Rebuilding Strategies for Multispecies Fisheries: A Stylized Bioeconomic Model

Agar, J.J.; Sutinen, J.G. - In: Environmental & Resource Economics 28 (2004) 1, pp. 1-29

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...

Optimal pest control in agriculture

Christiaans, Thomas; Eichner, Thomas; Pethig, Rüdiger - Fakultät Wirtschaftswissenschaften, … - 2005

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. In each period …

Ecological Transfers in Non-Human Communities Parallel Economic Markets in a General Equilibrium Ecosystem Model

Tschirhart, John - In: Journal of Bioeconomics 5 (2003) 2, pp. 193-214

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....

Innate plasticity of a predatory behavior: nonlearned context dependence of avian flush-displays

Jab, Piotr G.; lstrok; o; nacute; ski; Lee, Sang Don; … - In: Behavioral Ecology 17 (2006) 6, pp. 925-932

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...

The waiting game: a "battle of waits" between predator and prey

Hugie, Don M. - In: Behavioral Ecology 14 (2003) 6, pp. 807-817

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...

Two-Population Social Cycle Theories

Callahan, Gene; Hoffmann, Andreas - Volkswirtschaftliche Fakultät, … - 2015

Discerning family resemblances in the world of theories can be useful for several reasons. For one thing, noticing that two theories share the traits of a family of theories may help us to understand each of them better. Secondly, noticing the family resemblances may help us to model them more...

Venture capital investment: the role of predator-prey dynamics with learning by doing

Brander, James; Bettignies, Jean-Etienne De - In: Economics of Innovation and New Technology 18 (2009) 1, pp. 1-19

This paper suggests that endogenous dynamics of the 'predator-prey' type can provide a contributing explanation for both high-venture capital concentration by industry and 'boom and bust' industry-level investment dynamics. We propose a model based on the idea that venture capitalists favor...
