, Ragnar, and Schrank, William E.
Abstract:: Historically, the fishery has been the mainstay of the Newfoundland economy. Inevitably, its importance declined as economic development proceeded, but was still quite substantial at the time of Confederation with Canada in 1949. Since then, however, the census figures show a precipitous decline in the role of the fishery in...

The Artisanal Hilsa Fishery: economically Efficient Fisheries Policy

Creator:: Mome, Masud Ara and Arnason, Ragnar
Abstract:: The hilsa shad (Tenualosa ilisha) fishery is by far the largest single species fishery in Bangladesh. In this paper, a simple bio-economic year-class based model is developed to describe the fishery and examine its properties. With the help of this model, the optimum sustainable yield of the fishery is calculated...

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...

Rents and Rents Drain in the Icelandic Cod Fishery

Creator:: Arnason, Ragnar
Abstract:: This paper estimates current resource rents being generated in the Icelandic cod fishery and compares them to the maximum sustainable attainable ones. For this purpose a simple aggregative model of the cod fishery is specified and empirically estimated. It is found that in spite of the cod stock being in...

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...

Government Expenditure on Fisheries and Fisheries Management in Iceland

Creator:: Arnason, Ragnar, Hafsteinsdóttir, Palína M., and Ragnarsdottir, Ásgerdur
Abstract:: This paper reports on a study of Icelandic government expenditures on fisheries and fisheries management during the period from 1990 to 1996. This study is a part of a joint Canadian, Icelandic and Norwegian project attempting to estimate consistently government expenditures on fisheries and fisheries management in these three countries...

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...

Global Trends in Capture Fisheries, With an Estimate of Global Losses in Marine Fisheries Resource Rents

Creator:: Willmann, Rolf, Arnason, Ragnar, Franz, Nicole, and Kelleher, Kieran
Abstract:: Trends in key fisheries indicators are presented to provide the context for a profile of the economic health of the world's marine fisheries. Estimates of the economic value of global marine fishery production and costs of production are used as inputs to an economic model to derive a range of...

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...

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...

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...

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...

Discontinuous Sustainable Yield: The Exception or the Rule?

Creator:: Arnason, Ragnar
Abstract:: The sustainable yield function is a favoured tool in fisheries policy making. Normally, this function is drawn as a continuous curve in effort-yield space. This means that sustainable yield (harvest) is gradually reduced to zero as fishing effort increases. This, however, does not have to be the case. The sustainable...

Costs of Fisheries Management: Theoretical and Practical Implications

Creator:: Arnason, Ragnar
Abstract:: This paper considers the costs of fisheries management. It starts by reviewing the costs of fisheries management in Iceland, Newfoundland and Norway. The outcome of this study, as well as information from other countries, indicates that fisheries management costs are generally quite substantial relative to the value of landed catch....

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...

Comments on M.L. Weitzman: Landing Fees vs. Harvest Quotas with Uncertain Fish Stocks

Creator:: Arnason, Ragnar
Abstract:: Weitzman's paper is useful because it provides the fisheries economics profession with a reason to re-examine certain elements of the currently accepted fisheries management theory. As a result, this contribution may lead to a more solid theoretical foundation for fisheries management. This, of course, is the way any science is...

Arctic Char Fish Farming in Iceland: Is it a Success?

Creator:: Heimisson, Asgeir Fridrik, Arnason, Ragnar, and Olafsdottir, Gudrun
Abstract:: Fish farming has grown very rabidly during the past few decades. One component of this expansion is the introduction of new species, previously unknown to most consumers, to world markets. Arctic char, a cold water salmonid, is one of these species. In 1987, the total commercial supply only amounted to...
