The ultimatum game has improved our understanding about the bargaining power associated with a threat, an issue where information and communication are central. This paper presents a selective review of the literature on economic experiments in the ultimatum game, organizing the major...

This paper examines the effect of message characteristics on donation behavior using an economic model of giving. The utility of giving can come from one's own contribution and possibly from the combined contributions of others. Donors are assumed to be constrained utility maximizers, and the...

The purpose of this paper is to provide a general proposition of the relationship between altruism and risk taking. As explained in the body of the paper, we diverge from a result reported in Stark et al. (2022) and provide an expansion and a generalization of a preliminary result reported in...

We analyze the offering, asking, and granting of help or other benefits as a three-stage game with bilateral private information between a person in need of help and a potential help-giver. Asking entails the risk of rejection, which can be painful: since unawareness of the need can no longer be...

There has been an increasing interest in altruistic behaviour in the domain of losses recently. Nevertheless, there is no consensus in whether the monetary losses make individuals more generous or more selfish. Although almost all relevant studies rely on a dictator game to study altruistic...

We conducted a field experiment in the natural setting of blood donations to test how oxytocin relates to empathy and altruism. We randomly assigned blood donors in the Croatian Institute for Transfusion Medicine to three groups with the aim to induce different levels of empathy by showing a...

The already uncertain supply of whole blood from donors has been made even more volatile by the COVID‐19 pandemic. Potential reasons for the persistence of this shock are unawareness of the supply drop, and fear of infection while donating. The primary aim of this study is to test efficacy of...

Social media use plays an important role in shaping individuals' social attitudes and economic behaviours. One of the first well-known examples of social media campaigns is the Ice Bucket Challenge (IBC), a charity campaign that went viral on social media networks in August 2014, aiming to...

I study attitudes towards risk taking in cases where a person relates to others positively, namely altruistically. This study is needed because it is unclear how altruism influences the inclination of an altruistic person to take risks. Will this person's risk-taking behavior differ if the...

We study a growth model with two types of agents who are heterogeneous in their degree of family altruism. We prove that every equilibrium path converges to a unique steady state, and study the effect of altruism on the properties of steady-state equilibrium. We show that aggregate income is...
