We conduct a laboratory experiment to analyze the effect transactions costs and inertia have on charitable giving. We conjecture that transaction costs will have a greater effect on donations if the solicitation is received when the opportunity cost of time is high. Inertia could become a factor...

In the vast majority of experiments documenting the existence of reciprocity subjects are endowed with windfall funds. In some situations such endowments might create a so-called “house money effect”. We identify two reasons why the source of endowment might matter for negative reciprocity:...

We develop, and experimentally test, a behavioral model of deal- making which includes binding contracts and informal agreements as distinct but related special cases. The key assumptions: people are mostly honest; they suffer costs of overcoming temptation to renege; and they tend to split gains...

Both the law and culture make a central distinction between acts of commission that overturn the status quo and acts of omission that uphold it. In everyday life acts of commission often elicit stronger reciprocal responses than do acts of omission. In this paper we compare reciprocal responses...

Previous research has suggested that communication and especially promises in-crease cooperation in laboratory experiments. This has been taken as evidence for internal motivations such as guilt aversion or preference for promise keeping. The goals of this paper are to examine messages under a...

The hold-up problem has played a central role in the study of firm boundaries, which is a fundamental element of the economic study of organizations. We study a previously unex-plored mechanism by which integration between two parties could resolve the problem. Based on the social identity...

This paper tests Psychological Forward Induction in the Lost Wallet Game, in an attempt to explain an empirical puzzle observed by Dufwenberg & Gneezy (2000) that the size of the outside option forgone by the first mover does not affect the behavior of the second mover. This is puzzling as...

We develop and test experimentally the argument that gender/family and/or professional identities, activated through psychological priming, may influence preference for competition. We focus on female professionals for whom these identities may conflict and male professionals for whom they may...

Intent to help or harm is revealed more clearly by acts of commission that overturn the status quo than by acts of omission that uphold it. Both the law and culture make a central distinction between the two types of acts. Acts of commission elicit stronger reciprocal responses than do acts of...

This paper reports on an experiment studying the effectiveness of two types of mechanisms for promoting trust: pecuniary and non-pecuniary as well as their mutual interaction. Our data provide evidence that both mechanisms significantly enhance trust in comparison to the standard investment...
