Altruism in the (Social) Network

This paper explores the role of social integration on altruistic behavior. To this aim, we develop a two-stage experimental protocol based on the classic Dictator Game. In the first stage, we ask a group of 77 undergraduate students in Economics to elicit their social network; in the second stage, each of them has to unilaterally decide over the division of a fixed amount of money to be shared with another anonymous member in the group. Our experimental design allows to control for other variables known to be relevant for altruistic behavior: framing and friendship/acquaintance relations. Consistently with previous research, we find that subjects favor their friends and that framing enhances altruistic behavior. Once we control for these effects, social integration (measured by betweenness, a standard centrality measure in network theory) has a positive effect on giving: the larger social isolation within the group, the more likely it is the emergence of selfish behavior. These results suggest that information on the network structure in which subjects are embedded is crucial to account for their behavior.

Zaintzen garrantzia Haur Hezkuntzako lehenengo zikloan

[EUS] Gizarteak jasandako aldaketak direla eta, eskolatze goiztiarrak nabarmen egin du gora azken urteotan. Haurrak bere biziko lehen hilabeteetan gurasoengandik aldendu eta haur eskolara joan beharra dauka. Hala ere, lehen haurtzaroko edo 0-3 urte bitarteko haurren premiak ez dira Haur Hezkuntzako bigarren zikloko haurren beharrizanen berdinak eta, ondorioz, gure hezkuntza sistema egoera berri horretara egokitzen jarraitu beharra daukagu. Lan honetan haurra behatu eta tratatzeko eredu ezberdin bat aurkeztuko da, Emmi Pikler pediatrak sortutakoa eta Lóczy-n aurrera eramaten dena. Horretarako, Pikler-Lóczy pedagogia horretako atal batean, hots, eguneroko zaintzetan murgildu eta horiek sakon aztertzeari ekingo diogu. Eredu hori gure eremuko haur eskolakoetatik aldendu arren, gure jardunbidea birplanteatzeko aukera paregabea eskaintzen digu.
