Riassunto analitico
Ultimatum game is typically used to assess how individuals deviate from the Subgame Perfect Nash Equilibrium in the context of “leave or take” bargaining. Empirical evidences show that Receivers reject very low offer and Proposers are aware of the rejection risk and usually do not offer less than 30% of the cake. Previous studies found that emotional distance negatively affect the acceptance rate of unfair offers, while a high degree of empathy for the Proposer let Receivers accept lower offers. Information on the counterpart covers an important role in reducing (or increasing) distance among players. The following work explores the role of information about Proposers, labelled in predefined categories according to their working condition and income level. In the first phase of the study, five Proposers were picked from each category: students with no regular income, managers with a monthly income above 8000 €, retired people with a pension lower than 1000 €, associate and full professors with monthly income above 4000€ and computer-simulated proposals. In the pilot, undergraduate students were asked their opinion about each category and played sequential rounds against each Proposer. The aim of the project is to assess the effects on Receivers’ decision of social distance from Proposers, expectations and beliefs on Proposer’s category. The focus of the thesis work is on Proposers’ and Receivers’ recruitment phase, pilot and experimental setup of the next phases of the project.
