In the vast majority of laboratory experiments documenting the existence of reciprocity subjects are endowed with windfall funds. In many environments with salient fairness considerations such endowments are known to inflate subjects’ other-regarding behavior, thereby creating a so-called...

We conduct a laboratory experiment to study whether giving people more time to donate to charity reduces donations. People may intend to donate, but because of the transaction costs of doing so, postpone making the payment until they are less busy, and having postponed making the donation once,...

It has recently been argued that giving is spontaneous while greed is calculated (Rand et al. 2012). If greed is calculated we would expect that cognitive load, which is assumed to reduce the influence of cognitive processes, should affect greed. In this paper we study both charitable giving and...

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:...

A growing number of experimental studies focus on the differences between the lab and the field. Important in this issue is the role of windfall money. By conducting a dictator game, where the recipient is a charity organization, in exactly the same way in the laboratory and in the field, we...

We design a donations vs. own money choice experiment comparing three different treatments. In two of the treatments the pay-offs are hypothetical. In the first of these, a short cheap talk script was used, and subjects were required to state their own preferences in this scenario. In the...

We experimentally investigate, using a dictator game, if the effects of windfall and earned endowments on behavior differ between men and women genders. In line with previous studies, we find that windfall endowments significantly increase the amount donated. The impact of moving from earned to...

Guilt averse individuals experience a utility loss if they believe they let someone down. In particular, generosity depends on what the donor believes that the recipient expects to receive. In experimental work, several authors have identified a positive correlation between such second-order...

Social preferences have been shown to be an important determinant of economic decision making for many adults. We present a large-scale experiment with 883 children and adolescents, aged eight to seventeen years. Participants make decisions in eight simple, one-shot allocation tasks, allowing us...
