This paper studies the evolution and co-evolution of both characteristics of reciprocity - the willingness to reward friendly behavior and the willingness to punish hostile behavior. Firstly, both preferences for rewarding and preferences for punishing can survive in evolution provided...

The principal challenge in designing intelligent agents (IAs) is to make their interactions with humans feel natural and acceptable. This review focuses on the employed social cues in intelligent agents that can enhance the quality of Human-IA interactions. We conducted a literature review and...

We examine a game of harvesting a renewable common resource and investigate the ramifications of competition. We formulate the problem as an impulse control game between two competing harvesters and devise a new formulation of closed-loop impulse control strategies. In the case of non-zero setup...

Individual contributions to public goods can be framed in absolute or relative metrics. We examine how the framing salience affects the contribution behavior when group members are heterogeneously endowed, based on a reference-dependent theory with salience weights allocated to the absolute or...

Myopic individuals belonging to an infinite population repeatedly and independently have to choose one of two actions. Between choices each individual is informed about the success of one random other individual. We search among rules with a single round of memory for a rule that attains minimax...

We experimentally examine how the incentive to defect in a social dilemma affects conditional cooperation. In our first study we conduct online experiments in which subjects play eight Sequential Prisoner's Dilemma games with payoffs systematically varied across games. We find that few second...

Social and political inequality among individuals is a common driving force behind the breakdown in cooperation. In this paper, we theoretically and experimentally study cooperation among individuals faced with a sequence of collective-action problems in which the benefits to cooperation are...

In a set-target game, two players choose elements in some set X, and payoffs depend on whether the value of some function of these choices lies in a target set T. Typically, a set-target game has a continuum of Nash equilibria. Replacing the deterministic set T by a stochastic one and then...

We study the effects of group identity on cooperation in experimental two-person strategic games. Our results show that in games of strategic complements, group identity only matters initially when a participant interacts with another participant of the same group by delivering more cooperative...

With behavior-based pricing (BBP), retailers use customers’ purchase records to price discriminate between new and past customers. In this paper, we investigate BBP in a setting where sales channels have different purchasing convenience, indicating that channels are asymmetric. We examine how...
