Theoretical papers find that taxes are preferred over individual transferable quotas (ITQs) when fisheries regulators are uncertain about either biological growth or the extent of non-compliance with regulations. However, the size of the welfare gain from switching to taxes has not previously...

We study optimal fishery management in an age-structured, bio-economic model where two age classes can be harvested independently. We show that the optimal amount of catch differs with age classes, and we derive conditions under which it is optimal to harvest only one age class. Our main policy...

The problem of the commons is more important to our lives and thus more central to economics than a century ago when Katharine Coman led off the first issue of the American Economic Review. As the U.S. and other economies have grown, the carrying-capacity of the planet - in regard to natural...

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...

This paper uses a non-market valuation study to elicit consumers' preferences for a marine restoration programme in the Black Sea aiming to reduce the level of public health risk from bathing and improve water quality and the overall level of marine biodiversity. In this context, we administer a...

The Pacific Island nations heavily rely on the tuna fishery for government revenue and economic growth. Since the conversion of some nations to the Vessel Days Scheme (VDS) from the fishing Quota system, the region's domestic catch has significantly increased. VDS has stimulated economic return...

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...

User rights in fisheries refer to the rights of fishers to harvest from fish resources. In terms of security, exclusivity, duration, and transferability these rights can be strong or weak. In recent years there has been a substantial movement toward stronger user rights in many fisheries around...

In previous research it was concluded that a transition to SURFs (strong user rights in fisheries) has several economic, environmental, and social impacts. In this paper, the problem of assessing the values of these impacts is considered. First, this kind of an assessment is considered in...

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,...
