The Evolution of Coordination under Inertia∗
This paper models the phenomenon of inertia driven by individual strategy switching costs in a stochastic evolutionary context. Kandori, Mailath, and Rob’s (1993) model of a finite population of agents repeatedly playing a 2 x 2 symmetric coordination game is extended to allow for such inertia. Taking noise to the limit, a number of new shortto medium-run equilibria emerge, centred around the m...
متن کاملThe Evolution of Conflict under Inertia∗
In Norman (2003a), the introduction of individual strategy switching costs, and thus inertia, into stochastic evolutionary coordination games was found inter alia to strengthen the mixed-strategy equilibrium as a shortto medium-run equilibrium. This paper considers the impact of such switching costs on the conflict scenario of HawkDove games. The “attractive” mixed-strategy equilibrium of HawkD...
متن کاملGenomic changes under rapid evolution: selection for parasitoid resistance.
In this study, we characterize changes in the genome during a swift evolutionary adaptation, by combining experimental selection with high-throughput sequencing. We imposed strong experimental selection on an ecologically relevant trait, parasitoid resistance in Drosophila melanogaster against Asobara tabida. Replicated selection lines rapidly evolved towards enhanced immunity. Larval survival ...
متن کاملStructural Inertia and Organizational Change Revisited III: The Evolution of Organizational Inertia*
Building on a formal theory of the structural aspects of organizational change initiated in Hannan, Pólos, and Carroll (2002a, 2002b), this paper focuses on structural inertia. We define inertia as a persistent organizational resistance to changing architectural features. We examine the evolutionary consequences of architectural inertia. The main theorem holds that selection favors architectura...
متن کاملEvolution under changing climates: climatic niche stasis despite rapid evolution in a non-native plant.
A topic of great current interest is the capacity of populations to adapt genetically to rapidly changing climates, for example by evolving the timing of life-history events, but this is challenging to address experimentally. I use a plant invasion as a model system to tackle this question by combining molecular markers, a common garden experiment and climatic niche modelling. This approach rev...
