We develop a theoretical framework to assess sheries management strategies from a sustainability perspective, when the bioeconomic dynamics are marked by uncertainty. Using stochastic viability, management strategies are ranked according to their probability to satisfy economic and ecological...

Two of the challenges of thinking sustainability are how to deal with potentially conicting issues and how to ensure intergenerational equity. In practice, policymakers define sustainability objectives by setting thresholds that act as constraints on indicators. When defining a specific...

This paper examines how the viability approach can be used to define sustainability goals. In an economic model with a non renewable natural resource, we define minimal rights to be guaranteed for all generations. These rights can include a minimal consumption (economic goal) and the...

Economic analysis addresses risk and long-term issues with discounted expected utility, focusing on optimality. Viability theory is based on sustainability constraints to be satisfied over time, focusing on feasibility. We make a bridge between these two approaches by showing that viability is...
