Competition between groups is ubiquitous in social and economic life, and groups are typically not created equal. Here we experimentally investigate the implications of this general observation on the unfolding of symmetric and asymmetric competition between groups that are either homogeneous or...

It has been argued that in the absence of altruism, intergenerational transfers can survive only if the old are net recipients. I prove that this need not hold in an over-lapping generations model with a fixed factor. For example, the middle-aged owning land may gain by providing public...

We correlate competitive bidding and profits in symmetric independent private value first-price auctions with salivary testosterone, estradiol, progesterone, and cortisol in more than 200 subjects. Females bid significantly higher and earn significantly lower profits than males. Moreover,...
