Playing the trust game with other people’s money

We experimentally investigate to what extent people trust and honor trust when they are playing with other people’s money (OPM). We adopt the well-known trust game by Berg et al. (in Games Econ. Behav. 10:122–142, 1995), with the difference that the trustor (sender) who sends money to the trustee (receiver) does this on behalf of a third party. We find that senders who make decisions on behalf of others do not behave significantly different from senders in our baseline trust game who manage their own money. But receivers return significantly less money when senders send a third party’s money. As a result, trust is only profitable in the baseline trust game, but not in the OPM treatment. The treatment effect among the receivers is gender specific. Women return significantly less money in OPM than in baseline, while there is no such treatment effect among men. Moreover, women return significantly less than men in the OPM treatment.     

Achievement predictors in a secondary students’ sample

In this study several factors that influence academic achievement are going to be presented. 492 students, 190 men and 302 women, with ages from 12 to 18?years old, and from the first and third year of compulsory secondary school and the first year of voluntary secondary school have participated, completing four questionnaires about IQ, motivation, learning strategies, adjustment and study habits. The academic marks selected to be related with the questionnaires we have mentioned before were the Mathematic, Spanish Language and Grammar, English language and Physical Education. We applied the structural equation analysis, by LISREL procedure, to find the best explanatory model about the academic achievement predictors. The results show that the learning strategies and the personal adjustment do not predict the academic performance as much as the intelligence, the motivation and the study habits. Therefore, it is very important to consider these variables as predictors in the works and research, of adolescents?? achievement.
