The debate in commercial fishery management has evolved from whether well-defined rights are necessary for sustainability to measuring the impacts of different rights-based system designs. Most assessments are on developed world fisheries. Using a unique collection of datasets, we develop...

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...

In January 2009 a new management regime of individual vessel quotas (IVQs) was put in force in the world's largest fishery, the Peruvian anchovy fishery. Until 2009, the fishery was managed by a regulated open access system with clear symptoms of the race for fish. We argue that the new regime...

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...

We analyze a policy experiment in an Alaskan commercial fishery that assigned a portion of an overall catch quota to a voluntary cooperative, with the remainder exploited competitively by those choosing to fish independently. Unlike the individual quota system advocated by many economists, the...

Lake Victoria, globally the second-largest freshwater Lake by surface area, houses an artisanal Nile Perch Fishery that directly involves around 200K people. While the 10 whole Lake surface is potentially available to fishing activities, the fishing vessels' operational and technical...

Fisheries management involves many stakeholders with different opinions about how the fishery should be optimally managed. This paper presents a multi-objective bio-economic model, which is able to incorporate the preferences of managers and other stakeholders. The model is a weighted goal...

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...

In this paper, we consider a market where potential firms, which are allowed to be asymmetric, can freely enter and exit, and the total output would be socially excessive without any regulation. The effects of two alternative regulatory policies in the market: the individually transferable quota...

Many biological and economic processes in fishery happen seasonally. Most of the extant literature tends to neglect this fact. This work is an initial attempt to treat seasonality in a systematic and proper way. We apply a periodic Bellman approach to obtain the optimal feedback policy of each...
