Eventually, the trait only represents attractiveness to mates, and no longer represents increased survival. For males, their reproductive success is limited by access to females, while A behavioural study of investment are limited by their access to resources.
He was a Fulbright Fellow at Princeton University. Experiments include testing deviations from typical simplifications of economic theory such as the independence axiom  and neglect of altruism fairness and framing effects.

The males gain ownership to the territories through male-male competition that often involves physical aggression. This term, derived from economic game theorybecame prominent after John Maynard Smith  recognized the possible application of the concept of a Nash equilibrium to model the evolution of behavioral strategies.

This behavior is seen in butterfly species such as Heliconius mepomenewhere males transfer a compound that causes the female to smell like a male butterfly and thus deter any future potential mates. Fisher's hypothesis of runaway sexual selection suggests that female preference is genetically correlated with male traits and that the preference co-evolves with the evolution of that trait, thus the preference is under indirect selection.
However, some males attempt to force copulation by grabbing females with a specialized abdominal organ without offering a gift.
Only the largest and strongest males manage to defend the best quality nest sites. This difference, in theory, should lead to each sex evolving adaptations that bias the outcome of reproduction towards its own interests. Investors display a preference for local assets with which they are more familiar local bias as well portfolios tilted toward domestic securities home bias.
