In commercial fisheries, stock collapse is an intrinsic problem caused by overexploitation or due to pure stochasticity. To analyze the risk of stock collapse, we apply a relatively simple Monte Carlo approach which can capture complex stock dynamics. We use an economic model with downward...

Renewable resources are affected by both environmental variability, which makes the year-to-year stock growth uncertain, and the risk of irreversible events (e.g., a stock collapse). Little is known about how a renewable resource harvester would optimally respond to the combined effects of both...

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...

We study the impact of uncertainty on the strategies and dynamics of symmetric non-cooperative games among players who exploit a non-excludable resource that reproduces under uncertainty. We focus on a particular class of games that deliver a Nash equilibrium in linear-symmetric strategies of...

Climate change is likely to trigger abrupt and potentially persistent changes in the structure and function of marine ecosystems. Such ‘regime shifts' threaten the livelihoods of millions of people reliant on small-scale fisheries. Yet, it is largely unknown how resource users cope with regime...

Climate change is projected to severely damage the global economy. Adaptation in response to a changing climate will affect how much damage ultimately occurs. This paper introduces a method for estimating forward-looking adaptation based on differences in responses to forecasts and realizations...

Cooperation is thought to be a necessary condition to solve collective dilemmas such as climate change or the sustainable use of common-pool resources. Yet, it is poorly understood how situations pervaded by thresholds shape the behaviour of people facing collective dilemmas. Here we provide...

Salmon farming companies are increasingly gaining attention from investors and portfolio managers. The last decade has seen a substantial growth in the securitization of salmon farming assets and prices. A growing literature demonstrates that industry-specific fundamental, as well as market-wide...

Individual transferable quotas (ITQs) in multispecies fisheries create incentives for fishermen to avoid bycatch of species for which quota is scarce. However, when bycatch is highly uncertain, individual quota demand and prices may be volatile creating substantial financial risk for fishermen....

Spatial management of a fishery under parameter uncertainty is analyzed. The habitat is divided into two areas, and the effort level in the two areas may be different. The migration of biomass between the areas follows a diffusion process; two different specifications are considered. The model...
