When two or more agents compete for a bonus and the agents' productivity in each of several possible occurrences depends stochastically on (constant) effort, the number of times that are checked to assign the bonus affects the level of uncertainty in the selection process. Uncertainty, in turn,...

The paper presents a set of games of competition between two or three players in which reward is jointly determined by a stochastic biased mechanism and players’ choices. More specifically, a resource can be found with unequal probabilities in one of two locations. The first agent is...

Predating predators requires at least three specimen to which we refer as players 1, 2, and 3. Player 1 has simply to guess nature when trying to find food. Player 2 is hunting player 1 in the hope that 1 is well-fed but must also avoid being hunted by player 3. One major motivation is to test...

A situation in which the regularity in nature can be utilized while competition is to be avoided is modelled by the Parasite game. In this game regular behaviour could enhance guessing nature but strategic randomization is required to avoid being outguessed. In an experiment, 60 pairs of...

Whether behavior converges toward rational play or fair play in repeated ultimatum games, depends on which player yields first. If responders conceded first by accepting low offers, proposers, would not need to learn to offer more. Play would thus converge toward unequal sharing. If proposers,...

The phenomenon of predating predators requires at least three specimens to whom we refer as players 1, 2, and 3. Player 1 has simply to guess nature when trying to find food. Player 2 is hunting player 1 in the hope that 1 is well fed but must also avoid being hunted by player 3. One major...
