This article explores the influence of competitive conditions on the evolutionary fitness of different risk preferences. As a practical example, the professional competition between fund managers is considered. To explore how different settings of competition parameters, the exclusion rate and...

The paper analyses the properties and outcomes of competitive dynamics in industries characterized by heterogeneous firms and continuing stochastic entry. A formal analytical apparatus is developed, able to derive some generic properties of the underlying competition process combining persistent...
