This paper reports the results of a meta-analysis of 32 papers with results from ultimatum game experiments. We find that on average the proposer offers 40% of the pie to the responder. This share is independent of the size of the pie and of the use of the strategy method. On average 16% of the...

In this paper we import a mainstream psycholgical theory, known as attachment theory, into economics and show the implications of this theory for economic behavior by individuals in the ultimatum bargaining game. Attachment theory examines the psychological tendency to seek proximity to another...

We experimentally investigate how affective processes influence proposers' and responders' behaviour in the Ultimatum Game. Using a dual-system approach, we tax cognitive resources through time pressure and cognitive load to enhance the influence of affective processes on behaviour. We find that...

The influence of relative wealth on fairness considerations is analyzed in an ultimatum game experiment in which participants receive large and widely unequal initial endowments. Subjects initially demonstrate a concern for fairness. With time however, behavior becomes at odds with both subgame...

This paper uses responder pre-commitment and psychological type, as measured by the Myers- Briggs Type Indicator (MBTI), to gain insight into subject behavior in a laboratory ultimatum bargaining experiment. Three experiment design details are noteworthy: (1) one design requires responders to...

This paper reports the findings of a meta-analysis of 37 papers with 75 results from ultimatum game experiments. We find that on average the proposer offers 40% of the pie to the responder. This share tends is smaller for larger pie sizes and larger when a strategy method is used or when...

The stylized facts of ultimatum bargaining in the experimental lab are that offers tend to be near an equal split of the surplus and low, near perfect offers are routinely rejected. Bimmore et al (1995) use aspiration-based evolutionary dynamics to model the evolution of fair play in a binary...

Aspiration-based evolutionary dynamics have recently been used to model the evolution of fair play in the ultimatum game showing that incredible threats to reject low offers persist in equilibrium. We focus on two extensions of this analysis: we experimentally test whether assumptions about...

In this paper we import a mainstream psychological theory, known as attachment theory, into economics and show the implications of this theory for economic behavior by individuals in the ultimatum bargaining game. Attachment theory examines the psychological tendency to seek proximity to another...

We experimentally investigate how proposers in the Ultimatum Game behave when their cognitive resources are constrained by time pressure and cognitive load. In a dual-system perspective, when proposers are cognitively constrained and thus their deliberative capacity is reduced, their offers are...
