The paper sets up a four-stage enforcement model of fish quotas. The purpose of the paper is to show how the level of enforcement set by the authorities af-fects the way fishermen form coalitions. We show that a high level of control effort yields less cooperation among fishermen, while in the...

This paper examines the social economic value of the Greenland off-shore shrimp fishery. The contribution of the fishery to the economy is examined using a cost-benefit analysis where the objective of the report is to examine the current state of the fishery rather than possible changes, which...

Ecosystem Management requires models that can link the ecosystem level to the operation level. This link can be created by an ecosystem production model. Because the function of the individual fish in the marine ecosystem, seen in trophic context, is closely related to its size, the model groups...

The term 'Fishing Down Marine FoodWebs' describes the gradual transition in landing from marine ecosystems towards organisms lower in the food web. To address this issue and the need to manage the marine ecosystem in a broader perspective, Ecosystem Management is recommended. Ecosystem...

An ecosystem approach means different things to different people. As a result the concept of ecosystem-based fishery management is evolving and it has no universal definition or consistent application. As regards ecosystem modeling, most economic models of fishery ignore the linkages to lower...

The fishing fleet and the component parts of effort and production can be de-scribed and analysed in different ways. As an example, the fishing fleet can be described using a list of different production function specifications. These pro-duction functions will in this paper be estimated using...

Game theory is an analytical tool for modeling strategic interaction between agents. Strategic interaction in fishery is interpreted as the harvest by one agent highly affects other agents' decision. This paper is a commented literature study on the fishery economics and game theory. It tends to...

Within fisheries it is well-known that several market failures exist. However, fisheries economists analyse these market failures separately despite the fact that the market failures arise simultaneously. In this paper several market fail-ures that arise simultaneously are analysed. A resource...

The paper sets up a discrete-time, deterministic, coalition game model among the major agents exploiting the cod stock in Baltic Sea. The characteristic func-tion is constructed and the Shapley value and the nucleolus are used as one-point solution concepts. The paper identifies the problem with...
