This paper is an extension of Caballer-Tarazona et al. (2016) with a novelty: A new treatment is introduced in which subjects have information about the cumulated wealth of their partners.As a complement of the educational purpose of the task, data collected during the experiment has been used to test three hypotheses on trust and reciprocity among students.Two main results emerge:First, information has no effect on trust and reciprocity decisions. And second, in median a gender effect in such decisions is found.
