Creator:: Tveterås, Ragnar and Tveterås, Sigbjørn
Abstract:: A food consumption revolution is taking place in Russia. After decades of severe constraints on food consumption options under the communist regime Russian consumers are now adopting new food products - including seafood products - at a high pace. Since Russian consumers have had limited seafood consumption choices before, the...

Creator:: Eggert, Hakan and Tveteras, Ragnar
Abstract:: Several factors contribute to the productivity of nations' fisheries: (1) The biophysical conditions that determine the abundance of fish stocks, (2) government regulation of fisheries, and (3) innovation and adoption of (i.e. investments in) new fishing technologies. This paper analyzes the long-run productivity performance of three Nordic countries Iceland, Norway...

Abstract:: This paper analyses the factors explaining productivity and efficiency differences across salmon aquaculture farms, with an emphasis on agglomeration externalities. We specify a stochastic frontier production model with agglomeration indexes included in both the frontier production function and the technical inefficiency model. The frontier model is estimated on a rich...

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...

Abstract:: Russia is experiencing deep structural changes in many areas. For the seafood industry important developments are large increases in household incomes, development of modern super- and hypermarket distribution channels, and product innovations. In the seafood category consumers are adopting new species and new product forms at a rapid rate. Herring...

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...

Creator:: Roll, Kristin H., Asche, Frank, and Tveterås, Ragnar
Abstract:: In industries that are characterized by frequent innovations and high productivity growth, substantial variation in both produced quantity and input use may occur and lead to increased cost. As both excessive input use and misallocation of inputs are costly for the producer, firm-specific measures of both technical and allocative inefficiency...

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...

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...

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...
