While peer punishment sometimes motivates increased cooperation, it sometimes reduces cooperation. We use a lab experiment to study why punishment sometimes fails. We begin with a gift exchange game with punishment as it has typically been implemented therein since punishment has often backfired in this game. We modify two features of punishment that could increase its efficacy: punishment’s st...

Software piracy has become a global problem that hinders the development of software industry. Therefore, it is important to understand the underlying mechanisms that drive users’ software piracy behavior. Previous literature on this issue heavily relied on the general deterrence theory (GDT) suggesting that two key punishment perceptions namely punishment severity and punishment certainty dete...

In social dilemmas punishment costs resources, not just from the one who is punished but often also from the punisher and society. Reciprocity on the other side is known to lead to cooperation without the costs of punishment. The questions at hand are whether punishment brings advantages besides its costs, and how its negative side-effects can be reduced to a minimum in an environment populated...

Theoretical and experimental research underscores the role of punishment in the evolution of cooperation between humans. Experiments using the public goods game have repeatedly shown that in cooperative social environments, punishment makes cooperation flourish, and that withholding punishment makes cooperation collapse. In less cooperative social environments, where antisocial punishment has b...

Cooperation, where one individual incurs a cost to help another, is a fundamental building block of the natural world and human society. It has been suggested that costly punishment can promote the evolution of cooperation, with the threat of punishment deterring free-riders. Recent experiments, however, have revealed the existence of 'antisocial' punishment, where non-cooperators punish cooper...

We run several experiments which allow us to compare cooperation under perfect and imperfect information in a centralized and decentralized punishment regime. Under perfect and extremely noisy information, aggregate behavior does not differ between institutions. Under intermediate noise, punishment escalates in the decentralized peer-to-peer punishment regime which badly affects efficiency whil...

Punishing defectors is an important means of stabilizing cooperation. When levels of cooperation and punishment are continuous, individuals must employ suitable social standards for defining defectors and for determining punishment levels. Here we investigate the evolution of a social reaction norm, or psychological response function, for determining the punishment level meted out by individual...

Cognitive control theories predict enhanced conflict adaptation after punishment. However, no such effect was found in previous work. In the present study, we demonstrate in a flanker task how behavioural adjustments following punishment signals are highly dependent on punishment sensitivity (as measured by the Behavioural Inhibition System (BIS) scale): Whereas low punishment-sensitive partici...

There are two types of costly punishment, i.e. peer-punishment and pool-punishment. While peer-punishment applies direct face to face punishment, pool-punishment is based on multi-point, collective interaction among group members. Regarding those two types of costly punishment, peer-punishment is especially considered to have the flaws that it lowers the average payoff of all players as well as...

The evolution of cooperation is one of the great puzzles in evolutionary biology. Punishment has been suggested as one solution to this problem. Here punishment is generally defined as incurring a cost to inflict harm on a wrong-doer. In the presence of punishers, cooperators can gain higher payoffs than non-cooperators. Therefore cooperation may evolve as long as punishment is prevalent in the...
