The $$\kappa$$ -universalization of a symmetric game is the in which each player considers that any other chooses with probability same stategy as she. To normal form game, we associate two-stage which, first stage, roles to be played base are randomly assigned. We show pure strategy equilibrium this extended an by altruistic players (“ex ante Homo Moralis altruistic”), and converse false. pape...

Altruism was originally defi ned as a cooperative act infl icting a cost to the donor and only giving a benefi t to the recipient. However, no study has ever conclusively demonstrated the existence of altruistic behaviours that do not give any short-or long-term benefi ts to donors. Th erefore, the term altruism is generally used for costly behaviours that may potentially also be benefi cial fo...

Purpose Location-based games (LBGs) have afforded novel information technology (IT) developments in how people interact with the physical world. Namely, LBGs spurred a wave of territoriality (i.e. controlling) and exploration discovering) augmented space that are driven by different social dynamics related to group formation, connectivity altruism. The aim this study is investigate dynamic it f...

The Price of Warm Glow This paper presents a model and experimental evidence to explain the “volunteering puzzle" where agents prefer volunteering time to donating money when monetary donations are, ceteris paribus, more efficient for providing resources to charity. In the model agents receive heterogeneous utility from pure and impure altruism (Andreoni 1989) that permits warm glow to vary bet...

In order for non-kin altruism to evolve, altruists must receive fitness benefits for their actions that outweigh the costs. Several researchers have suggested that altruism is a costly signal of desirable qualities, such that it could have evolved by sexual selection. In two studies, we show that altruism is broadly linked with mating success. In Study 1, participants who scored higher on a sel...

We analyse incentives for collusive behaviour when heterogeneous providers are faced with regulated prices under two forms of yardstick competition, namely discriminatory and uniform schemes. Providers are heterogeneous in the degree to which their interests correspond to those of the regulator, with close correspondence labelled altruism. Deviation of interests may arise as a result of de-nati...

The occurrence of positive selection in schizophrenia-associated GABRB2 suggests a broader impact of the gene product on population fitness. The present study considered the possibility of cognition-related GABRB2 involvement by examining the association of GABRB2 with psychosis and altruism, respectively representing psychiatric and psychological facets of social cognition. Four single nucleot...

It is understandable that remittances are larger if the migrant is more altruistic. However, remittances that the household expects to receive, i.e. expected remittances, depend not only on remittances by the migrant, who has already moved to the host county, but also on how likely it is that a household member, a potential migrant, actually migrates. Such a probability can also be affected by ...

Human beings routinely help strangers at costs to themselves. Sometimes the help offered is generous-offering more than the other expects. The proximate mechanisms supporting generosity are not well-understood, but several lines of research suggest a role for empathy. In this study, participants were infused with 40 IU oxytocin (OT) or placebo and engaged in a blinded, one-shot decision on how ...
