The rise and fall of the Great Fish Pact under endogenous risk of stock collapse
Walker, Adam N.; Weikard, Hans-Peter; Richter, Andries - 2015
Risk of stock collapse is a genuine motivation for cooperative fisheries management. We analyse the effect of an endogenously determined risk of stock collapse on the incentives to cooperate in a Great Fish War model. We establish that equilibrium harvest strategies are non-linear in stock and...

Catastrophes and expected marginal utility : how the value of the last fish in a lake is infinity and why we shouldn't care (much)
Nævdal, Eric - 2015 - This version March 2015
Catastrophic risk is currently a hotly debated topic. This paper contributes to this debate by showing two results. First it shown that the value function in dynamic optimization can have an infinite derivative at some point even if the model specification has functional forms that are finite...

Optimum fisheries management under climate variability : evidence from artisanal marine fishing in Ghana
Akpalu, Wisdom; Dasmani, Isaac; Normanyo, Ametefee K. - 2014
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...

Pricing on the fish market : does size matter?
Sjöberg, Eric - 2014
The importance of fish size for price per kilo is studied using an inverse demand approach. Prices per kilo in different size categories of the same species differ significantly. This means that the average price for a species may change due to e.g., high-grading, growth overfishing or a...
