The East Atlantic Bluefin Tuna Fisheries: Stock Collapse or Recovery?

A discrete time, multi-gear, and age structured bio-economic model is developed for the East Atlantic bluefin tuna fisheries, a paradigmatic example of the difficulties faced in managing highly migratory fish stocks. The model is used to analyse alternative management strategies for the Regional Fisheries Management Organisation (RFMO) managing this fishery, and to investigate some of the policy implications. For the various scenarios, the optimal stock level varies between 500–800,000 tonnes, which compares with a stock level of 150,000 tonnes in 1995. In other words, there is a very strong case for rebuilding the stock. Moreover, the sustainability of the stock is threatened unless a recovery programme is implemented; indeed, the alternative may be stock collapse. Second, to rebuild the stock, Draconian measures are called for: either outright moratoria over fairly lengthy periods, or possibly a more gradual approach to steady state given by a Total Allowable Catch (TAC) at a low level for an extended period of time. Third, the cost of inefficient gear structure is very high indeed.

SME’s Alliance Dynamics in the Mobile Marketing Industry

This paper presents a case study of the two similar sized, new, technology-based firms acting as alliance partners in the Mobile commerce industry. The analysis describes how the alliance dynamics in our case study relate to seminal research in the field of business alliance formation. Contrary to the established predictions we find that the negative influence on alliance performance described as a consequence of the dissolved routinized alliance pattern by seminal authors is not present. At the same time, the case study shows that internalization of complementary assets does not by necessity result in dissolution of the business alliance as argued from a resource and competence based perspective.
