This paper is concerned with the theory of resilience pricing and sustainability measurement in the presence of risk … for regime shift in a dynamic economy-environment system. Following Holling (1973),we consider resilience as the maximal … under uncertainty, we derive the shadow price of resilience that affects the probabilities of the system to flip in the …

Ecosystem resilience, i.e. an ecosystem’s ability to maintain its basic functions and controls under disturbances, is …, resilience insures risk-averse ecosystem users against potential welfare losses. Using a general and stringent definition of … “insurance” and a simple ecological-economic model, we derive the economic insurance value of ecosystem resilience and study how …

Valuing ecosystem services with microeconomic underpinnings presents challenges because these services typically … demonstrates a method to value a portion of ecosystem services when a commercial fishery is dependent on the quality of estuarine …-prey interactions, this paper quantifies part of the value of improved ecosystem function in the Neuse River Estuary when nutrient …

Recent research in the transmission of the protozoan parasite Trypanosoma cruzi, some strains of which cause Chagas' disease, suggests that consumption of vectors by sylvatic hosts such as raccoons may play a role in maintaining the transmission cycle in the wild. As both hosts and vectors have...

In this paper, we investigate the bioeconomicimpacts of selected rebuilding strategies in amultispecies fishery. Using a stylizedbioeconomic model, we identify the conditionsunder which modifying the species selectivityproperties of the gear would contribute to therebuilding of over-exploited...

Based on economic methodology we model an ecosystem with two species in predator-prey relationship: mice feed on grain … and grain feeds on a resource. With optimizing behavior of individual organisms a short-run ecosystem equilibrium is …-run ecosystem equilibria yields the growth function of the mice population which is thus derived rather than assumed.

Synopsis: The oft-cited analogies between ecological and economic systems are exploited to develop a many-species model of population dynamics. In economies, markets are the fundamental institutions in which the interaction of demands and supplies determine the quantities and prices of goods....

If a foraging adaptation comprises a signal for sensory exploitation of prey, does the behavior and its use develop through learning, like many foraging behaviors or does it depend on nonlearned stereotypical motor actions, like many signals for sensory exploitation? We asked whether the...

Many prey respond to the presence of a predator by retreating into a shell or burrow, or by taking refuge in some other way that guarantees their safety but restricts further information from being obtained about the predator's continued presence. When this occurs, the individual predator and...
