Abstract
This paper analyses the impact of the emergence of new funds on the portfolio decisions of mutual fund managers who are evaluated on the basis of relative performance within a dynamic model. Recent theoretical literature has pointed to the inefficiencies in portfolio selection caused by relative performance evaluation of fund managers. We find that the on-going process of creation of new funds, by posing an entry threat to the incumbent fund managers, greatly alleviates these inefficiencies. Hence the transitory market structure that characterises the mutual fund industry could explain why relative performance evaluation is widely in use.

Abstract
Using data from a large-scale field experiment, we show that while there is no gender difference in willingness to make risky decisions on behalf of a group in a sample of children, a large gap emerges in a sample of adolescents. The proportion of girls who exhibit leadership willingness drops by 39%, going from childhood to adolescence. We explore the possible factors behind this drop and find that it is largely associated with a dramatic decline in 'social confidence', measured by willingness to perform a real effort task in public.
