Whether or not there are gender differences in altruistic behaviour in Dictator Game experiments has attracted considerable attention in recent years. Earlier studies found women to be more altruistic than men. However, this conclusion has been challenged by more recent accounts, which have...

We examine whether spillovers of pro-social behavior depend on how behavioral changes are induced. We conduct a large experiment using economic games, with a Dictator Game (DG) followed by either an identical game or a Prisoner’s Dilemma (PD). We influence initial behavior through widely used...

Groups make decisions on both the production and the distribution of resources. These decisions typically involve a tension between increasing the total level of group resources (i.e. social efficiency) and distributing these resources among group members (i.e. individuals' relative shares)....

The semigroup game is a two-person zero-sum game defined on a semigroup <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$${(S,\cdot)}$$</EquationSource> </InlineEquation> as follows: Players 1 and 2 choose elements <InlineEquation ID="IEq2"> <EquationSource Format="TEX">$${x \in S}$$</EquationSource> </InlineEquation> and <InlineEquation ID="IEq3"> <EquationSource Format="TEX">$${y \in S}$$</EquationSource> </InlineEquation>, respectively, and player 1 receives a payoff f (x y) defined by a function f : S → [−1, 1]. If the semigroup is amenable...</equationsource></inlineequation></equationsource></inlineequation></equationsource></inlineequation>

Although mixed extensions of finite games always admit equilibria, this is not the case for countable games, the best-known example being Waldʼs pick-the-larger-integer game. Several authors have provided conditions for the existence of equilibria in infinite games. These conditions are...

The implausibility of the extreme rationality assumptions of Nash equilibrium has been attested by numerous experimental studies with human players. In particular, the fundamental social dilemmas such as the Traveler's dilemma, the Prisoner's dilemma, and the Public Goods game demonstrate high...

Understanding whether preferences are sensitive to the frame has been a major topic of debate in the last decades. For example, several works have explored whether the dictator game in the give frame gives rise to a different rate of pro-sociality than the same game in the take frame, leading to...

In the Ultimatum Game (UG) one player, named “proposer”, has to decide how to allocate a certain amount of money between herself and a “responder”. If the offer is greater than or equal to the responder’s minimum acceptable offer (MAO), then the money is split as proposed, otherwise,...
