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 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...
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...
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...
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...
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...
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...
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...
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...
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...
