Spatial-dynamic processes in renewable resource economics pose difficult conceptual, analytical, empirical, and institutional challenges that are distinct from either spatial or dynamic problems. We describe the challenges and conceptual approaches using both continuous and discrete depictions...

Marine ecologists warn that humans are "fishing down marine food webs." To explore the economic implications of this phenomenon, this paper applies portfolio theory to aggregate fisheries data. It poses two definitions of a sustainable mean-variance catch frontier. It computes a mean-variance...

Marine scientists and policymakers are encouraging ecosystem-based fishery management (EBFM), but there is limited guidance on how to operationalize the concept. We adapt financial portfolio theory as a method for EBFM that accounts for species interdependencies, uncertainty, and sustainability...
