We analyze the effect of environmental uncertainties on optimal fishery management in a bio-economic fishery model. Unlike most of the literature on resource economics, but in line with ecological models, we allow the different biological processes of survival and recruitment to be affected...

The objectives pursued by governments managing fisheries may include maximizing profits, minimizing the impact on the marine ecosystem, or securing employment, which all require adjusting the composition of the fishing fleet. We develop a management plan that can be adapted to those objectives...

In most coastal developing countries, the artisanal fisheries sector is managed as a common pool resource. As a result, such fisheries are overcapitalized and overfished. In Ghana, in addition to anthropogenic factors, there is evidence of rising coastal temperature and its variance, which could...

William Forster Lloyd's 1833 sketch about poor cattle on the commons and the well-fed animals on the adjacent enclosures published in his "Two lectures on the checks to population" has hitherto been assessed as one starting point of the economics of renewable resources. In the 20th century the...

Understanding the effect of introducing property rights to natural resources is central in economics, but empirical analysis is frustrated by the complexity of socioecological systems. We construct a detailed bio-economic model of the Norwegian coastal cod fishery, which was closed after 1989,...

Marine Protected Areas are considered as a hedging tool against some of the uncertainties that trouble many fisheries today. Such tools are always connected with a cost; a premium. An optimal harvest rule is combined with a protected area to manage a fishery. The model ignores uncertainty, and...

In this paper the management of straddling fish stocks is approached through a coalition game in partition function form. A two-stage game is applied, assuming ex ante symmetric players and the classical Gordon-Schaefer bioeconomic model. It is shown that the game is characterized by positive...

Artisanal fishing communities include some of the "poorest of the poor". In the past 40 years, strategies that have targeted the harvesting sector of such communities have often failed to address their chronic problems of poverty. Using data from gill net fishers in Malaysia, the paper presents...

We consider a robust control model for a spatially distributed commercial fishery under uncertainty, and in particular a tracking problem, i.e. the problem of robust stabilization of a chosen deterministic benchmark state in the presence of model uncertainty. The problem is expressed in the form...

There are several examples of pelagic fisheries that have experienced fishing collapse when facing downward abundance cycles. Improving understanding about pelagic catch's stock dependence can help avoid new cases of fishing collapse. This paper analyses the possible endogeneity of the fish...
