The paper shows that being able to forecast another player's actual cooperation better than pure chance can change players' strategic incentives in a one-shot simultaneous PD-situation. In particular, it is shown that if both players have such ability (to forecast each others' actual choices...

Markov perfection has become the usual solution concept to determine the non-cooperative equilibrium in a dynamic game. However, Markov perfection is a stronger solution concept than subgame perfection: Markov perfection rules out any cooperation in a repeated prisoners' dilemma game because the...

We analyse interethnic cooperation in an infinitely repeated prisoner's dilemma when members of one group are unable to target punishment towards individual defectors from the other group. We first show that indiscriminate outgroup punishment may sustain cooperation in this setting. Our main...

In der traditionellen Spieltheorie sind Strategien äquivalent mit Handlungen und gemischte Strategien die einzige Erweiterung dazu. Als eine neue Erweiterung werden Strategien als Pläne interpretiert. Obgleich die meisten Pläne nicht sehr interessant sind (wie eine bestimmte Handlung zu tun),...

We analyse interethnic cooperation in an infinitely repeated prisoner’s dilemma when members of one group are unable to target punishment towards individual defectors from the other group. We first show that indiscriminate outgroup punishment may sustain cooperation in this setting. Our main...

Such problems as inner-city traffic congestion and pollution are often asserted to be examples of the n-person Prisoners` Dilemma Game (PD), but there is a dearth of empirical research that tests this assertion. 551 car owners in Oxford responded to three pairs of alternatives designed as...

While the so-called ‘refugee crisis’ in Europe led to the de facto suspension of the Dublin Regulation in 2015/2016, researchers and practitioners are well aware that the crisis only highlighted existing shortcomings of the system governing the responsibility-allocation for asylum-seekers in...

We have studied the impact of time-dependent learning capacities of players in the framework of spatial prisoner's dilemma game. In our model, this capacity of players may decrease or increase in time after strategy adoption according to a step-like function. We investigated both possibilities...

Strategy changes are an essential part of evolutionary games. Here we introduce a simple rule that, depending on the value of a single parameter w, influences the selection of players that are considered as potential sources of the new strategy. For positive w players with high payoffs will be...

Standard game theory turns a blind eye toward social interaction between the players in a game. Hence, a given game offers the same set of equilibria regardless of the identities of the players and the specifics of the social context. The predictive value of game theory is severely limited as a...
