It is well-known that subjects in bilateral bargaining experiments often exhibit choice behavior suggesting there are strong reciprocators in the population. But it is controversial whether explaining this data requires a social preference model that invokes genuine strong reciprocity or whether...

This paper reports results of an incentivized laboratory experiment manipulating an extremely weak social cue in the Dictator Game. Prior to making their decision, we present dictators with a simple visual stimlulus: either three dots in a “watching-eyes” configuration, or three dots in a...

Parties in a bargaining situation may perceive guilt, a utility loss caused by receiving the larger share that is modeled in some social preferences. I extend Rubinstein (1982)'s solution of the open-ended alternating-offer bargaining problem for self-interested bargainers to a game with equally...

This note presents a solution to Rubinstein (1982)'s open-ended, alternating-offer bargaining problem for two equally patient bargainers that exhibit similar degrees of inequality aversion. Inequality-averse bargainers may perceive envy if being worse off and guilt if being better off, but they...

Bargainers in an open-ended alternating-offer bargaining situation may perceive envy, a utility loss caused by receiving the smaller share that is modeled in some social preferences in addition to self-interest. I extend Rubinstein (1982)'s original solution of the bargaining problem for two...

This paper provides an argument for the advantage of a preference for identity-consistent behaviour from an evolutionary point of view. Within a stylised model of social interaction, we show that the development of cooperative social norms is greatly facilitated if the agents of the society...

Abstract This note offers two comments on the article “Social Influences towards Conformism in Economic Experiments” by Hargreaves Heap that is to appear in the Economics e-Journal. One relates to the concept of conformism, the other lines out some phenomena where an explicit recognition of...

In many cultures and industries gifts are given in order to influence the recipient, often at the expense of a third party. Examples include business gifts of firms and lobbyists. In a series of experiments, we show that, even without incentive or informational effects, small gifts strongly...
