We present a model of a multi-species fishery and show that (i) consumer preferences for seafood diversity may trigger a sequential collapse of fish stocks under open-access fishery, (ii) the stronger the preferences are for diversity the higher is the need for coordinated multi-species...

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...

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...

In many spatial resource models it is assumed that the agent is able to determine the harvesting activity over the complete spatial domain. However, agents frequently have only access to a resource at particular locations at which the moving biomass, such as fish or game, may be caught or...

This paper examines how rotation arrangement between two groups of Japanese fishers with different institutional arrangements affects fishing behaviour and economic outcomes in a particular economic environment characterised by price discrimination and product durability. In one group, fishers...

This article develops and implements a Real Options approach to value renewable natural resources in the case of Marine Fisheries. The model includes two sources of uncertainty: the resource biomass and the price of fish, and it can be used by fisheries to optimally adapt their harvesting...

We investigate the relationship between quota enforcement, compliance, and Capital accumulation in ITQ regulated fisheries. Over-extraction and over-capacity represent two of the main fisheries management challenges, and we aim to model and analyze the two jointly. In a stylized resource model,...

In standard models of spatial harvesting, the resource is distributed over the complete domain and the agent is able to control the harvesting activity everywhere all the time. In some cases though, it is more realistic to assume that the resource is located at a single point in space and that...

Nutrient enrichment of marine ecosystems is regarded as a pressing global environmental problem. For certain marine species it may be a mixed blessing, resulting in damaging ecosystem events, but contributing to primary productivity. Consequently, the impact of enrichment on fishery profits may...
