When disruptive and downstream innovation become frequent, ontological unpredictability becomes increasingly important for innovation policy and strategy.

متن کاملCooperation in an Unpredictable Environment
A framework for studying the evolution of cooperative behaviour in a random environment, using evolution of finite state strategies, is presented. The interaction between agents is modelled by a repeated game with random observable payoffs. The agents are thus faced with a more complex situation, compared to the Prisoner’s Dilemma that has been widely used for investigating the conditions for c...
