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