    Confidence enhanced performance : does it exist and if so how does it work?
    (2010) Murad, Zahra
    We empirically test and investigate the psychological mechanism behind the theory of Confidence Enhanced Performance (Compte and Postlewaite, 2004). This theory suggests that if confidence enhances performance, then people will benefit from having the commonly observed tendency to discount past failures and be overconfident. We test this hypothesis using three tasks which require different cognitive abilities. Our findings are partially supportive of the theory. However, we cannot conclude that any of our confidence variables significantly and positively affect performance. Only in one task (the Picture Recall task) we find that enhanced mood level positively affects performance. The view that people are generally overconfident when performing tasks with imperfect feedback is not upheld. Furthermore, there seem to be strong task differences in both levels of confidence and the effects of psychological variables on performance.

    A new approach to age and risk taking behavior of agents
    (2012) Kozan, Zeynep
    In this thesis, we use evolutionary game theory techniques to analyze the relation between risk taking behavior of agents and their ages. We suppose that risk aversion is the stable pattern for the old agents and risk seeking is the stable pattern for the young agents as it is commonly assumed so in economics literature. First, we solve a benchmark model without heterogeneity in terms of age di§erentiations. In such a case, we observe that mutation either increases or decreases with respect to the payo§ levels, depending on the initial Ötness levels of the population groups. In the second step, we introduce heterogeneous population frontier. The anticipated level of the initial mutant proportion provides incentives to triger the evolution. Then, we analyze numerically the e§ects of the initial level of Ötness, initial risk averse and risk seeking proportions on the pattern of the evolution process. Finally, we studied the intertemporal e§ects of di§erent risk averse and risk seeking population proportions on mutation.
